Electrical
A 300 mm power cord is provided for use with a standard grounded outlet. It is also possible
to hard wire the unit, if necessary. Simply remove the electrical cover plate from the back of
the unit, remove the cord, and connect the hard wiring. All state and national electrical
codes must be adhered to for proper unit operation and warranty compliance.
Optional Condensate Pump:
If desired, condensate from the unit can be drained into a remote condensate pump
(provided in end use). If the condensate pump has a normally open safety switch, the safety
switch can be connected to the dehumidifier. This will allow the safety switch to shut off the
dehumidifier if it detects a problem. The wiring connections for the remote condensate pump
are located on the left hand side of the electrical compartment on the back of the
dehumidifier. Connect the red and black wires on the dehumidifier to the Normally Open
Pump Safety switch.

INSTRUCTIONS FOR USE
ON/OFF Control
Plug the unit in and the display will show the current room relative humidity. Press the on /
off button, and the machine will beep twice indicating it is ready for automatic service. If the
humidity is below set point, it will remain in standby condition. If the humidity is above set
point, the unit will turn on and begin to remove moisture from the room. Press the on/off
button again, and a single beep will indicate that the unit is turning off. No room conditioning
will occur until the unit is turned on again.
Setting the Humidity Level
Press the button to set the indoor humidity. The humidity display will shift from displaying
the actual room humidity level to the current set point. The humidity can be in 5%
increments from 30%-90%. Pressing the button increases set point by 5% until you reach
90%, then rolls over to 30% and increases from there.
