1.Make sure blower selector switch is on “Auto.”

2.Set fan switch to “AUTO.”

3.Set system switch to “HEAT.”

4.Set thermostat temperature selector switch to desired comfort level.

To Balance Air Distribution

1.On a typical day, set thermostat selector to desired comfort level and operate system for several hours with all air registers open.

2.With system on, check temperature in all rooms.

3.Partially close registers in rooms that are too warm (in heating mode) or too cool (in cooling mode) and in rooms that are infrequently occupied.

4.Re-check room temperature and adjust registers as needed.

To Shut Off System

1.Make sure blower selector switch is on “Auto”.

2.Set thermostat temperature selector to lowest temperature setting, OR...

3.For thermostats with optional sub-base (see Figure 1), or for systems with relay box, set system switch to “OFF.”

WARNING:

To prevent hazard of electrical shock and injury from moving parts, be certain the thermostat is off and the furnace circuit breaker(s) are in the “OFF”position before servicing.Close and properly latch the outer door after doing the following recommended maintenance.

MAINTENANCE INSTRUCTIONS

Regularly

NOTE: If a cooling coil is installed, furnace fi lter is not used.

1.Replace furnace air fi lter (see Figure 1), OR...

2.Remove coil fi lters, wash, and allow to dry. Re-install coil fi lters to original positions.

3.Vacuum or wipe clean interior of furnace cabinet.

4.Clean all lint and dust from around fur- nace.

Every Six Months

1.Vacuum or wipe away any dust or lint on blower motor.

Before Each Heating Season

NOTE: If a cooling coil is installed, furnace fi lter is not used.

1.Replace furnace air fi lter (see Figure 1),

OR

2.Remove coil fi lters, wash, and allow to dry. Re-install coil fi lters to original positions.

3.Have a qualifi ed serviceman inspect all furnace components and fi eld wiring and clean and service heating system as needed. If this furnace was installed with aluminum power supply wiring, have ser- viceman periodically check all connections to prevent possible equipment failure and/or fi re hazard.
