Frost Control. In some cases of prolonged operation or if the conditioned space is relatively cool, frost will accumulate on the coil. Ice may eventually cover the coil, block the air flow and stop proper operation. If the coil becomes unacceptably cold for at least ten minutes, a sensor mounted on the coil will stop the compressor. To prevent frost build-up beyond an acceptable level, the fan will continue to operate to melt any accumulated ice.
Dampers. Optional dampers may be installed in the outlet duct, inlet duct or in an outside air duct. These dampers must be a fullflow motorized type. Do not use any type of pressure operated damper as unacceptable pressure drop will affect unit operation. All dampers must be installed in compliance with the damper manufacturer’s recommendations and be insulated and sealed per the section on ducting above.

Damper Connection. If an optional damper(s) is used in the discharge/return duct, this may be controlled by the dehumidifier. See “Unit Connection Diagram - Independent Operation”, above for connection details. When connected as shown in the above diagram, the dehumidifier provides only the switching interface for the damper(s). Power for these devices must be provided with a separate transformer (not provided), not from the transformer located in the dehumidifier.
Unit Connection Diagram – Dependent Operation Initial Set Up Turn power to the dehumidifier on. Adjust the set point knob to approximately 60% relative humidity. For wall-controls, adjust the unit-mounted control to its minimum relative humidity (RH) setting and set the wall-mounted dehumidistat to a desired level. It is recommended that it first be set to approximately 60% RH and then adjusted, no sooner than 24 hours later, to a higher or lower set point as desired.
Dimensions Troubleshooting PROBLEM • • • Dehumidifier will not run. • • • POSSIBLE SOLUTION Verify there is power to the unit. Check that any disconnect switch is in the ON position. Check that the circuit breaker is not tripped (a separate 15 amp circuit breaker is recommended). Verify the dehumidistat is not in the OFF position. Verify low voltage wiring between heating and air conditioning system and dehumidifier is correct. Unit door switch is not mechanically actuated due to loose door.
