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.
