Safety Information
Keep Children Away: Do not allow children to play with or
around the unit, which could result in injury. Be sure the unit
is inaccessible to children when not attended.
Keep Unit Grounded: Always operate the unit with a
grounding plug and a grounded electrical outlet. A grounding
plug is an essential safety feature that helps reduce the risk
of shock or fire.
Protect Power Cord from Damage: Never operate a unit
with a damaged power cord, as this may lead to electrical or
fire hazards. If the power supply cord is damaged, it must be
replaced by a cord of the same type and amperage rating.
Extension Cords: Extension cords must be grounded and
able to deliver the appropriate voltage to the unit.
Handle With Care: Do not drop or throw the unit. Rough
treatment can damage the components or wiring and create
a hazardous condition.
Run on Stable Surface: Always operate the unit on a sta-
ble, level surface, like the floor or a strong counter, so it can-
not fall and cause injury.
Secure During Transport: When transporting in a vehicle,
secure the unit to prevent sliding and possible injury to vehi-
cle occupants.
Keep Out of Water: Never operate the unit in pooled or
standing water, as this may create a risk of injury from elec-
trical shock. Do not store or operate outdoors. If electrical
wiring or components become wet, thoroughly dry them be-
fore using the unit.
Keep Air Intakes Clear: Do not clog or block air intakes, as
may occur if operated to close to draperies or similar materi-
als. This may cause the unit to overheat and result in a fire or
electrical hazard.
Keep Filter Clean: Always use a clean air filter. Do not allow
any material to clog the filter, as this may cause the dehu-
midifier to overheat. Do not allow oil, grease, or other con-
taminants to be drawn into the dehumidifier.
Keep Electrical Components Dry: Never allow water inside
the dehumidifier's electrical components. If these areas be-
come wet for any reason, thoroughly dry them before using
the dehumidifier.
Allow Repair Only by Authorized Service Technician: Do
not attempt to disassemble or repair the unit if you are not
qualified to do so. You may handle some maintenance and
troubleshooting, but make sure that more complex problems
are handled by an authorized service technician. For infor-
mation about authorized repair, call Dri-Eaz at (360) 757-
7776 in the US, or [phone] in the UK.
HOW TO USE DEHUMIDIFIERS
DrizAir Dehumidifiers are designed to reduce water vapor or
high humidity in a building or part of a building. The purpose
is to prevent humidity damage, and to dry out wet materials
such as carpet, carpet cushion, floors, walls, furniture, con-
tents, lumber, and structural materials.
To speed up the rate of evaporation, and dry out materials
faster, use Dri-Eaz TurboDryer airmovers. The DrizAir De-
humidifier will be needed to remove the additional water
evaporated by the TurboDryers.
Positioning Dehumidifiers
The dehumidifier must be operated in an enclosed area to
achieve best efficiency. Close all openings to other areas of
the building, like windows and doors, to prevent moist air
from mixing with the air in the drying area. Keep traffic
through doors at a minimum. This forms a closed drying
chamber.
Inside the drying chamber, air should circulate freely. Open
interior doors and operate TurboDryer airmovers to maintain
good airflow to all areas.
Place the dehumidifier where there is no restriction to air
flowing through either the inlet or the outlet. Keep away from
loose materials like curtains and drapes.
Under normal circumstances, place the dehumidifier in the
center of the room. To dry a specific area, place the dehu-
midifier so the outlet air points at the wet area and the warm,
dry air passes across it. The duct should never be closer
than three feet from the wall.
The DrizAir Dehumidifier warms the air as it removes its
moisture. In smaller rooms this can raise the temperature
substantially. Room temperatures of about 20° to 27° C (68°
to 80° F) are usually a good condition for drying. Never allow
the room temperature to exceed 38° C (100° F), because
this could damage the dehumidifier or building contents.
OPERATING INSTRUCTIONS
1. Operate the DrizAir Dehumidifier only in the upright posi-
tion. If it has been in a horizontal position for any time
over a few minutes, let it sit in the upright position for at
least 30 minutes before starting. This allows oil to drain
back into the compressor, increasing its life.
2. Plug in to a standard outlet with the correct voltage and
amperage for the unit. Push the ON switch. Listen for
proper operation of fan and compressor before leaving
the unit unattended.
3. Allow five minutes before restarting after the unit
shuts off for any reason. This will avoid damaging the
compressor.
4. If your unit has a pump, run the pump drain hose into a
sink, toilet, drain, or bucket. Make sure the hose is not
kinked. If using a bucket, check and empty the bucket

07-00212 K ©2000, 2002, 2004 Dri-Eaz Products, Inc. 2
frequently to prevent overflow.
5. Before moving the unit, make sure the pump is empty of
water. To do this, let the unit sit while OFF for 10 min-
utes, while water drains drain from the coils into the
pump. Then push the PURGE switch.
6. CAUTION: Check dehumidifier daily for correct opera-
tion. Protect floor surfaces from leakage.
Water Removal Rate
With all dehumidifiers, the rate of water removal varies with
humidity and temperature. If possible, judge the performance
of the dehumidifier by how much the humidity drops, rather
than by the volume of water being removed and deposited in
the bucket. You can roughly guess the humidity by its "feel"
on your skin, but to be accurate use a thermo-hygrometer.
To estimate how many dehumidifiers to place, see the Speci-
fications below.
How the Machine Works
DrizAir units are refrigerant dehumidifiers. They operate by
blowing moisture-laden air from the room across a cold
evaporator coil. Moisture in the air condenses on the coil,
drips off, and then is removed through a drain hose or pump.
Now warmer and drier, the air passes back into the room to
continue its work of carrying water vapor.
When a DrizAir Dehumidifier is operating at a room tempera-
ture below about 20° C (68° F), frost will normally form on
the evaporator coil. Water removal will stop temporarily.
When an automatic control built into the unit senses the ice
temperature, it initiates a defrost cycle. During this time, con-
siderable quantities of water drain from the unit. As soon as
the ice has melted, normal operation resumes.
How to Use the Touchpad Controller
The Touchpad Controller used on DrizAir dehumidifiers has
one display and four keys. The normal display messages
are:
DEHUMIDIFIER OFF
DEHUMIDIFIER ON
TOTAL HRS=00000
JOB HRS=00000
CMPRSR DELAY 60
PUMP PURGING
DEFROST ON
GET SERVICE ER01
Control Keys
ON-OFF. When the unit is first plugged in, the display
cycles through three messages: DEHUMIDIFER
OFF, TOTAL HOURS , and JOB HOURS. Press the
ON-OFF key to turn the unit on. The display often
reads CMPRSR DELAY 00, with the numeral count-
ing down from a maximum of 60 seconds to 0. At that
point the unit begins to operate and the display reads
DEHUMIDIFIER ON. (The delay prevents damage
from accidental power interruptions, where power to
the compressor stops and then starts again when
pressure in the system is still high.)
PURGE. Push this key to run the purge before tipping
the unit. This empties water from the pump reservoir
to prevent leakage. If the unit has been operating,
turn the power OFF but leave the cord plugged in for
about 10 minutes while water drips from the coil; then
press PURGE to remove residual water. The purge
also runs automatically every six minutes during op-
eration, and whenever the reservoir is full. While the
purge is running, the display reads PUMP PURGING.
DISPLAY. Press the DISPLAY key to stop the display
at DEHUMIDIFER ON or OFF, TOTAL HOURS, or
JOB HOURS, when it is cycling. Press again to make
the display cycle again.
CLEAR. To clear the JOB HOURS reading, first
press the DISPLAY key to make the display read
JOB HRS steadily. Then press the CLEAR key to re-
set the numerals to 00000. NOTE: the TOTAL
HOURS reading cannot be re-set.
Defrost On
The display will read DEFROST ON whenever the unit is in a
defrost cycle. During normal operation, frost forming on the
coils is detected by the temperature sensor, causing a de-
frost cycle to start. Dehumidification is suspended as hot gas
flows through the coils and melts the frost. At the end of the
defrost cycle, the display returns to its normal condition.
Changing Language Shown on Display
The default language is English. To change to another lan-
guage, follow these steps. (1) The unit must be unplugged
from the power outlet. Hold down the DISPLAY key while
plugging the unit in. The display now reads "ENGLISH." (2)
Press the DISPLAY key or the CLEAR key to adjust the
reading to FRANCAIS, DEUTSCH, or ESPANOL. (3) Then
unplug the unit from the power outlet, which sets the lan-
guage.
CAUTION: While in the change-language mode, pressing
other keys can change operating parameters of the unit. Do
NOT press other keys or change parameters, except when
following guidelines from the Dri-Eaz Service Department.
Error Messages
In case of certain problems, the display may show the error
message "GET SERVICE," followed by "ER01" or another
numeral. Follow these steps:
1. First, unplug the unit and then plug it back in. This may
re-set the electronics.
2. If that does not fix the problem, try the solution if one is
listed in the table below.
3. If that does not fix the problem, contact the Dri-Eaz Ser-
vice Department ( contact information above).
ER
1-2-3-5-6
Problem with the electronic control panel.
Contact Service.
ER4 Problem with temperature sensor or cable.
ER8 Problem with a touchpad key. Press and re-
lease each key several times.
ER9 Check for obstructions in pump or drain hose,
or that pump wiring is correct.
ELECTRICAL CONNECTIONS
DrizAir Dehumidifiers are designed to operate on a 230V/50
Hz electrical connection. Make sure that the electrical outlet
is grounded and that all safety precautions are taken.
MAINTENANCE
Always turn off the power before performing maintenance
procedures. All the service procedures below are to be exe-
cuted with the unit unplugged. Perform before each use or as
needed.
INSPECT ELECTRICAL SYSTEM: Inspect the electrical cord
for damage at regular intervals. Periodically, remove the
housing and inspect internal wiring for bare wires, insecure
fasteners, and discoloration. Remove and repair any dam-
aged wiring as needed. Failure to do so may lead to electri-
cal shock or a fire hazard.
PUMP TUBE: Make sure the pump tube is completely un-
wrapped and not kinked. Failure to do so can cause water to
back up in the pump and leak out. The control panel may
signal this problem by displaying “ER9.”
KEEP OUT DUST. Keep dust from drywall, demolition, and
other sources out of the coils. Failure to do so can cause the
unit to overheat, leading to compressor failure or other prob-
lems. Do not run the unit during sanding, painting or other
operations producing airborne particulate. When dust is pre-

07-00212 K ©2000, 2002, 2004 Dri-Eaz Products, Inc. 3
sent, use the optional pleated paper filter to keep more dust
out of the unit; also, inspect and clean the coils as required.
USE A CLEAN FILTER. Keep a clean filter in the unit at all
times to keep out dust. When using a foam filter, clean with a
vacuum, or wash with water and mild detergent and allow it
to dry. When using paper filters, discard the filter when visi-
bly dirty and insert a clean one.
SHINE EXTERIOR: Use a sponge and mild detergent for
regular cleaning. Do not pour or run water onto the unit or
allow water to soak the touchpad control. Bring back the
original shine with a vinyl cleaner-polish.
Periodic Maintenance (as needed)
Make sure unit is unplugged. Remove housing as needed to
permit access to interior parts.
KEEP COILS CLEAN. Dirty coils do not remove water effi-
ciently. Inspect them regularly, especially if operating in
dusty environments. Clean if they are visibly dirty.
First make sure coils are dry, then blow them clean with di-
rect compressed air from both sides of the coil. Do NOT hold
too close to the coils, as high-pressure air may fold the fins.
If sticky or oily residue remain, do a wet cleaning. Use a
squirt bottle to flush the coil with water and a little detergent.
Do NOT run a hose or pressure washer on the coils, or per-
mit water to enter the electrical compartment.
Remove dirt buildup with an aluminum evaporator coil
cleaner available from a refrigeration supply outlet. Follow
product directions carefully.
When cleaning coils, also make sure that the drain tray, drain
hose, and filter cover are free of dirt.
PUMP SYSTEM: Inspect and clean the pump system regu-
larly to maintain effective operation. Remove the four screws
holding down the pump cover. Clean the catch basin. Make
sure the float shaft operates smoothly and does not stick in
the OFF position. Use a pipe cleaner to clean the gravity
drain hose.
