The Ultra-Aire 65H generates condensate. Install a 3/4" male
nominal pipe thread adapter to the drain pan. It is necessary
to assemble your own drain pipe assembly utilizing 3/4"
PVC pipe to get the condensate to a floor or other drain. Pipe
is commonly available in 10’ lengths from building supply,
plumbing or hardware stores. Grade of pitch should be 1"
per 10'.
4.3A Lifting Condensate
A condensate pump may installed if lift is required to dispose
of the condensate.
4.3B Condensate Pump Kit (4028085)
A condensate pump kit is available from the factory for use
with the Ultra-Aire 65H and provides 15' of lift. 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 the blue (#5) lead from the Ultra-Aire 65H to the
the control panel. If the pump fails, this switch opens the
compressor control circuit and stops water production before
the reservoir overflows. The Ultra-Aire 65H will continue to
ventilate or circulate air as normal, but will not dehumidify
until this switch closes.
4.4 Ducting
CAUTION
Replacing the filter requires the return duct to be
removed. Failure to use flex duct will prevent filter
access. Three feet of flex duct should be adequate to
access the filter.
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. The ductwork
of the existing heating system can be used to supply air to
the home. If the existing supply goes to isolated areas of
the home, discharge the supply of the Ultra-Aire 65H into
the supply of the existing heating system. Installation of a
separate supply duct to the Ultra-Aire 65H from a central
area is recommended.
4.4A Supply Air
CAUTION
DO NOT draw air directly from the kitchen, laundry, or
isolated basement.
You may draw air from a basement that is open to the home.
All flexible ducting connected to the Ultra-Aire 65H should be
UL listed.
A short piece of flexible ducting on all Ultra-Aire 65H duct
connections is recommended to reduce noise and vibration
transmitted to rigid ductwork in the structure. Ducting the
Ultra-Aire 65H as mentioned requires consideration of the
following points:
Duct Sizing: For total duct lengths up to 25', use a minimum
8" diameter round or equivalent rectangular. For longer
lengths, use a minimum 10" diameter or equivalent. Grills
or diffusers on the duct ends must not excessively restrict
airflow.
Connecting to existing HVAC systems:
An optional 8"
check backdraft damper is available from the factory to
prevent reverse air flow through the Ultra-Aire 65H. If the
Ultra-Aire 65H is ducted to the supply of an air handler, the
check damper should be placed in the Ultra-Aire 65H supply
duct.
CAUTION
Contact the factory when connecting to a static pressure
of greater than or equal to +.5" WG.
