Warranty Registration
Congratulations on purchasing a new AirWerx 90 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.
Do not insert your fingers or any object into the inlet or discharge.
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.
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.
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.
Always unplug dehumidifier before moving.
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.
All work on the dehumidifier should be done with the unit "off" and unplugged.
Do not stand on the machine or use it as a device to hang clothes.
Do not use water to clean the exterior. To clean unit, unplug from power, then use a damp cloth to
wipe the exterior.

Identification
For future reference, write down the model, serial number, and date of purchase for your dehumidifier.
This is extremely helpful if you need to seek assistance in the future. The data label on the side of
your unit has the key characteristics of your specific unit.

Electrical Supply
3
Power Supply: 115 V, 60 Hz AC, Single Phase
Outlet Requirement: 3-Prong, GFI
Circuit Protector: 15 Amp
To reduce the risk of injury:
1. Disconnect electrical power before servicing.
WARNING: 240 Volts AC may cause serious injury from electric shock.
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.
Installation
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.
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.

4
NOTE: Do not place directly on vapor barrier. Elevation is required to allow the condensate water to
drain via gravity.
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".
Step #1: Place dehumidifier on a level surface.
Step #2: Set Up Drain Line
The drain line should be routed to a suitable drain on the outside. It must flow down to the drain without
any loops, dips, or valleys.
1. Cut a piece of 3/4" OD PVC that is approx. 6" long.
2. Insert PVC into a 3/4" elbow, then attach to a 3/4" OD length of PVC to drain.
(Note: Keep the length of PVC drain pipe to a minimum).
3. Insert the open end of the tubing into the 3/4" pipe so that it does not extend into the elbow fitting. For
proper flow, a minimum downward slope of 1" per 10' run is required. ( Note: If a proper downward
angle is not possible, then it is recommended to use an AirWerx 90 which includes an integrated pump
or utilize an external condensate pump).
5. Always test the drain before leaving the installation area.
4. Support the PVC tubing so that it maintains a smooth downward flow to drain.
Recommended Drain Option-Transition to PVC Pipe
Drain Tube - 12 inches Long. 12mm OD.
Step #3: Plug unit into 15 amp grounded circuit.

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.
NOTE: Symbols indicated below will only appear when the dehunidifier is powered on.
Remote Control Instructions
1.Humidity Display Screen
The display screen has two functions:
2.Power Indicator Light
3.Continuous Mode/autodefrost Light

When this light iluminates green, it indicates that the dehumidifer is set to continuous
operation mode.
1. When the unit is powered on, it shows the humidity of the space.
2. While setting the desired humidity level, the screen wil show the set humidity. After a brief
delay,the display will revert to current humidity level.
When the light glows red, it means the unit is in auto defrost mode and clearing the
evaporator coil of any ice buildup.
When the compressor light glows red, it indicates the compressor has been initiated but is
currenty warming up.
Once the compressor light switches to green, it indicates the compressor is in working
status.
