Warranty Certificate

Your unit 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 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 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.
