Apply power to TrueDRY DR65. Turn the humidity control to a low RH% level to initiate a dehumidification
call. Confirm that the TrueDRY DR65 compressor and fan turn on. The furnace blower will also turn on to
circulate air. This will take up to two minutes. Be sure to turn the control to the desired RH% or to Off when
checkout is complete. Turning the humidity control to Off will turn TrueDRY DR65 off.
