1) Maintenance: 

At the beginning of each season, the air handler should be serviced 

by a qualified installer or service technician.

• Filter: This filter should be inspected and replaced as required.

• Coils: the heating and air conditioning coils should not require 

regular maintenance IF a regular filter maintenance schedule is 

followed. In the event, the filter is damaged or plugged and dust 

has fouled the coil, replace the filter and carefully vacuum the 

heating and/or A/C coil.

• Circulator: The circulating pump is water lubricated and should 

not require regular maintenance. The system control has a pump 

exercise function during prolonged periods of no heat to avoid 

seizing.

• Blower: The blower requires regular cleaning due to the build-up 

of dust. In the event the filter is damaged, refer page 52 ~ 53 for 

disassembly. 

2) Checking Temperature Sensors:

1. Remove cables from the temperature sensor.

2. Check the sensor resistance and compare the actual values with 

the curve on the chart.

3. Replacement of a sensor is required in the case of severe 

deviation.
