Attaching the Impeller
Improper installation of your impeller can lead to the impeller coming off
during operation. Significant damage to your system and/or bodily harm
can result. It is imperative that you read and follow these directions
closely. Detailed assembly videos can be found under the Education
Center/Assembly Instruction section of our website at
www.clearvuecyclones.com.
1. Remove the MDF packing plate affixed to the impeller and discard it.
2. Locate the taper-lock bushing (and screws). It will either be installed on the impeller, or packed in
a small box, inside of the materials box.
a. If the taper-lock is installed on the impeller, remove it by inserting the (3) taper-lock
bolts into the smaller, threaded holes in the bushing and tightening them down until
taper-lock releases from the impeller hub.
b. Pry the taper-lock slightly open by inserting a flat-head screwdriver into the slit.
3. Attach the taper-lock bushing to the impeller:
a. Insert the (3) taper-lock bolts into the
larger, non-threaded
holes in
the taper-lock bushing.
b. Slide the taper-lock into the hub in the center of the impeller, lining up
the taper-lock bolts with the
threaded
holes on the impeller.
c. Finger-tighten the bolts to secure them in place.
Make sure the taper-lock bolts are inserted through the larger, non-
threaded holes in the taper-lock bushing, into the threaded holes of the
impeller. The alternate set of holes is used for impeller removal only.
4. Position the impeller:
a. Slide the impeller onto the motor shaft, with the taper-lock bushing facing up.
b. Insert the motor key and lightly tighten the setscrew using a
3
∕
32
” hex key until it cannot
fall out.
c. For single phase motors, lift the impeller so that the taper-lock is flush with the top of the
motor shaft.
d. For three phase motors, lift the impeller so that the taper-lock sits ¼” below the top of
the motor shaft.
5. Tighten the taper-lock bolts:
a. Consecutively tighten each taper-lock bolt by a ¼
revolution, until they are all tight.
The tightening of each bolt will cause the subsequent bolts
to feel as if they’ve loosened.
b. Repeat this process until each bolt is torqued to the
manufacturer’s specification of 5 ft/lbs.
Upon completion, there should be a minimum of ¼”
clearance between the back of the impeller and the motor
bolts intalled in the motor plate. There may also be up to a
1

16
” –
1
∕
8
” gap between the taper-lock bushing and the impeller hub.
6. Firmly tighten the setscrew against the motor key using a
3
∕
32
” hex key.
