EVAPORATORAND CONDENSER COILS - Cleaning of
the coils should only be done by qualified service
personnel. Contact your dealer for the required annual
maintenance.
CONDENSATE DRAIN - The drain pan and condensate
drain line should be checked and cleaned at the same time
the cooling coils are checked by your dealer.
COMPRESSOR - All compressors are factory-shipped
with a normal charge of the correct type refrigeration grade
oil in them and should rarely require additional oil. The
service person must be certain the proper oil level is
maintained in the compressor when it is installed and
running.
CONDENSER FAN -The fan must be kept free of all
obstructions to ensure proper cooling. Contact your dealer
for any required service.
ELECTRICAL CONTROLS and WIRING - Electrical
controls are difficult to check without proper
instrumentation; therefore, if there are any discrepancies in
the operating cycle, contact your dealer and request
service.
REFRIGERATION CIRCUIT - The refrigerant circuit is
difficult to check for leaks without the proper equipment;
therefore, if inadequate cooling issuspected, contact your
local dealer for service.
COMBUSTION AREA and VENT SYSTEM - The
combustion area and vent system should be inspected
visually before each heating season. The normal
accumulation of dirt, soot, rust, and scale can result in loss
of efficiency and improper performance if allowed to build
up.
UNIT PANELS - After performing any maintenance or
service on the unit, be sure all panels are fastened securely
in place to prevent rain from entering unit cabinet and to
prevent disruption of the correct unit airflow pattern, for a
general view of unit and location of access panels.
REGULAR DEALER MAINTENANCE
In addition to the type of routine maintenance you might be
willing to perform, your unit should be inspected regularly
by a properly trained service technician. An inspection
(preferably each year, but at least every other year) should
include the following:
1. Inspection of all flue product passages - including the
burners, heat exchanger, and flue collector box.
2. Inspection of all combustion and ventilation air
passages and openings.
3. Close inspection ofall gas pipes leading to and inside of
your unit.
4. Inspection and, if required, cleaning of the condenser
and evaporator coils.
5. Inspection and, if required, cleaning of the evaporator
drain pan.
6. Inspection and cleaning of blower wheel housing and
motor.
7.
8.
Inspection of all supply-air and return-air ducts for
leaks, obstructions, and insulation integrity. Any
problems found should be resolved at this time.
Inspection of the unit base to ensure that no cracks,
gaps, etc., exist which may cause a hazardous
condition.
9. Inspection of the unit casing for signs of deterioration.
10. Inspection of all electrical wiring and components to
assure proper connection.
11. Inspection for leaks in the refrigerant circuit.
Pressure-check to determine appropriate refrigerant
charge.
12. Inspection of compressor oil level.
13. Operational check of the unit to determine working
conditions. Repair or adjustment should be made at
this time.
Your servicing dealer may offer an economical service
contract that covers seasonal inspections. Ask for further
details.
