Belt Guards

Greenheck offers 
various types of 
customized belt guards 
dependent upon fan 
model, arrangement 
and motor position. 
Motor position is 
determined from the 
drive side.

The various types of belt guards are shown in 
illustrations. If the guard is not purchased from 
Greenheck, they must be supplied by the installer  
or owner.

If the belt guard is not factory mounted or was not 
supplied by manufacturer, then it must be field mounted. 
Brackets and mounting hardware are the responsibility 
of the installer. The figures below illustrate suggested 
attachment points for belt guard mounting bracket 
locations. These locations vary with motor mounting 
position, arrangement, and fan type. The bearing 
supports and fan structure are used in most instances 
and when the motor is not mounted to the fan itself, a 
bracket should also be located near it. This information 
is intended only as a guide and actual field conditions 
may dictate another mounting location for the guard 
brackets. Refer to local codes for securing guarding.

Electrical Connections

Before electrical connections are made, the supply 
voltage, phase and ampere capacity must be checked 
for compatibility with the fan motor. In addition, the 
supply wiring must be properly fused and conform to 
local and national electrical codes. If the unit is supplied 
with a safety disconnect switch, ensure proper wiring 
to the fan motor. Be sure the disconnect is switched to 
the “OFF” position before connecting supply wires. If 
no disconnect is supplied, ensure the supply wire is not 
live before connection. Supply wires are then connected 
to the optional safety disconnect switch (if supplied) or 
motor.
