baseaire AirWerx 90 198 Pints Energy Star Crawl Space Commercial Dehumidifier Instruction Manual

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 liability 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.
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 6′ clearance and the discharge requires a minimum of 6′ clearance.
For better use of the dehumidifier, both air inlet and air outlet should be facing the open area of the space.
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.

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

Power Supply: 115 V, 60 Hz AC, Single Phase
Outlet Requirement: 3-Prong, GFCI
Circuit Protector: 15 Amp

WARNING: 240 Volts AC may cause serious injury from electric shock. To reduce the risk of injury:

Disconnect electrical power before servicing.
Only plug unit into grounded electrical circuit.
Do not use an extension cord.
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

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.

Step #1: Place dehumidifier on 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”.

NOTE: Do not place directly on vapor barrier. Elevation is required to allow the condensate water to drain via gravity.

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.

Recommended Drain Option-Transition to PVC Pipe

Cut a piece of 3/4″ OD PVC that is approx. 6″ long.
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).
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 90X which includes an integrated pump or utilize an external condensate pump).
Support the PVC tubing so that it maintains a smooth downward flow to drain.
Always test the drain before leaving the installation area.

Step #3: Plug unit into 15 amp grounded circuit.

Drain Tube -12 inches Long, 12 mm OD,

Key Functions

Power Key
- Use this button to turn the dehumidifier on and off. Press once to turn the machine on. You will hear one beep and the light will illuminate green. 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,
Arrow Buttons
- Use the up and down arrow buttons to set the desired humidity setpoint on the display screen.. 88 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 sutomatically. Conversely, when the indoor humidity is higher than the set level, the unit will operate. NOTE: The humidity levels displayed are approximate only (+/-06)
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%.
Central Control
- This mode is not applicable on the AirWerx 90.
- Central Control light should off at all times when not connected to the AC
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)

Indicator Lights

Humidity Display Screen
The display screen has two functions:
When the unit is powered on, it shows the humidity of the space.
While setting the desired humidity level, the screen will show the set humidity. After a brief delay, the display will revert to the current humidity level.
Power Indicator Light
- This light indicates that the unit is properly powered on and ready to operate. Always make sure the unit is “off” prior to performing any service.
Continuous Mode / Auto Defrost Light Defrost
- When this light illuminates green, it indicates that the dehumidifier is set to continuous operation mode.
- When the light glows red, it means the unit is in auto defrost mode and clearing the evaporator coil of any ice buildup.
Compressor Light
- When the compressor light glows red, it indicates the compressor has been initiated but is currently warming up.
- Once the compressor light switches to green, it indicates the compressor is in working status.

Remote Control Instructions

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.
