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. 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,

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 season
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
unsatisfactory, shut off the unit and call your dealer.
