!WARNING

PERSONAL INJURY AND UNIT DAMAGE HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

Do not insert sticks, screwdrivers, or any other objects into revolving fan blades.

The fan must be kept free of all obstructions to ensure proper cool- ing. Contact your dealer for any required service.

Electrical Controls and Wiring

Electrical controls are difficult to check without proper instrumenta- tion. If there are any discrepancies in the operating cycle, contact your local dealer and request service.

Refrigerant Circuit

The refrigerant circuit is difficult to check for leaks without the prop- er equipment. If inadequate cooling is suspected, contact your local dealer for service.

!WARNING

EXPLOSION AND BURN HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

System under pressure. Relieve pressure and recover all refrigerant before system repair or final unit disposal. Use all service ports and open all flow-control devices, including solenoid valves.

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 pat- tern.

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 outdoor and indoor coils.

2.Inspection and, if required, cleaning of the indoor coil 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.

Warranty Certificate

Your unit has a limited warranty. Be sure to read the warranty care- fully 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 the temperature specified by your User Interface is set below the indoor temperature during the cooling sea- son or above the indoor temperature during heating season. Be sure the User Interface is set to COOL or HEAT and not OFF.

( ) If your unit still fails to operate, call your servicing dealer for troubleshooting and repairs. Specify the model and serial numbers of your unit. (Record them in this manual in the space provided.) If the dealer knows exactly which unit you have, he may be able to offer suggestions over the phone, or save valuable time through knowledgeable preparation for the service call.

In Case of Trouble

If you perform the steps above and unit performance is still unsatis- factory, shut off the unit and call your dealer.
