5. Adjust and set the vibration isolators to correct operational height – (for further details, see spring vibration isolator
assembly instructions – page 6).
6. Once the fan inlet sleeve and isolation damper sleeve are aligned, (there should be about a 4” gap between the two
sleeves), attach the PVC flexible connector. The flexible connector, when attached, should have some slight slack
to it. A set of stainless steel adjustable straps are included with the connector for attaching to both sleeves.
7. When the vibration isolators are in the correct location, drill 5/16” dia. pilot holes through the anchorage slot holes of
the isolators to about 1” depth.
8. To prevent water penetration, fill in the entire pilot hole with a waterproof, external grade silicone caulk.
9. Secure the isolators down with 2” long by 1/2” dia. self-tapping steel lag screws. Some of the caulking will be forced
out of the hole to form a barrier around the fixing.
10. Finally, caulk all around the base of the isolators to form a complete watertight seal.
Refer to Fig. 3 & Fig. 4 for the following instruction.
1. Mount the isolators on the Axijet fan isolation support bracket (this bracket is only available on steel Axijet fans, on
FRP Axijets the isolators will be mounted onto isolator holes on the underside of the fan stand).
2. Place the fan isolator assembly on the fan rails section. The centerline of the fan’s isolation rails should line up with
the centerline of the 8” wide fan rails – (see Fig No.4). Please refer to the ‘Equipment Support Detail’ drawing that is
part of the submittal for further details.
3. Place the plenum on top of the plenum curb.
4. Line up the fan inlet with the isolation damper inlet transition, (round collar/sleeve), which is attached to the plenum.
