Greenheck Fan SE1, SS1 manual Wall Housing Mounting Arrangements

Wall Housing Mounting Arrangements

The wall housing is designed to reduce installation time and provide maximum installation flexibility. Attached accessories such as backdraft dampers, guards and weatherhoods may mount to either end. As a result a wide variety of configurations are available to accommodate the needs of the system designer.

The following information will help determine the correct arrangement required. When ordering specify arrangement by the drawing number 1A, 2A, 1B or 2B as shown in the diagrams below.

NOTE: Weatherhoods are strongly recommended for all configurations to help prevent moisture infiltration. Mounting flange, damper and guard ship factory mounted on all arrangements as shown except when ordered as a kit.

Mounting Arrangements for Interior Service Applications

The arrangements shown below are the most commonly used and should be considered first for most applications. The choice of flush interior or exterior mounting are based on appearance or space considerations.

Belts, pulleys and motors are serviced from inside the building with these arrangements. For applications requiring service from outside the building, see reverse mounting arrangements below.

Mounting Arrangements for Exterior Service Applications (Optional)

Reverse mounting a wall housing simply involves installing the wall housing through the wall opening in the opposite direction of the above configurations. This results in an opposite effect on fan function. An exhaust fan in a wall housing will function as a supply fan when the housing is reverse mounted.

Example: When the exhaust arrangement shown as 1A is reversed (shown as 1A-R) the same unit now becomes a supply arrangement. The construction, fan position and mounting angle location in both configurations remain identical.
