above the kitchen exhaust fan motor. We suggest installation of Switch Assembly collar be no
higher than 24” above exhaust fan motor. If you are unable to install in a straight duct run, a
90 degree elbow may be required.
Low voltage wiring (A) from motorized fresh air damper is
connected directly to the 24V power transformer.
Low voltage wiring (B) from motorized fresh air damper is
connected to Switch Assembly.
Wire © is connected from Switch Assembly to 24V Power
Transformer.

Technical Specifications Continued
Passive Air Flow Installation
The replenishment or
make-up air must be drawn
from the outside of the
home.
Outside fresh air inlet must
be installed on the exterior
of the house a minimum
distance of 10 ft. from com-
bustion vents and other
exhaust openings. Locate
the fresh air inlet away from
any outside motor, genera-
tor, pump, BBQ grill,
hearth/fire pit, chemical
storage area, or any poten-
tially hazardous exposure
areas.
Air Handling Fan Direct Connect Installation
Using a revolutionary new method of installation, the MA7, MA8 & MA10 have the ability to connect
directly to the HVAC air circulation fan motor. This provides cleaner and healthier air by utilizing
the HVAC filtration system during operation of our residential make-up air system.
During operation of the kitchen range hood, the Switch Assembly will activate the air circulation fan
motor independently of the heating and cooling system to open a motorized damper allowing fresh
air to enter through the return air duct. The outside air will then pass through the furnace filter prior
to being distributed throughout the air supply system. When air is no longer being exhausted by the
kitchen range hood, the Switch Assembly will return to the “off” position. The installation method
will override or affect the normal function of the HVAC thermostat or corresponding components.
The HVAC system will heat and cool during operation of the make-up air system as needed by
measuring the internal air temperature of the home.
The 90 degree Elbow model can be attached directly to an outside wall, giving the installer or
HVAC contractor the ability to complete even the tightest installations. Elbow must be attached to
rigid ducting.
