C. Evaporator and Condenser Coils
Cleaning of the coils should only be done by qualified service personnel. Contact your dealer for the required annual maintenance.
D. 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.
E. 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.
F. Condenser Fan
WARNING: Do not poke sticks, screwdrivers, or any other object into revolving fan blades. Severe bodily injury may
result.
The fan must be kept free of all obstructions to ensure proper cooling. Contact your dealer for any required service.
G. Electrical Controls and Wiring
Electrical controls are difficult to check without proper instrumentations; therefore, if there are any discrepancies in the operating cycle, contact
your dealer and request service.
H. Refrigerant Circuit
The refrigerant circuit is difficult to check for leaks without the proper equipment; therefore, if inadequate cooling is suspected, contact your local
dealer for service.
WARNING: System under pressure. Relieve pressure and recover all refrigerant before system repair or final unit
disposal to avoid personal injury or death. Use all service ports and open all flow-control devices, including solenoid valves.
I. 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.
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 and, if required, cleaning of the condenser and evaporator coils.
2. Inspection and, if required, cleaning of the evaporator drain pan.
3. Inspection and cleaning of blower wheel housing and motor.
4. Inspection of all supply-air and return-air ducts for leaks, obstructions, and insulation integrity. Any problems found should be resolved at
this time.
5. Inspection of the unit base to ensure that no cracks, gaps, etc., exist which may cause a hazardous condition.
6. Inspection of the unit casing for signs of deterioration.
7. Inspection of all electrical wiring and components to assure proper connection.
8. Inspection for leaks in the refrigerant circuit. Pressure-check to determine appropriate refrigerant charge.
9. Inspection of compressor oil level by service person to ensure proper oil level is maintained in the compressor when it is installed and
running.
10. 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.
Complete service instructions can be found in the unit Installation, Start-Up and Service Instructions.
Unit PA1P-B and PA2P have a limited warranty. The certificate is located at the back of this book. Be sure to read the warranty carefully to
determine the coverage for your unit.
BEFORE YOU CALL FOR SERVICE, CHECK FOR SEVERAL EASILY-SOLVED PROBLEMS
If insufficient heating or cooling is suspected:
( ) Check for sufficient airflow. Check the air filter for dirt. Check for blocked return-air or supply-air grilles. Be sure they are open and
unobstructed. If these checks do not reveal the cause, call your servicing dealer.
If your unit is not operating at all, check the following list for easy solutions:
( ) Check to be sure that your thermostat temperature selector is set below the indoor temperature during the cooling season. Be sure the system
switch is in the COOL position and not in the OFF position.
