WARRANTY INFORMATION

A warranty certificate with full details is included with the 
equipment. Carefully review these responsibilities with 
your dealer or service company. The manufacturer will not 
be responsible for any costs found necessary to correct 
problems due to improper setup, improper installation, 
adjustments, improper operating procedure on the part 
of the user, etc. 

Some specific examples of service calls which are not 
included in the limited warranty are:
•  Correcting wiring problems in the electrical circuit 

supplying the equipment.

•  Resetting circuit breakers or other switches.
•  Adjusting or calibrating of thermostat.

Air Filters

 WARNING:

Never operate the unit without a filter in the 
return air system. Dust and lint in the return 
air can build up on the internal components, 
resulting in loss of efficiency, equipment 
damage, and possible fire risk.

•  Inspect and clean or replace air filters at the beginning 

of each heating and cooling season, or more frequently 
if required. A clogged filter could cause airflow related 
problems and reduce the overall efficiency of your unit. 

Always replace disposable filter(s) installed in your 
system only with the same size dimensional filters 
that are being replaced.
