Maintenance
Motor maintenance is generally limited to cleaning and lubrication (where applicable). Cleaning should be limited to
exterior surfaces only. Removing dust buildup on motor housing ensures proper motor cooling. Greasing of motors
is only intended when fittings are provided. Many fractional motors are permanently lubricated and should not be
lubricated after installation. Motors supplied with grease fittings should be greased in accordance with manufacturer’s
recommendations. With motor temperatures under 104ºF (40ºC), the grease should be replaced after 2000 hours of
running time as a general rule.
Wheels require very little attention when moving clean air. Occasionally, oil and dust may accumulate causing
imbalance. When this occurs, the wheel and housing should be cleaned to ensure smooth and safe operation.
All fasteners should be checked for tightness each time maintenance checks are performed prior to restarting unit.
A proper maintenance program will help these units deliver years of dependable service.

Pre-Starting Checks
Check all fasteners for tightness. The
wheel should rotate freely and be aligned
as shown in Fig. 3. Wheel position is
preset and the unit tested at the factory.
However, movement may occur during
shipment, and realignment may be
necessary. Centering (height alignment)
may be accomplished by loosening the set
screws in the wheel and moving the wheel
to desired position.
Overlap 1/4 in.
Gap 1/8 in.

Installation
Move fan to desired location and determine position of access panels, discharge, and motor. Make sure inlet and
outlet have at least 2.5 times the wheel diameter (duct diameter) before any obstructions like an elbow or transaction.
Attach fan to suitable framework as specified (hanging or base vibration isolators are recommended). See chart below
for dimensions of vibration isolator centerlines (Fig.1). See Fig. 2 for physical dimensions.
The voltage rating of the motor 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.

Wheel Rotation
Direction of wheel rotation is
critical. Reversed rotation will
result in poor air performance,
motor overloading and possible
burnout. Check wheel rotation
(all XID fans have CW wheel
rotation when viewed from top
of fan) by momentarily energizing the unit.
Rotation should be clockwise as shown in Fig. 4 and
correspond to the rotation decal on the unit.
