Installation Guide
Fresh Air Ventilation (optional)
An automatic ventilation controller and dehumidi­stat are included.
The dehumidifier removes 90 pints of water from the air per day (80F, 60% RH) while only using 6.2 Amps of electricity.
The high moisture removal capacity helps main­tain proper levels of humidity in most homes.
Dehumidification
The dehumidifier's high efficiency refrigeration system is further enhanced with a heat exchanger to achieve exceptional performance while keeping your energy costs as low as possible.
HVAC Installer: Please leave manual for homeowner.
Fresh air may be ducted to the unit and regulated using an optional fresh air ventilation controller along with a fresh air damper.

Safety Precautions
Read the installation, operation and maintenance instructions carefully before installing and
operating this device. Proper adherence to these instructions is essential to obtain maximum
benefit from your indoor air quality system.
READ AND SAVE THESE INSTRUCTIONS
• The device is designed to be installed INDOORS IN A SPACE THAT IS PROTECTED FROM RAIN AND FLOODING.
Install the unit with space to access the front panel for maintenance and
service.
• Avoid directing the discharge air at people, or over the water in pool areas.
• If used near a pool or spa; be certain there is NO chance the unit could fall into the water, splashed and that it is plugged into a GFI GROUND FAULT INTERRUPT OUTLET.
DO NOT place the device directly on structural members.
A drain pan MUST be placed under the unit if installed above a living area or above an area where water leakage could cause damage.

1. Intended Application for Dehumidifier
The dehumidifier is intended for use in residential applications to reduce the indoor humidity levels and increase comfort. With the optional ventilation ducting and ventilation control hookup, the device also provides precise amounts of ventilation air.
2. Approvals
The dehumidifier is certified by ETL to meet UL 474 and CSA 22.2 No. 92.

IMPORTANT: Prior to installation of the dehumidifier, the following checklist should be reviewed.
The dehumidifier can be installed in a variety of locations to meet the owner’s needs, and integrate with existing forced air systems or existing ductwork if desired. Choose a location with consideration to accessibility for service, drain availability, and power outlet location.
4.1A Power Accessibility
Unit should be located in an area where the cord’s length (10') should easily reach a 115 VAC electrical outlet with a minimum of a 15 A circuit capacity.
4.1B Accessibility
The installed dehumidifier should have at least 14 inches of clearance in the front of the device to service the filter.
Dehumidifier • For HVAC Installer Only
Place the dehumidifier on supports to raise the base of the unit. Do not place the dehumidifier directly on structural building members without vibration absorbers or unwanted noise may result.
The dehumidifier may be suspended from structural members by supporting the entire base of the unit via cross members, rigid frame, or the like. Do not hang the dehumidifier from the cabinet. Remember to place a drain pan under the unit if it is suspended above a finished area or above an area where water leakage could cause damage.
4.1D Sizing Chart
*This sizing chart is based on extreme climates where Rh levels are between 70 and 90% outdoor Rh. For less extreme climates then larger homes can be adequately served. Actual requirements may vary.

Refer to Section 6 for typical hookup diagrams. Some of the control wires leaving the dehumidifier may not be used with certain installations and should be left unconnected with wire nuts taped onto the stripped ends for safety.
4.3 Condensate (Water) Removal
The dehumidifier removes a large amount of moisture from the air and the device must be connected to a drain line that will carry away the excess water. A trap in the drain line is recommended and may be required by some local codes.
The drain line should be connected to the 3/4" male pipe thread adaptor on the front of the dehumidifier.
Care should be taken to install the drain line with a continuous slope of 1" per 10' to assure proper water removal.
4.4 Ducting
IMPORTANT: When connecting ventilation duct, remove the label and 6" round insulation plug from the ventilation duct opening. If not using ventilation feature, leave the insulation intact.

WARNING: Installation must be performed by a qualified service technician and must comply with local codes. Remove power to the device before installing or servicing the device. Failure to connect the device according to these instructions may result in damage to the device or the controls.
The dehumidifier plugs into a common grounded 115VAC outlet. The device draws 6.3 Amps under normal operating conditions. If used in an area which may become wet, a ground fault interrupter (GFI) protected circuit is recommended.
IMPORTANT: Do not install the humidistat where it may not accurately sense the relative humidity such as near HVAC supply registers, near exterior doors, on an outside wall, near a window, or near a water source.
For the ideal installation, draw air from the central part of the home and return it to the isolated areas of the home like the bedrooms, den, utility room, or family room. See Figure 2. Alternative installation option can be completed by drawing air directly from the return ducting and distributing through the supply air to the home.
Another installation option is ducting directly from the return and distributing directly back into the system's return. See Figure 3. Fresh air ventilation is optional and does not have to be ducted in order for the dehumidifier to properly function.
IMPORTANT: DO NOT draw air directly from the kitchen, laundry, or isolated basement.
Air may be drawn from a basement that is open to the home. All flexible ducting connected to the dehumidifier should be UL listed.
A short piece of flexible ducting on all dehumidifier duct connections is recommended to reduce noise and vibration transmitted to rigid ductwork in the structure. Ducting the dehumidifier as mentioned requires consideration of the following points:
