GENERAL SAFETY

Rotating parts, (pulleys, shafts and belts) on fans should not be exposed. Where these components are not protected by ductwork, cabinets

or covers, appropriate guards should be employed to restrict exposure to rotating parts. Access doors should not be opened with the fan

operating to avoid foreign objects being drawn into the system. On initial start-up, a careful inspection should be carried out to ensure no

foreign material is present which could become airborne in the system.

Read installation and operation instructions carefully before attempting to install, operate or service NAKS SF Series Blowers. Failure to

comply with instructions could result in personal injury and/or property damage. Retain instructions for future reference.

BEFORE YOU BEGIN

Inspect unit for damage, report any shipping damage to carrier. Check all fasteners, re-tighten as required. Rotate the blower wheel by

hand to ensure free rotation. If rubbing occurs, loosen the set screw(s), re-position the wheel to the shaft center, re-tighten set screws.

INSTALLATION

Remove hood and filters from inside the cabinet. Caulk top of curb before setting unit in place. (Curb must be smaller than unit “A”

dimension). Secure unit to curb through holes located around the bottom of the unit. Tighten wheel set screw.

MOTOR, PULLEYS & BELTS (See Table next page)

1. Mount the blower pulley on the blower shaft and tighten the set screw securely on the key of the shaft.

2. Mount the motor pulley on the motor shaft. Leave some clearance between the pulley and the motor end bell. Tighten the set screws

on the key of the motor shaft.

3. Install the motor on the motor platform using the hardware provided.

4. With the platform in its minimum position, install the V-belt within the pulley grooves. Position the motor on the motor platform to

ensure proper pulley alignment (see ) and secure to the motor platform. (A straight edge across the face of the driven pulleyFigure 1

should be parallel to the belt once proper alignment has been achieved).

Note: Adjustments in the variable speed pulley require pulley re-alignment.

*Curb size to be smaller than inside cabinet to allow for ﬂashing and rooﬁng.

**Includes ﬁlter section

5. Pivot the motor platform to tension the V-belt and lock in place using the 2 bolts on both sides of the blower. (Ideal belt tension

is the lowest tension at which the belt will not slip during start up.) As shown in illustration to right, a proper deflection of 1/64 of

the belt span is desired for belt tension.

WARNING

EXCESSIVE BELT TENSION IS THE MOST FREQUENT CAUSE OF BEARING WEAR AND RESULTING NOISE.

PROPER BELT TENSION IS CRITICAL FOR QUIET EFFICIENT OPERATION.

Ideal belt tension is the lowest value under which belt slip will not occur at peak load conditions.
