MOUNTING OF UNIT
1. Select a location that will minimize the noise from vibration and blower air noise to the building
occupants. Ideally in a service room intended for this purpose, where the temperature is
maintained between 40°F and 100°F and preferably, close to an exterior wall, to limit the length
of the insulated inlet air ducts.
2. Unit can be installed vertically or horizontally. When vertical, inlet must face down.
3. Make sure you can easily access the MAU to perform maintenance (24” minimum clearance
required from the electrical entrance cover).
4. The unit can be mounted within the ceiling (between joists if it will fit) or ceiling hung, at any
convenient location between the outside inlet hood and the fresh air discharge connection.
5. The discharge connection is where the conditioned fresh air is to be distributed within the
building, such as a HVAC return air duct or directly into a room or hallway register.
6. Leave a minimum space of 2” above the MAU.
DUCT SYSTEM
1. The outside hood, damper and ducting material are not included with this unit. It is the
installer’s responsibility to provide these materials and the necessary weather protection for the
inlet.
2. Select the inlet and outlet ducting size in accordance to the system design requirements.
3. Plan the simplest system, using the least number of elbows and joints. Keep the length of
insulated ducts to a minimum to prevent a choke point and improve ventilation.
4. Use only rigid metal ducts.
5. Do not install elbows less than twice the diameter of the MAU duct.
6. In cold climates, frost and or condensation may collect on metal parts of this product. Insulated
ducting must be used between the outside inlet air hood and the inlet of this unit. Insulate the
inlet ducts only, it is not necessary to insulate the outlet ducts as they are heated by the MAU.
The inlet damper and insulated inlet piping will prevent cold air migration and a slight incline will
keep moisture collection at the inlet end.
OUTDOOR INLET HOOD
Choose the appropriate location to install the fresh air inlet hood:
1. The fresh air intake hood must be installed at least 18 in. above the ground.
2. Make sure the fresh air intake hood is at least 6 ft. away from the following elements: garbage
can or any other contaminating source, gas meter outlet, dryer outlet, any other combustion
source outlet.
3. Install the fresh air intake hood at least 3 in. from the edge of the building to avoid turbulence,
which could cause dust to enter the hood.
4. See the illustration below on how to connect the fresh air intake hood to the exterior hood.
