General Safety Information
Only qualified personnel should install this unit.
Personnel should have a clear understanding of these
instructions and should be aware of general safety
precautions. Improper installation can result in electric
shock, possible injury due to coming in contact with
moving parts, as well as other potential hazards.
Other considerations may be required if high winds
or seismic activity are present. If more information
is needed, contact a licensed professional engineer
before moving forward.
2. The rotation of the wheel is critical. It must be
free to rotate without striking or rubbing any
stationary objects.
3. Motor must be securely and adequately
grounded.
4. Do not spin fan wheel faster than the maximum
cataloged fan rpm. Adjustments to fan speed
significantly affects motor load. If the fan RPM is
changed, the motor current should be checked
to make sure it is not exceeding the motor
nameplate amps.
5. Do not allow the power cable to kink or come
in contact with oil, grease, hot surfaces,
or chemicals. Replace cord immediately if
damaged.
1. Follow all local electrical and safety codes, as
well as the National Electrical Code (NEC), the
National Fire Protection Agency (NFPA), where
applicable. Follow the Canadian Electric Code
(CEC) in Canada.
6. Verify that the power source is compatible with
the equipment.
DANGER
7. Never open blower access doors while the fan is
running.
Always disconnect power before working on or
near a unit. Lock and tag the disconnect switch or
breaker to prevent accidental power up.
CAUTION
When servicing the unit, motor may be hot enough
to cause pain or injury. Allow motor to cool before
servicing.

Mounting Instructions
Hanging Instructions
Greenheck’s Modular Small Cabinet Fan (MSCF)
should be lifted by the factory supplied lifting lugs
(see Figure 1) or frame rails and a spreader bar
(see Figure 2) to prevent damage from occurring to
the equipment. Avoid twisting or uneven lifting of
equipment. Do not lift equipment by coil connections
or headers. The unit must remain upright during lifting.
All access doors and panels must be closed during
lifting to avoid damage.
The MSCF should be hung by the factory supplied
lifting lugs or field supplied frame rails as shown
respectively in Figures 3 and 4. The number of
hanging brackets used will be determined by the
number of fan modules.
