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.
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.

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.
