FAQ, GENERAL INFORMATION & OPERATING TIPS
What is a "lockout"?
A lockout occurs when the unit has faulted and cannot correct itself. This mode protects the unit from further
damage. During lockout mode, Emergency Heat will be activated to provide heating if necessary.
What about air filters?
One of the most important things you can do to ensure long system life, high performance and
clean indoor air is to keep the air filter clean. For filters with disposable media, discard the filter
when it is dirty and replace it with a new clean filter. Never attempt to re-use a disposable filter
by cleaning it or placing it in backwards. Electronic filters have a replaceable media. Electrostatic
filters are "permanent" and can be easily washed. Never run the unit without a filter.
The frequency with which you should clean or replace your filter is dependent upon several variables
including the type of filter media, your outdoor environment and your indoor environment. Families
with lots of activities, pets or people sensitive to allergies should clean/replace filters more often.
Contact your dealer with a recommended schedule for filter maintenance.
If you have opted for a permanent electrostatic filter, wash it with a garden hose and a mild household cleaner at least
every 60 days. When placing the filter back in the slot, be sure that the filter is dry and that the arrow on the filter frame
points toward the unit.
If you have an electronic air cleaner installed, check with your dealer or refer to the air cleaner’s owner’s manual for
cleaning instructions.
How do I unclog the drain pan?
In the cooling mode, moisture removed from the air forms as
condensation on the air coil, and the resulting water runs down to the
condensate drain pan. The drain can pick up lint and dirt, especially with
dirty air filters. If overflow occurs, the DRAIN light will come on (in units
equipped with status lights) and the system will shut down. If the water
does not run freely, clean the drain pipe. Dilute a capful of chlorine bleach
in a quart of water and pour the solution in the drain pan once a year. This
helps prevent algae.
To gain access to the drain pan for inspection or cleaning:
• Turn off all power to unit and auxiliary heat.
• Remove the screws holding the fan compartment door closed.
• Lift the door up and pull out at the bottom.
Note:
The drain pan is the black plastic or metal rectangular pan with the drain hole under the air coil.
