interiors of all framework and panels are covered with 1/2"
thick, 1½ lb. dual-density berglass insulation. Closed-cell
foam (IAQ) insulation is available as a selectable option, suit­able for berglass-free applications. Multiple 1" lters are
supported by factory-mounted brackets for side removal in
either direction.

Electrical components are located in the lower section,
adjacent to the compressor(s). Knockouts are provided on
both sides of the unit to facilitate main power and low voltage
wiring through separate holes. Each unit is rated to accept time
delay fuses for branch circuit overcurrent protection. Each unit
is listed with CETL and CE.

The control box is accessible through the compressor sec­tion access panel. The control box houses the major operat­ing electrical controls, including the control circuit board(s),
transformer, compressor contactor(s), fan contactor(s) and

Figure 1: Front View with Access Panel Removed

The reversing valve is energized in the heating mode
and will “fail-safe” to the cooling mode, which is the pre­dominant mode of operation.

Both heat exchanger components incorporate advanced-

heat transfer technologies. The coaxial heat exhanger has a
copper inner tube and steel outer tube. The large face area
coil has copper tubes and aluminum ns. Geothermal units

include coil and piping insulation to protect against conden-

sation in low temperature applications.

Safety controls on each refrigerant circuit include a suc-

tion line temperature sensor, low refrigerant pressure and
high pressure switches to lock out compressor operation at
extreme conditions. The safety controls can only be reset
from the main disconnect switch to prevent unauthorized
reset. Each circuit has high and low side refrigerant service
valves for refrigerant circuit diagnostics and charging.

Thermal Expansion Valve

Units include a Thermal Expansion Valve (TXV) for

refrigerant metering. The TXV allows the unit to operate at
optimum efciency with uid temperatures ranging from
25°F to 110°F, and entering air temperatures ranging from
40°F to 90°F. The TXV precisely meters the exact amount
of refrigerant ow through the system to meet the load and
deliver rated heating and cooling capacity.

Fan Section

The fan section includes a belt-driven fan assembly,
multiple DWDI forward curved fan wheels, solid fan shaft,
steel ball bearings, three phase fan motor, adjustable motor
sheave, adjustable motor base, fan pulley and insulated
divider panel between the compressor section. Unit sizes
072 through 120 have two fan assemblies and unit sizes
180 through 290 have three fan assemblies. The fan motor
is always located at the piping end, but may be relocated to
the opposite side in the eld.

Control Features – MicroTech® III Controller

The MicroTech III Controller is a microprocessor-based
control board conveniently located in the unit control box for
easy access through a removable access panel. The standalone
unit controller is a hard wired interface and provides all the
necessary eld connections. The board can be wired for 24­volt AC output to the wall thermostat by using terminals R
& C. An LED annunciator is located on the front of the unit
chassis to allow quick check of the unit operating status.

MicroTech III Operating Features

Assumes cycle fan operation-not continuous fan operation:

■ Start-up – The unit will not operate until all the inputs

and safety controls are checked for normal conditions.

■ Cooling mode – On a call for cooling from the wall ther-

mostat, the controller will energize the fan relay and stage
compressors to satisfy the space temperature setpoint.
When the load is satised, the controller will disable the
compressor and fan.

■ Heating Mode – On a call for heating from the wall

thermostat, the controller will enable the fan, energize

circuit one reversing valve and circuit 1 compressor to

satisfy the space heating setpoint. If the space temperature
setpoint is not satiseld, circuit two reversing valve and
circuit 2 compressor will be energized and run until the
heating setpoint at the thermostat is satised.

■ Random Start Power-up Delay Timer – In the event of

a building power outage, this feature prevents multiple
units from starting simultaneously upon building power
restoration.

■ Unoccupied Mode – A simple “grounded” signal between

terminals U and C (no power source required), puts the
unit into the unoccupied mode for night setback operation.

■ Interstaging Timer – A default value of 5 minutes be-

tween staging of compressors, this feature minimizes short
cycling of compressors and improves comfort.

■ Override Mode – A switch on the deluxe automatic

changeover thermostat can be activated during the unoc­cupied mode to put the unit back into the occupied mode
for two hours for after-hours heating or cooling.

■ Motorized Valve/Pump Restart – The IV/PR (H8) ter-

minals on the The MicroTech III unit controller are used

to energize (open) a motorized valve or start a water pump
to get water circulating prior to starting the compressor on
call for heating or cooling. The IV/PR (H8) terminal may
be “daisy chained” between a maximum of 200 units.

■ Brownout Protection – The MicroTech III unit controller

measures the input voltage and will suspend compres­sor and fan operation if the voltage falls below 80% of

the unit nameplate rated value. A unique LED status is

generated.

■ Unit Shutdown – A simple grounded signal puts the unit

into the shutdown mode. Compressor and fan operations
are suspended. A unique LED status is generated.

■ Condensate Overow Protection – The

MicroTech III

controller incorporates a liquid sensor at the top of the

drain pan. Upon sensing water ow, cooling operation is
suspended. A unique LED status is generated.

■ Remote Reset of Automatic Lockouts – The Remote

Reset feature provides the means to remotely reset auto-

matic lockouts generated by high-pressure and/or low­temperature faults. When the MicroTech III controller is
in automatic lockout due to one of these faults, and the
cause of the fault condition has been alleviated, energiz­ing the O-terminal for 10 seconds or more will force the
control board to clear the lockout. A unit power cycle can
also be used to clear an automatic lockout if the conditions
causing the fault have been alleviated.

■ Intelligent Reset – The Fault Retry feature helps to

minimize nuisance trips of automatic lockouts caused by
high-pressure and/or low-temperature faults. This feature
clears faults the rst two times they occur within a 24-hour
period and triggers an automatic lockout on the 3rd fault.
The retry count is reset to zero every 24 hours.

■ Equipment Protection Control – The MicroTech III

controller receives separate input signals from the refrig-

erant high-pressure switch and the low suction line tem­perature sensor. In a high-pressure situation, compressor
operation is suspended. In a low temperature situation,
the unit goes into a defrost cycle where the unit is put
into cooling operation for 60 seconds until the coaxial
heat exchanger is free of ice. Each switch generates its
own unique LED status.

Note: Most unit fault conditions are the result of operating

the equipment outside the unit specications.

Large Vertical Water Source Heat Pump units are easily

located in equipment rooms or oor-by-oor installations.

They can be applied to all building types where it is
advantageous to extend the water source heat pump concept
to larger or core areas.

Locate the unit in an area that allows for easy removal
of the lter and access panels, and has enough space for
service personnel to perform maintenance or repair. Provide
sufcient room to make water, electrical and duct connections.

Figure 4: Service Clearances

Applications

The main control panel is located in the center front of

the unit. The fan discharge is top front, and the fan motor
is always located at the piping end. Unit sides opposite
the control panel and opposite the piping side may be up
against walls and still allow for service and maintenance
through the remaining access panels.

Figure 5: Fan Deck Arrangements

The contractor should make sure that access has been
provided including clearance for 2" (51 mm) thick lter
brackets, duct collars and ttings at water and electrical
connections. Allow adequate room around the unit for a
condensate trap. The unit can be installed “free standing”
in an equipment room. Generally, the unit is located in a
separate room with the non-ducted return air facing the
return air intake.

Alternatively, the unit can have a ducted return air. It is
recommended that the unit be located on vibration isolators
to reduce any vibration (see Figure 6, page 12).

IMPORTANT

1. A 24" (610 mm) minimum clearance is required on the
return air, control box and piping sides. However, a 36"
(914 mm) clearance allows for easier serviceability.

2. A 12" (305 mm) minimum clearance is required on Side
A to gain access to panel to remove locking collar for shaft
removal.

3. A 6" (152 mm) clearance is required on Side B to remove
screws holding top panel.

4. Top clearance is required for fan shaft removal.

5. Some codes dictate a 60" (1524 mm) clearance above
the control box which could be violated with a ducted

return. Check your local codes.

“front” of the unit, the water piping connections may be
right-hand (side) or left-hand. All units have a single supply
and return water connection with a copper FPT type tting
that protrudes through the unit casing for easy connection.

The condensate connection is also a copper FPT type and is

located on both sides of the unit. The unused connection is
plugged.

Notes:

1. The hand of unit is determined by looking at the return air
(lter) side. The piping and electrical connections are always
made on the “hand” side of the unit. The return air (lter) side is
considered the “front” of the unit.

2. The fan motor is always located at the piping/electrical
connection (hand) side of the unit.

Applications

Vibration Isolators

Figure 6: Vibration Isolator Dimensions

For minimum sound and vibration transmission, it is recom­mended that the unit be mounted on vibration isolators.

Holes are provided in the bottom panel to facilitate con-

nection of isolators (see Figures 7-8 for hole locations).

Isolators supplied by the manufacturer are the type

shown in Figures 6. Four white isolators are used for single

compressor units and six green isolators are used for dual

compressor units. The holes in the bottom of the unit allow
for a 3⁄8" (10 mm) bolt to be secured to the isolator.

Ductwork and Attenuation

Discharge ductwork is normally used with these condi­tioners. Return air ductwork may also be required but will
require eld installation of a return air duct collar.

All ductwork should conform to industry standards of
good practice as described in ASHRAE Systems Guide.

The discharge duct system will normally consist of a
exible connector, a transition piece to the nal duct size, a
short run of duct, an elbow without vanes and a trunk duct
tee’d into branch ducts with discharge diffusers. Transfor-

mation duct must not have angles totalling more than 30

degrees or severe loss of air performance can result.

All units have multiple fan outlets. The preferred
method for minimum static pressure loss would be indi-

vidual ducts at each outlet connected to a larger main duct

downstream (Figure 9).

Figure 9: Suggested Supply Ducting per ASHRAE and SMACNA Publications

For minimum noise transmission, the metal duct mate­rial should be internally lined with acoustic brous insula­tion. The ductwork should be laid out so that there is no
line of sight between the conditioner discharge and the
distribution diffusers.

Return air ducts can be brought in adjacent to the return
air of the conditioner. Typically, the equipment room be­comes the common return air plenum.

Do not insert sheetmetal screws directly into the unit
cabinet for connection of supply or return air ductwork,
especially return air ductwork which can hit the drain pan
or the air coil.

Notes:

1. Transformations to supply duct have maximum slope of 1" to 7".

2. Square elbows with double thickness vanes may be substituted.

3. Do not install ducts so that the air ow is counter to fan rotation.

If necessary, turn fan deck assembly and motor.

4. Transformations and units shall be adequately supported so no

weight is on the exible connection.

Typical Cooling and Heating Refrigeration Cycles – Dual Compressors

Note: Typical temperature readings are at full load conditions at ISO-13256 for boiler-tower applications.

Figure 10: Cooling Refrigeration Cycle

When the wall thermostat calls for COOLING, the revers­ing valve (de-energized) directs the ow of the refrigerant,
a hot gas, from the compressor to the water-to-refrigerant
heat exchanger (coaxial heat exchanger). There, the heat is
removed by the water, and the hot gas condenses to become
a liquid. The liquid then ows through a thermal expansion
valve to the air-to-refrigerant heat exchanger coil (evapora­tor). The liquid then evaporates and becomes a gas, at the
same time absorbing heat and cooling the air passing over the
surfaces of the coil. The refrigerant then ows as a low pres­sure gas through the reversing valve and back to the suction
side of the compressor to complete the cycle.

Figure 11: Heating Refrigeration Cycle

When the wall thermostat calls for HEATING, the
reversing valve (energized) directs the ow of the refriger­ant, a hot gas, from the compressor to the air-to-refrigerant
heat exchanger coil (condenser). There, the heat is removed
by the air passing over the surfaces of the coil and the hot
gas condenses and becomes a liquid. The liquid then ows
through a thermal expansion valve to the water-to-refrigerant
heat exchanger (evaporator). The liquid then evaporates and
becomes a gas, at the same time absorbing heat and cooling
the water. The refrigerant then ows as a low pressure gas
through the reversing valve and back to the suction side of
the compressor to complete the cycle.

Applications – Systems

Water source heat pump systems are one of the most ef-

cient, environmentally friendly systems available for heating
and cooling buildings. High-efciency, self contained units
(sizes 7,000 btuh to 290,000 btuh) can be placed in virtually
any location within a building. Each unit responds only to
the heating or cooling load of the individual zone it serves.
This permits an excellent comfort level for occupants, better
control of energy use for building owners and lower seasonal
operating costs. The Air-Conditioning Refrigeration Institute
(ARI) and the International Standards Organization (ISO)
publish standards so that water source heat pumps are rated
for specic applications. The ARI/ISO loop options shown in
this catalog are typical water source heat pump loop choices
available in today’s market. These systems offer benets rang­ing from low cost installation to the highest energy efciency
available in the market today.

Boiler / Tower Applications: ARI 320 / ISO
13256-1

A “Boiler/Tower” application uses a simple two-pipe
water circulating system that adds heat, removes heat or
transfers rejected heat to other units throughout the build­ing. The water temperature for heating is generally main­tained between 65ºF – 70ºF and is usually provided by a
natural gas or electric boiler located in a mechanical room.
The condensing water temperature, during cooling months,
is maintained between 85ºF and 95ºF and requires the use
of a cooling tower to dissipate waste heat. Cooling tow­ers can be located on the roof, or inside or adjacent to the
building. This application can be the lowest cost of the loop
options available.
Note: ASHRAE 90.1 standards require that circulating
pumps over 10 HP will require use of “variable frequency
drive” equipment and pipe insulation to be used whenever
water temperatures are below 60 degrees and above 105
degrees. See ASHRAE 90.1 Standards for details.

Open Loop Well Water Applications: ARI
325 / ISO 13256-1

“Open Loop” well water systems use ground water
to remove or add heat to the interior water loop. The
key benet of an open loop system is the constant water
temperature, usually 50ºF to 60ºF, which provides efcient
operation at a low rst cost. Most commercial designers
incorporate a heat exchanger to isolate the building loop
from the well water. Using heat exchangers can reduce
maintenance issues while still allowing the transfer of heat
from unit to unit as with the “Boiler/Tower System”. A suc­cessful design provides an ample amount of groundwater
(approximately 2 GPM per ton) and adequate provisions
for discharging water back to the aquifer or surface. Open

Loop applications are commonly used in coastal areas

where soil characteristics allow reinjection wells to return
the water back to the aquifer. Note that some states have re­quirements on the depths of return water reinjection wells,
and such wells must be approved by the United States En­vironmental Protection Agency. Also, bad water quality can
increase problems with heat exchanger scaling. Suspended
solids can erode the heat exchanger. Strainers can be used
to contain suspended solids.

Closed Loop Geothermal Applications ARI
330/ISO 13256-1

“Vertical Closed Loop” applications are installed by
drilling vertical bore holes into the earth and inserting
a plastic polyethylene supply/return pipe into the holes.
The vertical wells are connected in parallel reverse return
fashion to allow the water from the building to circulate
evenly throughout the boreeld. The circulating uid dis­sipates heat to the ground in a similar manner as a “tower”
and adds heat back to the loop like a boiler. If properly
designed, the loop eld can maintain the loop temperatures
necessary to condition the building without the use of a
boiler or a tower. Loop temperatures usually range from
37ºF to 95ºF in Northern climates. Southern applications
can see temperatures ranging from 40ºF to 100ºF. The
number of bore holes and their depth should be determined
by using commercial software that is specically designed
for vertical geothermal applications. Typical bore depths
of a vertical loop range from 150 to 400 feet and generally
require about 250 feet of surface area per ton of cooling.

Figure 14: Vertical Loop Application

Figure 15: Horizontal Loop Application

A “Surface Water” or “Lake” closed loop system is a

geothermal loop that is directly installed in a lake or body
of water that is near the building. In many cases, the body
of water is constructed on the building site to meet drainage
or aesthetic requirements. Surface loops use bundled

polyethylene

as a vertical or horizontal loop using a parallel reverse
return design. The size and the depth of the lake is critical.
Commercial design services should be used to certify that a
given body of water is sufcient to withstand the building
loads. Loop temperatures usually range from 35ºF to 90ºF
and prove to be the best cooling performer and lowest
cost loop option of the three geothermal loops. Some
applications may not be good candidates due to public
access or debris problems from ooding.

coils that are connected in the same manner

Figure 16: Surface Water Loop Application

A closed loop “Horizontal” geothermal application

is similar to a vertical loop application with the exception

that the loops are installed in trenches approximately 5

feet below the ground surface. The piping may be installed
using a “four-pipe” or “six-pipe” design and could require
1,500 to 2,000 square feet of surface area per ton of
cooling. Loop temperatures for a commercial application
can range from 35ºF to 95ºF in Northern climates. Southern
climates can see temperatures ranging from 40ºF to
100ºF. Horizontal loops are generally not applied in urban
areas because land use and costs can be prohibitive. New

advances

Environment

This equipment is designed for indoor installation only.
Sheltered locations such as attics, garages, etc., generally
will not provide sufcient protection against extremes in
temperature and/or humidity, and equipment performance,
reliability, and service life may be adversely affected.

Power supply

A voltage variation of +/-10% of nameplate voltage is
acceptable. Three-phase system imbalance shall not exceed
2%.

Additional information for initial
start-up only

Standard range units:

Units are designed to start in an ambient of 50ºF (10ºC),
with entering air at 50ºF (10ºC), with entering water at 70ºF
(21ºC), with both air and water at the ow rates used in the
ISO 13256-1 rating test, for initial start-up in winter.

Note: This is not a normal or continuous operating

condition. It is assumed that such a start-up is for the
purpose of bringing the building space up to occupancy

temperature.

Combination Balancing and Shutoff (Ball)
Valves

Constructed of brass and rated at 400 psig (2758 kPa)
maximum working pressure. Valves have a built-in adjust­able memory stop to eliminate rebalancing. Valves have
FPT connections on both ends for connection to the water
hose and to the eld piping.

Figure 34: Shut off Ball Valve

Motorized Valve

Used in variable pumping type applications, the valve
actuator is wired and typically piped in the return water
line. On a call for heating or cooling, the valve will open
prior to the compressor starting. The 24VAC valve actuator

must be wired directly to terminal block H8 on the
MicroTech III controller. The valve is rated for 300

psig (2070 kPa).

Multiple Unit Control Panel (MUCP)

Figure 36: Multiple Unit Control Panel and Board

The Multiple Unit Control Panel (MUCP) is an acces-

sory used when up to 3-units are controlled from a single
thermostat. The MUCP must be eld-installed in a remote
location, typically close to the units and convenient for
service access.

A maximum of 2 boards may be used together if up to
6-units must be connected and controlled from a single
thermostat.

Figure 37: Multiple Unit Control Panel Ciruit Board

Field Installed Controls

 The 2-way motorized water valve kit includes the valve

body, actuator and wire harness. The valve will only open
on a call for heating or cooling. The valve is rated for 300
psig (2070 kPa).

 A multiple unit control panel allows a single thermostat

to control up to three units in parallel.

The multiple unit control board provides the compo-

nents necessary to protect the MicroTech III unit controller

from electrical damage that may occur when using standard
