OPERATION
The following procedures should be followed to test the RM4500 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 15 Amp electrical outlet.
2.
Check dehumidification process as follows:
A.
Place unit on a level surface.
B.
Start up unit by switching to “I”.
C. Check that the compressor is running.
D.
Leave the machine running for 15 minutes.
E. Observe the evaporator coils through the front grille, to confirm
frost formation.
i. If the air temperature is below 78
°
F, an even coating of frost
should cover the entire evaporator coil.
ii. If the air temperature is above 78
°
F, frost and/or droplets of
condensed water should cover the entire evaporator coil.
F.
When the unit is operated in ambient of less than 59°F, a
defrost cycle should occur approximately 20 mins. The exact
time is impossible to predict as the unit is fitted with a
temperature sensitive defrost control.
If, after carrying out the above procedures, the unit does not appear to
function properly, refer to the
Trouble Shooting
section, which follows,
or contact the Factory Service Center.
After using the RM4500, turn it off for five minutes to allow the condensate on
the coils to drain into the pump reservoir, then press the momentary pump
purge switch for twenty to thirty seconds to evacuate the water from the pump
reservoir.
CAUTION:
DO NOT REMOVE COVERS WHEN UNIT IS IN OPERATION
CAUTION:
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT
LEAST FIVE MINUTES BEFORE RESTARTING.
