What if my unit does not operate properly?
Before you call your WaterFurnace dealer for service, check these service hints:
Check air filters. Depending upon filter type, clean or replace if necessary. (See below.)
Make sure the thermostat is set properly.
Check to make sure the electrical disconnect switches are in the ON position. Both the unit and auxiliary heat
(if present) must be powered for proper operation.
Check for a tripped circuit breaker or a blown fuse in your home or building’s main power box. Reset breaker
or replace fuse.
If either the disconnect switch or the circuit breaker continues to trip after you reset it, call your WaterFurnace
dealer immediately to prevent damage to your unit.
Check the thermostat indicator lights to ensure proper operation of the system.
Check the unit status lights on the front of the unit to ensure the unit is operating properly.
If you can’t determine the problem, call your WaterFurnace dealer promptly.
What is a "lock out"?
A lock out occurs when the unit has faulted and cannot correct itself. This mode protects the unit from further
damage. During lock out mode, Emergency Heat will be activated to provide heating if necessary.
What about air filters?
One of the most important things your can do to ensure long system life, high perfor-
mance 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 in 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 en-
vironment. Families with lots of activities, pets or with 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 arrow on the
filter frame points toward the unit. (See page 51 for more information.)
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. (See page 50 for more information.)
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 to prevent algae.
To gain access to the drain pan for inspection or cleaning:
1. Turn off all power to unit and auxiliary heat.
2. Remove the screws holding the fan compartment door closed.
3. 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 in the middle, under the air coil.
