crawlspace. Duct the other side of the tee to the air return of the
existing HVAC system. If the existing HVAC system has a central
return, duct the other side of the tee to the air supply of the existing
HVAC system. Connect a duct from outside to the 6" collar of the
Ultra-Aire if you wish to provide fresh make-up air.
3.4E Installation in an Attic with an Existing Forced
Air HVAC System
ALWAYS install a catch pan for condensate under the
Ultra-Aire in an attic or condensate may drip down on
the ceiling of the living space below.
Locate a separate return for the Ultra-Aire in a central area of the
structure. Duct the supply of the Ultra-Aire to the air supply of the
existing HVAC system. If the existing HVAC system has a central
return, duct the supply of the Ultra-Aire to the air supply of the
existing HVAC system. Connect a duct from outside to the 6" collar
of the Ultra-Aire if you wish to provide fresh make-up air.
3.4F Installation in a Structure with Two Forced Air
HVAC Systems
Attach the Ultra-Aire return to to a independent return from the
upper level. Attach the Ultra-Aire supply to the supply of the
basement HVAC system. This will promote circulation of air through
the whole structure from the upper level to the lower level through
the Ultra-Aire . If the Ultra-Aire is not connected to both HVAC
systems, it will not control the humidity and ventilation of the entire
structure. Connect a duct from outside to the 6" collar of the Ultra-
Aire if you wish to provide fresh make-up air.
3.4G Installation in a Structure with No Existing
Forced Air HVAC Systems
When installing the Ultra-Aire in a structure that does not have a
forced air HVAC system, a single return for the Ultra-Aire should
be installed in central open area of the structure.
DO NOT locate
the return in a bathroom or a kitchen. The supply of the Ultra-
Aire should be located in the remote areas of the structure (such
as bedrooms, den, etc.). By ducting this way the air inside the
structure will circulate through the Ultra-Aire to be filtered and
dehumidified. Connect a duct from outside to the 6" collar of the
Ultra-Aire if you wish to provide fresh make-up air.
3.5 Quiet Installation
Loosen the compressor mounting bolts from the base of the unit.
Do not remove the bolts, but loosen them so the compressor
mounting grommets are not compressed. These bolts are tightened
at the factory to prevent damage during shipping. Loosening them
will reduce the amount of compressor vibration. Make sure none
of the compressor tubes are pressed against the cabinet or front
panel.
A length of 10 feet or more of acoustical flex ducting on the outlet
of the Ultra-Aire will reduce air noise from the blower. A length of
flexible ducting on all Ultra-Aire duct connections is recommended
to reduce noise and vibration transmitted to rigid ductwork in the
structure.
4. Controls
The Ultra-Aire can be equipped with various accessories to
enhance its operation. A remote control panel must be used with
the Ultra-Aire . There are two remote control panels from which to
choose. The humidity/fan control panel is used to control humidity
and the fan. The ventilation timer and humidity control panel is
used to control ventilation, humidity and the fan.
4.1 Humidity/Fan Control Panel
See Figure 1: The humidity/fan control panel automatically controls
the humidity of the living space. The humidity/fan control panel
contains an adjustable humidity control and a fan switch. This
panel should be mounted in a central area of the structure where
it can accurately sense the humidity of the air in the living space.
The panel has small perforations that must remain open to the air
within the living space for accurate humidity sensing.
The humidity/fan control panel can be used in conjunction with
the optional fresh air damper. When used with the optional fresh
air damper, the fan/filter switch will act as a fresh air ventilation
control. When the switch is ON (in this configuration), the fan will
run, the fresh air damper will open, and fresh air will be filtered
and brought into the structure. When the switch is OFF, the fresh air
damper will close and the fan will operate only when the humidity
control calls for dehumidification.
4.2 Ventilation Timer and Humidity Control Panel
See Figure 2: The ventilation timer and humidity control panel
automatically controls both the ventilation and the humidity of
the living space. The ventilation timer and humidity control panel
contains an adjustable humidity control, a fan switch, and a
ventilation timer. This panel will control the humidity and allow
programmed ventilation of the living space. This panel works
in conjunction with the optional fresh air damper to provide
ventilation.
This panel should be mounted in a central area of the structure
where it can accurately sense the humidity of the air in the living
space. The panel has small slots that must remain open to the air
within the living space for accurate humidity sensing.
