dehumidifier is in defrost cycle. During this

Defrost Cycle

When ice builds up on the coils, a thermistor activates the elec-
tronic control and defrost light. The compressor is turned off by
the thermistor temperature measurement. The blower will contin-
ue to run, causing air to flow through the evaporator coil and melt
the ice. When the ice is melted, the thermistor will end the defrost
cycle and the compressor will be started.

Disconnect dehumidifier from power supply. The hour meter uses
a battery backup for display when the dehumidifier is unplugged
and the hour button is depressed. To change the battery, it is nec-
essary to remove the four (4) screws from the control panel.
Disconnect the old battery and replace with new battery. Replace
control panel and screws. Do not overtighten screws.

Electrical Requirements

For 115V operation, a common grounded outlet on a 15
amp circuit is required. If used in a wet area, a ground fault
interrupter (GFI) is required.

Built in Electrical Safety

For your safety and protection this appliance is manufactured
with a grounded plug on its power cord. The power cord
must be plugged into a properly grounded receptacle. If a
grounded receptacle does not exist, have one installed by a
certified electrician. Do not cut or remove the grounding
prong on the power cord plug if equipped. We recommend
that this electrical circuit/receptacle operate under a
separate breaker or fuse.
If an extension cord is required, it must have a minimum of
14 gauge conductors if 25 feet long or less and 12 gauge
conductors if greater than 25 feet long.

WARNING

Limitations of Use

Temperature: 4°C to 35°C (40°F to 95°F)
Relative Humidity: 20 to 80%

Water Removal

The dehumidifier is equipped with an internal condensate
pump to remove the water that is collected from the air. This
allows the water to be pumped 20 feet with the attached
hose. If the water needs to be pumped more than 20 feet
above the unit, a second pump must be added to relay the
water. The condensate pump automatically purges for 20
seconds every four minutes.

OPERATION

Place dehumidifier inside area to be dried. Make sure all
windows and doors are closed to the outside and seal off the
wet area from any unaffected areas. Route condensate hose
into a drain, or a very large container. Press the On/Off
button (Fig. 1) to activate the dehumidifier.

Power Button (Fig. 1)

The dehumidifier is turned on or off by
pressing the power button. When the
dehumidifier is started, the hour meter
will display the cumulative hours.

Defrost Cycle

When ice builds up on the coils, a thermistor activates the
electronic control and defrost light. The compressor is turned
off by the thermistor temperature measurement. The blower will
continue to run, causing air to flow through the evaporator coil
and melt the ice. When the ice is melted, the thermistor will end
the defrost cycle and the compressor will
be started.

Defrost Indicator (Fig. 5)

The defrost indicator will light to indicate
the dehumidifier is in defrost cycle. During
this period, the compressor is not running.

MAINTENANCE

Storage

Freezing temperatures and biological growth must be consid­ered before storing the dehumidifier. The dehumidifier should
be flushed with a biofungicide before storing. When storing
the unit, ensure that water has been removed from the res­ervoir and hose. This will prevent damage caused by freezing
temperatures and to prevent biological growth. Use the
pump purge button to remove water and biofungicide chemi­cals from the dehumidifier.

Stacking (Fig. 9)

The dehumidifiers can be stacked on top of each other. The
wheels from the upper unit must be resting in the cradle of
the lower unit. DO NOT STACK MORE THAN TWO HIGH.

The Unit is NOT working:

• Why do you believe the dehumidifier is not working?

• Is the power ON?

• Has the breaker tripped? – Reset breaker

• If in a wet area, is the unit plugged into a GFI protected cir-

cuit? – Excessive moisture will trip GFI. Remove from area.

• Is the unit being run off a generator? - Check output does
not fluctuate as the unit will not operate at low voltage.

• If using an extension cord - Is the cord of the correct
gauge for the distance run? (14 AWG up to 25’ and 12
AWG over 25’). Note: Verify voltage while unit is starting.
Start up will cause the highest current draw and largest
voltage drop. Even if plugged directly to outlet there can
be a significant voltage drop. Never assume the voltage is
ok without verifying.

• Is the unit draining? – Check the condensate receptacle.
If full, the float is up and the unit will not operate – drain
receptacle.
