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 Electric Code
(CEC) in Canada.

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

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.

When servicing the unit, motor may be hot enough
to cause pain or injury. Allow motor to cool before
servicing.

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 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.

Handling

Units are to be rigged and moved by the lifting
brackets provided or by the skid when a forklift is
used. Location of brackets varies by model and size.
Handle in such a manner as to keep from scratching
or chipping the coating. Damaged finish may reduce
ability of unit to resist corrosion.

Storage

Units 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 unit 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

units 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°F (-1°C) and
110°F (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 parts to
reach room temperature. To dry parts and packages
use a portable electric heater to get rid of any
moisture build up. Leave coverings loose to permit air
circulation and to allow for periodic inspection.

The unit should be stored at least 3½ in. (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.

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 fan wheel by hand ten to fifteen
revolutions to distribute lubricant on motor. Every
three months, the fan motor should be energized. 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 lint-free cloths. Polish any remaining rust from
surface with crocus cloth or fine emery paper and oil.
Do not destroy the continuity of the surfaces. Wipe
thoroughly 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 or WD-40® or the equivalent.

REMOVING FROM STORAGE — As units are removed

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

Prior to installing the unit and system components,
inspect the unit assembly to make sure it is in working
order.

1. Check all fasteners, set screws on the fan,
wheel, bearings, drive, motor base, and
accessories for tightness.

2. Rotate the fan wheel(s) by hand and assure no
parts are rubbing.

Mounting 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.

Spreader Bar

Hanging Instructions

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.
