OPERATION
The operation of the dehumidifier is to remove moisture from the air by having
it condense on the cool tubes of the evaporator coil. The air then passes over
the hot condenser and returns to the conditioned space slightly warmer and at
reduced moisture content. To concentrate drying all doors and windows
should be kept closed.
AIR MOVING SYSTEM:
Air is drawn in through the inlet grille at the rear of the dehumidifier (below the
handle) and over the two heat exchanges (evaporator/condenser coils) under
the influence of the axial fan, which is driven by the motor. The operation of
the fan motor is to run continuously whenever power is supplied to the
dehumidifier. The fan motor used in the dehumidifier unit is induction
protected i.e. the motor is able to take stalled current without burning out the
motor windings.
TEST FOR CORRECT OPERATION:
Remove the cover by releasing the retaining bolts and follow the test
procedure laid out below.
1. Set the adjustment humidistat to maximum
2. Switch the machine to the on position; this will result in the compressor
starting to run and the fan blade to starting to rotate.
3. When the compressor has been running for twenty minutes the coils
located above the drain tray will be evenly coated in frost. (If the
temperature is above 25ºC the coils will be covered in water).
4. After the machine has been running for approximately fifty minutes the
unit will automatically enter defrost. The defrost cycle lasts for
approximately three minutes; this will result in the frost on the coils
meeting and dripping into the drainage tray.
5. After the defrost cycle has finished the machine will return to normal
operation.
6. Ensure the condensate drains away from the machine.
WARNING:
DO NOT RUN THE MACHINE WITHOUT THE COVERS IN PLACE FOR ANY
LONGER THAN NECESSARY. DO NOT REMOVE / REPLACE THE
COVERS WITH THE POWER ON
