i. If the air temperature is below 80°F, an even coating of
frost should cover the entire evaporator coil
ii. If the air temperature is above 80°F, frost and/or droplets
of condensed water should cover the entire
evaporator coil.
F. After continuous running time of approximately 55 minutes, the
unit will enter “Hot Gas” defrost mode for 5 minutes and then
automatically return to normal operation.
When the unit is defrosting, the % Relative Humidity displayed on the
digital controller may increase as a result of the ice / frost melting. This
is quite normal and the display will return to its normal reading when the
unit returns to dehumidifying mode. (Fan running)
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.
Discharge Pump
The pump works automatically and periodically pumps away collected
moisture to a drain or container. The pump is capable of discharging water to
a vertical height of 20ft.
Warnings.
• 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 three minutes before
restarting.
CAUTION:
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT LEAST FIVE
MINUTES BEFORE RESTARTING.
