Before insulating the duct work, check for proper damper opera- tion. Apply the 24vac between COM and OPN to open the damper and COM and CLS to close the damper. (See Fig. 7.) The damper will modulate counter-clockwise to open and clockwise to close.

If in an emergency it becomes necessary to force a damper open, manually press in the red quick blade release button with one hand and turn the mounting hub to reposition the damper shaft. Release the button to hold the damper shaft in the new position.

To avoid noise and vibration, do not hard mount dampers to any solid structure such as joists.

ROUND METAL DUCT WORK

IMPORTANT: If application exists with all metal duct work without insulation, flex connectors must be used on each end of zone dampers to avoid noise and vibration.

1.Crimp end of branch duct.

2.Slip end of zone damper over end of duct work. Use self-tapping sheet metal screw to secure. (See Fig. 8.)

3.Properly seal joint using duct tape, mastic, or other approved method. Do not allow mastic to come in contact with actuator.

4.Insulate damper using 1-1/2-in. to 2-in. insulation. (Check your local codes.)

NOTE: All zone dampers and duct work must be properly supported according to local codes or SMACNA standards.

RECTANGULAR METAL DUCT WORK

1.Make connections using S-lock and drives. (See Fig. 10.)

2.Properly seal joint using duct tape, mastic, or other approved method. Do not allow mastic to come in contact with actuator.

3.Insulate damper using 1-1/2-in. to 2-in. insulation. (Check your local codes.)

NOTE: All zone dampers and duct work must be properly supported according to local codes or SMACNA standards.

NOTE: There should be a minimum of 4 ft between zone damper and first branch duct if more than 1 branch duct is downstream of zone damper.

ROUND FLEXIBLE DUCT WORK

1.Slip 1 end of flexible duct work over 1 end of zone damper. (See Fig. 12.)
