Model
7.0 Annual maintenance
This electric furnace requires very little maintenance. Nonetheless the following points should be checked annually:
REPLACE the air filter. The model used is a standard 20" X 20" X 1" thick paper air filter found at any hardware
store.
Verify the operation of the unit by having the thermostat call for heat. Re‐verify the temperature differential
(Delta T) between the inlet and outlet plenums. A difference from the initial installation results can be a clue to
obstruction problems in the duct system if the delta T is higher but could also be a clue that one or more heating
elements are faulty if the delta T is lower.
The blower motor DOES NOT require lubrication.
