Ultra-Aire SD12 Installation Instructions
DRAIN INSTALLATION
The Ultra-Aire SD12 dehumidifier generates condensate.
Place a secondary drain pan with a float switch under the dehumidifier if it is suspended above a finished
area or above an area where water leakage could cause damage.
A drain trap is required for the dehumidifier to drain properly. Install a 3/4" threaded male NPT adapter to the
drain pan. Install a drain pipe assembly utilizing 3/4" PVC pipe to transport the condensate to a drain. Pitch
of drain should be 1" per 10'.
An optional condensate pump kit is available for use with the Ultra-Aire SD12 and may be installed if lift is
required to dispose of condensate. Condensate is automatically pumped to a remote location when the
water level in the pump’s reservoir rises to close the float switch.
The pump also contains a safety float switch. The white leads from this switch extend from beneath the
pump cover. This switch should be installed in series with the field wire that connects to the common lead
from the Ultra-Aire SD12 to the control panel. If the pump fails, this switch opens the common control circuit
and stops water production before the reservoir overflows. Contact a qualified electrician to install the safety
float switch to the Ultra-Aire SD12 dehumidifier.
Note: An optional condensate pump kit and an automatic cut-off device can be purchased through your
dealer or online.
