Features and Benefits
Efficiency
WHR-EW Water-Cooled and WHR-EA Air-Cooled, (depending on remote condenser selection) meet
ASHRAE 90-1 efficiency levels - the world’s standard for chiller efficiency.
The “E” vintage WHR-EA reciprocating chillers offer some of the highest operating efficiencies
available today through the use of highly efficient components and efficiency oriented packaging.
Operating economy at reduced load is increased by operating each refrigerant circuit partially
unloaded, rather than one circuit off and the other circuit fully loaded. At unloaded conditions each
compressor will operate at lower compression ratios with substantial power savings.
Optional steps of capacity reduction are accomplished by the most efficient method of cylinder
unloading in the industry today.
To McQuay, operating economy means more than just energy efficiency. The WHR chillers reduce
operating costs not only through energy efficiency, but by offering high unit reliability, easy
serviceability, full factory testing and the backing of a factory trained sales, service and parts
organization.
Flexibility
The WHR chillers come in 25 sizes between 17 and 210 nominal tons (60 and 710 kW). The small
capacity increments provide a selection that will closely match the required job capacity.
The WHR water chillers come completely factory assembled, piped, wired, and shipped in one piece;
ready for water piping and wiring connections. The EA remote condenser models are ready for field
piping to the remote condenser. Single main supply power terminal block can be supplied by one field
installed main supply power disconnect switch.
Many optional features can been added to fit your needs. A unit mounted non-fused disconnect
switch eliminates the need for a field installed disconnect. Phase failure/reversal protection, high
return water unloading, and acoustical sound enclosures around compressor are all optional features
that can be factory installed.
Reliability
The McQuay WHR chillers use the most advanced and efficient reciprocating compressors in the
industry, the Copeland DISCUS valve compressors. These heavy-duty, industrial quality, semihermetic compressors are designed for R 22 or R-134a.
All WHR chillers are factory run tested to assure unit functionality. All safety and operating controls
are checked and calibrated. Chillers for remote condensers are connected to slave condensers for
testing purposes. This extensive testing assures trouble-free start-ups.
To protect the unit from abnormal operating conditions, a complete set of safety controls for each
circuit is used. Safety controls include compressor crankcase heater(s), freeze protection
pressurestats (manual reset), oil switches (manual rest), high pressure safety switches (manual reset),
and compressor motor overload protectors. Standard operating controls include time delay relays for
20-second sequence starting of compressors, manual pumpdown switches, low pressure controls,
compressor lead-lag switches (WHR-040EW-210EW) and chilled water temperature controller. All
controls and wiring are completely factory labeled for ease of service.

Page 5
Serviceability
Semi-hermetic, 1750 rpm induction type motors are employed. The motors are refrigerant gas cooled.
A finned motor housing helps dissipate motor heat. Solid-state modules in the motor terminal box
respond to temperature sensors imbedded in all three motor windings to provide inherent thermal
overload protection for all run and start conditions.
Serviceable compressors offer reduced
maintenance costs because if problems
develop with components such as oil
pumps, unloaders, and pistons, they
can be serviced in the field without
replacing the compressor. Both suction
and discharge service valves are
provided to allow isolation of the
compressor from the refrigerant circuit.
All multiple compressor units utilize
two independent refrigerant circuits.
Dual refrigerant circuits permit
shutdown and routine maintenance and
service of one circuit while the second
circuit maintains system operation
where two or more compressors are
supplied.
Refrigerants
Models WHR 017 through WHR 210 utilize R-22 as the standard refrigerant. Models WHR 040
through WHR 210 can be furnished with R-134a refrigerant.
Full factory testing
Extensive quality control checks and individual performance tests assure that the units will meet the
requirements of the application and start-up and perform reliably. EA remote condenser models are
shipped with a holding charge of refrigerant, EW water-cooled units are shipped with a complete
operating charge.
Each unit is pressure tested, evacuated and charged with refrigerant for test purposes. Extensive
quality control checks and individual unit performance tests, at full load, ensure that each control is
properly adjusted and operates correctly. EA remote condenser models are connected to factory slave
condensers for testing. Each unit is then rechecked for refrigerant leakage.
Code Approvals
All WHRhb units are constructed and/or rated with the latest ANSI/ASHRAE 15 Safety Code,
National Electrical Code and ASME Boiler and Pressure Vessel Code. All models are ETL approved or
cETL listed.

Design Advantages
Unit Arrangements
The McQuay water chillers are completely factory assembled, piped, wired and shipped in one piece,
ready for field connection of refrigerant (EA models) and water piping. Each unit consists of motor
compressors, insulated DX cooler and centralized electrical control panel containing all necessary
safety and operating controls, and compressor starting controls. Arrangement “EW” units come
complete with water-cooled condensers with integral subcooler circuits. Arrangement “EA” units are
provided without condensers to allow for remote installation of air-cooled or evaporative condensing
equipment.
Compressors
WHR chillers use Copeland DISCUS semi-hermetic compressors. These compressors are designed
for R 22 and R-134a.
Semi-hermetic, 1750 rpm induction type motors are used. The motors are refrigerant gas cooled. Solidstate modules in the motor terminal box respond to temperature sensors imbedded in all three motor
windings, providing inherent thermal overload protection for all run and start conditions.
The compressor housing is constructed from close grained, high nickel content, alloy cast-iron with
no bolted joint between the motor and compressor. The housing includes a cast-iron cylinder head
and stator cover, and a crankcase oil sightglass. A suction strainer built into the compressor in the gas
stream between the suction service valve and the motor, filters out foreign and abrasive particles. An
internal relief valve relieves discharge pressure to the suction side for safety protection at high
compression ratios as required by ANSI/ASHRAE 15 Safety Code.
Main bearings are solid cast bronze insert type with oversized bearing area resulting in ultra-low
bearing loading.
The crankshaft is die-forged, high strength iron alloy with integral counterweights, statically and
dynamically balanced for smooth operation.
Connecting rods are lightweight aluminum with integral bearing surfaces on the crankshaft and piston
ends. Pistons are close grain cast iron with oil and compression rings. Piston pins are full floating
type for long life.
Compressors have a forced-feed lubrication system with positive oil displacement, a reversible oil
pump, and an operating oil charge. The pump feeds oil through rifle-drilled passages in the crankshaft
to all bearing surfaces. Magnetic plugs trap particles that enter the crankcase. The oil supply filters
through a large area oil strainer. During start-up, a crankcase heater minimizes oil being diluted by
refrigerant.
Factory Installed Liquid Line Components
Each refrigerant circuit has a filter-drier, liquid line sightglass/moisture indicator, solenoid valve,
manual liquid line shutoff valve and thermal expansion valve.
Short Circuit Protection
(WHR 017 through 030, WHR 095 through 210)
Each compressor is individually protected against short circuit and locked rotor conditions by factory
installed circuit breakers. Separate fusing protects the control circuit. WHR-040 through 090 can have
circuit breakers factory installed as an option.

Part Load Efficiencies
Part load efficiencies and Integrated Part Load Values (IPLV) for EW units are calculated according to
the requirements of the latest ARI Standard 550/590-98 and meet or exceed ASHRAE Efficiency
Standard 90.1. Since most air conditioning systems operate at less than design full load a majority of
the time, IPLV is an excellent method for comparing chillers' efficiencies.
Noise
All McQuay WHR chillers are equipped with hot gas discharge line mufflers in each refrigerant circuit
to reduce the overall sound levels. An optional insulated acoustical compressor enclosure to further
reduce sound levels is also available for most units. Sound level ratings are contained in the Sound
Rating section of this manual.
Unit Base
Designed for easy handling, the units are mounted on a compact, rugged formed steel base. Isolator
mounting holes are provided.
Electrical Control Center
Shipped with all operating and safety controls and motor starting equipment factory wired,
operationally tested, and ready for operation. All controls are centrally located in a hinged control
center with keylocked doors.
Part-winding starters are standard on 208/230 volt applications and available as a special on 460/575
volts. Across-the-line starters are standard on 380/460/575 volts.
A five-minute, solid-state lockout timer is provided to delay compressor restart after safety cutout or
power interruption, or under irregular cooling load demands. A lead lag switch is standard on all units
(WHR 040 – WHR 210) not incorporating the single circuit hot gas bypass option.
Evaporator
The evaporator is a direct expansion, shell-and-tube type with water flowing in the baffled shell side
and refrigerant flowing through the tubes.
The evaporator is constructed with a carbon steel shell and seamless high efficiency copper tubes,
roller expanded into heavy carbon steel tube sheets. Water baffles are polypropylene to resist
corrosion.
Refrigerant heads are carbon steel with multi-pass baffles to ensure oil return and are removable to
permit access to the tubes from either end. For water removal, 3/8" (10mm) vent and drain plugs are
provided on the top and bottom of the shell. Two 1/2” (12.7mm) couplings on each water nozzle allow
for easy field installation of sensor equipment.
The evaporator is wrapped with 3/4” (19.1mm) thick vinyl nitrate polymer sheet insulation. The
insulation has a K factor of 0.28 at 75°F (24°C). The insulation is fitted and cemented in place, then
painted with a resilient vinyl base paint to resist cracking.
The tube side maximum working pressure is 225 psig (1552kPa). The waterside working pressure is 175
psig (1206kPa). All evaporators are designed, constructed, inspected and stamped according to the
requirements of the ASME Boiler and Pressure Vessel Code.
Product Manual WHR-2 7

water controller, 1a) the same controller but with an indicator light package, and 2) the MicroTech
Controller.
Standard Control
WHR-017 - 030
A return water electromechanical temperature controller is supplied on the WHR-17 through 030
when supplied with two stages. Three stage units are supplied with a solid state, return water
temperature controller.
On Model EA units for remote condensers this controller is equipped with terminals from which the
first fan motor can be energized on compressor start. These sizes have a single refrigerant circuit.
WHR 040 - 210
The UNT-33 microprocessor leaving water temperature controller is standard on all units from size
040 to 210 and provides precise temperature control based on leaving water temperature. The
control is preset and calibrated and no other adjustment is required other than setpoint. There is a
60 second interstage On Delay between stages. Each stage incorporates minimum on and off timers
with a maximum cycle rate of six cycles per hour. Reset of supply water temperature can be
accomplished from outside air temperature, zone temperature or a signal from an EMS system.
Condenser fan control (Model EA)
Some means of controlling discharge pressure is required on condensers applied to the WHR-EA
remote condenser units. The McQuay AC/AQ air-cooled condensers can be equipped with
pressure activated fan cycling switches or with variable speed drives. Neither method requires
interconnecting wiring between the chiller and condenser.

Optional MicroTech Chiller Controller
WHR-040 – 210 Only
The MicroTech reciprocating chiller controller surpasses all other microprocessor-based chiller
control systems available today. This powerful, user-friendly control system provides the flexibility
and performance needed for a stand-alone unit as well as multiple units tied into a network system.
MicroTech’s state-of-the-art design will not only permit your chiller to run more efficiently, but will
also simplify troubleshooting if a system failure occurs. Every MicroTech controller is programmed
and tested prior to shipment to ensure a trouble-free start-up.
Condenser fan control (Model EA)

condenser fans or groups of fans based on discharge pressure. Field wiring is required between
the chiller and the remote condenser.
10 Product Manual WHR-2
Page 11
Operator-friendly
The 12-key, touch-sensitive, membrane keypad and 32-character display makes the MicroTech
system especially user-friendly. Inch-pound or SI units are optionally available.
The MicroTech menu structure is separated into three distinct categories, which provide the
operator or service technician with a full description of current unit status, control parameters, and
alarms. Security protection prevents unauthorized changing of the setpoints and control
parameters.
MicroTech continuously performs self-diagnostic checks, monitoring all system temperatures,
pressures and safeties, and will automatically shutdown a compressor, a refrigerant circuit of the
entire unit should a fault occur. The cause of the shutdown will be retained in memory and can be
easily displayed in plain English or metric units for operator review. The MicroTech chiller
controller can also retain and display the time the fault occurred and the operating conditions that
were present at the time of the fault, which is an extremely useful feature for troubleshooting. In
addition to displaying alarm diagnostics, the MicroTech chiller controller also provides the operator
with a warning of pre-alarm conditions.
Ice storage
The MicroTech control easily changes the leaving fluid setpoint via a remote signal to the
controller. The feature enables selection of chilled water or ice storage mode.
Enhanced chiller operating efficiencies
The MicroTech chiller controller offers many features to improve the operating efficiency of the
reciprocating chiller. In addition to monitoring water temperature and air temperatures, refrigerant
temperatures and pressures, and unit amperage, MicroTech also offers the following energy saving
features:
Programmable setpoints
The MicroTech chiller controller offers precise digital settings of the leaving chilled water
temperature setpoint and all other control parameters. This is extremely important in the setting of
safeties such as low leaving water temperature cutout, high pressure cutout, suction pressure
cutout, and freeze protection.
Compressor soft loading
Soft loading limits the number of cooling stages to prevent unnecessary electrical demand and
possible overshoot of the leaving chilled water temperature setpoint.
Demand limit control
Based on a 4-20mA DC signal, the controller will determine the maximum number of stages permitted
to operate, preventing additional demand charges during high usage periods.
Product Manual WHR-2 11
Page 12
Automatic circuit lead-lag
With the keypad, the operator can manually select either refrigerant circuit for the lead position or
the controller will automatically select the lead circuit based on the circuit with the fewest operating
hours.
Time clock, daily and holiday start/stop control
The operator can program daily start/stop schedules including weekends and up to fourteen
separate holidays without the need of an external time clock or EMS interface. If desired, an
external time clock can be used instead of the internal schedule.
Chilled water pump control
There is no need for an external time clock or EMS interface to control the pump start/stop
operation. The MicroTech chiller controller can accomplish this through a digital output. If an
alarm shuts down the chiller, the chilled water pump will remain on, providing any remaining cooling
to the loads.
Optional Network Master Panel
The MicroTech Network Master Panel (NMP) allows multiple reciprocating chiller controllers to be
incorporated into a building-wide network with other MicroTech units and auxiliary controllers. In
conjunction with a personal computer, it provides the building operator with the capability to
perform advanced equipment control and monitoring from a central or remote location. The
following features are provided by the optional NMP:
• Remote unit monitoring
• Advanced scheduling features
• Advanced alarm management features
• Global operator override
• Global unit shutdown input
• Demand metering
• Historical electrical data logging
Optional Remote Monitoring and Sequence Panel
One to three reciprocating chiller controllers can be incorporated into a network with the MicroTech
remote monitoring and sequencing (RMS) panel. The optional RMS panel provides the following
features:
• Remote chiller monitoring (up to 3)
• Automatic or manual chiller sequencing
• Automatic or manual lead-lag designation
• Common chiller scheduling
• Optimal start control
• Chilled water reset by outdoor air temperature or external 4-20 mA signal
• Chiller run time totalization by month, current year, and prior year
• Cooling degree-day totalization by month, current year, and prior year
The RMS panel is equipped with a keypad/display that is identical to the chiller controller’s
keypad/display. With a special keystroke combination, the RMS keypad/display can be interfaced
with any chiller controller. It then operates identical to the chiller-mounted keypad/display. Thus
the operator has full access to all networked chillers from a single remote location. Panel-mounted
LED’s clearly indicate which controller the RMS panel keypad/display is currently interfaced with.
12 Product Manual WHR-2
Page 13
Monitor software
When properly equipped with MicroTech Monitor software, a direct or remote connected PC can be
used for monitoring unit operation, changing setpoints, scheduling, trend logging, downloading
controller software, and diagnostics. For MicroTech network systems, the PC gives the operator
access to all unit and auxiliary controllers in the network. Specific controller or global data can be
displayed as desired. All keypad status information and control capability is available at the PC in a
full-screen format. Many additional unit control parameters, which are not available at the unit
controller’s keypad, are also available. Monitor software provides the following features:
• High resolution, unit-specific graphic representations
• One-touch function keys
• Multiple unit display screen
• Automatic screen refresher

Open Protocol
MicroTech Open Protocol Master panel provides an interface between MicroTech unit controllers
and virtually all building automation systems (BAS). A protocol is a set of rules governing data
exchange between microprocessors, thereby permitting communications between unlike controllers.
As a result, building designers, owners and operators can obtain the advantages of McQuay
equipment, and the control versatility MicroTech has to offer. A low cost site license covering any
and all McQuay product is required.
MicroTech BACdrop Gateway
The McQuay BACdrop Gateway panel allows any BACnet based building automation system
(BAS) to communicate with MicroTech controllers. The panel translates between the standard
BACnet protocol (ANSI/ASHRAE 135-1995) and the MicroTech protocol. No modifications to the
MicroTech hardware or software are necessary. Since BACnet is a standard, public protocol no
license agreement is necessary.

then be used to select any condenser from its own capacity data. For a McQuay AC/AQ air-cooled
condenser, use product manual PM ACAQ.
1. Ratings may be interpolated for any chiller water temperature between 42°F and 50°F but
cannot be extrapolated (contact factory for ratings outside this range).
2. Chilled water quantities - Ratings are based on a 10 degree F chilled water range and are
applicable from a minimum of 6 degrees F to a maximum of 16 degrees F differential between
entering and leaving chilled water temperatures.
3. Ratings are based on .00025 fouling factor for both condenser and evaporator. For other
fouling factors, multiply ratings by cooler factors from Table 3 and Table 4. For applications
using a glycol solution, see Table 1 and Table 2.
Selection Procedure
Normally the required chiller capacity in tons, the entering and leaving chilled water temperature
and flow and the design outdoor air temperature are known. Determine any unknown quantity
using the formula:
Tons = gpm x delta T / 24
Capacity data is in Table 12 and Table 13 for IP units and Table 14 and Table 15 for SI units. Rating
are based on:
• Leaving chilled water temperatures from 42°F to 50°F (6°C to 10°C) with a 10 degree delta-T.
Selections can be interpolated between these leaving temperatures but not extrapolated.
Product Manual WHR-2 15
Page 16
Correction factors for delta-Ts other than 10 degrees are in Table 3 and Table 4. Exceeding the
Delta-T range of 6 to 16 degrees will cause problems controlling unit unloading.
• Condensing temperatures (CT) from 105°F to 125°F (40°C to 55°C).
• Total Heat Rejection (THR) is given and used to select the condenser, whether it be a dry air-
cooled condenser or an evaporative condenser.
Several different size condensers can usually be matched to any given WHR-EA unit depending on
the condensing temperature that typically ranges from 20 to 30 degrees F above the design outdoor
temperature. Increasing condensing temperatures will reduce the chiller capacity, increase its power
consumption and result in a smaller condenser being required.
Normally a WHR-EA is selected to meet or exceed the required cooling capacity at some
condensing temperature and a condenser then selected with sufficient capacity to handle the heat
rejection with the selected temperature difference (TD, difference between design outdoor dry bulb
temperature and condensing temperature).
A more accurate solution can be achieved by plotting the capacity of the chiller and the condenser
as a function of the TD and observing the curves intersection that is the system balance point. An
example is shown in the following "Selection Example" section.
Sample Selections
Given: Required capacity of 100 tons cooling 240 gpm of water from 54°F to 44°F with 95°F design
dry bulb temperature. Evaporator fouling factor of .00025.
Find:
1. WHR water chiller and AC/AQ condenser selection
2. Compressor power input, chilled water pressure drop
Solution:
1) From Table 13, several WHR selections are possible:
a) WHR 110EA at 110°F CT; 102.5 tons, 107.3 kW, 1596.5 THR, 1.05 kW/ton
b) WHR 115EA at 115°F CT; 101.0 tons, 112.8 kW, 1597.3 THR, 1.12 kW/ton
c) WHR 120EA at 125°F CT; 103.4 tons, 135.1 kW, 1701.5 THR, 1.30 kW/ton
Note that the condensing temperature has significant influence on the chiller efficiency.
Progressing from a) to c) above will require smaller condensers, offset by larger, more
expensive chillers and lessening efficiency.
2) A condenser can be selected with the above information. For this example, a McQuay Model
ACAQ air-cooled condenser will be selected using selection procedures and data contained in
Product Manual PM ACAQ. A model ACD (double row of fans, standard fan speed) will be
used.
a) For the WHR 110EA at a TD of 15 degrees F (110°F - 95°F) no selection appears possible
based on the simple selection method. However, it is close and the graphical method may
give a solution.
b) For the WHR 115EA at a TD of 20 degrees, a Model 175A will do the service.
c) For the WHR 120 EA at a TD of 30 degrees, a Model 115A will do the service.
Selection c) will prove to be considerably lower in first cost but carries a 16 percent efficiency
penalty.
16 Product Manual WHR-2
Page 17
3) Graphical solution to Case a) is shown below.
d) The THR for the WHR
110EA is plotted using two
points; TD=10 degrees
(105°F-95°F) and TD=25
degrees (120°F-95°F).
e) The THR for the ACD 210A
is plotted using its capacity
at TD+15 degrees and
TD=18 degrees.
f) The curves intersect at
TD=16.5 degrees or 111.5°F
condensing temperature.
g) Extrapolating the WHR
capacity at 111.5°F gives
101.5 tons which will meet
the job requirements. It will
be the highest cost but
most efficient unit.
EA Remote Condenser, R-134a
Use the same selection procedures as with R-22 except multiply the values in the R-22 Performance
Tables as follows: Capacity x 0.68, Power x 0.65, EER x 1.05.
Selection Adjustment Factors
Ethylene and Propylene Glycol Factors
WHR units are designed to operate with a leaving chilled fluid temperature from 21°F (-6.1°C) to
60°F (16°C). Leaving chilled fluid temperatures below 40°F (4.6°C) result in suction temperatures at
or below the freezing point of water and a glycol solution is required. The use of glycol in the
evaporator will reduce the performance of the unit. The reduction in performance depends upon
the glycol concentration. This should be taken into consideration during initial system design.
McQuay encourages a minimum concentration of 25% be provided on all glycol applications.
Glycol concentrations below 25% are too diluted for long-term corrosion protection of ferrous
metals and corrosion inhibitors may need to be recalculated. Glycol in the condenser will have a
negligible effect on performance because glycol at higher temperatures will perform with
characteristics similar to water.

Evaporator and Condenser Delta-T Factors
Performance tables are based on a 10°F (5°C) temperature difference through the evaporator and
condenser. A temperature difference other than 10°F (5°C) will result in unit performance being
different from what is shown. Adjustment factors for applications having temperature drops
between 6°F and 16°F (3.3°C to 8.9°C) can be found in Table 3 and Table 4.
Fouling Factor
Performance tables are based on water with a fouling factor of 0.0001 ft2 x hr x °F/BTU (0.0176 m2 x
°C/kW) in the evaporator and 0.00025 ft2 x hr x °F/BTU (0.044 m2 x °C/kW) in water-cooled
condensers according to ARI 550/590-98. As fouling is increased, performance decreases. See
Table 3 and Table 4 for performance with other fouling factors.
To ensure optimum unit operation, proper water treatment must be maintained. Scaling and dirt in a
system will vary significantly depending on local water conditions. Water treatment should be
based on characteristics of the area’s water. Improper or untreated water may lead to scale build up,
erosion and corrosion in both the condenser and evaporator. McQuay will not accept
responsibility for poorly or improperly treated water.

Application Data
Location and Space Requirements
The units are designed for indoor application and must be located in a space where the temperature
is 40°F (4.4°C) or above. Provide clearance of 2 to 3 ft. (609 to 914 mm) on each side and ends for
piping and to help when servicing unit.
Provide clearance at either end of the unit to permit cleaning of condenser tubes or for removal of
tubes from condenser or cooler (see dimensional data). If a door or window is provided at one end
of the unit, the tubes may be replaced through the opening provided.
Foundation
Mount the unit on a level concrete foundation. Floors must be strong enough to support the unit
weight. If necessary, use structural supports to transfer the weight of the unit to the nearest beams.
Vibration Isolation
Vibration mounts are recommended for upper floor installations or where compressor noises might
be objectionable (next to occupied spaces such as offices, meeting rooms, etc.).
Vibration eliminators may be used for water piping connected to the unit to avoid transmission of
water or pump noise into occupied spaces.
System water volume considerations:
All chillers need adequate time to recognize a load change, respond to the change and stabilize
without short cycling the compressor. The water volume in the system and the size of the piping
loop is a critical consideration. Good engineering practice is to have a minimum water volume of
seven times the flow rate (GPM) for comfort cooling applications. For process applications where
the load can change quickly, contact the factory for recommendations. A water storage tank
(provided by others) may be required to increase the system water volume in some systems.
Typical Chilled Water Piping
Flush the system water piping thoroughly before making connections to the unit evaporator. Install
a 40 mesh strainer in the return water line before the inlet to the chiller. Design the water piping so
the chilled water circulating pump discharges into the evaporator inlet.
Connect chilled water return water line to evaporator inlet connection. And the supply water line to
evaporator outlet connection.
Install a flow switch in the horizontal piping of the supply (evaporator outlet) water line.
Provide drain connections at low points in the system to permit complete drainage of the system.
Air vents should be located at the high points in the system to purge air out of the system. A vent
connection on top of the evaporator vessel allows air to be purged. Purge air from the water system
before unit start-up to ensure adequate flow through the evaporator.
Install pressure gauges in the inlet and outlet water lines to the evaporator. Measure pressure drop
through the evaporator to calculate proper flow. Vibration eliminators are recommended in both the
supply and return water lines.
Chilled water piping should be insulated to reduce heat loss and prevent condensation. Chillers not
running in the winter should have their water systems thoroughly drained to protect against
freezing. If the chiller operates year round, or if the system is not drained for the winter, protect the
outdoor chilled water piping against freezing. Wrap the lines with a heater cable and add proper
amount of glycol to the system to further protect the system.

Figure 14, Typical chilled water piping
Condenser Water (EW Units)
Be certain the condenser water enters the bottom connection of the condenser. The condenser
water will exit the condenser from the top connection. Head pressure control must be provided if
the entering condenser water can fall below 60°F. Fan cycling and modulating discharge dampers
on the cooling towers or a three-way bypass valve around the tower is often used. Consult the
tower manufacturer for information on specific applications.
If city or well water is used for condensing, a two-way pressure actuated water regulating valve
should be installed in the outlet piping of each condenser. The condenser purge valve provides a
convenient pressure tap for the regulating valve. The valve can modulate in response to head
pressure. When the compressor shuts down, this valve closes, preventing water from being
siphoned out of the condenser.
Low Temperature Applications
Compressor unloading is acceptable for applications with 35°F or higher leaving fluid temperatures
(LFT). For applications where the LFT is less than 35°F, only full load compressor operation is
allowable. Due to reduced refrigerant flow, motor cooling can become a problem. If compressor
part load operation is required below 35°F LFT, contact the factory for additional requirements. It is
acceptable to use UNT or MicroTech controls for applications with 35°F LFT or lower provided that
only one LFT setpoint is needed.
Ice Storage Applications
Ice storage applications must use Microtech controls. The Microtech has logic to change
setpoints from the low ice making mode to higher normal comfort cooling setpoints. It is important
that the Microtech controller receive a signal to convert from ice mode to normal operating mode.
Microtech includes the logic to keep compressors fully loaded when operating in the ice mode.
The double insulation thickness option is recommend to prevent sweating.
Two Pipe Systems
When the same two pipes are used for both heating and cooling water, several limitations should be
observed. The maximum allowable temperature that the evaporator should experience in a nonoperating mode is 100 degrees Fahrenheit. For unit operation and system changeover from heating
to cooling, the maximum allowable temperature entering the evaporator is 90 degrees Fahrenheit.
System controls provided by others should prevent chiller operation until the loop temperature
drops to 90 degrees. When the loop water temperature ranges between 75 and 90 degrees entering
the evaporator, the high return water staging thermostat should be used to prevent compressor
overloading.
66 Product Manual WHR-2
Page 67
Series or Parallel Operation
Consider system pressure drop when designing the water piping. Parallel piped systems have half
of the total system flow going through the evaporator of each chiller, reducing the individual unit
and total system pressure drop.
Series piped evaporators require that the total system water flows through both evaporators. Not
only is the pressure drop through each evaporator increased but the pressure drops must be added
together to obtain the total evaporator pressure drop. Series piped evaporators normally require
larger circulating pumps for the chilled water system.
Electrical Connection
Every WHR chiller requires field installation of the main supply power plus flow switch and pump
starter relay. A control circuit transformer installed at the factory eliminates the need for field
installation of a separate 115V supply to the control circuit. A separate 115V field connection to the
control circuit can be substituted. A system time clock and remote on-off switch can also be field
installed.
See Figure 5, Field Wiring Diagram , on page 44 for field electrical hookups. The diagram shown
represent all WHR units; however, individual terminal numbers may vary between unit sizes. Each
unit is provided with its specific wiring diagram in the control panel. All wiring must be done
according to local and national codes.
Main Power Supply Disconnect Switch
Every WHR unit uses a single factory installed main power supply terminal block as standard. The
main power supply terminal block will accept single or parallel power supply wiring.
A field installed non-fused disconnect switch with an optional thru-the-door handle (required to
meet NEC Code for disconnects) is available as an option on WHR 040 and above with single point
power supply. The disconnect switch is properly sized for the model and voltage supplied.
A field supplied and installed remote disconnect switch can also be used.
Control Circuit
A control power transformer is standard equipment on WHR units. Terminals are provided in the
unit control center (terminals 1 and NB, typical field wiring diagram) for field connection to a remote
control circuit to a 115V power supply if desired.
Terminals are also provided for field connection of the chilled water flow switch, unit time clock,
ambient thermostat and/or remote on/off switch.
Compressor Time Lockout
A fixed 5-minute solid-state lockout time delays compressor restart after safety cutout or power
interruption, or under irregular cooling load demands.
Interlock Wiring
The condenser water pump should be interlocked to cycle with the compressor(s). This will
prevent the refrigerant pressure from being overly depressed during the off cycle and allows the
energy savings of pump shutdown. Interlock terminals are provided in the unit control panel.

Design Limitations
1. Maximum allowable condenser water pressure is 225 psig (1550 kPa).
2. Maximum allowable evaporator water pressure is 175 psig (1206 kPa).
3. Maximum design saturated discharge temperature (SDT) is 140°F (60°C). SDT=Condensing
temperature + discharge line loss.
4. Maximum allowable water temperature to evaporator in a non-operating cycling is 100°F
(37.8°C). Maximum entering water temperature for operating cycle is 90°F (32.2°C) (during
system changeover from heating to cooling cycle). An optional return water unloading
thermostat is required for return temperatures greater than 75°F (23.4°C).
5. Minimum design leaving water temperature from the evaporator without freeze protection is
42°F (6°C).
6. Contact your McQuay representative for operation with tower condenser water entering the
chiller below 70°F (21.1°C).
7. Compressor unloading is not allowed with leaving chilled fluid temperatures 35°F or less.
8. The optional Microtech control is required for ice storage applications.
9. The maximum altitude for air-cooled condensers is 6,000 feet.
10. Consult factory for ambient operation below 0°F (-17.8°C).
Remote Condenser Refrigerant Piping
General
Careful design of refrigerant piping is necessary for proper system operation. The refrigerant
piping should be designed to accomplish the following:
1. Assure proper refrigerant feed to the evaporator.
2. Provide practical and economical refrigerant line sizes without excess pressure drop.
3. Maintain uniform oil return to the compressor under all load conditions.
4. Refer to the latest version of the ASHRAE Handbook for recommended piping practice.
Limit the length of refrigerant piping by locating the condenser as close to the chiller as possible.
Avoid all unnecessary changes in direction or elevation. On dual circuit units, the condensers must
be selected with separate condenser sections so that the circuits are not combined and precautions
taken to avoid cross-connecting the circuits.
Liquid Line
Where there is a vertical lift from the condenser to the chiller, adequate subcooling must be
provided to prevent liquid flashing before the expansion valve. A shutoff valve should be installed
in the liquid line to allow isolation of the remote condenser.
Discharge line
The discharge line should be trapped at the compressor and looped at the condenser (inverted trap)
to prevent liquid refrigerant from draining back onto the compressor heads. Pressure drop should
be held at a minimum.
