Ultra-Aire SD12 Installer’s & Owner’s Manual

FOR HVAC INSTALLER ONLY

3.1B Condensing Unit Location

The condensing unit should be located outside of the conditioned 
space, but as close as possible to the dehumidifier to minimize the 
length of the connecting lines. The maximum line set length is 50 feet. 
In all cases keep the following cautions in mind:
• Install the condensing unit with space to access the top and side pan-
els for maintenance and service. DO NOT INSTALL CONDENSING UNIT 
WITH THE TOP PANEL OR SIDE PANELS INACCESSIBLE (See FIGURE 2 for 
diagram).
• Avoid discharging air directly at people, or over the water near pool 
areas.
• If used near a pool or spa, be certain there is NO chance the  
condensing unit could fall into the water or be splashed and that it is  
supplied by a GROUND FAULT INTERRUPTER. 
• Place the condensing unit where it is protected from extreme outdoor 
weather (rain, wind, etc…)
• Place the condensing unit on a level pad (or bracket) where the unit 
can be securely attached by the base.
• Place the condensing unit at least 1” above ground level
• Place the condensing unit where there is adequate space for the unit 
and the air required by the unit
• DO NOT place the condensing unit where the sound and vibration 
caused by the running unit will cause a nuisance.
• DO NOT use the condensing unit as a bench or table. 
• DO NOT place the condensing unit in direct sunlight.
• The minimum installation clearances for the condensing unit are  
shown below.

 

 ROOF DAMAGE!

 

THIS SYSTEM CONTAINS 

BOTH REFRIGERANT AND OIL. SOME RUBBER ROOFING MATERIAL 
MAY ABSORB OIL AND CAUSE THE RUBBER TO SWELL WHEN IT 
COMES INTO CONTACT WITH OIL. THE RUBBER WILL THEN BUBBLE 
AND COULD CAUSE LEAKS. PROTECT THE ROOF SURFACE TO 
AVOID EXPOSURE TO REFRIGERANT AND OIL DURING SERVICE AND 
INSTALLATION. FAILURE TO FOLLOW THIS NOTICE COULD RESULT  
IN DAMAGE TO ROOF SURFACE.

Mount the base of the condensing unit to a sturdy level pad (or bracket) 
using 3/8” (10mm) bolts. The condensing unit may be mounted to a 
wall (with brackets) or placed on a roof. Ensure the mounting of the 
condensing unit can withstand strong winds and earthquakes when 
mounting above ground level. Vibration dampening material may be 
installed between the condensing unit base and the mounting pad if 
required. The base dimensions of the condensing unit are shown in 
FIGURE 2.

3.2 Electrical Requirements 

 WARNING!

 

ELECTRIC SHOCK HAZARD. CAN CAUSE 

INJURY OR DEATH. UNIT MUST BE GROUNDED IN ACCORDANCE 
WITH NATIONAL AND LOCAL CODES. DISCONNECT ALL REMOTE 
ELECTRIC POWER SUPPLIES BEFORE OPENING ACCESS PANEL.  
UNIT MAY HAVE MULTIPLE POWER SUPPLIES.

Field wiring must comply with the National Electric Code (C.E.C. in 
Canada) and any applicable local codes or ordinances.

 WARNING!

 

DO NOT ALLOW THE YELLOW LEAD TO 

CONTACT THE RED LEAD OR WHITE LEAD FROM THE ULTRA-AIRE 
DEHUMIDIFIER OR THE TRANSFORMER WILL BE DAMAGED.

3.2A Dehumidifier Electrical Power Connections

The Ultra-Aire SD12 Dehumidifier unit plugs into a common 120Vac 
grounded outlet. The Dehumidifier draws less than 2A and can be 
plugged into a shared branch circuit. If installed in a wet area (or 
basement prone to flooding), a ground fault interrupter protected 
circuit is required (See FIGURE 3 for schematic).
