Mixed Flow Inline Fan

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 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.

Precaution should be taken in explosive
atmospheres.

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

Fans 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
the ability of the fan to resist corrosion.

Fans should never be lifted by the shaft, fan housing,
motor, belt guard, windband or accessories.

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. The following
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°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 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.

OUTDOOR

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.

The use of a tarp to cover the unit will aid in keeping it
clean and dry. Avoid using a black plastic tarp as it will
promote condensation.

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 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 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.

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.

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

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

2. Rotate the fan wheel by hand and assure no parts
are rubbing. Access to the wheel is obtained
through an access panel located on the side of the
fan housing.

3. Ensure proper wheel settings for radial gap and
alignment. See below.

Radial Gap, Overlap & Alignment

Efficient fan performance can be maintained by having
the correct radial gap, overlap and alignment. These
items should be checked before start-up and after the
fan has been in operation for 24 hours.

TCF Radial Gap

Radial gap is adjusted by loosening the inlet
cone bolts and centering the cone on the wheel.
If additional adjustment is required to maintain a
constant radial gap, loosening the bearing bolts and
centering wheel is acceptable
as a secondary option.

TCF Overlap

Overlap is adjusted by
loosening the wheel hub from
the shaft and moving the
wheel to the desired position
along the shaft. The chart
shows the proper distance
between the wheel and
the inlet cone.

A

QEI/QEID Radial Gap

Adjust inlet cone position such that the radial gap
between the wheel cone and inlet cone is evenly
distributed around the wheel.

QEI/QEID Alignment

If necessary, adjust wheel position by loosening the
wheel hub from the fan shaft so that a straight edge
held tight to the wheel cone just touches the inlet
cone. Refer to drawing below.

Installation

Installations with poor inlet or discharge
configurations may result in reduced fan performance.

Ducted Installations

Inlet Duct Turns – Installation of a duct turn or elbow
too close to the fan inlet reduces fan performance.
Restricted or unstable flow at the fan inlet can cause
pre-rotation of incoming air or uneven loading of the
fan wheel, yielding large system losses and increased
sound levels. To achieve full fan performance, there
should be at least one fan wheel diameter between
the turn or elbow and the fan inlet.

Discharge Duct Turns – Fan performance is reduced

when duct turns are made immediately off the fan
discharge. To achieve cataloged fan performance
there should be at least three equivalent duct
diameters of straight ductwork between the fan
discharge and any duct turns.
