WARNING: Never operate your unit without filters in place. Failure to heed this warning may result in damage to the blower motor and/or compressor. An accumulation of dust and lint on internal parts of your unit can cause loss of efficiency and, in some cases, fire.

B.Fans and Fan Motor

Periodically check the condition of fan wheels and housings and fan-motor shaft bearings. No lubrication of condenser- or evaporator-fan bearings or motors is required or recommended.

C.Evaporator and Condenser Coils

Cleaning of the coils should only be done by qualified service personnel. Contact your dealer for the required annual mainte- nance.

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 instrumen- tations; 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.

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 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 condi- tions. 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.
