• Turn the wheel by hand to ensure it turns freely and
does not bind.
• Inspect dampers for free operation of all moving parts.
• Record on the Delivery Receipt any visible sign of
damage.
Handling
Lift the fan by the base or lifting eyes. NOTICE! Never
lift by the shaft, motor, or housing.
Rotating Parts & Electrical Shock Hazard:
Disconnect electric power before working on unit.
Follow proper lockout / tagout procedures to ensure
the unit cannot be energized while being installed or
serviced.
A disconnect switch should be placed near the fan in
order that the power can be swiftly cut off, in case of
an emergency and in order that maintenance
personnel are provided complete control of the power
source.
Grounding is required. All field-installed wiring must
be completed by qualified personnel. All field-
installed wiring must comply with National Electric
Code (NFPA 70) and all applicable local codes.
Failure to follow these instructions could result in
death or serious injury.

Storage
If fan is stored for any length of time, prior to installation,
completely fill bearings with grease or moisture-inhibiting
oil. Refer to page 4. Store the fan in its original crate and
protect from dust, debris, and weather. To maintain good
working condition of a SQL when it’s stored outdoors, or on
a construction site follow the additional steps below.
• Cover the inlet and outlet, and belt tunnel opening to
prevent accumulation of dust and moisture in the
housing.
• Periodically rotate the wheel and operate dampers (if
supplied) to keep a coating of grease on all internal
bearing parts.
• Periodically inspect the unit to prevent damaging
conditions.
Installation
To prevent damage to the fan during shipping, motors 5
HP and larger, and extremely heavy motors (cast iron or
severe duty) are shipped loose and must be field mounted
by bolting the motor on the motor mounting plate in the
existing mounting slots.
Wiring Installation
NOTICE! All wiring should be in accordance
with local ordinances and the National Electrical
Code, NFPA 70. Ensure the power supply
(voltage, frequency, and current carrying
capacity of wires) is in accordance with the
motor nameplate. Refer to the Wiring Diagrams,
on page 3.
Direct drive - Wire the electrical box on the blower
housing.
Belt drive - The motor can be wired directly since the
motor is external to the fan.
