Series L: Models LB, LBP, LD, and LDP
Low Silhouette Centrifugal Roof Exhaust Fans
Only qualified personnel should install this fan.
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) and
the National Fire Protection Agency (NFPA),
where applicable. Follow the Canadian Electric
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 max cataloged
fan RPM. Adjustments to fan speed significantly
effects 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 access doors to a duct while the fan
is running.
DANGER
Always disconnect, lock and tag power source before
installing or servicing. Failure to disconnect power source
can result in fire, shock or serious injury.
CAUTION
When servicing the fan, motor may be hot enough to
cause pain or injury. Allow motor to cool before servicing.
CAUTION
Precaution should be taken in explosive atmospheres.
