This equipment is a relatively complicated apparatus.
During rigging, installation, operation, maintenance,
or service, individuals may be exposed to certain com­ponents or conditions including, but not limited to:
heavy objects, refrigerants, materials under pressure,
rotating components, and both high and low voltage.
Each of these items has the potential, if misused or
handled improperly, to cause bodily injury or death. It
is the obligation and responsibility of rigging, instal­lation, and operating/service personnel to identify and
recognize these inherent hazards, protect themselves,
and proceed safely in completing their tasks. Failure
to comply with any of these requirements could result
in serious damage to the equipment and the property in

which it is situated, as well as severe personal injury or
death to themselves and people at the site.

This document is intended for use by owner-authorized

SECTION 1 - GENERAL CHILLER INFORMATION AND SAFETY

INTRODUCTION

Quantech QTC4 chillers are manufactured to the
highest design and construction standards ensuring
high performance, reliability and adaptability with all
types of air conditioning installations.

The unit is intended for cooling water or glycol solu­tions and is not suitable for purposes other than those
specified in this manual.

Rigging and lifting should only be done by a profes­sional rigger in accordance with a written rigging and
lifting plan. The most appropriate rigging and lifting
method will depend on job specific factors, such as the
rigging equipment available and site needs. Therefore,
a professional rigger must determine the rigging and
lifting method to be used, and it is beyond the scope of
this manual to specify rigging and lifting details.

The rigger should locate the center of
gravity through trial lifts to account
possible variations in unit configu­rations. Contact your nearest Quan­tech sales office for weight data. See
SECTION 3 - RIGGING, HANDLING
AND STORAGE for more details.

This manual contains all the information required for
correct installation and commissioning of the unit,
together with operating and maintenance instructions.
The manual should be read thoroughly before attempt­ing to operate or service the unit.

All procedures detailed in the manual, including in­stallation, commissioning and maintenance tasks must
only be performed by suitable, trained and qualified
personnel.

The manufacturer will not be liable for any injury or
damage caused by incorrect installation, commission­ing, operation or maintenance resulting from a failure
to follow the procedures and instructions detailed in
the manual.

WARRANTY

Quantech warrants all equipment and materials against
defects in workmanship and materials for a period of
eighteen months from date of shipment or 12 months
from date of startup, whichever comes first, unless
labor or extended warranty has been purchased as part
of the contract.

1

The warranty is limited to parts only replacement and
shipping of any faulty part, or sub-assembly, which has
failed due to poor quality or manufacturing errors. All
claims must be supported by evidence that the failure
has occurred within the warranty period, and that the
unit has been operated within the designed parameters
specified.

All warranty claims must specify the unit model, serial
number, order number and run hours/starts. Model and
serial number information is printed on the unit identi­fication plate.

The unit warranty will be void if any modification to
the unit is carried out without prior written approval
from Quantech. For warranty purposes, the following
conditions must be satisfied:

• The initial start of the unit must be carried out by
trained personnel from an authorized Quantech
Service Center. Refer to SECTION 6 - COMMIS-
SIONING for more information.

• Only genuine Quantech approved spare parts,
oils, coolants, and refrigerants must be used.

• All the scheduled maintenance operations detailed

in this manual must be performed at the specied
times by suitably trained and qualied personnel.

See SECTION 9 - MAINTENANCE for more in­formation.

• Failure to satisfy any of these conditions will
automatically void the warranty. Refer to Form
QTC4-NM2 for complete details.

SECTION 1 - GENERAL CHILLER INFORMATION AND SAFETY

This equipment (Class A, Group 1) is
designed and manufactured for use in
an industrial environment, in accordance
with EN 61000-6-2:2005 and EN 61000-6
4:2007 (with EN 55011:2007 limits). It is
not intended to be used on a low-voltage
public network which supplies domestic
premises. Radio frequency interference
may occur if it is used on a low voltage
public network.

This equipment equipped with VSD, may generate
conducted and radiated disturbances, which may inter­fere with or damage susceptible connected apparatus.

Generally accepted engineering standards and practic­es should be followed to ensure trouble-free and EMC
compliant electrical installation. Installations must
be supervised or completed by a competent person in
accordance with EN 13313.

Special considerations depending on the application:

• Industry standard grounding or “earthing” prac­tices for the equipment and installation

• Use of shielded or special cables (power and/or
control)

• Use of metallic conduit and/or cable trays for
power and control cables connected to equipment

• Cable segregation (in order to avoid the risk of
crosstalk or cross interference to signal cables,
the power cables shall be segregated from signal
cables)

• Dedicated isolation transformer

• Use of additional EMC lters

It is the responsibility of a designated System Integra­tor to take proper steps assuring the Electromagnetic
Compatibility of both equipment and installation as a
system.

Rotating Parts

1

Fan guards must be fitted at all times and not removed
unless the power supply has been isolated. If ductwork
is to be fitted, requiring the wire fan guards to be re­moved, alternative safety measures must be taken to
protect against the risk of injury from rotating fans.

Sharp Edges

The fins on the air-cooled condenser coils have sharp
metal edges. Reasonable care should be taken when
working in contact with the coils to avoid the risk of
minor abrasions and lacerations. The use of gloves is
recommended.

Frame rails, brakes, and other components may also
have sharp edges. Reasonable care should be taken
when working in contact with any components to avoid
risk of minor abrasions and lacerations.

Refrigerants and Oils

Refrigerants and oils used in the unit are generally non­toxic, non-flammable and non-corrosive, and pose no
special safety hazards. Use of gloves and safety glass­es is, however, recommended when working on the
unit. The buildup of refrigerant vapor, from a leak for
example, does pose a risk of asphyxiation in confined
or enclosed spaces and attention should be given to
good ventilation.

Use only the refrigerant specifically designated for the
unit. Any other type of refrigerant may cause damage
to the equipment and will void the warranty.

High Temperature and Pressure Cleaning

High temperature and pressure cleaning methods
(for example, steam cleaning) should not be used
on any part of the pressure system as this may cause
operation of the pressure relief device(s). Detergents
and solvents, which may cause corrosion, should also
be avoided.

SECTION 2 - PRODUCT DESCRIPTION

Quantech QTC4 chillers are designed for water or
glycol cooling. All units are designed to be located
outside on the roof of a building or at ground level.

The units are completely assembled with all intercon­necting refrigerant piping and internal wiring, ready
for field installation.

Prior to delivery, the unit is pressure tested, evacuated,
and fully charged with refrigerant and oil in each of the
two independent refrigerant circuits. After assembly,
an operational test is performed with water flowing
through the evaporator to ensure that each refrigerant
circuit operates correctly.

The unit structure is manufactured from heavy gauge,
galvanized steel. Many external structural parts are
coated with “Champagne” baked-on enamel powder
paint.

All exposed power wiring is routed through
liquid-tight, non-metallic conduit.

GENERAL SYSTEM DESCRIPTION

The QTC4 chiller combines the best of modern screw
compressor design with the latest technology in
variable speed drives. The result is superior control and
efficiency in real world conditions. The VSD enables
slowing the speed of the compressor to match the load
on the system resulting in precise chilled liquid con­trol, minimized sound, maximum energy efficiency,
and reduced cost of ownership. The VSD also pro­vides soft starts with no electrical inrush. The lack of
heat build-up on start also enables required off time
between starts to be reduced to a period of two minutes.

The QTC4 Air-Cooled Screw Chiller utilizes many
components, which are the same or nearly the same as
a standard screw chiller of a similar size. This includes
modular frame rails, condenser, fans, compressors and
evaporator.

The chiller consists of two screw compressors in a
corresponding number of separate refrigerant circuits,
a hybrid falling film evaporator, an air-cooled condens­er, receiver/flash tanks, feed valves, oil separators, and
compressor mufflers.

SEMI-HERMETIC QUANTECH TWIN-SCREW COMPRESSORS

Compressors are direct drive, semi-hermetic, rotary
twin-screw type, including: muffler, temperature actu­ated ‘off-cycle’ heater, IP55 terminal board and preci­sion machined cast iron housing.

Reliable suction gas cooled, high efficiency,
accessible hermetic compressor motor, full suction gas
flow through mesh screen filter, with inherent internal
thermal overload protection and external current over­load on all three phases.

Continuous function, microprocessor controlled,
Variable Speed Drive (VSD) shall provide valve-less,
smooth capacity control from 100% down to 10% of
chiller capacity.

In addition, elimination of the slide valve and asso­ciated unloading components has resulted in a 50%
reduction in compressor moving parts.

EVAPORATOR

The evaporator is a shell and tube, hybrid falling film
type heat exchanger. It contains a balance of flooded
and falling film technology to optimize efficiency, min­imize refrigerant charge, and maintain reliable control.
A specifically designed distribution system provides
uniform refrigerant flow for optimum performance.

Fan motors are Totally Enclosed Air-Over (TEAO),
squirrel-cage type and current protected. The direct
drive motors feature double-sealed and permanently
lubricated ball bearings, cutting down on maintenance
cost over the life of the unit.

REFRIGERANT CIRCUIT

An independent refrigerant circuit is provided per
compressor. Each circuit uses copper refrigerant pipe
formed on computer controlled bending machines to
reduce the number of brazed joints resulting in a reli­able and leak resistant system.

• Discharge lines are provided with a manual com­pressor shutoff service valve (See Accessories
and Options on Page 19 for suction line service
valve).

• The external oil separators, with no moving parts
and designed for minimum oil carry-over, are
mounted in the discharge line of the compressor.

• Liquid line components include: high absorp-

tion removable core lter-drier, sight glasses with

moisture indicators, manual shut-off valve with

charging port, orice and electronic expansion

valve.

• An economizer (ash) tank is located in each re-

frigerant circuit to increase the system efciency.

CONDENSER

The QTC4 introduces micro-channel coil to the
Quantech screw compressor chiller line. The micro­channel maximizes condenser heat transfer, resulting
in a smaller footprint, and reduces refrigerant charge
by as much as 50%.

Each condenser coil is a single piece all aluminum
construction including headers, tubes and fins to avoid
galvanic corrosion due to dissimilar metals. Coils and
headers are brazed as one piece. Integral sub-cooling
is included. The design working pressure is 375 PSIG
(25.9 barg).

Multiple, standard low sound, high efficiency, TEAO
motor driven fans move air through the coils. They are
dynamically and statically balanced, direct drive with
corrosion-resistant glass fiber reinforced composite
blades molded into low-noise, full airfoil cross sec­tions, providing vertical air discharge from extended
orifices for efficiency and low sound.

ELECTRICAL

Quantech has years of experience designing Variable
Speed Drives (VSDs) specifically for chiller applica­tions. The result is an extremely reliable air-cooled
chiller system that offers industry leading efficiency at
real world operating conditions, valve-less compres­sor loading/unloading, excellent capacity control, high
power factor and soft start.

Incoming single point power is standard utilizing a
lockable circuit breaker, 115VAC control transformer,
VSD, fan contactors, ON/OFF unit switch, microcom­puter keypad and display, Chiller Control and VSD
Logic boards, and relay boards.

Standard design includes IP55 rating, powder painted
steel cabinet with hinged, latched, and gasket sealed
outer doors equipped with wind struts for safer servic­ing. The panel includes a control display access door so
that display and control features can be accessed with­out opening main cabinet doors. All exposed power
wiring is routed through liquid-tight, UV-stabilized,
non-metallic conduit.

BUILDING AUTOMATION SYSTEM CAPABILITIES

The E-Link Gateway provides an economical and
versatile connection between Quantech equipment
and open/standard protocols. It efficiently man­ages the communication protocols currently used by
Quantech equipment, exposing the data in a consistent,
organized, and defined fashion. The E-Link Gateway is
available as a field-installed option on QTC4. A simple
switch selection allows configuration of the required
equipment profile and output protocol, which reduces
equipment connectivity startup time.

MICROCOMPUTER CONTROL CENTER

The microcomputer control center (see Figure 3 on
Page 18) provides automatic control of chiller

operation including compressor start/ stop and load/
unload anti-recycle timers, condenser fans, evapora­tor pump, evaporator heater, unit alarm contacts and
run signal contacts. The microcomputer control cen­ter comes online as soon as the main power switch on
the unit is switched on; immediately, the microcom­puter control center will begin to check all variables
with a frequency ranging from 30 seconds to almost
continuous monitoring.

The microprocessor controls the unit’s capac­ity by matching the actual leaving chilled water
temperature (LCWT) to the user-defined setpoint.
Factors that may cause the system’s actual LCWT to
fluctuate are changes in ambient temperature, loop
flow rate, load, and loop volume. The control system
reacts to such changes by adjusting the number of com­pressors that are on and the loading of each compressor
in order to keep the LCWT at the setpoint.

SECTION 2 - PRODUCT DESCRIPTION

Extreme Conditions – During extreme or unusual
conditions (i.e. blocked condenser coils, ambient above
scheduled maximum, etc.) the chiller control system
will avoid shutdown by varying capacity. By monitor­ing motor current and suction and discharge pressures,
the chiller can maintain maximum available cooling
output without shutting down.

Unit Safeties are provided for the chiller to perform
auto-reset shut down for the following conditions:

• Ambient temperature above or below allowable
range

• Out of range leaving chilled liquid temperature

• Under voltage

• Flow switch operation

ACCESSORIES AND OPTIONS

All options factory mounted unless otherwise noted.

Sound Attenuation

Low Noise Kits – The standard chiller configuration is
equipped with low sound fans and acoustic treatments
on the refrig erant lines and compressors. There are
several sound attenuation options available to further
reduce sound at its source thereby meeting local sound
level regulations.

SilentNight™ – Due to time of day based sound regu­lations in some locations it may be desirable to force
the chiller to a lower sound level on demand. The
SilentNight control option provides a control input
to limit sound output of the chiller based on time of
day. This feature is programmable at the chiller panel
or can be controlled remotely via a signal (4-20mA or
0-10VDC) from a BAS system.

FAN OPTIONS

Ultra Quiet Fans – The chiller is equipped with
specially designed fans and motors to provide lower
sound levels yet retain appropriate airflow. The result is
reduced fan generated sound with minimal effect on
the chiller capacity or efficiency.

High Static Fans – The chiller is equipped with
condenser fans with higher power motors suitable for
high external static pressure, up to 100 Pa (0.4 in. wa­ter), across condenser coils. This option should be se­lected if additional airflow resistance may be present
due to flow restrictions such as field installed ducts,
filters, sound enclosures etc. Please contact your local
Quantech Sales Representative for more information.

High Airflow Fans – The chiller is equipped with con­denser fans with airfoil type blades and high power mo­tors providing extra airflow across coils. In some chiller
configurations, this option can provide an increase in
chiller capacity at high ambient. The high airflow fans are
also available with variable speed control. Please contact
your local Quantech Sales Representative for more infor­mation.

CONDENSER COILS

Fin and tub condenser coils of seamless, internally-en­hanced, high-condensing-coefficient, corrosion resis­tant copper tubes are arranged in staggered rows. The
tubes are mechanically expanded into aluminum fins.
Integral subcooling is included. The design working
pressure of the coils is 350 PSIG (24 barg).

Condenser Coil Protection

The aluminum alloys used in the QTC4 micro­channel condenser have been carefully selected and
tested for high corrosion resistance. However, all met­als can corrode in harsh conditions. Consider protect­ing coils from corrosive environments such as coastal,
marine, urban and industrial.

Post-Coated Epoxy Dipped Condenser – Micro­channel condenser coils applied with electro-deposited
and baked flexible epoxy coating that is finished with a
polyurethane UV resistant top-coat suitable for highly
corrosive applications.

Protective Chiller Panels

Wire Panels – UV stabilized black polyvinyl chloride
coated, heavy gauge, welded wire mesh guards mounted
on the exterior of the full unit. Protects condenser coil
faces and prevents unauthorized access to refrigerant
components (compressors, pipes, evaporator, etc.), yet
provides free air flow. This can cut installation cost by
eliminating the need for separate, expensive fencing.

Louvered Panels – Louvered panels, painted the same
color as the unit, enclose the unit to visually screen
and protect the coils as well as preventing unauthor­ized access to internal components. Also available as a
condenser-only option.

Louvered/Wire Panels Combination – Louvered pan­els, painted the same color as the unit, are mounted on
external condenser coil faces. Heavy gauge, welded
wire-mesh panels, coated to resist corrosion, are mounted
around base of machine to restrict unauthorized access.

drain valves, close the suction service valves and leave
power to the chiller for evaporator heater mat and wa­terbox heater operation. For units without a suction
service valve, close the discharge and compressor oil
valves." on page 94 for more information on freeze
protection.

Controls Options

High Ambient Operation – This provides special
control logic coupled with high airflow fans to permit
high ambient up to 52°C (125°F) operation. Fans are
airfoil type blades with high power motors. This option
may also allow for increased machine capacity, allow­ing the selection of a smaller chassis to meet specific
capacity requirements.

setpoint can be positively offset upwards up to 22.2°C
(40°F). This option is useful for ice storage or process
applications or for periods where higher chilled liquid
temperatures are adequate for low loads. Available

and containing refrigerant under pressure. Units are
shipped without export crating unless crating has been
specified on the Sales Order.

If the unit is to be put into storage, prior to installation,
the following precautions should be observed:

• The chiller must be “blocked” so that the base is
not permitted to sag or bow.

• Ensure that all openings, such as water connec­tions, are securely capped.

• Do not store where exposed to high ambient air
temperatures that may exceed relief valve settings.

LD19197

Refer to Long-Term Storage Requirement - Field
Preparation (Form 50.20-NM7).

• The condensers should be covered to protect the

coils and ns from potential damage and corrosion,

particularly where building work is in progress.

• The unit should be stored in a location where there
is minimal activity in order to limit the risk of
accidental physical damage.

• To prevent inadvertent operation of the pressure
relief devices the unit must not be steam cleaned.

• It is recommended that the unit is periodically in­spected during storage.

INSPECTION

Remove any transit packing and inspect the unit to en­sure that all components have been delivered and that
no damage has occurred during transit. If any damage

Rigging and lifting should only be done by
a professional rigger in accordance with a
written rigging and lifting plan. The most
appropriate rigging and lifting method

will depend on job specic factors, such as

the rigging equipment available and site
needs. Therefore, a professional rigger
must determine the rigging and lifting
method to be used, and it is beyond the
scope of this manual to specify rigging
and lifting details.

LIFTING USING SHACKLES

The shackles should be inserted into the respective
holes in the base frame and secured from the inside.
Use spreader bars to avoid lifting chains hitting the
chiller. Various methods of spreader bar arrangements
may be used, keeping in mind the intent is to keep
the unit stable and to keep the chains from hitting the
chiller and causing damage. Never lift the chiller using
a forklift or by hooking to the top rails. Use only the
lifting holes provided. Lifting Instructions are placed
on a label on the chiller and on the shipping bag.

LIFTING USING LUGS

Units are provided with lifting holes in the base frame
which accept the accessory lifting lug set as shown
in the figure below. The lugs (RH and LH) should be
inserted into the respective holes in the base frame and
turned so that the spring loaded pin engages into the
hole and the flanges on the lug lock behind the hole.
The lugs should be attached to the cables/chains using
shackles or safety hooks.

5. Once the unit is completely removed from the
container, follow the professional written rigging
plan to lift the unit.

SECTION 4 - INSTALLATION

LOCATION REQUIREMENTS

For optimum performance and trouble-free service, it
is essential that the installation site meets the location
and space requirements for the model being installed.

Ensure to preserve minimum service access space for
cleaning and maintenance purposes.

OUTDOOR INSTALLATIONS

The units are designed for outdoor installation and
can be installed at ground level on a suitable flat level
foundation easily capable of supporting the weight of
the unit, or on a suitable rooftop location. In both cases
an adequate supply of air is required. Avoid locations
where the sound output and air discharge from the unit
may be objectionable.

The selected location must have minimum sun
exposure and must be away from boiler flues and
other sources of airborne chemicals that could attack
the condenser coils and steel parts of the unit.

If located in an area accessible to unauthorized
persons, steps must be taken to prevent access to the
unit by means of a protective fence. This will help
to prevent the possibility of vandalism, accidental
damage, or possible harm caused by unauthorized
removal of protective guards or opening panels to
expose rotating or high voltage components.

For ground level locations, the unit must be installed
on a suitable flat and level concrete base that extends
to fully support the two side channels of the unit
base frame. A one-piece concrete slab, with footings
extending below the frost line is recommended. To
avoid noise and vibration transmission, the unit should
not be secured to the building foundation.

On rooftop locations, choose a place with adequate
structural strength to safely support the entire operating
weight of the unit and service personnel. The unit can
be mounted on a concrete slab, similar to ground floor
locations, or on steel channels of suitable strength. The
channels should be spaced with the same centers as the
unit side and front base rails. This will allow vibration
isolators to be fitted if required. Isolators are recom­mended for rooftop locations.

Mounting holes (5/8”) are provided in the base rails for
bolting the unit to its foundation. Refer to Table 10 on
Page 78 for location of the mounting holes.

Any ductwork or attenuators fitted to the unit must
not have a total static pressure resistance, at full unit
airflow, exceeding the capability of the fans installed
in the unit.

The condenser fans are propeller-type and are not
recommended for use with ductwork, filters or other
impediments to airflow in the condenser air stream.

When it is desirable to surround the unit(s) in
addition to whatever optional louver package is
selected, it is recommended that the screening be able
to pass the required chiller CFM without exceeding

0.1"w.g. (24.9084 pa) external static pressure.

Protection against corrosive environments is
available by ordering the units with cured epoxy-coat­ing on the microchannel condenser coil. Epoxy-coated
coils should be used with any units being installed at
the seashore where salt spray / mist may hit the units,
or where acid rain is prevalent.

On installations where winter operation is intended and
snow accumulations are expected, additional elevation
must be provided to insure normal condenser air flow.

Avoid locations near windows or structures where
normal operating sounds may be objectionable.

LOCATION CLEARANCES

Adequate clearances around the unit(s) are required for
the unrestricted airflow for the air-cooled condenser
coils and to prevent re-circulation of warm discharge
air back onto the coils. If clearances given are not
maintained, airflow restriction or re-circulation will
cause a loss of unit performance, an increase in power
consumption, and may cause the unit to malfunction.
Consideration should also be given to the possibility of
down drafts, caused by adjacent buildings, which may
cause re-circulation or uneven unit airflow.

For locations where significant cross winds are
expected, such as exposed roof tops, an enclosure of
solid or louver type is recommended to prevent wind
turbulence interfering with the unit airflow.

When units are installed in an enclosure, the enclo­sure height should not exceed the height of the unit
on more than one side. If the enclosure is of louvered
construction, the same requirement of static pressure loss
applies as for ducts and attenuators stated above.

VIBRATION ISOLATORS

Optional sets of vibration isolators can be supplied
loose with each unit.

Using the Isolator tables shipped with the unit in the
information pack. Identify each mount and its correct
location on the unit.

Installation

Place each mount in its correct position and lower the
unit carefully onto the mounts ensuring the mount
engages in the mounting holes in the unit base frame.

On adjustable mounts, transfer the unit weight even­ly to the springs by turning the mount adjusting nuts
(located just below the top plate of the mount) counter­clockwise to raise and clockwise to lower. This should
be done two turns at a time until the top plates of all
mounts are between 1/4" (6 mm) and 1/2" (12 mm)
clear of top of their housing and the unit base is level.

SHIPPING BRACES

The chiller’s modular design does not require shipping
braces.

CHILLED LIQUID PIPING

General Requirements

The following piping recommendations are intended to
ensure satisfactory operation of the unit(s). Failure to
follow these recommendations could cause damage to
the unit, or loss of performance, and may invalidate the
warranty.

The maximum ow rate and pressure drop

for the evaporator must not be exceeded at
any time. Refer to SECTION 5 - TECHNI­CAL DATE on page 57 for details.

The Maximum acceptable Chilled Liquid
pressure in the inlet of Evaporator is same
as the statement in "Maximum Tube Side
Pressure" of Pressure Vessel Name Plate
for QTC4 with Falling Film Evaporator.

There should be a straight run of piping of at least 5
pipe diameters on either side. The flow switch should
be wired to Terminals 2 and 13 on the 1TB terminal
block. A flow switch is required to prevent damage to
the evaporator caused by the unit operating without ad­equate liquid flow.

The flow switch used must have gold plated contacts
for low voltage/current operation. Paddle type flow
switches suitable for 10 barg (150 PSIG) working pres­sure and having a 1" N.P.T. connection can be obtained
from Quantech as an accessory for the unit. Alterna­tively, a differential pressure switch fitted across an
orifice plate may be used, preferably of the high/low
limit type.

The chilled liquid pump(s) installed in the piping
system(s) should discharge directly into the unit evap­orator section of the system. The pump(s) may be con­trolled by the chiller controls or external to the unit.

Pipework and fittings must be separately supported to
prevent any loading on the evaporator. Flexible con­nections are recommended which will also minimize
transmission of vibrations to the building. Flexible
connections must be used if the unit is mounted on
anti-vibration mounts, as some movement of the unit
can be expected in normal operation.

Piping and fittings immediately next to the evaporator
should be readily de-mountable to enable cleaning be­fore operation, and to facilitate visual inspection of the
exchanger nozzles.

The evaporator must be protected by a

strainer, preferably of 16 mesh, tted as

close as possible to the liquid inlet con­nection, and provided with a means of
local isolation.

The evaporator must not be exposed to flushing
velocities or debris released during flushing. It is
recommended that a suitably sized bypass and valve
arrangement is installed to allow flushing of the piping
system. The bypass can be used during maintenance to
isolate the heat exchanger without disrupting flow to
other units.

4

QUANTECH

The liquid must enter evaporator at the
inlet connection. The standard inlet con­nection is opposite the control panel end

of the evaporator. A ow switch must be

installed in the customer piping at the
outlet of the evaporator and wired back
to the control panel using shielded cable.

Thermometer and pressure gauge connections should
be provided on the inlet and outlet connections of each
evaporator. Gauges and thermometers are not provided
with the unit and are to be furnished by others.

Drain and air vent connections should be provided at
all low and high points in the piping to permit drainage
of the system and to vent any air in the pipes.

37

SECTION 4 - INSTALLATION

FORM QTC4-NM1

ISSUE DATE: 4/2/2018

Liquid system lines at risk of freezing, due to low am­bient temperatures should be protected using insula­tion and heater tape and/or a suitable glycol solution.
The liquid pump(s) may also be used to ensure liquid
is circulated when the ambient temperature approaches
freezing point.

Insulation should also be installed around the evapora­tor nozzles. Heater tape of 21 Watts per meter under
the insulation is recommended, supplied independently
and controlled by an ambient temperature thermostat
set to switch ON at approximately 2.2°C (4°F), above
the freezing temperature of the chilled liquid.

Evaporator heater mats are installed under the insula­tion, and are powered from the chiller's control panel.
In sub-freezing conditions, unless the evaporator has
been drained or an appropriate water-to-glycol concen­tration is maintained, high voltage power to the chill­er must be kept on to ensure the heater mats assist in
evaporator freeze protection. If there is a potential for
power loss, Quantech recommends that the evaporator
is drained or that water in the chilled water circuit be
replaced with an appropriate water-to-glycol concen­tration.

Any debris left in the water piping be­tween the strainer and evaporator could
cause serious damage to the tubes in the
evaporator and must be avoided. Be sure
the piping is clean before connecting it to
the evaporator. Keep evaporator nozzles
and chilled liquid piping capped prior to
installation to assure construction debris
is not allowed to enter.

The installer/user must also ensure that
the quality of the water in circulation is
adequate, without any dissolved gases,
which can cause oxidation of steel or cop­per parts within the evaporator.

WATER TREATMENT

The unit performance provided in the Design Guide is
based on a fouling factor of 0.018m2/hr °C/kW (0.0001
ft2hr°F/Btu). Dirt, scale, grease and certain types of wa­ter treatment will adversely affect the heat exchanger
surfaces and therefore the unit performance. Foreign
matter in the water system(s) can increase the heat ex­changer pressure drop, reducing the flow rate and caus­ing potential damage to the heat exchanger tubes. Aer­ated, brackish or salt water is not recommended for use
in the water system(s).

Quantech recommends that a water treatment specialist
should be consulted to determine whether the proposed
water composition will adversely affect the evaporator
materials of carbon steel and copper. The pH value of
the water flowing through the evaporator must be kept
in a range between 7 and 8.5.

MINIMUM WATER VOLUME

It is good practice to include as much water volume as
possible in a chilled water loop. This increases the ther­mal mass and “Flywheel” effect within the system (that
is: the more; the better) which in turn promotes stable
water temperature control and increases reliability by
reducing compressor cycling.

For air conditioning applications, a minimum of 3 gal­lons/ton is required. It is preferred that the gallon/ton
ratio be within the 5 to 8 range. For process applica­tions, a minimum of 6 gallons/ton ratio is required with
preference towards a range of 7 to 11. Install a tank or
increase pipe sizes to provide sufficient water volume.

LEAVING WATER TEMPERATURE OUT OF RANGE

The QTC4 chiller line has a maximum leaving water
temperature of 15.6°C (60°F). Where process applica­tions require a chilled water temperature higher than
what the chiller provides, a simple piping change can
remove the problem. By using a mixture of chiller­cooled water and returning process water, the chilled

38

water entering the process can be held at the desired
temperature. A tank can also be used to meet high leav­ing water temperature requirements.

FLOW RATE OUT OF RANGE

Each QTC4 evaporator has a minimum and maximum
flow rate. Some process applications require a flow
rate that is out of range for the evaporator. In those ap­plications, a piping change can remove the problem.

In applications where the required flow rate is less than
the evaporator’s minimum allowable, the chilled water
can be recirculated to the chiller.

In applications where the required flow rate is greater
than the evaporator’s maximum allowable, the chilled
water can be recirculated to the load.

THERMAL STORAGE

Thermal storage is the practice of storing cooling ener­gy during a period of little or no load and/or low energy
costs for use during periods of high load and/or energy
costs. Conventional cooling systems produce cooling
when it is needed which is commonly during times of
peak demand. Thermal storage allows generation of
cooling capacity to occur during off-peak periods and
store that capacity to meet future cooling requirements.
Using thermal storage can result in smaller equipment
sizes, thereby reducing capital cost, and also can result
in significant energy cost savings

The QTC4 has special control logic to be able to pro­duce chilled leaving brine temperatures below 4.4°C
(40°F) so as to supply a storage tank with chilled liq­uid during times of low demand. QTC4 chillers selected
for thermal storage operation can also be selected to
efficiently provide chilled fluid at nominal cooling loads.

VARIABLE PRIMARY FLOW

Quantech recommends a maximum 10% per minute
flow rate of change, based on design flow, for variable
primary flow applications. Provide 8 to 10 gallons per
chiller ton (8.6 to 10.8 liter per cooling KW) system wa­ter volume. Insufficient system volume and rapid flow
changes can cause control problems or can even cause
chiller shutdowns. There are many other design issues
to evaluate with variable primary flow systems. Consult
your Quantech Sales Representative for more informa­tion about successfully applying QTC4 chillers.

If relief piping is common to more than one valve, its
cross-sectional area must be at least the total required
by each valve. Valve types should not be mixed on a
common pipe. Precautions should be taken to ensure
the outlets of relief valves or relief valve vent pipes
remain clear of obstructions at all times.

ELECTRICAL CONNECTION

The following connection recommendations are
intended to ensure safe and satisfactory operation of
the unit. Failure to follow these recommendations
could cause harm to persons or damage the unit, and
may invalidate the warranty.

No additional controls (relays, etc.)
should be mounted in the control panel.
Power and control wiring not connected
to the control panel should not be run
through the control panel. If these pre­cautions are not followed it could lead to
a risk of electrocution. In addition, elec­trical noise could cause malfunctions or
damage the unit and its controls.

4

REFRIGERANT RELIEF VALVE PIPING

The evaporator is protected against internal refrigerant
overpressure by refrigerant relief valves. A pressure
relief valve is mounted on each of the main refrigerant
lines connecting the evaporator to the compressors.

A piece of pipe is fitted to each valve and directed so
that when the valve is activated the release of high
pressure gas and liquid cannot be a danger or cause
injury. For indoor installations (not recommended),
pressure relief valves should be piped to the exterior
of the building.

The size of any piping attached to a relief valve must
be of sufficient diameter so as not to cause resistance to
the operation of the valve. Unless otherwise specified
by local regulations. Internal diameter depends on the
length of pipe required and is given by the following
formula:

D5 = 1.447 x L

Where:

• D = minimum pipe internal diameter in cm

• L = length of pipe in meters

After power wiring connection, do not
switch on mains power to the unit. Some
internal components are live when the
mains are switched on and this must
only be done by “Authorized” persons
familiar with starting, operating, and
troubleshooting this type of equipment.

POWER WIRING

All electrical wiring should be carried out in accor­dance with local regulations. Route properly sized
cables to cable entries on the unit.

In accordance with local codes, NEC codes, U.L. and
C.E. standards, it is the responsibility of the user to
install over current protection devices between the
supply conductors and the power supply terminals on
the unit.

To ensure that no eddy currents are set up in the power
panel, the cables forming the 3-phase power supply
must enter via the same cable entry.

All sources of supply to the unit must be
taken via a common point of isolation
(not supplied by Quantech).

Copper power wiring only should be used for supply­ing power to the chiller. This is recommended to avoid
safety and reliability issues resulting from connection
failure at the power connections to the chiller. Alumi­num wiring is not recommended due to thermal char­acteristics that may cause loose terminations result­ing from the contraction and expansion of the wiring.
Aluminum oxide may also build up at the termination
causing hot spots and eventual failure. If aluminum
wiring is used to supply power to the chiller, AL-CU
compression fittings should be used to transition from
aluminum to copper. This transition should be done in
an external box separate to the power panel. Copper
conductors can then be run from the box to the chiller.

Caulk power and control wiring conduit
entering the power panel to assure moist
air from the building cannot enter the
panel.

POWER SUPPLY WIRING

Units require only one 3-phase supply, plus earth.

Connect the 3-phase supplies to the circuit breaker
located in the panel (See Table 4 on Page 47).

Connect a suitably sized earth wire to the PE terminal
in the panel.

CONTROL WIRING

All control wiring utilizing contact closures to the con­trol panel terminal block is nominal 115VAC and must
be run in shielded cable, with the shield grounded at
the panel end only, and run in water tight conduit. Run
shielded cable separately from mains cable to avoid
electrical noise pick-up. Use the control panel cable
entry to avoid the power cables.

Voltage free contacts connected to the panel must be
suitable for 115VAC10 ma (gold contacts recommend­ed). If the voltage free contacts form part of a relay or
contactor, the coil of the device must be suppressed using
a standard R/C suppressor. The above precautions must
be taken to avoid electrical noise, which could cause a
malfunction or damage to the unit and its controls.

VOLTS FREE CONTACTS

Chilled Liquid Pump Starter

Terminals 23 and 24 on 1TB close to start the chilled
liquid pump. This contact can be used as a master start/
stop for the pump in conjunction with the daily start/
stop schedule. Cycle the pumps from the unit panel if
the unit will be operational or shut-down during sub­freezing conditions. Refer to the Evaporator Pump
Control on Page 96 for more information on testing
the pumps.

115VAC CONTROL SUPPLY TRANSFORMER

A 3-wire high voltage to 115VAC supply transformer
is standard in the chiller. This transformer is mounted
in the cabinet and steps down the high voltage supply
to 115VAC to be used by the Controls, VSD, Feed and
Drain Valve Controller, Valves, Solenoids, Heaters, etc.

The high voltage for the transformer primary is
taken from the chiller input. Fusing is provided for the
transformer.

Removing high voltage power to the
chiller will remove the 115VAC supply
voltage to the control panel circuitry
and the evaporator heater mat. In sub­freezing weather, this could cause serious
damage to the chiller due to evaporator
freeze-up. Do not remove power unless
alternate means are taken to ensure op­eration of the control panel, evaporator
heater mat, and waterbox heaters.

Run Contact

Terminals 21 and 22 on 1TB close to indicate that a
system is running.

Alarm Contacts

Each system has a single voltage-free contact, which
will operate to signal an alarm condition whenever any
system locks out, or there is a power failure. To obtain
system alarm signal, connect the alarm circuit to volt
free Terminals 25 & 26 (Sys 1), Terminals 27 and 28
(Sys 2) of 1TB.

SYSTEM INPUTS

Flow Switch

A chilled liquid flow switch of suitable type MUST be
connected between Terminals 2 and 13 of 1TB to pro­vide protection against loss of liquid flow, which will
cause evaporator freeze-up if the chiller is permitted
to run. The flow switch circuitry is a 115VAC circuit.
Contacts must be rated for low current (5mA). Gold
contacts should be used.

between Terminals 2 and 15 of 1TB and System 2 dry
contacts are connected between Terminals 2 and 16 of
1TB. If remote start/stop is not utilized, a jumper must
be paced across the terminals to allow the system to
run. The remote run/stop circuitry is a 115VAC circuit.
Contacts must be rated for low current (5mA). Gold
contacts should be used.

Remote Print

Closure of suitable contacts connected to Terminals
2 and 14 of 1TB will cause a hard copy printout of
Operating Data/Fault History to be made if an optional
printer is connected to the RS-232 port. The remote print
circuitry is a 115VAC circuit. Contacts must be rated for
low current (5mA). Gold contacts should be used.

Optional Remote Setpoint Offset – Temperature

A voltage signal connected to Terminals 17 and 18 of
1TB will provide a remote offset function of the chilled
liquid setpoint, if required.

Optional Remote Setpoint Offset – Current

A voltage signal connected to Terminals 19 and 20

SECTION 6 - COMMISSIONING

PREPARATION

Commissioning of this unit should only
be carried out by Quantech Authorized
personnel.

Commissioning personnel should be thoroughly
familiar with the information contained in this docu­ment before starting the unit.

The following basic checks should be made with the
customer power to the unit switched OFF.

Proper electrical lock out and tag out
procedures must be followed.

Inspection

Correct System Refrigerant Charge

The charge on a system should always be checked
when operating for several minutes at full speed with
the system stable. Stable conditions are defined as
operation without fan cycling, economizer cycling, VI
solenoid cycling, or any other system transient condi­tions. Ideal refrigerant charge will be reached when the
refrigerant level in the evaporator is near the middle of
the evaporator sight glass.

Refrigerant should not be added or
removed unless the level is at the bottom
or the top of the glass. It is not necessary to
weigh charge unless the entire charge has
been lost. The ease of charging is possible
since the microchannel coils hold only a
small amount of refrigerant charge. A

charging valve is located between the xed
orice and the evaporator for adjusting

charge. Charge should be added as liquid

with the pump ON and liquid owing

through the evaporator.

6

Inspect unit for installation damage. If found, take
action and/or repair as appropriate.

Refrigerant Charge

Packaged units are normally shipped as standard with
a full refrigerant operating charge. Check that refrig­erant pressure is present in both systems and that no
leaks are apparent. If no pressure is present, a leak test
must be undertaken, the leak(s) located and repaired.

Do not evacuate or liquid charge with static water in
the evaporator. Turn the pump on. Take care to liq­uid charge slowly to avoid excessive thermal stress
at the charging point and to assure the refrigerant
temperature in the evaporator does not go below the
freezing point with liquid refrigerant in the evapo­rator. Once the vacuum is broken, charge into the
evaporator or flash tank with the Condenser Drain
Valve (Flash Tank Feed) open and the chilled liquid
pump ON to the full operating charge, as detailed in
SECTION 5 - TECHNICAL DATA.

Service and Oil Line Valves

Open each compressor oil, economizer, and discharge
ball or service valves. If valves are of the back-seat
type, open them fully (counterclockwise) then close
one turn of the stem to ensure operating pressure is fed
to pressure transducers.

Compressor Oil

To add oil to a circuit - connect a hand oil pump
(Part No. 470-10654-000) to the 1/4" (6.35 mm) oil
charging valve on the oil separator piping with a length
of clean hose or copper line, but do not tighten the flare
nut. Using clean oil of the correct type (“L” oil), pump
oil until all air has been purged from the hose then
tighten the nut. Stroke the oil pump to add oil to the oil
system. While the compressor is running at full speed,
the oil level should be visible in the sight glass of the
oil separator. Approximately 2 to 3.1 gallons (7.5 to

11.6 liters) are present in each refrigerant system.

SECTION 6 - COMMISSIONING

FORM QTC4-NM1

ISSUE DATE: 4/2/2018

Avoid levels in either oil separator that are above
the middle of the top sight glass. This may cause
excessive oil carryover in the system. High oil concen­tration in the system may cause nuisance trips resulting
from incorrect readings on the level sensor and tem­perature sensors. Temperature sensor errors may result
in poor liquid control which will result in liquid over­feed and subsequently damage the compressor. High
oil carryover may also cause liquid to be returned to the
compressor, which can damage the compressor.

Fans

Check that all fans are free to rotate and are not dam­aged. Ensure blades are at the same height when
rotated. Ensure fan guards are securely fixed.

If condenser fans are manually operated
in VFD mode, manually turn on all 4 fan
digital outputs before enabling fan control
voltage output. Damage to a fan contactor
or fan VFD may occur if this instruction
is not followed.

plugged air vent mounted on the top of the evaporator
body.

Flow rates and pressure drops must be within the limits
given in SECTION 5 - TECHNICAL DATA. Operation
outside of these limits is undesirable and could cause
damage.

If main power must be switched OFF for maintenance
or shutdown, precautions must be taken. See Unit

Maintenance and Shutdown in Sub-freezing Conditions
on Page 94. Before placing the unit back in service,

valves should be opened and power must be switched
on (if power is removed for more than 8 hours) for at
least 8 hours (24 hours if ambient temperature is below
86°F [30°C]) before the unit is restarted.

Flow Switch

Verify a chilled water flow switch is correctly fitted
in the customer’s piping on the evaporator outlet, and
wired into the control panel correctly using shielded
cable.

Isolation / Protection

Verify all sources of electrical supply to the unit are
taken from a single point of isolation. Check that the
maximum fuse sizes recommended in SECTION 5 -
TECHNICAL DATA has not been exceeded.

Control Panel

Check the panel to see that it is free of foreign materi­als (wire, metal chips, etc.) and clean out if required.

Power Connections

Check that the customer power cables are connected
correctly to the terminal blocks or optional circuit
breaker. Ensure that connections of power cables within
the panels to the circuit breaker or terminal blocks are
tight.

Grounding

Verify that the unit’s protective ground terminal(s) are
properly connected to a suitable grounding point. En­sure that all unit internal ground connections are tight.

Water System

Verify the chilled liquid system has been installed cor­rectly, and has been commissioned with the correct di­rection of water flow through the evaporator. The inlet
should be at the bottom connection on a two pass evapo­rator. Purge air from the top of the evaporator using the

There should be a straight run of at least five pipe diam­eters on either side of the flow switch. The flow switch
should be connected to Terminals 2 and 13 in the panel.

Temperature Sensor(s)

Ensure the leaving liquid temperature sensor is coated
with heat conductive compound (Part No. 013-00890-

000) and is inserted to the bottom of the water out­let sensor well in the evaporator. This sensor is part
of the pump control freeze protection operation. It
provides some freeze protection and must always be fully
inserted in the water outlet sensor well.

Programmed Options

Verify that the options factory-programmed into the
Micro Panel are in accordance with the customer’s
order requirements by pressing the OPTIONS key on
the keypad and reading the settings from the display.

Programmed Settings

Ensure the system cutout and operational settings are in
accordance with the operating requirements by press­ing the PROGRAM key.

Date and Time

Program the date and time by first ensuring that the CLK
jumper JP2 on the Chiller Control Board is in the ON
position. Then press the DATE/TIME key and set the
date and time (See Date/Time and Schedule Keys on

Start/Stop Schedule

Program the daily and holiday start/stop by pressing
the SCHEDULE key (See Date/Time and Schedule
Keys on Page 140 for more details on programming
the date and time).

Setpoint and Remote Offset

Set the required leaving chilled liquid temperature
setpoint and Control Range under the SETPOINTS key.
The chilled liquid temperature control settings need to
be set according to the required operating conditions.

If remote temperature reset (offset) is to be used, the
maximum reset required must be programmed by
pressing the SETPOINTS key (See Setpoints Key on
Page 132).

FIRST TIME START UP

During the commissioning period there
should be sufficient heat load to run
the unit under stable full load operation
to enable the unit controls, and system
operation to be set up correctly, and a
commissioning log taken.

and display the nature of the fault.

Oil Pressure

When a compressor starts, press the relevant “System
Pressures” key and verify that oil differential pressure
(oil pressure-suction pressure) develops immediately.
If oil pressure does not develop, the automatic con­trols will shut down the compressor. Under no circum­stances should a restart attempt be made on a compres­sor, which does not develop oil pressure immediately.
Switch the UNIT switch to the OFF position.

Loading

Once the unit has been started, all operations are fully
automatic. After an initial period at minimum capacity,
the control system will adjust the unit load depending
on the chilled liquid temperature and rate of tempera­ture change. If a high heat load is present, the control­ler will increase the speed of the compressor(s).

Condenser and Fan Rotation

Once a compressor is running, discharge pressure
rises as refrigerant is pumped into the air-cooled con­denser coils. This pressure is controlled by stages of
fans to ensure maximum unit efficiency while main­taining sufficient pressure for correct operation of the
condensers and the lubrication system.

6

Interlocks

Verify that liquid is flowing through the evaporator
and that heat load is present. Ensure that any remote
run interlocks are in the run position and that the Daily
Schedule requires the unit to run or is overridden.

Unit Switch

Place the UNIT switch on the keypad to the ON position.

Startup

Press the SYSTEM SWITCHES key and place the
system switch for System 1 to the ON position. There
may be a few seconds delay before the first compres­sor starts because of the anti-recycle timer). Be ready
when each compressor starts, to switch the UNIT
switch OFF immediately, if any unusual noises or
other adverse conditions develop.

When a compressor is running, the controller monitors
oil pressure, motor current, and various other system
parameters such as discharge pressure, chilled liquid
temperature, etc. Should any problems occur; the con­trol system will immediately take appropriate action

As discharge pressure rises, the condenser fans operate
in stages or ramp up in speed to control the pressure.
Verify that the fans operate in the correct direction of
rotation and operation is correct for the type of unit.

System Charge

Check system charge at steady full compressor load
only. It is important that all fans are running for the
system. The refrigerant level in the evaporator should
be about in the middle of the sight glass. Unless
levels are at the bottom or the top of the sight glass,
they should not cause concern or require adding or
removing charge.

GENERAL OPERATION

After completion of the above checks for System 1,
switch OFF the SYS 1 switch on the keypad and repeat
the process for each subsequent system. When all run
correctly, stop the unit, switch all applicable switches
to the ‘ON’ position and restart the unit.

Assure all checks are completed in the Equipment
Pre - Startup and Startup Checklist. The chiller is then
ready to be placed into operation.

Operation in Sub-freezing Conditions

The QTC4 may be operated in sub-freezing conditions
if the following freeze protections are taken:

A. A suction service valve electric actuator is

installed. Chiller software will operate the
actuator in order to protect against freezing due to
evaporator refrigerant migration.

-or-

B. No suction service valve is installed but the water

circuit valves are kept open, there is continuous
power to the chiller and pump for chilled water
pump control, and the pump will operate and cir­culate water through the evaporator whenever
commanded by the chiller.

The above operation is only advised if
uninterrupted power can be ensured.
Unforeseen power interruptions can
damage the evaporator in a very short
time frame if the temperature falls below
freezing.

Unit Maintenance and Shutdown in Sub­freezing Conditions

If the QTC4 is maintained or shut down and will be
subjected to sub-freezing conditions, it is critical to
protect against evaporator and waterbox freeze dam­age. Quantech recommends the following options (in
order of freeze protection level) be performed on each
circuit.

A. Glycol: Replace water with an appropriate water

to glycol concentration of antifreeze.

-or-

B. Drain: Remove power to the waterbox heaters.

Close the water valves, drain the evaporator, and
leave the evaporator drain valves open.

-or-

C. Refrigerant Valve - Off: Close the water valves,

close ash tank drain valves, close the suction

service valves and leave power to the chiller for
evaporator heater mat and waterbox heater op­eration. For units without a suction service valve,
close the discharge and compressor oil valves.

If there is potential for power loss, Quantech recom­mends the water in the chilled water circuit be replaced
with an appropriate water-to-glycol concentration.

Failure to follow Quantech freeze pro­tection recommendations can void the
warranty.

-or-

D. Pump Control: Keep power to the chiller in or-

der to have control over chilled water pumps and
heater operation and leave the water circuit valves
open. This will enable water to circulate through
the evaporator to avoid freezing.

Options A and B are the recommended
processes for unit maintenance and
shutdown. Unforeseen power interrup­tions can damage the evaporator in a very
short time frame if the temperature falls
below freezing.

must time out before the system is allowed to restart.

Evaporator Pump Control

The evaporator pump dry contacts are energized when
any of the following conditions are true:

• If a Low Leaving Chilled Liquid Fault occurs.

• Whenever a compressor is running.

• The Daily Schedule is ON and the UNIT switch
is ON.

Even if one of above is true, the pump will not run if
the panel has been powered up for less than 30 seconds
or if the pump has run in the last 30 seconds to prevent
pump motor overheating.

Evaporator Heater Control

The evaporator heater is controlled by ambient
air temperature. If no systems are running and the
ambient temperature drops below 4.4 °C (40°F), the
heater is turned ON. If no systems are running and
the temperature rises above 7.2°C (45°F) the heater is
turned OFF. Whenever a system is running, the evapo­rator heater is turned OFF.

SECTION 7 - OPERATION

Both evaporator heater outputs will always be turned
ON and OFF together. An under voltage condition will
keep the heater OFF until full voltage is restored to the
system.

Compressor Heater Control

Each compressor has its own heater. The purpose of
the heater is to assure refrigerant does not condense
in the compressor. There is no oil sump, but refriger­ant could possibly condense in the rotors or the motor
housing. The heater will be OFF whenever the respec­tive compressor is running. As soon as the compressor
shuts OFF, the heater will turn ON as long as all motor
temperature sensors in the compressor read less than
70°C (158°F). The heater will turn OFF, if any internal
compressor motor temperature sensor reads more than

71.1°C (160°F).

Alarms

Each system has its own alarm. The Alarm output is ON
(dry contact closed) when no fault condition is pres­ent and OFF (dry contact open) to indicate an alarm
situation. The Alarm will be activated (contacts open),
if any of the following are true.

• A System is faulted or inhibited from starting for
more than 5 seconds.

• The Unit is faulted or inhibited from starting for
more than 5 seconds.

• A System is locked out.

• The Unit is locked out.

• Power is removed from the chiller.

Chiller Run Contact

The Chiller Run dry contact is closed whenever any sys­tem is running. It is open when all systems are shut OFF.

Flow Switch Control

A chilled liquid flow switch of suitable type MUST
be connected between Terminals 2 and 13 of 1TB to
provide protection against loss of liquid flow, which
will cause evaporator freeze-up if the chiller is permit­ted to run.

Remote Run / Stop

A Remote Run/Stop input is available for each system.

BASIC OPERATING SEQUENCE

Start Sequence and Loading

To initiate the start sequence of the chiller, the follow­ing conditions must be satisfied before the precharge
of the DC Bus will take place:

• UNIT SWITCH must be ON.

• At least one System Switch is ON

• Run permissive inputs (Remote Cycling
Contacts) must be closed.

• No unit faults exist.

• No unit start inhibits exist.

• At least one system not faulted or inhibited.

• The Daily Schedule is calling for the chiller to
run.

• The Flow Switch is closed.

• Leaving Chilled Liquid Setpoint is above the
Setpoint plus CR (Setpoint High Limit).

Once the precharge takes place, if the anti-recycle tim­er is timed out the chiller control system on the Chiller
Control Board will select the number of compressors
to start and begin operation of the compressors. The
compressor(s) speed will be ramped to the minimum
start frequency and increase speed as needed in an ef­fort to regulate the leaving chilled liquid temperature
to meet the desired Setpoint. Unit Warnings

UNIT WARNING

Unit Warning Operation

Unit warnings are caused when a condition is pres­ent requiring operator intervention to restart the unit.
All setpoints, program values, and options should be
checked before operating the unit. Warnings are not
logged to the history buffer. If a unit warning is in
effect, the message will be displayed to the operator
when the STATUS key is pressed.

Low Battery Warning

The LOW BATTERY WARNING can only occur at
unit power-up. On micropanel power-up, the RTC bat­tery is checked to see if it is still operational. If it is,
normal unit operation is allowed. If the battery volt­age is determined to be low, the following warning
message is displayed indefinitely.

SECTION 7 - OPERATION

FORM QTC4-NM1

ISSUE DATE: 4/2/2018

If a low battery condition exists, all programmed
setpoints, program values, time, schedule, and history
buffers will have been lost. These values will all be
reset to their default values, which may not be the
desired operating values. Once a bad battery is detect­ed, the unit will be prevented from running until the
MANUAL OVERRIDE key is pressed. Once the
MANUAL OVERRIDE key is pressed, the anti
recycle timers will be set to the programmed default anti
recycle time to allow the operator sufficient time to
check setpoints, program values, etc.

If a low battery is detected, it should be replaced as
soon as possible. The programmed values will all be
lost and the unit will be prevented from running on the
next power interruption.

MICROBOARD (331-03478-XXX)

The 331-03478-xxx microboard was developed as
a direct replacement for the 031-02478-xxx line of
microboards. No adapter harness is required when
replacing a 02478 with the new 03478. The 03478
microboard uses the IPUII processor card and provides
new features for the chillers, that the 02478 did not
have.

The 03478 program resides in flash memory instead
of EPROM. Program updates are accomplished by
loading the new program from an SD card inserted into
the SD card reader/writer. This same SD card reader/
writer also allows the user to datalog the operating
parameters to an SD card every 5 seconds. This
information is invaluable when troubleshooting
unit and system problems since it allows the service
technician to view operating parameters prior to a unit
fault.

Details on the new datalogging capability are explained
in the OPTIONS Key area of this manual. A Real Time
Clock/BRAM keeps time and setpoints during power
outages.

Refer to Figure 18 on Page 99, to locate the follow­ing ports of the 03478 microboard.

POWER – On solid indicates that the base board +12V
and +5V power supplies are operational.

TX1 – Red LED flashes when transmitting data out
Port 1 TB3 (Future native communications BAS port).

RX1 – Green LED flashes when receiving data in Port
1 TB3 (Future native communications BAS port).

TX2 – Red LED that flashes when transmitting data
out Port 2 (E-Link TB2 or printer TB1).

RX2 – Green LED that flashes when receiving data in
Port 2 (E-Link TB2 or printer TB1).

VSD_TX – Red LED that flashes when transmitting
data out Port 3 to the VSD Logic board.

VSD_RX – Green LED that flashes when receiving
data in Port 3 from the VSD Logic board.

Power Supply Test Points

24VAC power is applied to the 331-03478-xxx
microboard connector J12 and is used to create vari­ous DC power sources required by the microboard
circuitry. If the chiller control is malfunctioning,
the power supply test points should be measured to
determine the status of the microboard.

TP1 GND (Measure TP2, TP3, TP4 and TP5 in refer­ence to this Test Point)

TP2 +3.3V [3.2 to 3.4VDC] provides power to the
processors

TP3 +5V [4.8 to 5.2VDC] power communication ports
2,3 and 4 and analog sensors

TP4 +12V [11.64 to 12.36VDC] powers the display
and backlight and is regulated to become the +5V

TP5 +15V [11.3 to 16.6VDC] powers the analog out­puts to the EEV valves

Configuration Jumpers

The same configuration jumpers that existed on the
02478 are provided on the 03478.

Power Supplies and LEDs

The 03478 has LEDs to indicate various states of
operation of the microboard.

STATUS – Flashes every ½ second to indicate that the
base board processor is running its program.

Communication Ports

The 03478 microboard has the following native
communication ports.

TB3 Port 1 Native BAS RS-485.

SW1 RS-485 Biasing Switch for Port. Set to ON if

Chiller is in an End Of Line position on the network.

U26 is the Port 1 RS-485 Driver Chip. It is
socketed to allow field replacement. RX1 and TX1
LEDs illuminate to indicate Port 1 communications
activity.

BUILDING AUTOMATION SYSTEM (BAS) COMMUNICATIONS

There are three different ways the chiller communi­cates to the BAS.

• Via board Native Communication protocol

• Using an E-Link Gateway

• Using an SC-EQ Communication Card

To access the Port communication parameters:

1. Press the PROGRAM key once.

2. Enter password 5255.

3. Press the (ENTER) key to display the Port 1

(P1) settings.

Set the following parameters:

1. DE Modier Address (number entered is
multiplied by 100): set as required by network.

2. DE Modier Offset (number entered is added to
DE Modier Address): set as required by net­work (see NOTE below).

3. P1 Protocol: set to BACNET (Default Setting).

4. P1 Manual MAC Address: set to 1
(Default Setting).

5. P1 Baud rate: set as required by network.
If not known, set to AUTO.

6. P1 Parity: set to NONE (Default Setting).

Using Communications Protocol

TB3 Port 1 Native BAS RS-485.

SW1 RS-485 Biasing Switch for Port. Set to ON if

chiller is in an End of Line position on the network.

U26 is the Port 1 RS-485 Driver Chip. It is sock­eted to allow field replacement. RX1 and TX1 LEDs
illuminate to indicate Port 1 communications activity.

QTC4 Native Communication Setup

Native communication is applicable to three types of
protocols, they are BACnet, N2 and Modbus RTU.
It requires IPU II Microboard (331-03478-101) and
software version Y.ACS.20.02 or later.

BACnet MS/TP Setup Port 1 (TB3)

To setup the BACNET MS/TP Port 1, follow the steps
below:

1. Connect the BACnet MS/TP Network to Port 1 on
the IPU II I/O Board.

2. Set up the QTC4 Port 1 (P1) for BACnet
Communications as shown in Figure 18 on Page

99.

7. P1 Stop Bits: set to 1 (Default Setting).

The BACnet DE Instance (Device Instance) is
determined by adding the [DE MODIFIER AD­DRESS x 100] with the DE MODIFIER OFFSET. For
example, if the desired DE Instance address is 5023,
set the DE Modifier Address to 50, and then set the
DE Modifier Offset to 23 (50 X 100 + 23 = 5023).
DE Instances must be limited to values between
1 and 4,194,303 and every device in the network must
have a unique device Instance.

N2 Metasys Setup Port 1 (TB3)

1. Connect the N2 Network to Port 1 on the IPU II
I/O Board as shown in Figure 18 on Page 99.

2. Set up the QTC4 Port 1 (P1) for N2 Communica­tions.

To access the Communication parameters:

You must always cycle power to the
microboard following port setting
changes.
