Drain Pans and Interior of Unit
The inside of the unit, including drain pans (if equipped),
should be wiped clean annually with a soft cloth and mild
cleaning solution. Check the drain fittings (if equipped) to
ensure they are draining freely.
Plate Heat Exchanger
Clean the heat recovery module by removing it from the
unit and washing out the spaces between the plates using
a mild detergent. If a high pressure hose is used, avoid
causing damage to the exchanger by making sure that the
nozzle does not get too close to it.
Heaters/Air Conditioning Coils
Check the duct heaters, hot water coils and air condition-
ing coils for obstruction or build-up of dust. Check the
manual reset button on your duct heaters (if unit has elec-
tric heat). If the red buttons are released out, depress the
red button to reset the switch. If this problem persists, call
your local technician.
Dampers
Check inside dampers for obstruction and cleanliness.
Fans
Blower wheels and fan housings should be checked for
dust build-up. If excessive dust build-up exists, it will be
necessary to remove the blower assembly to clean the dust
out through the fan mouth.
To remove the supply blower, first remove the two screws
holding the blower in place, disconnect the electrical plug
and slide the blower out of the unit.
To remove the exhaust blower, the control box has to be
removed. Disconnect the electrical plugs from the control
box and remove the four screws holding it in place to
expose the exhaust blower. Remove the two wing screws
and slide the exhaust blower out.
