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.
