WARNING!
ELECTRICAL SHOCK HAZARD: Electrical power
must be present to perform some tests. These tests
should be performed by a qualied service person.
Unit Test to Determine Problem:
1. Detach eld control wiring connecons from main unit.
2. Connect the yellow and brown pigtails from the main
unit together; only the fan should run. Disconnect the
wires.
3. Connect the yellow and blue pigtails from the main unit
together; the compressor and fan should run.
4. If these tests work, the main unit is working properly.
You should check the control panel and eld control
wiring for problems next.
NOTE: Refrigeration systems should ONLY
be serviced by a qualied service technician.
If you need additional information, consult
Technical Support at 1-855-239-2665.
Refrigerant Charging
If the refrigerant charge is lost due to service or a leak,
a new charge must be accurately weighed in. If any of
the old charge is le in the system, it must be recovered
before weighing in the new charge. Refer to the unit
nameplate for the correct charge weight and
refrigerant type.
Compressor/Capacitor Replacement
This compressor is equipped with a two terminal external
overload and a run capacitor. The compressor is controlled
by a dedicated relay.
Remote Controls
The DV090 dehumidier is controlled by digital controls
that are remote from the unit. You may or may not have
the devices listed below depending on the model of the
control you purchased. If the dehumidier fails to oper-
ate as desired, always check the sengs of the controls
to insure that they are correct. Check that the controls
are receiving 24VAC from the dehumidier. Check the
connecons between the dehumidier, the control,
and the eld control wiring.
5. Remove the control panel from the mounng box
and detach it from the eld installed control wiring.
Connect the blue, yellow, and green wires from the
control panel directly to the corresponding colored
pigtails on the main unit. Leave the violet, white and
red wires disconnected!
6. Turn on the fan switch; the fan should run. Turn o
the fan switch.
7. Turn on the humidity control; the compressor and
fan should run.
8. If these tests work, the problem is most likely in the
eld control wiring.
