Installation, Operation and Maintenance Manual
Please read and save these instructions. Read carefully before attempting to assemble, install, operate or maintain the
product described. Protect yourself and others by observing all safety information. Failure to comply with instructions
could result in personal injury and/or property damage! Retain instructions for future reference.

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.
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 Electrical Code (CEC) in
Canada.
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.
6. Verify that the power source is compatible with the
equipment.
7. Never open blower access doors while the fan is
running.

IG/IGX Make-Up Air Unit
DANGER
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.
FOR YOUR SAFETY
If you smell gas:
1. Open windows.
2. Do not touch electrical switches.
3. Extinguish any open flame.
4. Immediately call your gas supplier.
FOR YOUR SAFETY
The use and storage of gasoline or other
flammable vapors and liquids in open
containers in the vicinity of this appliance is
hazardous.
WARNING
Improper installation, adjustment,
alteration, service or maintenance can
cause property damage, injury or death.
Read the installation, operating and
maintenance instructions thoroughly before
installing or servicing this equipment.
