Dock Fans

Greenheck’s Dock Fan is a high velocity fan designed
to recirculate air in and around loading docks, trailers
and personnel working in the area. The model DF is
available with a light to provide additional visibility in
dark trailers or corners. The dock fan is constructed
of a 14 gauge steel housing, 12 gauge steel arm and
an aluminum propeller. The fan and optional light both
plug into a standard 115 volt outlet.

Performance up to 3,800 cfm at free air.

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.

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.

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 propeller 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 propeller faster than maximum
cataloged fan RPM. Adjustments to fan speed
signicantly 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 access doors to a duct while the fan is
running.

Receiving

Upon receiving the product, check to make sure
all items are accounted for by referencing the bill
of lading to ensure all items were received. Inspect
each crate for shipping damage before accepting
delivery. Notify the carrier if any damage is noticed.
The carrier will make notification on the delivery
receipt acknowledging any damage to the product. All
damage should be noted on all the copies of the bill of
lading which is countersigned by the delivering carrier.
A Carrier Inspection Report should be filled out by
the carrier upon arrival and reported to the Traffic
Department. If damaged upon arrival, file a claim
with carrier. 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.

Storage

Fans are protected against damage during shipment.
If the unit cannot be installed and operated
immediately, precautions need to be taken to prevent
deterioration of the unit during storage. The user
assumes responsibility of the fan and accessories
while in storage. The manufacturer will not be
responsible for damage during storage. These
suggestions are provided solely as a convenience to
the user.

INDOOR

The ideal environment for the storage of fans and
accessories is indoors, above grade, in a low humidity
atmosphere which is sealed to prevent the entry of
blowing dust, rain or snow. Temperatures should be
evenly maintained between 30° to 110°F (-1° to 43°C),
wide temperature swings may cause condensation
and “sweating” of metal parts. All accessories must
be stored indoors in a clean, dry atmosphere.

Remove any accumulations of dirt, water, ice, or
snow and wipe dry before moving to indoor storage.
To avoid “sweating” of metal parts allow cold

OUTDOOR

Fans designed for outdoor applications may be stored
outdoors, if absolutely necessary. Roads or aisles for
portable cranes and hauling equipment are needed.

The fan should be placed on a level surface to prevent
water from leaking into the fan. The fan should be
elevated on an adequate number of wooden blocks
so it is above water and snow levels and has enough
blocking to prevent it from settling into soft ground.
Locate parts far enough apart to permit air circulation,
sunlight and space for periodic inspection. To
minimize water accumulation, place all fan parts on
blocking supports so rain water will run off.

Do not cover parts with plastic film or tarps as these
cause condensation of moisture from the air passing
through heating and cooling cycles. Fan wheels
should be blocked to prevent spinning caused by
strong winds.

Inspection and Maintenance During Storage

While in storage, inspect fans once per month. Keep a
record of inspection and maintenance performed.

If moisture or dirt accumulations are found on parts,
the source should be located and eliminated. At each
inspection, rotate the propeller by hand ten to fifteen
revolutions to distribute lubricant on motor. If paint
deterioration begins, consideration should be given
to touch-up or repainting. Fans with special coatings
may require special techniques for touch-up or repair.

Machined parts coated with rust preventive should be
restored to good condition promptly if signs of rust
occur. Immediately remove the original rust preventive
coating with petroleum solvent and clean with lint­free cloths. Polish any remaining rust from surface
with crocus cloth or fine emery paper and oil. Do not
destroy the continuity of the surfaces. Thoroughly
wipe clean with Tectyl® 506 (Ashland Inc.) or the
equivalent. For hard to reach internal surfaces or for
occasional use, consider using Tectyl® 511M Rust
Preventive, WD-40® or the equivalent.

Removing from Storage

As fans are removed from storage to be installed
in their final location, they should be protected and
maintained in a similar fashion until the fan equipment
goes into operation.

parts to reach room temperature. To dry parts and
packages use a portable electric heater to remove any
moisture buildup. Leave coverings loose to permit air
circulation and to allow for periodic inspection.

The unit should be stored at least 3½ inches (89 mm)
off the floor on wooden blocks covered with moisture
proof paper or polyethylene sheathing. Aisles between
parts and along all walls should be provided to permit
air circulation and space for inspection.
