3. Installation
3.1 Location
3.1A Dehumidifier Location
The Ultra-Aire SD12 Dehumidifier can be installed in a variety of
locations to meet the owner’s needs as listed below. In all cases
keep the following cautions in mind:
• It is designed to be installed INDOORS IN A SPACE THAT IS
PROTECTED FROM RAIN AND FLOODING.
• Install the dehumidifier with space to access the back and side
panels for maintenance and service and also to allow easy access
to the filter cover panel. DO NOT INSTALL DEHUMIDIFIER WITH THE
SIDE PANEL OR FILTER COVER PANEL INACCESSIBLE (See FIGURE 1
for diagram).
• Avoid discharging the supply air directly at people, or over the
water in pool areas.
• If used near a pool or spa, be certain there is NO chance the
dehumidifier could fall into the water or be splashed and that it is
plugged into a GROUND FAULT INTERRUPTER.
• DO NOT use the Ultra-Aire SD12 as a bench or table.
• DO NOT place the Ultra-Aire SD12 directly on structural members.
Provide vibration isolation in order to minimize operational vibration
and/or noise.
• A drain pan MUST be placed under the dehumidifier if installed above
a finished living area or above an area where water leakage could cause
damage.
Place the Ultra-Aire SD12 on supports that raise the base of the unit 2.5”
above the drain pan beneath it. Raising the Ultra-Aire SD12 will help the
dehumidifier drain with gravity flow. Do not place the Ultra-Aire SD12
directly on structural building members without vibration absorbers or
unwanted noise may result.
The Ultra-Aire SD12 may be suspended with steel hanger straps or a
suitable alternative from structural members. The dehumidifier must be
supported from underneath; don’t hang from sides or ends. Remember
to place a drain pan under the dehumidifier if it is suspended above a
finished area or above an area where water leakage could cause damage.
The Ultra-Aire SD12 should be located near the existing HVAC system
to minimize the required ductwork for connecting the Ultra-Aire SD12 to
the existing air handling system. The Ultra-Aire SD12 requires a drain to
dispose of the condensate created. Often the Ultra-Aire SD12 can be
connected to the existing air handler drain. The controls for the Ultra-Aire
SD12 are remote from the unit and must be located in the space that is
to be conditioned. The controls are low voltage (24 volt) and should be
connected to the Ultra-Aire SD12 with low voltage thermostat cable.
If fresh air ventilation is desired, thought should be given to the
location for the fresh air ducting. A 6” diameter round insulated duct
can be installed on the Ultra-Aire SD12 and run to the outside of the
structure to bring in fresh air. Use an 8” insulated round duct for lengths
greater than 50 feet or if more than 100 CFM of fresh air is needed.
Consult local codes for necessary distances from exhaust ports when
installing fresh air return.
