Centrifugal Inline Fans

Installation, Operation and Maintenance Manual

Please read and save these instructions for future reference. 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!

Model SQ
Direct Drive

Model SQ is a direct drive
centrifugal inline exhaust
fan. These fans are
specically designed for inline
applications. Performance
capabilities range up to 5,000
cfm (8,500 m3/hr) and up to

2.0 in. wg (498 Pa) of static
pressure. SQ fans are available
in thirteen sizes with nominal wheel diameter ranging
from 6 to 16 inches (152 to 406 mm) (060 - 160 unit
sizes). Each fan shall bear a permanently afxed
manufacture’s engraved metal nameplate containing
the model number and individual serial number.

General Safety Information

Only qualied 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
seismic activity is 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 re, 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.

Model BSQ
Belt Drive

Model BSQ is a belt drive
centrifugal inline exhaust fan.
These fans are specically
designed for inline applications.
Performance capabilities range
up to 27,200 cfm (46,200 m3/hr)
and up to 4.0 in. wg (996 Pa) of
static pressure. BSQ fans are

available in fourteen sizes with
nominal wheel diameter ranging from 7 to 42 inches
(178 to 1067 mm) (070 - 420 unit sizes). Each fan shall
bear a permanently afxed manufacture’s engraved
metal nameplate containing the model number and
individual serial number.

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 signicantly
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 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 notication 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 lled out
by the carrier upon arrival and reported to the Trafc
Department. If damaged upon arrival, le 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. Conrmation of shipment(s) must be limited to
only items on the bill of lading.

Handling

Move fan to desired location and determine position of
access panels, discharge and motor. Make sure inlet
and outlet have at least 2 times the wheel diameter
(duct diameter) before any obstructions like an elbow
or transition. Attach the fan to a suitable framework
as specified, (hanging or base vibration isolators are
recommended). See chart 1 on page 3 for physical
dimensions (Figures 1 and 2) and chart 3 on page 4
for dimensions of vibration isolator centerlines
(Figures 5-7).
The motor’s amperage and voltage ratings must be
checked for compatibility to supply voltage prior to
final electrical connection. Electrical lead in wires
are then connected to the factory supplied safety
disconnect switch. All wiring must conform to local
and national codes.

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.

2

Model SQ/BSQ • Centrifugal Inline Exhaust Fans

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
buildup. Leave coverings loose to permit air circulation
and to allow for periodic inspection.
The unit should be stored at least 3 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

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
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 fan parts on blocking
supports so that rain water will run off.
Do not cover parts with plastic lm 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 wheel by hand ten to fteen
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 ne 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 nal location, they should be protected and
maintained in a similar fashion until the fan equipment
goes into operation.
