The CD425 is a self contained low temperature dehumidifier. All electrical contactors, overloads, etc, are housed in an electrical box built inside the unit. The unit is equipped with a defrost valve which energises every 42 minutes to clear any ice formation on the evaporator coils.
Connect the outlet from the drain tray (located behind the front grille and under the evaporator coils) to a permanent drain. Please ensure that the drainage does not rise above the level of the CD425’s drain tray. Failure to observe this requirement will result in internal flooding of the dehumidifier unit.
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. CD425 OWNERS MANUAL...
