Chapter 3: Getting Started

Removing these fasteners allows you to rotate the housing

to one of the other desired outlet positions. Then insert the

8 fasteners and secure the blower housing in that specific

position.

3. Reinstall the upper weathercover panel and you are ready

for operation.

CAUTION: Blower 7071900 must be installed

with outlet positioned for upward discharge.

This will ensure that the integral back draft

damper assembly will work properly. The

dampers close by gravity when the blower is

turned off and the blower needs to be in the

proper orientation for this to occur.

Install the Exhaust Run with

Vibration Dampers

Rubber isolation sleeves should be used in your exhaust duct run

prior to entering the blower inlet. These isolation sleeves dampen

vibration that is being generated by the blower and decrease noise

level at the fume hood. See the flexible duct connections listed in

Chapter 7.

Connect to the Blower Inlet for

Coated Steel Blowers

Coated Steel Blowers model numbers 7068000 through 7068700,

feature a 10-7/8" ID by 1-1/2" wide circular inlet ring. This inlet

ring is suitable for use with 10-inch diameter PVC ductwork. The

PVC ductwork itself will fit inside the inlet ring and should be

fastened by sheet metal screws through the inlet ring. A silicone

sealant should also be used to seal between the ductwork and the

blower inlet ring to prevent any air or moisture leakage.

Coated Steel Blowers, model numbers 7068800 through 7069700,

feature a 12-1/4" OD by 1-1/2" wide inlet ring, which is suitable

for use with 12-inch diameter PVC ductwork. The 12-inch

diameter PVC ductwork will fit over the inlet ring on the blower

and should be fastened in position by sheet metal screws into the

metal ring.
