DRAIN PAN VALVE

During the cooling mode of operation, condensate which

collects in the drain pan is picked up by the condenser fan

blade and sprayed onto the condenser coil. This assists

in cooling the refrigerant plus evaporating the water.

During the heating mode of operation, it is necessary that

water be removed to prevent it from freezing during cold

outside temperatures. This could cause the condenser

fan blade to freeze in the accumulated water and prevent

it from turning.

To provide a means of draining this water, a bellows type

drain valve is installed over a drain opening in the base

pan.

This valve is temperature sensitive and will open when

the outside temperature reaches 40°F. The valve will

close gradually as the temperature rises above 40°F to

fully close at 60°F.

TESTING THE HEATING ELEMENTS AND

LIMIT SWITCHES

Testing of the heating elements can be made with an

ohmmeter or continuity tester across the terminals after

the power wires have been removed. Test the limit switch

for continuity across its input and output terminals.Test

below the limit switch’s reset temperature.

HEATER ELEMENTS AND LIMIT SWITCHES’

SPECIFICATIONS

All heat pumps and electric heat models are equipped

with a heating element and a limit switch (bimetal ther-

mostat). The limit is in series with the element and will

interrupt the power at a designed temperature.

Should the blower motor fail, lter become clogged or air-

ow be restricted etc., the high limit switch will open and

interrupt the power to the heater before reaching an un-

safe temperature condition.
