Maintenance

Air Filter (Fig. 7)

The air filter should be checked regularly. Operating the dehu-

midifier with a clogged filter will reduce efficiency. The filter can be

vacuum cleaned to remove dust. To access the filter media, slide

the filter frame up until it clears the dehumidifier cabinet. Remove

the filter media from behind the frame and vacuum. Reverse pro-

cedure to re-install the filter and frame into the dehumidifier.

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. 

External Cleaning

Use  a  non-flammable  mild,  non-abrasive  soap  and  clean

water solution to clean the dehumidifier. Wipe dry.

Internal Cleaning

Disconnect dehumidifier from power supply. 

Light cleaning:

Remove the air filter and spray evaporator

coil  with  water.Remove  the  two  upper  screws  from  the  front

hood. 

Heavy cleaning:

Remove two upper screws from front hood.

Open  hood.  Spray  water  at  coils.  Close  hood  and  replace

screws. (Fig. 8)

Electrical Shock Hazard

Plug into a grounded 3 prong outlet.
Do not remove ground prong.
Do not use an adapter.

WARNING

Disconnect power supply before cleaning.
Failure to follow these instructions can result in death,

fire, or electrical shock.

Venting / Ducting (Fig. 6)

Twin  rear  outlets  can  accommo-

date two individual 5” ducts or one

10”  lay  flat  duct  to  be  attached.

This allows for warm dry air to be

directed into different areas.

Service

A qualified refrigeration technician must service all refriger-

ant leaks. 
WARNING: The dehumidifier uses a high pressure refrigerant

system and high voltage circuitry which could present a health

hazard resulting in death, serious bodily injury, and/or property

damage. Only qualified service people should service this unit.

CAUTION:

Do not operate unit without the front hood secured in

place.
The serial data plate is located on the underside of the dehumid-

ifier. For service information contact 1-800-565-3548.

Troubleshooting

Service

A qualified refrigeration technician must service all refrigerant leaks.

The Unit is NOT working:

•  Has the breaker tripped? – Reset breaker
•  If in a wet area, is the unit plugged into a GFI protected circuit? – 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.

The unit shuts down and displays an error code. 

ER 1: Overflow switch remaining closed for >2 minutes.
•  Plugged or kinked drain hose – Remove obstruction
•  Bad connection in pump circuit – Check connections
•  Defective condensate pump – Replace

ER 2: Internal pressure switch indicates refrigerant pressure is too high.
•  Air filter is dirty or plugged – Clean or replace air filter
•  The coil is dirty – Clean the coil
•  Loose or faulty electrical connections to pressure switch – check 

connections

•  Fan is not working – Replace
•  Defective pressure switch – replace

The unit continually ices up: Note that some ice buildup on the evaporator coil 
is normal but airflow should not be blocked.

•  Is warm air blowing out the back of the unit? - No warm air, ambient 

temperature may be too low. Raise temperature with supplementary 
source.

•  Is the air filter clean and airflow unobstructed? – Clean filter. Unit should 

have a minimum of 10” clearance all around it.

•  Dirty evaporator coil? – Clean coil.

Unit moves some water but not as much as expected:

•  Air filter dirty or airflow obstructed - Unit should have a minimum of 10” 

clearance all around it. Clean air filter and ensure adequate airflow/space 
around unit.

•  Evaporator coil dirty – Clean coil.
•  Restrictive or kinked exhaust ducting (if used) – Straighten out ducting.

Fan does not run. Compressor runs briefly but cycles on/off:

•  Loose connection in fan circuit – Check connections.
•  Fan obstructed and not turning – Remove obstruction.
•  Defective fan – Replace fan.
•  Defective control board – Replace control board.

Cleaning

Disconnect power supply before cleaning
Failure to follow these instructions can result in death, fire, or electrical shock

External Cleaning

Use a non-flammable mild, non-abrasive soap and water solution. Wipe dry.

Internal Cleaning

Disconnect dehumidifier from power supply.

Light cleaning: Remove the air filter and spray evaporator coil with water. 

Heavy cleaning: Remove two upper screws from front hood. Open hood. Spray water at coils. Close 
hood and replace screws. (figure 8)

Care must be taken to insure coil fins are not damaged, as damaged fins can restrict airflow 
and reduce the unit's ability to produce water. 

Storage

Freezing temperatures and biological growth must be considered before storing the dehumidifier. To 
prevent the biological growth, spray an evaporator cleaner on the coils and rinse into the drainage 
system. You must also purge the excess liquid from the pump using the manual purge function to 
prevent issues with freezing storage environments.
