Warranty Registration
Congratulations on purchasing a new AirWerx 90X Dehumidifier. Your new dehumidifier comes with an
extensive warranty plan. To register, simply fill in and return the warranty card provided in your
dehumidifier box.
Be sure to note your dehumidifier serial number as you will need it for registration.
Safety Notes
The AirWerx Series Dehumidifier must always be connected using a grounded electrical connection
(as required for all electrical appliances ). If non-grounded wiring is used, all Iiability reverts to the
owner and the warranty is voided.
AirWerx Dehumidifiers should only be maintained and repaired by a qualified technician.
AirWerx Dehumidifiers are only intended for operation when oriented with the unit sitting on its feet and
level. Operating the unit in any other orientation could allow water to flood electrical components.
Always unplug dehumidifier before moving it to another location.
If there is a chance that water flooded the dehumidifier, it should be opened and allowed to dry
thoroughly before reconnecting to electrical power and restarting.
To ensure proper operation, neither the inlet nor discharge should be positioned against a wall. The
inlet requires a minimum of 12" clearance and the discharge requires a minimum of 36" clearance.
The best option for proper diffusion of air throughout the room is to have the discharge blowing away
from a wall and the inlet pulling air in parallel to a wall.
Do not insert your fingers or any object into the inlet or discharge.
All work on the dehumidifier should be done with the unit "off" and unplugged.
Do not use water to clean the exterior. To clean unit, unplug from power, then use a damp cloth to wipe
the exterior.
Do not stand on the machine or use it as a device to hang clothes.

Electrical Supply
3
Power Supply: 220 V, 50 Hz AC, Single Phase
Outlet Requirement: 3-Prong, GFI
Circuit Protector: 15 Amp
WARNING: 120 Volts AC may cause serious injury from electric shock.
To reduce the risk of injury:
1. Disconnect electrical power before servicing.
2. Only plug unit into grounded electrical circuit.
3. Do not use an extension cord.
4. Do not use a plug adapter.
Principle of Operation
The AirWerx Series Dehumidifier utilizes its integral humidistat to monitor the conditioned space. When
the relative humidity goes above the selected set point, the dehumidifier will energize. Air is drawn
across an evaporator coil, which is cooler than the dew point of air. This means moisture will condense
out of the air. The air is then reheated through the condenser coil and distributed back into the room.
Step #1: Place dehumidifier on a level surface.
Do not place unit directly on vapor barrier. For example, use blocks or pavers to create a level surface.
If the unit is handled in such a manner that the compressor did not remain in the upright position, you will
need to place it on a level surface and wait a minimum of 2 hours before turning the unit "on".
Installation
The area to be controlled should be sealed with a vapor barrier. If the unit is installed in a crawlspace, all
vents should be sealed.
WARNING: Do not install your dehumidifier in a corrosive environment. Some liquid vapor barriers
dry via "solvent evaporation". Always make sure that barrier is completely dry and area is throughly
ventilated before installing dehumidifier.

Key Functions
1. Power Key
· Use this button to turn the dehumidifier on and off. Press once to turn the machine on. You will
hear two beeps and the light will illuminate red. Press the power button a second time and you
will hear one beep as the machine shuts down. Note that there is a one minute fan delay on
shutdown.
2. Arrow Buttons
· Use the up and down arrow buttons to set the desired humidity setpoint on the display screen.
The setpoint can be any number between 36-90%. Creating a setpoint means that when the
indoor humidity is lower than the set point, the machine will stop automatically. Conversely, when
the indoor humidity is higher than the set level, the unit will operate.
NOTE: The humidity levels displayed are approximate only
3. Continuous Mode
· To switch into continuous mode, set the humidity below 36%. At this point the Cont. light
should illuminate green on the display board to indicate you have successfully switched to
continuous mode. The display screen will show "CO”.
· When set to continuous, the dehumidifier will run constantly, regardless of the humidity level. To
stop the dehumidifier from running, turn the unit off or switch back to normal humidistat operation.
To switch back to normal humidistat operation, simply move the setpoint above 36%.
4. Central Control
· This mode is not applicable on the AirWerx 90X.
(+/-5%)
Step #2: Set Up Drain Line
The included drain line attaches to unit via a compression type fitting on the discharge end of the unit. To
attach drain line, remove the compression nut and slide it over the end of the house to be attached to
unit. Side compression nut side of house over the insert on the compression fitting completely. Tighten
compression nut.

5. Manual Drain Button
· For extended storage or movement of the machine, press the "Drain" button to remove water
from the integral pump’s reservoir.
6. Pump Trouble Warning
· When the pump reservoir water level is too high, the high water sensor will activate to prevent
overflow. When this occurs, the dehumidifier will stop the compressor automatically and the display will
show "E4" error. After a 1 minute delay, the fan motor will turn off and the machine will not operate until
the problem is resolved. To reset the unit after an “E4" error, check the pump to verify it is functioning,
then unplug the unit for two minutes.
7.Auxillary Terminals A5/A6
·The A5/A6 on the terminal strip can be used as a safety switch for external condensate pumps. It
should be set to N/O (normally open) at the dehumidifier. If an E4 error codes, switch the wiring to N/C
(normally closed).

AirWerx Dehumidifiers can be controlled using an optional remote accessory. The AirWerx Remote
Control connects to your Airwerx Series Dehumidifier via a 25' CAT 5 cable. The remote control contains
an integrated sensor which gives you multiple options for remotely controlling your unit, in addition to
monitoring the conditions surrounding the dehumidifier.
One application for the remote control is to install the dehumidifier in one room with the conditioned air
ducted into a second room that contains the remote. For example, the dehumidifier could be installed in a
laundry room and ducted into a living room. The remote would then be mounted in the living room so the
remote sensor can control the humidity and provide easy controls for the user.
Another useful application for the remote control is if the dehumidifier is in area that's difficult to access on
a regular basis. For instance, if your dehumidifier is installed in your crawl space, the remote could be
mounted in your living space or garage. This provides you with an easy way to monitor the dehumidifier.
