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 or

above the indoor temperature during heating season. Be sure the SYSTEM switch or MODE control is in the COOL or HEAT posi- tion and not in the OFF position.

( ) 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.
