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 Figure 1) and secure to the motor platform. (A straight edge across the face of the driven pulley
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.

INSTALLATION
REQUIREMENT
Typical configuration shall be a SF air supply unit,
and a spun aluminum upblast exhaust fan. The
spun aluminum upblast exhaust fan should have a
base hinge and a grease collector.
As shown in Figure 3:
The bottom of the exhaust fan must be
18 inches away from the roof surface.
The outlet of the exhaust fan must be
40 inches away from the roof surface minimum.
AND
The inlet plane must be 10 feet away from the
outlet plane horizontally.
OR
The inlet plane must be 3 feet away from the
outlet plane vertically.
HOOD AND FILTER INSTALLATION
(Model SF10)
Attach duct section when required (by others) to the SF inlet flange. Drill 1/8” hole through duct and inlet flange and secure with metal
screws provided. Slide the hood (less filters) over the inlet flange and secure with the provided sheet metal screws.
HOOD/DUCT OVERLAP SHOULD NOT EXCEED 1”.
Remove hood cap and slide filter(s) into “U” channels located on the inner sides of the hood. Replace cap.
