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 re-tighten.
3. Check all electrical connections that may have loosened during shipment.
4. Rotate the fan blade. Blade should rotate freely and should not make contact with the housing
sides or venturi.
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 shim the legs
provided on the fan housing to level the fan. Fans not resting on support legs may have excess
vibration which can lead to premature wear and tear on fan components.
IMPORTANT: Electrical installation must be performed by a qualified electrician, in accordance with
National and Local Electrical Codes. Any violation of electrical wiring codes could
jeopardize the warranty.
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 on Page 16 of this manual.)
3. Verify that the safety disconnect is installed and sized correctly for the fan size. (See tables in
specification section on Page 16 of this manual.)
4. Install a machine to earth ground for each individual fan. Refer to ground rod installation on Page 14
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.
6. The starter controls require 115 VAC power to operate. On 230 volt 3 phase units, this power is
supplied by L1 to neutral.
1 PH 230V L1, L2, N, G
3 PH 230V L1, L2, L3, N, G
3 PH 230V with optional transformer kit L1, L2, L3, G
3 PH 460V/575V L1, L2, L3, G
DANGER
Always disconnect and lock out power before working on or around fan.
