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 CCE unit for installation.
1. Compare the electrical data on the unit nameplate
with ordering and shipping information to verify
that the correct unit has been shipped.
2. 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.
3. Verify that the refrigerant tubing is free of kinks
or dents, and that it does not touch other unit
components.
4. Inspect all electrical connections. Connections
must be clean and tight at the terminals.
To avoid equipment damage, do not use these units as
a source of heating or cooling during the construction
process. The mechanical components and lters 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 prociency
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.
General Information
Inspection
Upon receipt of shipment, carefully check the shipment
against the bill of lading. Verify all CCE units have been
received. Inspect each unit for damage. Be certain the
carrier makes proper notation on the delivery receipt
of all shortages and noticeable damage and he com-
pletes a Carrier Inspection Report. Concealed damage
not discovered during unloading must be reported to
the carrier within fifteen (15) days of receipt of ship-
ment. NOTE: It is the responsibility of the purchaser
to file all necessary claims with the carrier. Notify the
ClimateMaster Traffic Department within fifteen (15)
days of receipt of all damaged shipments.
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 2-5.6
kW cooling.
Units must be installed indoors and are typically
installed in perimeter zones, usually under windows.
Supply air is discharged directly into the conditioned
space through discharge grille located in the top of
the unit.
Storage
CAUTION: DO NOT store or install CCE units in
corrosive environments or in locations subject to
temperature or humidity extremes (e.g., attics, ga-
rages, 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,
immediately 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 CCE 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 fire-
proof material has not been completed, all due precau-
tions must be taken to avoid physical damage to the
units and 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.

Installation
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 jurisdic-
tion and MUST conform to all applicable Codes. It is
the responsibility of the Installing Contractor to de-
termine and comply with ALL applicable Codes and
Regulations.
NOTE: An Installation Checklist is provided in this man-
ual. Complete this checklist after all installation proce-
dures are completed. A periodic maintenance checklist
provided in the Maintenance section outlines recom-
mended maintenance schedules. A Start-Up Inspection
Log is also included at the end of this manual to encour-
age thorough unit checkout at initial start-up. These
checklists are not a substitute for the detailed informa-
tion found in the Installation section of this manual.
1. CCE 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.
2. Unpack the CCE 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.
3. Remove compressor isolation plate shipping
screws (4) as shown in Figure 1a.
4. 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 installa-
tion.
5. Select the proper fasteners to connect the
backplate securely to the wall.
6. Fasten the backplate onto the wall through the
screw holes located in the back flange. Secure the
subbase in place.
7. Make all necessary electrical connections as
described in the Electrical Wiring section of this
manual. Consult the wiring diagram to ensure
proper hook-up.
8. 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.
9. 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
condensate connections of the unit.
NOTE: When necessary, use adapters to
connect hoses.
10. Install any other system components as required
following manufacturer's instructions.
11. After Start-up, reinstall the front cabinet by
carefully lowering the front cabinet over the
chassis onto the backplate.
Supply and Return Hoses
Optional pressure-rated hose assemblies are available for
use with ClimateMaster CCE Units. Use the following
guidelines when installing supply and return hose
assemblies.
1. Install supply and return hoses fitted with swivel-
joint fittings at one end to prevent the hose from
twisting.
2. Use male adapters to secure the hose assembly to
the unit and the riser.
3. Do not allow the hose to twist during installation.
Twisting may damage the hose wall or the rubber
compound. (Not all models)
4. Use pipe joint compound sparingly on the male
pipe threads of the fitting adapters.
5. Prevent sealant from reaching the flared surfaces
of the joint.
6. Do not use pipe joint compound when teflon
thread tape is pre-applied to hose assemblies or
when flared-end connections are used.
7. Maximum torque which may be applied to brass
fittings is 30 ft-lbs. When a torque wrench is not
used, tighten brass fittings finger-tight plus one
quarter turn.
8. Tighten steel fittings as necessary.
9. Shut-off/balancing valves, flow indicators, and
drain tees in the supply runout and return at each
floor aid in loop balancing and servicing.
CAUTION: Loop Fluids should be of good
quality with no more than 0.50 ppm of
chlorides w/ Cu (125 ppm w/ CuNi) to prevent
corrosion and should also be filtered to a
maximum 800 micron particle size to prevent
erosion of the heat exchangers.
Supply and Return Piping
System piping MUST comply with all applicable codes.
1. Install a drain valve at the base of each supply and
return riser to enable system flushing at start-up
and during routine servicing.
2. 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.
3. Install strainers at the inlet of each system
circulating pump.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
Installation
NOTE: If loop temperatures are expected below the am-
bient dew point, the optional internal insulation package
must be ordered. Insulation must also be installed on
loop water piping on those sections which run through
unheated areas or are located outside the building.
Condensate Piping
Unit is supplied with condensate drain hose, 15.9mm
I.D. flexible plastic nonpressure-rated, protruding from
piping side of unit. Connect this hose to building drain.
Avoid making kinks in hose to ensure an unobstructed
flow of condensate from the unit to the drain. DO NOT
twist, pull hose out, or push excess hose into unit. If
hose will not connect to your building drain several
options include, relocate end of building drain, add to
or cut hose, use hard plastic or copper elbow fittings
for tight radii (put inside hose). Keep hose positioned
within or over subbase area so hose does not interfer
with front cabinet. Cabinet should not push or reroute
hose. Clamp all joints watertight. Check
for leaks.
Internally the drain hose is clamped to drain pan and
pitched correctly. Horizontal runs of condensate hose
should be pitched downward 6mm (1/4 inch) minimum
for every 300MM of hose. Avoid low points and unpitch-
ing because dirt collects in these areas and may cause
blockage. If blocked the condensate level in
drain pan increases, when level gets too high, CCE unit
has sensor switch that will shut unit off, overflow may
still occur.
Building drain connection if parallel with floor the
height can be up to 38mm above subbase for proper
pitch and correct drainage, up to 130mm above is
allowable but drainage will be slower. When 65 to
130mm above the hose inside unit will act as a trap.
Heights more than 130mm above subbase are NOT
allowable (condensate overflow may occur). Check if
your unit has a disconnect box option, this limits build-
ing drain locations. See unit Configuration pages.
Field installation of a trap or vent is not required unless
specified by local codes. CCE 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
atmosphere.
When drain connection is completed check for proper
drainage and leaks. Correct if necessary.
If trap is used, check and clean often. See
Maintenance Instructions.

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 low
voltage 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.
Units have dual voltage (220-240V) control transformer.
The units are shipped for 240V operation. Modify the
transformer connection when the actual power supply
is 220 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 Wall-Mounted Thermostat
CCE 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.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
System Cleaning and Flushing
Cleaning and flushing the unit and system is the single
most important step to ensure proper start-up and
continued efficient operation of the system. Follow
the instructions below to properly clean and flush the
system:
DO NOT FLUSH SYSTEM THROUGH THE UNIT!
To prevent injury or death due to electrical shock or
contact with moving parts, open unit disconnect before
servicing unit.
1. Verify that electrical power to the unit is
disconnected and that the circulation pump is
de-energized.
2. Connect the supply hose 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.
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.
4. With strainers in place, start the pumps.
Systematically check each vent to ensure that all
of the air is bled from the system.
5. Verify that make-up water is available and
adjusted to properly replace any space remaining
when all air is evacuated. Pressure test and inspect
the system for leaks and make any additional
repairs required.
Start-Up Preparation
6. 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.
7. Completely drain the system.
8. 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 43 °C.
9. Set the boiler to raise the loop temperature to
approximately 29.4°C. Circulate the solution for
a minimum of 8 to 24 hours. At the end of this
period, shut off the circulating pump and drain the
solution. Repeat system cleaning if necessary.
10. When the cleaning process is complete, remove
the short-circuit hoses. Connect the hoses to the
proper supply and return 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.

CAUTION: To avoid equipment damage, DO
NOT leave system filled with water in a building
without heat during the winter unless anti-freeze
is added to system water. Coax coils never fully
drain by themselves and will freeze unless win-
terized 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 unit damage and
maximum performance, 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 operation.
14. Miscellaneous: Note any questionable aspects
of the installation.
1. Voltage: Ensure voltage is within the
utilization range specifications of the unit
compressor and fan motor.
2. 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.)
3. System Water pH: Verify system water
acidity. (pH = 7.5 or 8.5) Proper pH
promotes the longevity of hoses and heat
exchangers.
4. 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.
5. Closed-Type Cooling Tower or Open Tower
with Heat Exchanger: Check equipment
for proper temperature set points and
operation.
6. 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.
7. Standby Pump: Verify the standby pump
is properly installed and in operating
condition.
8. System Controls: To ensure no catastrophic
system failures occur, verify system controls
are functioning and the sequencing is
correct.
9. Freeze Protection for Water System: Verify
freeze protection is provided for the
outdoor portion of the loop water system.
Inadequate freeze protection can lead to
expensive tower and system piping repairs.
When the installation is complete and the system is cleaned and flushed, follow the System Checkout
procedure outline below.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
NOTE: This equipment is designed for indoor
installation ONLY.
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.
1. Adjust all valves to the full open position and turn
on the line power to all heat pump units.
2. Operate each unit first in the cooling mode.
Operate each heat pump in the heating
cycle immediately after checking cooling
cycle operation. A time delay will prevent the
compressor from re-starting for approximately
three minutes. Room temperature should be in
the normal range (i.e., approximately 10-27°C DB.
Loop water temperature entering the heat pumps
should be at least 4°C but not in excess of 43°C.
Refer to Table 3 for more specific information on
the operating parameters of CCE units.
NOTE: Three factors determine the operating
limits of a CCE unit: (1) return 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.
3. If units do not operate correctly refer to the
troubleshooting section (pg. 11). If unit cannot
be repaired, record on form on last page of this
manual and continue with start-up procedure.
Unit Start-up / Cooling
4. High Cooling -Turn the unit thermostat to the
coolest 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.
Check for cool air delivery at unit grille 15 minutes
after the unit is operating. List the identification
number of any machines that do not function at
this time.
Check the elevation and cleanliness of the
condensate lines; any dripping could be a sign of
a blocked line.
Operating Limits
Environment: This equipment is designed for indoor
installation ONLY.
Power Supply: A voltage variation of +/- 10% of
nameplate utilization voltage is acceptable.
CCE Unit Starting Conditions: CCE Units start and
operate in an ambient of 10°C with entering air at 10°C,
entering water at 16°C and with both air and water at
the flow rates used in the ARI Standard 13256-1 rating
test for initial start-up in winter.
Table 3 Operating Limits
Unit Start-Up
Note: Minimum air and water conditions can only
be used at ARI flow rates. CCE 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 for
continuous operating conditions. It is assumed that
such a start-up is for the purpose of bringing the
building space to desired occupancy temperature.
Use the procedure outlined below to initiate proper
unit start-up:

7. High Heat - 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. 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.
8. Low Heat - Disregard if unit is only one speed.
Select low fan. Airflow should decrease and
compressor should continue to operate.
9. Unit Cycles Off - Slowly turn thermostat toward
cooler position. Both fan and compressor should
shut off when thermostat set point equals room
temperature. Note room temperature must be
above 19°C or unit will not cycle off.
10. Fan Only - Select fan speed. Only fan should
operate.
11. Off - Unit should not operate
Troubleshooting
1. 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
connections on the unit.
e. If the fan fails to operate,check wiring and 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. Check if circuit board is flashing a fault code. See
CXM/DXM AOM for details.
g. Check that the unit has not cycled off on
thermostat.
h. 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 diagnosis and repair of the equipment.
2. Record any unit that does not operate correctly.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
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 maintenance
schedule. Clean/replace filters frequently depending
on need.
To remove the filter from the CCE 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 problems in most locations. Check condensate
hose for leaks and blockage and correct any problems.
FAN MOTORS: All units have lubricated fan motors.
FAN MOTORS SHOULD NEVER BE LUBRICATED
UNLESS OBVIOUS, DRY OPERATION IS SUSPECTED.
Periodic maintenance oiling is not recommended
because it will result in dirt accumulating on excess oil
and cause eventual motor failure. Conduct annual dry
operation check and amperage check to ensure amp
draw is no more than 10% greater than that indicated
by serial plate data.
UNIT INSPECTION: Visually inspect the unit at
least once a month. Pay special attention to hose
assemblies. Repair any leaks and replace deteriorated
hoses immediately. 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.
HEAT EXCHANGERS: Water Coil Maintenance –
Generally water coil maintenance is not needed
however, if the installation is located in a system with a
known high dirt or debris content, it is best to establish
with the owner a periodic maintenance schedule so the
coil can be checked regularly. These dirty installations
are a result of the deterioration of iron or galvanized
piping or components in the system or open cooling
towers requiring heavy chemical treatment and
mineral buildup through water use. Should periodic
coil cleaning be necessary, use standard coil cleaning
procedures which are compatible with both the heat
exchanger material and copper water lines. Generally,
the more water flowing through the unit, the less
chance for scaling, however flow rates over 0.0538 l/s
per kW can produce water (or debris) velocities that can
erode the heat exchanger wall and ultimately produce
leaks.
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
conditions of temperature or water flow.
The contacts of the high-pressure control used on CCE
units is designed to open at 2600 kPa and automatically
re-close at 2100 kPa. The CXM or DXM control monitors
this and other functions such as refrigerant temperatures
and pressures and condensate overflow and will interrupt
unit heating or cooling operation.
The machine must be reset manually. Reset is
accomplished 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 CCE 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.
