To avoid equipment damage, do not use these units as
a source of heating or cooling during the construction
process. The mechanical components and filters used
in these units quickly becomes clogged with
construction dirt and debris which may cause system
damage.

To avoid the release of refrigerant into the
atmosphere, the refrigerant circuit of this unit must
only be serviced by technicians which meet local, state
and federal proficiency requirements.

All refrigerant discharged from this unit must be
recovered without exception. Technicians must follow
industry accepted guidelines and all local, state and
federal statutes for the recovery and disposal of
refrigerants.

When a compressor is removed from this unit, system
refrigerant circuit oil will remain in the compressor.
To avoid leakage of compressor oil, the refrigerant
lines of the compressor must be sealed after it is
removed.

Storage

CAUTION: DO NOT store or install CS/CL units in
corrosive environments or in locations subject to
temperature or humidity extremes (e.g., attics,
garages, rooftops, etc.). Corrosive conditions and high
temperature or humidity can significantly reduce
performance, reliability, and service life. Always
move units in an upright position. Tilting units on
their sides may cause equipment damage.

Upon the arrival of the equipment at the job site, immedi-
ately store units in their shipping cartons in a clean, dry
area. Store units in an upright position at all times.
Stack units a maximum of 3 units high. Use pallets to
separate each layer of units. Do not remove equipment
from shipping cartons until equipment is required for
installation.

Unit Protection

Cover CS/CL units on the job site with either shipping
cartons, vinyl film, or an equivalent protective covering.
Cap the open ends of pipes stored on the job site. In areas
where painting, plastering, or the spraying of fireproof
material has not been completed, all due precautions
must be taken to avoid physical damage to the units and

Introduction

ClimateMaster Console Air Conditioner Water Source
Heat Pump units are decentralized room terminals
designed for field connection to a closed-circuit piping
loop. They are offered in capacities ranging from 6,800
to 17,600 BTUH cooling and 8,500 to 21,000 BTUH
heating.

Units are typically installed in perimeter zones, usually
under windows. Supply air is discharged directly into the
conditioned space through discharge grills located in the
top of the unit.

contamination by foreign material. Physical damage and
contamination may prevent proper start-up and may
result in costly equipment clean-up.

Examine all pipes, fittings, and valves before installing
the system components. Remove any dirt found on these
components.

Pre-Installation

Installation, operation and maintenance instructions are
provided with each unit. Before unit start-up, read all
manuals and become familiar with the unit and its
operation. Thoroughly check out the system before
operation. Complete the inspections and instructions
listed below to prepare a CS/CL unit for installation.

Compare the electrical data on the unit nameplate
with ordering and shipping information to verify that
the correct unit has been shipped.

Keep both the chassis and cabinet covered with the
shipping carton until all plastering, painting, and
finish work is complete and it is time to install the
chassis and cabinet.

Verify that the refrigerant tubing is free of kinks or
dents, and that it does not touch other unit compo-
nents.

Inspect all electrical connections. Connections must
be clean and tight at the terminals.

The installation of ConsoleWater Source Heat Pumps and
all associated components, parts and accessories that
make up the installation shall be in accordance with the
regulations of ALL Authorities having jurisdiction and
MUST conform to all applicable Codes. It is the
responsibility of the Installing Contractor to determine
and comply with ALL applicable Codes and Regulations.

NOTE: An Installation Checklist is provided at the
end of this manual. Complete this checklist after all
installation procedures are completed. A periodic
maintenance checklist provided in the Maintenance
section outlines recommended maintenance schedules.
A Start-Up Inspection Log is also included at the end
of this manual to encourage thorough unit checkout
at initial start-up. These checklists are not a substitute
for the detailed information found in the Installation
section of this manual.

INSTALLATION

CS/CL units are typically installed along an outside
wall of the room. Provide adequate space in front of
the unit for service and maintenance. Locate the
Console Air Conditioner so that it provides adequate
air circulation throughout the room.

Unpack the CS/CL Unit from the shipping carton.
Remove the front cabinet by lifting up and away
from the backplate. Protect the cabinet from damage
during installation by returning it to its original vinyl
pack until required.

Using a carpenter's square and a level, ensure the
unit is level. Shim the unit if necessary to assure
proper installation.

CAUTION: Poor or inadequate installation may
result in noisy unit operation or unattractive
installation.

Select the proper fasteners to connect the backplate
securely to the wall.

Fasten the backplate onto the wall through the screw
holes located in the back flange. Secure the subbase
in place.

Make all necessary electrical connections as de-
scribed in the Electrical Wiring section of this
manual. Consult the wiring diagram to ensure proper
hook-up.

CAUTION: RH Units - Entering Water is upper pipe.

LH Units - Entering Water is lower pipe.

7. Connect the final piping as described in the Supply and

Return Piping and Condensate Piping section of the
manual. Install shut-off valves, piping and/or hoses
and other accessories as specified.

Before making the final water connections, flush the
system as described in the Start Up section of this
manual. After flushing the system, connect piping
and hoses to the proper supply, return and conden-
sate connections of the unit.

NOTE: When necessary, use adapters to connect
hoses.

Reinstall the front cabinet by carefully lowering the
front cabinet over the chassis onto the backplate.

10. Install any other system components as required

following manufacturer's instructions.

Supply and Return Hoses

Optional pressure-rated hose assemblies are available for
use with ClimateMaster CS/CL Units. Use the following
guidelines when installing supply and return hose
assemblies.

Install supply and return hoses fitted with swivel-
joint fittings at one end to prevent the hose from
twisting.

Use male adapters to secure the hose assembly to the
unit and the riser.

Do not allow the hose to twist during installation.
Twisting may damage the hose wall or the rubber
compound.

Use pipe joint compound sparingly on the male pipe
threads of the fitting adapters.

Prevent sealant from reaching the flared surfaces of
the joint.

Do not use pipe joint compound when teflon thread
tape is pre-applied to hose assemblies or when
flared-end connections are used.

Maximum torque which may be applied to brass
fittings is 30 foot pounds. When a torque wrench is
not used, tighten brass fittings finger-tight plus one
quarter turn.

Tighten steel fittings as necessary.

Shut-off/balancing valves, flow indicators, and drain
tees in the supply runout and return at each floor aid
in loop balancing and servicing.

Page 5

Supply and Return Piping

System piping MUST comply with all applicable codes.

Install a drain valve at the base of each supply and
return riser to enable system flushing at start-up and
during routine servicing.

Install shut-off/balancing valves and unions at each
unit to allow unit removal for servicing.

NOTE: If flex hoses are used, unions are not
necessary.

Install strainers at the inlet of each system circulating
pump.

NOTE: Since loop temperature is normally between
60

and 90

F, pipe sweating and heat loss does not

occur at normal ambient conditions. Insulation must
be installed on loop water piping on those sections
which run through unheated areas or are located
outside the building.

Condensate Piping

Connect the unit condensate drain to the building
condensate drain with a flexible, nonpressure-rated 5/8
inch I.D. plastic hose. Avoid kinks in this hose to ensure
an unobstructed flow of condensate from the unit to the
drain.

The horizontal run of the condensate hose is usually too
short to pose any drainage problems however, the
horizontal run of condensate line ought to be pitched at
least one inch for every 10 feet of run in the direction of
flow. Avoid low points and unpitched piping since dirt
collects in these areas and may cause stoppage and
overflow.

Field installation of a trap or vent is not required unless
specified by local codes. CS/CL units are designed in a
blow-through configuration. The condensate drain pan is
located on the outlet side of the blower so that the
pressure in the drain pan is higher than the atmosphere.

Electrical Wiring

To avoid possible injury or death due to electrical
shock, open the power supply disconnect switch and
secure it in an open position during installation.

CAUTION: Use only copper conductors for field
installed electrical wiring. Unit terminals are not
designed to accept other types of conductors.

All field installed wiring, including the electrical ground,
MUST comply with the National Electrical Code as well
as applicable local codes. In addition, all field wiring
must conform to the Class II temperature limitations
described in the NEC.

Consult the unit wiring diagram located on the inside of
the compressor access panel to ensure proper electrical
hookup. The installing (or electrical) contractor must
make the field connections shown in Figure 1 when using
field supplied disconnect.

Modify the transformer connection for units rated
208-230 volts with a 24-volt transformer when the actual
power supply is 230 volts. Refer to the unit wiring
diagram for details of this procedure.

Make all final electrical connections with a length of
flexible conduit to minimize vibration and sound
transmission to the building.

Optional Night Setback Control

An optional hard-wired night setback system (NSB) is
available. This system consists of a central (or zone)
night setback control panel and an individual NSB relay
at each heat pump.

Refer to unit wiring diagrams for specific night setback
options and correct method of wiring.

Page 6

Optional CMC-2000 Series Electronic
Controller

A solid state CMC-2000 Series controller is available as
an option to the standard electro-mechanical line voltage
thermostat control.

The CMC-2001 Controller is standard when a 24V
remote thermostat is used.

Refer to the CMC-2000 Series Electronic Controller
Installation and Operating Manual (p/n 69626515)
shipped with the controller for installation and operating
instructions.

Optional Wall-Mounted Thermostat

CS/CL WSHP units are built with standard internal
thermostats in either manual changeover (MCO) or
automatic changeover (ACO) configuration. No external,
field-installed low-voltage wiring is required.

When desired, the unit can be furnished with a 24-volt
control circuit which is field-wired to a ClimateMaster-
supplied accessory remote thermostat.

Zone integrity must be maintained to efficiently control
units or groups of units. Unless zones of control are
considered and accounted for, adjacent units may operate
in heating and cooling modes simultaneously.

Low-voltage wiring between the unit and the wall
thermostat must comply with all applicable electrical
codes (i.e., NEC and local codes), and be completed
before the unit is installed.

Table 2 lists recommended wire sizes and lengths to
install the thermostat. The total resistance of low-voltage
wiring must not exceed 1 ohm. Any resistance in excess
of 1 ohm may cause the control to malfunction because
of high voltage drop.

System Cleaning and Flushing

Cleaning and flushing the unit is the single most impor-
tant step to ensure proper start-up and continued efficient
operation of the system. Follow the instructions below to
properly clean and flush the system:

To prevent injury or death due to electrical shock or
contact with moving parts, open unit disconnect
before servicing unit.

Verify that electrical power to the unit is discon-
nected and that the heat rejector is de-energized

Install the system with the supply hose connected
directly to the return riser valve. Use a single length
of flexible hose as illustrated in Figure 2 below.

NOTE: When one hose is too short to make the
connection without exceeding the minimum bend
radius of the hose, substitute two length of flexible
hose joined together with a field-supplied, standard
MPT coupling. Use the adapter provided with the
hose kit as shown in Figure 3.

Fill the system with water, leaving the air vents
open. Bleed all air from the system but do not allow
the system to over flow. Check the system for leaks
and make any required repairs. Adjust the water and
air level in the expansion tank.

With strainers in place, start the pumps. Systemati-
cally check each vent to ensure that all of the air is
bled from the system.

Verify that make-up water is available and adjusted
to properly replace any space remaining when all
air is evacuated. Check the system for leaks and
make any additional repairs required.

START-UP PREPARATION

Set the boiler to raise the loop temperature to
approximately 85

F. Open the drain at the lowest

point in the system. Verify that make-up water
replacement rate equals rate of bleed. Continue to
bleed the system until the water appears clean or for
at least three hours whichever is longer.

Completely drain the system.

Refill the system with clean, chemically treated
water. Since water varies for each locality, contact a
local water treatment company for the correct
cleaning chemicals to use in your area.

CAUTION: To avoid possible damage to piping
systems constructed of plastic piping, DO NOT allow
loop temperature to exceed 110

Circulate the solution for a minimum of eight to 24
hours. At the end of this period, shut off the circulat-
ing pump and drain the solution. Repeat system
cleaning if necessary.

10. When the cleaning process is complete, remove the

short-circuit hoses. Re-connect the hoses to the
proper supply and return the connections to the unit.
Refill the system and bleed off all air.

11. Test the system pH with litmus paper. The system

water should be slight alkaline (pH 7.5 to 8.5). Add
chemicals as appropriate to maintain acidity levels.

CAUTION: DO NOT use "Stop-Leak" or any similar
chemical agent in this system. Addition of these
chemicals to the loop water will foul the system and
will inhibit unit operation.

12. When the system is successfully cleaned, flushed,

refilled and bled, check the main system panels,
safety cutouts and alarms. Set controls to properly
maintain loop temperature.

NOTE: Use standard coupling (field-supplied) and

hose adapters to join 2 hoses

Freeze Protection for Water System: Verify

freeze protection is provided for the outdoor portion
of the loop water system. Inadequate freeze protec-
tion can lead to expensive tower and system piping
repairs.

CAUTION: To avoid equipment damage, DO NOT
leave system filled in a building without heat during
the winter unless anti-freeze is added to system water.
Condenser coils never fully drain by themselves and
will freeze unless winterized with anti-freeze.

10. System Water Loop: Verify all air is bled from
the system. Air in the system impedes unit operation
and causes corrosion in the system piping.

11. Unit Filters: To avoid system damage, ensure
the unit filter is clean.

12 Unit Fans: Manually rotate fans to assure free
rotation. Ensure fans are properly secured to the fan
shaft. Do not oil fan motors on start-up since they
are lubricated at the factory.

13. System Control Center: To ensure control of the
temperature set-points for operation of the system’s
heat rejector and boiler, examine the system control
and alarm panel for proper installation and opera-
tion.

14. Miscellaneous: Note any questionable aspects of
the installation.

Voltage: Ensure voltage is within the utilization

range specifications of the unit compressor and fan
motor.

System Water Temperature: Ensure it is within

an acceptable range to facilitate start-up. (When
conducting this check, also verify proper heating and
cooling set points.)

System Water pH: Verify system water acidity.

(pH = 7.5 or 8.5) Proper pH promotes the longevity
of hoses and heat exchangers.

System Flushing: Properly clean and flush

system periodically. Ensure all supply and return
hoses are connected end-to-end to facilitate system
flushing and prevent fouling of the heat exchanger
by system water. Water used in the system must be of
potable quality and clean of dirt, piping slag, and
chemical cleaning agents.

Closed-Type Cooling Tower or Open Tower

with Heat Exchanger: Check equipment for proper
temperature set points and operation.

Balanced Water Flow Rate to Heat Pump:

Verify the inlet and outlet water temperatures are
recorded as each heat pump unit is started. This
check will eliminate nuisance unit trip-outs resulting
from water velocities which are either too low or too
high; it can also prevent the occurrence of erosive
water flow rates.

Standby Pump: Verify the standby pump is

properly installed and in operating condition.

System Controls: To ensure no catastrophic

system failures occur, verify system controls are
functioning and the sequencing is correct.

When the installation is complete and the system is cleaned and flushed, follow the System Checkout procedure outline below.

When the disconnect switch is closed, high voltage is
present in some areas of the electrical panel. Exercise
caution when working with the energized equipment.

Adjust all valves to the full open position and turn
on the line power to all heat pump units.

Operate each unit first in the cooling mode. Room
termperature should be in the normal range (i.e.,
approximately 70

to 75

F DB and 61

to 65

WB). Loop water temperature entering the heat
pumps should be at least 70

F but not in excess of

110

F. Refer to Table 3 for more specific informa-

tion on the operating parameters of CS/CL units.

NOTE: Three factors determine the operating limits
of a CS/CL unit: (1) returen air temperature, (2)
water temperature and (3) ambient temperature.
Whenever any one of these factors is at a minimum or
maximum level, the other two factors must be at
normal levels to ensure proper unit operation. Flow
rates must be at ARI rated standards.

Unit Start-up / Cooling

a. Turn the unit thermostat to the cooling position
and turn the fan speed switch to "HI". If the unit has
an optional MCO thermostat, set the selector switch
to cool. Both the fan and compressor should run.

b. Check for cool air delivery at system grille a few
minutes after the units have begun to operate. List
the identification number of any machines that do
not function at this time.

c. Check the elevation and cleanliness of the
condensate lines; any dripping could be a sign of a
blocked line.

3. Operate each heat pump in the heating cycle immedi-

ately after checking cooling cycle operation. A time
delay will prevent the compressor from
re-starting for approximately three minutes.

Operating Limits

Environment: This equipment is designed for indoor
installation ONLY.

Power Supply: A voltage variation of +/- 10% of
nameplate utilization voltage is acceptable. Three phase
system imbalance must not exceed 2%.

CS Unit Starting Conditions: CS Units start and
operate in an ambient of 50

F with entering air at 50

entering water at 60

F and with both air and water at the

flow rates used in the ARI Standard 320-86 rating test for
initial start-up in winter.

CL Unit Starting Conditions: CL Units will start and
operate in an ambient of 40

F with entering air at 40

with both air and water at the flow rates used in the ARI
Standard 320-86 rating test, for initial start-up in winter.

Operating Limits

Note: Minimum air and water conditions can only be used
at ARI flow rates. Only one maximum or minimum value
may be used with CS Units. All other parameters must be
at normal conditions. CL Units may have up to two values
at maximum or minimum with all other parameters at
normal conditions.

NOTE: These operating limits are not normal or
continuous operating conditions. It is assumed that
such a start-up is for the purpose of binging the
building space up to occupancy temperature.

Use the procedure outlined below to initiate proper unit start-up:

CS Units

CL Units

Page 10

Unit Start-Up / Heating

a. Adjust the unit thermostat to the warmest setting
and turn the fan speed switch to "HI". If the unit has
an optional MCO thermostat, set the selector switch
to heat. The blower should start immediately and
after the time delay is complete the compressor will
start.

b. Once the unit has begun to run, check for warm
air delivery at the unit grille. Again the installing
contractor must list the serial number of any
machine that does not function.

Log the unit operating conditions at initial start-up
for each unit to establish a permanent operating
record.

If the unit fails to operate, conduct the following
checks:

a. Check the voltage and current. They should
comply with the electrical specifications described
on the unit nameplate.

b. Look for wiring errors. Check for loose terminal
screws where wire connections have been made on
both the line and low-voltage terminal boards.

c. Check for dirty filters. A clogged filter will cause
safety cutouts to stop unit operation.

d. Check the supply and return piping. They must be
properly connected to the inlet and outlet connec-
tions on the unit.

e. If the fan fails to operate, check to see that the fan
wheel turns freely and that it is secured to the shaft.
Also, determine whether the fan operates during
both the heating and cooling modes.

f. If the checks described above fail to reveal the
problem and the unit still will not operate, contact a
trained service technician to ensure proper diagno-
sis and repair of the equipment.

Page 11

Perform the maintenance procedures outlined below at
the intervals indicated.

To prevent injury or death due to electrical shock or
contact with moving parts, open unit disconnect
switch before servicing unit.

FILTERS: Inspect filters. Establish a regular mainte-
nance schedule. Clean/replace filters frequently depend-
ing on need.

To remove the filter from the CS/CL unit, slide the filter
out of its frame located in the return air opening at the
bottom front of the unit. When re-installing the filter, use
the slide-in rails of the filter frame to guide the filter into
the proper position.

CAUTION: To avoid fouled machinery and extensive
unit clean-up, DO NOT operate units without filters
in place. DO NOT use equipment as a temporary
heating or cooling source during construction.

CONDENSATE PANS: Check condensate drain pans
for algae growth every three months. If algae growth is
apparent, consult a water treatment specialist for proper
chemical treatment. The application of an algaecide
every three months will typically eliminate algae prob-
lems in most locations.

FAN MOTORS: ClimateMaster CS/CL heat pumps are
fully lubricated. Do not lubricate.

UNIT INSPECTION: Visually inspect the unit at least
once a month. Pay special attention to hose assemblies.
Repair any leaks and replace deteriorated hoses immedi-
ately. Note any signs of deterioration or cracking.

COMPRESSOR: Conduct an amperage check annually
on the compressor and fan motor. Amperage draw should
not exceed normal full load amps. Maintain a log of
amperage to detect deterioration prior to component
failure.

Safety Control Reset

All ClimateMaster heat pumps are furnished with high-
pressure, low-pressure and low-temperature cutouts to
prevent the machine from operating at abnormal condi-
tions of temperature or water flow.

The contacts of the high-pressure control used on CS/CL
units is designed to open at 380 psi and automatically
re-close at 300 psig. The contacts of the low-temperature
switch open at 33

F and reclose at 40

F. A lockout

relay, electrically linked with these cutouts, interrupts
unit heating or cooling operation.

The machine must be reset manually. Reset is accom-
plished by pressing the STOP button and then pushing
either HI HEAT, LO HEAT, HI COOL or LO COOL to
restart the unit in the desired mode of operation. (The
CS/CL unit can also be reset by opening and closing the
supply power disconnect switch.)

NOTE: If the unit must be reset more than twice,
check the unit for a dirty filter, abnormal entering
water temperature, inadequate or excessive water
flow, and internal malfunctions. If the unit continues
to cut out, contact a trained service technician.

MAINTENANCE

When replacing the compressor contactor or lockout
relay in a unit with electromechanical controls, use
only ClimateMaster replacement parts. Substitution
of other components may result in an inoperative
safety circuit and may cause a hazardous condition.

HEAT EXCHANGERS: Clean the heat exchangers
annually. Inspect heat exchangers regularly and clean
more frequently if the unit is located in a “dirty”
environment.
