AIR FILTER
The air filter should be cleaned as often as necessary to prevent
restriction of air flow (every three months under normal conditions).
Always replace the filter with the same type as originally furnished.
BLOWER MOTOR
The Variable speed motor has sealed bearings and routine oiling is
not required or possible. The motor may be wiped down with a cloth or
blown out to remove any accumulated dirt and dust to help the motor cool.
To remove the blower and motor:
-
turn off all power to the air handler.
-
Disconnect the thermostat wiring from the 5 position terminal strip
on the blower mounted electrical box.
-
Unplug the power supply MOLEX terminal from the top of the
blower mounted electrical box.
-
Remove the two blower mount screws and slide blower and motor
from the unit.
CIRCULATION PUMP REPLACEMENT
Disconnect electrical power before servicing the unit.
To replace the circulating pump, close the isolation valves and relieve the
water pressure from within the heating loop. Remove the four hex head
screws that secure the pump head to its volute. Disconnect the pump’s
115VAC power lines from within the electrical control box and remove
the pump from the unit.
Reverse the above steps for re-assembly of the pump. Refer to initial
start-up procedure for instructions regarding purging air from the system.
