Housed Plenum Array, Plug and Plenum
General Safety Information
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), 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.
Receiving
Upon receiving the product check to ensure all items
are accounted for by referencing the delivery receipt or
packing list. Inspect each crate or carton for shipping
damage before accepting delivery. Alert the carrier
of any damage detected. The customer will make
a notation of damage (or shortage of items) on the
delivery receipt and all copies of the bill of lading which
is countersigned by the delivering carrier. If damaged,
immediately contact your Greenheck representative.
Any physical damage to the unit after acceptance is not
the responsibility of Greenheck Fan Corporation.
Unpacking
Verify that all required parts and the correct quantity
of each item have been received. If any items are
missing report shortages to your local representative to
arrange for obtaining missing parts. Sometimes it is not
possible that all items for the unit be shipped together
due to availability of transportation and truck space.
Confirmation of shipment(s) must be limited to only
items on the bill of lading.
