Operation - EIP CD425 Owner's Manual

The operation of the dehumidifier is to remove moisture from the air by having
it condense on the cold tubes of the evaporator coil. The air then passes over
the hot condenser coil and returns to the conditioned space slightly warmer
and dryer than when it entered the dehumidifier unit. To concentrate drying all
doors and windows should be kept closed.
Test for Correct Operation
DO NOT RUN THE MACHINE WITHOUT THE COVERS IN PLACE FOR ANY
LONGER THAN NECESSARY. DO NOT REMOVE/REPLACE THE COVERS
1. After unpacking connect the unit to a 380/415V, 3Ph, 50Hz – 4 wire power
supply
2. Switch the machine to the on position and check for correct fan rotation.
(Air blows out of the top of the machine).
3. Check dehumidification process:
a) Remove front cover
b) Check actual relative humidity inside the area
c) Set humidity control to a lower value than the actual relative
humidity
d) After approximately 6 minutes check the compressor is running
e) Leave the machine to run for 15 minutes. (NOTE: ensure that
the set humidity, see c) above, is set very low as the
compressor will switch off when the actual RH coincides with the
set point)
f) Observe the evaporator coils
i)
ii)
4. Leave the unit to run for a further 27 minutes, after which the unit should
go through a 4 minute defrost cycle.
During the defrost cycle the defrost solenoid valve is energized and a
warming of the evaporator coil can be felt.
If after carrying out the above checks the unit does not appear to function
correctly, refer to your supplier.

OPERATION

WARNING:
WITH THE POWER ON.
If the air temperature is below 20° C, an even coating of
ice should cover the entire evaporator coil
If the temperature is above 20° C, droplets of condensed
water should cover the entire evaporator coil.
