Operation - Fantech EPD150LR Installation And Maintenance Manual

Industrial Dehumidifier
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.
an extension cord is required, it must have a minimum of 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.
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 (figure 1) to activate the dehumidifier.
Start-up Mode
The dehumidifier is turned on or off by pressing the power button (figure 1). When the dehumidifier
is started, the hour meter will briefly display the software version #, followed by the cumulative
hours.
Pressing the power button during the first minute, the unit will go into OFF Mode immediately.
Run Mode
During Run Mode the compressor is running causing the evaporator to get cold resulting in
condensate forming on the coil.
The unit will stay in run mode for variable length of time depending on the ambient conditions.
Pressing the power button (figure 1) will send the unit in shut down mode (see below)
Defrost Mode
During the defrost mode, the indicator light will turn on (figure 2), the compressor will be off and the fan
will continue to run. The pump purge will be activated automatically.
The defrost cycle runs every 45 minutes in cool ambient temperature, less often in warm ambient
temperature and the length of time in defrost will vary appropriately.
Heavy frosting on the coil can be expected during low ambient conditions and will not affect the
operation of the unit.
