Mount the fan blade onto the fan shaft. Loosen the
two bolts on the fan blade prior to attaching. When
mounted, hand tighten these bolts. After final
alignment is established these bolts will be tightened
further.
STEP 5
Attach the two Pillow Block Bearings using M10x40
(4) to the shaft bracket. Insert the fan shaft into the
two pillow block bearings. The shaft should protrude
slightly longer on the front of the fan vs. the back of
the fan where the large pulley attaches.
STEP 4
Connect the shaft bracket (plate that is approx. ½
the width of motor mounting bracket) below the
motor mounting bracket, directly above the
mounting plate, using M8x40 (4).
STEP 3
Connect the motor bracket (plate with the oval
cut-out center) in between the two uprights centered
in the top of the frame, using M8x40 (4). Please
notice the flat mounting plate should be on the
bottom of the frame. See
Diagram 3.
STEP 2
Attach the large pulley to fan shaft on the opposite
side of the fan blade. Be certain the center of the
large pulley is aligned straight up with the large oval
of the motor bracket. Once alignment is established
tighten two set screws on the large pulley.
See
Diagram 4.
STEP 6
The fan blade needs to be aligned with the orifice
opening so the blade edge does not stick past the
edge of the orifice. Once aligned, tighten the set
screws.
STEP 7
Mount the Tensioner bracket on the back right side
of the shaft mount using M8x25 (2).
See
Diagram 5.
