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

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

Horizontal

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 blower access doors while the fan is
running.

WARNING!

Impro per installation, adj ustment,
alteration, service or maintenance
can cause property damage, injury or
death. Read the installation, operating

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 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.

OUTDOOR

Units 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 unit. The unit should be
elevated on an adequate number of wooden blocks so
that 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 unit parts on
blocking supports so that 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.

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
clean thoroughly 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

Lifting Area
(4 places)

Supply
Ductwork
by Others

Sealant

Ductwork

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.

Installation

NOTE

The use of all lifting brackets and a set of spreader
bars is mandatory when lifting unit.

STAND ALONE

1. Install Curb: Position curb on the roof. Refer to
the CAPS submittal for curb location in relation to
the unit. Verify that all unit supports are level, shim
if necessary. Attach curb to roof and flash into
place.

4.

Install Supply Unit: Use a crane and a set of
spreader bars hooked to the factory lifting lugs (as
shown in the diagram) to lift and center the unit on
the curb. Use self-tapping sheet metal screws to
fasten unit to the curb.

5. Assemble Weatherhood: See the reference
section for weatherhood assembly instructions.

Complete Installation

Illustrations show the complete installation of a
standard DB and HZ and extended DB unit.

2. Install Ductwork: Good duct practices should
be followed for all ductwork. All ductwork should
be done in accordance with SMACNA and AMCA
guidelines, NFPA 96 and any local codes.

See the CAPS submittal for the recommended

supply duct sizes. The ductwork should extend far
enough above the roofline to meet the supply unit
once it is installed.

3. Apply Sealant: Before installing supply unit, apply
a sealant around the perimeter of the supply duct
to isolate the fan and minimize vibration.
