WARRANTY CERTIFICATE
Unit 48XZ has a limited warranty. 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 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 SYS-
TEM switch or MODE control is in the COOL or HEAT position
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
unsatisfactory, shut off the unit and call your dealer.
