OPERATION
The following procedures should be followed to test the PD120 for correct operation:
1)
After unpacking, examine all external features to confirm damage-free shipment. Report all
defects and damage at once. Connect the power cable to a grounded power source.
2)
Connect the drainage outlet to a suitably sized hose and run the hose to a permanent drain.
Caution: Do not operate the machine without the covers for any longer than necessary. Do
not remove/ replace the covers when the unit is in operation.
Check dehumidification process as follows:
A.
Place unit on a level surface.
B.
Start up unit as follows:
i.Ensure fan speed selection has been chosen as mentioned in previous pages and also
that the humidistat has been wired in.
ii.Rotate humidistat control knob to fully counter clockwise, minimum setting.
iii.Plug unit into power supply and rotate humidistat knob clockwise to desired setting.
C.
Check that the compressor is running.
D.
Leave the machine running for 15 minutes.
E.
Observe the evaporator coils behind the filter on the air inlet end of the unit to confirm
frost formation.
i.If the air temperature is below 70ºF, an even coating of frost should cover the entire
evaporator coil, except for the last one or two coils.
ii.If the air temperature is about 70ºF, frost and/or droplets of condensed water should
cover the entire evaporator coil.
F.
As the drain tray fills, the condensate will automatically drain by gravity.
If after carrying out the above procedures, the unit does not appear to function properly, refer to
the Trouble Shooting section or contact the Factory Service Center.
WARNING:
•
Due to the high pressures within the refrigeration circuit, under no circumstances must direct
heat be applied to the evaporator coil in an attempt to remove the build up of ice.
•
No attempt should be made to cut open any part of the refrigeration circuit due to high
pressures and gas involved. If the unit is switched off at the mains power supply for any
reason, the unit must be allowed to stand at rest for at least five minutes before restarting.
Failure to do so may cause the unit to blow the fuses owing to the compressor due to there
being a refrigerant imbalance.
