INSTALLATION & MAINTENANCE INSTRUCTIONS

MODEL DXP

WARNING! Do not use fans in hazardous environments where the fan’s electrical system could provide ignition to

combustible flammable materials, unless built specifically for that environment. This unit has rotating parts and safety
precautions should be exercised during installation, operation and maintenance.

Remove from shipping crate prior to installation. All debris and shipping material must be removed to prevent obstruction
of airflow to and from the orifice. The orifice opening on both sides must be kept clear of obstructions. Failure to keep
the orifice opening clear could cause undue stresses on the propeller blades, damage to the fan, and unsafe operation
condition.

WARNING! Check voltage being supplied to fan to see that it corresponds with the motor nameplate voltage; high or low voltage can
seriously damage the motor. On multi-voltage motors check motor terminal connections to make sure motor is internally connected for
voltage being supplied. Motor wiring diagram is located on the side of the motor or in the motor wiring compartment. Leave enough
slack in wiring to allow for motor movement when adjusting belt tension.

Fans with elliptical diffusers can be mounted on

67.50 inch centers.

BELT TIGHTENER MAINTANENCE

CAUTION: Before proceeding, make sure electrical service to fan is locked in “OFF” position.

1. If the belt stretches enough that the belt tightener does not keep the belt tight, the belt tightener
can be adjusted. Start by loosening the 3/8 inch bolt holding the belt tightener to the belt tightener
base.

2. Place a wrench on the hex nut in the belt tightener body as shown in Figure 3 and a wrench on
the belt tightener mounting fastener.

3. Using the wrench on the belt tightener body, apply pressure in the appropriate direction (see
Figure 3) until the belt is properly tensioned. Note: The belt tightener body has marks on it as
shown in Figure 4 representing degrees. The proper alignment after tightening the mounting bolt
is shown in Figure 5.

4. With the belt tightener securely held in position, tighten the belt tightener mounting bolt.
