Roof Damage Warning And Disclaimer
GSI DOES NOT WARRANT ANY ROOF DAMAGE CAUSED
BY EXCESSIVE VACUUM OR INTERNAL PRESSURE FROM
FANS OR OTHER AIR MOVING SYSTEMS. ADEQUATE
VENTILATION AND/OR "MAKEUP AIR" DEVICES SHOULD
BE PROVIDED FOR ALL POWERED AIR HANDLING SYS-
TEMS. GSI DOES NOT RECOMMEND THE USE OF DOWN-
WARD FLOW SYSTEMS (SUCTION). SEVERE ROOF DAM-
AGE CAN RESULT FROM ANY BLOCKAGE OF AIR PAS-
SAGES. RUNNING FANS DURING HIGH HUMIDITY/COLD
WEATHER CONDITIONS CAN CAUSE AIR EXHAUST OR
INTAKE PORTS TO FREEZE.

INSTALLATION
Pre-Installation Requirements
Foundation Use the dimension illustration in the speci-
fications section of this manual to determine the physi-
cal size of the fan to be installed. Use the dimensions
shown to determine the position of the fan installation
with respect to other equipment.
For proper operation of your fan, the unit is to be
mounted on a level pad. The fan should not be anchored
to the pad, but it should be allowed to “float” on the pad.
The fan pad should be offset 2.00” below the top of the
bin foundation. Refer to the dimension illustration “Fan
Pad Location” in the specifications section of this manual
for recommendations of pad placement with respect to
various catalog transition ducts.
Transition The transition duct should be all metal con-
struction, with a gradual angle to the rectangular open-
ing in the bin wall. The duct should allow for a smooth
transition with minimal resistance of the airflow from the
fan discharge to the bin plenum. Keep the entrance of
the plenum as clear as possible from obstructions by
floor support.
Roof Exhaust Adequate exhaust air openings in the
roof are required to prevent any additional back pres-
sure from building in the bin. See “Roof Damage Warn-
ing” on the previous page.
Power Supply Adequate power must be supplied to
the fan for reliable operation. Consult the local power
company and have a representative survey the installa-
tion. Only the power company can ensure that their sys-
tem is sized properly to provide adequate service to the
installation and new equipment.
Wire Size Undersized wire can lead to voltage drop
which causes motor overheating and shortened motor
life. Use the electrical specifications chart in this manual
to size the supply wire according to the horsepower of
the fan and the distance to the power supply. Refer to
the “Fan Specifications” section of this manual to find
the full load current of the motor for a given fan size.
The full load current can also be found on the motor
nameplate.
Service Disconnect Each fan motor must be supplied
with an independent power circuit, equipped with a fused
disconnect switch. Locate this switch near the unit, as
the power should be shut off before servicing the fan.
It is the customer’s responsibility to provide a
fused disconnect and motor overload protection. These
must be properly sized and connected to allow proper
motor operation. Failure to provide these components
could cause severe motor damage and void the
manufacturer’s warranty.
Fan Installation
1. Remove packaging materials and inspect fan for
any shipping damages. Report these at once to
the shipper.
2. Check all fasteners on the fan to make sure they
are tight ( fasteners may loosen during shipment ).
Tighten any loose fasteners, check for proper
clearance and retighten.
3. Check all electrical connections that may have
loosened during shipment.
4. Rotate the fan wheel. Wheel should rotate freely
and should not make contact with the housing
sides or inlet cone.
5. Place fan in proper location on the fan pad. Attach
fan to transition duct and seal connection with
caulk.
6. Check all joints and seams around the lower part of
the bin. Verify that these are well sealed to prevent
air leakage from the bin plenum. Inspect the
transition duct as well. Seal any leaks that may be
present to prevent air losses that reduce fan
efficiency.
7. Level fan. Fan pad should be poured flat and level,
however, it may be necessary to adjust the legs
provided on the fan housing to level the fan. The
legs should be adjusted so that when level all five

Electrical Installation
1. Verify that the incoming power supply has been
deemed adequate by the local power company.
2. Verify that the wiring supplying power to the fan is
sized correctly for the distance away from supply
and fan horsepower. (See tables in specification
section of this manual)
3. Verify that the safety disconnect is installed and
sized correctly for the fan size. (See tables in
specification section of this manual)
4. Install a machine to earth ground for each individual
fan. Refer to the “Ground Rod Installation” page in
this manual.
5. The following wires must be supplied to each fan.
Units without control transformers require a
separate neutral and earth ground connection.
1PH 230V L1, L2, N, G
3PH 230V L1, L2, L3, N, G
3PH 230V with optional
transformer kit L1, L2, L3, G
3PH 460V/575V L1, L2, L3, G
INSTALLATION
DANGER
ALWAYS DISCONNECT AND LOCK
OUT POWER BEFORE WORKING
ON OR AROUND FAN.
IMPORTANT
ELECTRICAL INST ALLA TION MUST BE PERFORMED BY A
QUALIFIED ELECTRICIAN, IN ACCORDANCE WITH
NA TIONAL AND LOCAL ELECTRICAL CODES. ANY
VIOLA TION OF ELECTRICAL WIRING CODES COULD
JEOP ARDIZE THE W ARRANTY .
6. The starter controls require 115VAC power to
operate. On 230 Volt 3 Phase units, this power is
supplied by L1 to neutral.
Check this voltage before starting unit. If voltage is not
within 105-125VAC, check for proper voltage on L2 or
L3 and move to appropriate leg. If voltage is not
acceptable, install a 0.25 KVA step-down transformer.
(Note: Grounded B and some open delta power supplies
will require this transformer kit.)
Final Check
Check to make sure all safety guards are in place and
not damaged. Replace damaged parts.
Check to make sure all decals are visible and not
damaged. Replace damaged decals.
Check to make sure all control boxes are closed and no
wiring is exposed.
Test Run
When the fan is completely installed, the unit will need to
be checked for proper rotation. Provide power to the fan
controls and start the fan momentarily. Make sure that
the fan wheel rotation is in the direction that the decal on
the fan housing illustrates. If the decal is missing, note
that the wheel should operate counterclockwise when
viewed through the inlet guard on standard construction
fans. If the wheel is rotating the wrong direction, have
your electrician correct the wiring.
CAUTION
THE VOL T AGE BETWEEN L1 AND N MUST BE
1 15VAC. ANY OTHER VOLTAGE WILL CAUSE
DAMAGE TO EQUIPMENT.
legs touch the pad. Fans not resting on support
legs may have excess vibration which can lead to
premature wear and tear on fan components.
