INTRODUCTION

LGR (low-grain refrigerant) dehumidifiers utilize an
internal pre-cooling system to boost water removal
efficiency. LGR units can continue to remove moisture in
drier environments where conventional refrigerants
cannot.

IMPORTANT: Damage to IEC receptacle or
dehumidifier resulting from improper removal
of the power cord is not covered by warranty.
The IEC power cord is a wear item and is not

OPERATING YOUR DEHUMIDIFIER
Set unit upright

NOTICE: Transporting or storing the unit in a
horizontal position is not recommended. When the
machine is placed in a horizontal position, the oil
from the compressor can flow into the refrigerant
coils and reduce the ability of the dehumidifier to
function and possibly damage the unit. If the unit
has been placed in a horizontal position, set it
upright and let it stand for at least 30 minutes before
turning it on.

Positioning a Dehumidifier

For best results, operate your dehumidifiers in an
enclosed area. Close all doors and windows that

open to the outside to maximize the unit’s water

removal efficiency. Place your dehumidifier away
from obstructions, and keep it away from anything

that could block airflow into and out of the unit. For
more information, contact your Dri-Eaz distributor.

Set up drain hose

This unit automatically pumps out water on a regular
basis. The condensate pump connects to a plastic
drainage hose that is located in the pocket on the side of
the unit. This hose is equipped with a quick-connect
fitting for quick attachment to the provided drain hose.
Unwrap the entire hose and place the unattached end in
a sink, drain, bucket or outdoors – anywhere that water
can drain out safely. If you use a bucket or other
container for water collection, check it regularly to
prevent overflows.

NOTICE: Uncoil and straighten the entire drain hose. Do
not leave any part of the hose coiled on the unit and do
not place the end of the hose higher than 20 ft. (6 m)
above the bottom of the unit. Also check for kinks or

07-01776M F412 2 Legend Brands

other obstructions that might restrict the flow of water.
Obstructions may cause a water backup and result in
overflows.

Plug in electrical cord

The dehumidifier should be plugged into a GFCI-

protected 120 volt outlet rated for at least 15 amps.
Remove the cord from its storage pocket and uncoil it.
Always plug the cord firmly into the unit first, and then
plug the other end into a suitable outlet.

AT THE END OF THE JOB

To reduce the possibility of drips when moving the
unit, follow these additional steps to ensure that all
water is removed from the unit.

NOTICE: To ensure all water is removed from the
dehumidifier, the unit will complete the defrost cycle
even if the unit is turned off. If the unit is unplugged
during the defrost cycle, excessive water may
accumulate in the unit and may drip out when you move
the unit. If the defrost cycle is interrupted in this way,
note that the unit will display the message POWER
FAILURE the next time it is powered up. To clear the
message, press the MENU SELECTION key.

NOTICE: To ensure the condensate tank empties
completely while purging, make sure the unit is placed
upright on a horizontal surface.

1. Do not turn unit off or move it until it has returned
to normal operating mode. To confirm unit status,
review the control panel. The control panel will
display one of the following messages:

Defrost in progress:

---

DEFROST XX

Display mode when unit is in defrost mode. XX indicates
the seconds remaining on the defrost cycle.

Shutdown sequence

WAIT FOR

DEFROST XX

Display mode when unit in defrost and unit is powered
down (shut off by user). Unit will complete the defrost
cycle to remove any built-up ice then purge the pump.
XX indicates the seconds remaining on the defrost cycle.

Drying sequence

WAIT FOR

UNIT DRYING XXX

Display mode when unit not in defrost and unit is
powered down (shut off by user). Unit will complete the 5
minute drying cycle then purge the pump. XX indicates
the seconds remaining on the drying cycle.

has returned to normal mode. You may now procede to
step 2.

2. Gently rock the machine to ensure any water
remaining on interior surfaces falls into the sump
area.

3. Press the PURGE key. When the purge cycle is
complete, turn the unit off.

4. Remove the external drain hose, drain it carefully,
coil it and secure it with one of the straps provided
on the side of the unit.

TRANSPORTATION AND STORAGE

IMPORTANT: Before moving, transporting or
storing, purge unit and stow hose and power cord as

described in the “At the End of the Job” section

above.
NOTICE: Handle the unit carefully. Do not drop, throw or

place the unit where it could fall. Rough treatment can
damage the dehumidifier and may create a hazardous
condition or void the warranty.

 Do not expose the control panel to moisture, snow

or rain.

 Store and transport securely to avoid any damaging

impact to internal parts.

 Secure during transport to prevent sliding and

possible injury to vehicle occupants.

 Do not transport or store the unit on its front, sides or

back. This will help to prevent any remaining moisture
from escaping from the unit or flowing into areas
outside the sump.

Special tip for transporting on stairs:

Before transporting unit on stairs, follow these additional
steps to ensure that all water is removed from the unit:

1. Turn the unit off after a defrost cycle has been
completed. Gently rock the upright machine on its
wheels to ensure any water remaining on interior
surfaces falls into the sump area.

2. Press the PURGE key. When the purge cycle is
complete, turn the unit off.

3. Remove the external drain hose, drain it carefully, and
return it to the pocket provided on the side of the unit.

4. IMPORTANT: Remove power cord from base of
unit, coil it neatly, and place it in the cord storage
pocket. This will prevent the cord from catching on
the stairs and possibly damaging the cord.

dust accumulation is visible. In normal use, dust can
accumulate and can restrict airflow, reducing
performance and causing the unit to overheat. See

“Disassembling the unit to clean coils and the heat
exchange block,” below.

To maintain appearance, wipe interior and exterior
surfaces with a damp cloth. For deep cleaning and a
lasting, protective shine, use a similar automotive interior
treatment.

As Needed

Clean Pump Check Valve and Basin. If the unit

displays the message “ER9 PUMP BLOCKED PUMP &
HOSE”, the pump check valve and pump basin may

need to be cleaned. This requires removal of the back
cover.
