BUSHING INSTALLATION

Install brass bushing in 13⁄32” diameter hole by sliding threaded end of bushing through the cover from front of cover so that the threaded end of the bushing is entirely on the inside of the cover (see illustra- tion of bushing in Figure 5). Fasten bushing with brass bushing nut supplied and tighten.

DAMPER HINGE INSTALLATION

Slide damper hinges onto damper as illustrated in Figure 3. Two hinges are supplied with damper for covers 31/2 ft. long and under, and three hinges are supplied for 4 ft. and over.

ATTACHING DAMPER TO COVER

1.Place cover on workbench or floor with inside of cover up and top of cover away from you against a stop.

2.Center damper over inside of Multi/Pak 90 or JA cover, approximately lining up the lead screw nut housing in the damper over the bushing in cover.

3.Slide one damper hinge so that it lines up between the first and second row of louvers at each end of the cover. The third hinge (if cover is 4 ft. or over) should be lined up between the two centermost rows of louvers.

4.Position top of each damper hinge so that it presses against inter- section of top of cover and cover top flange (see Figure 4).

5.Grasp damper firmly and lift as shown in Figure 4 and push damper towards the top of cover while rotating damper just enough to be able to snap bottom of damper hinge into space between the second and third louver blades of the first and second row of louvers.

6.Repeat for other damper hinges.

DAMPER KNOB AND LEAD SCREW

ASSEMBLY INSTRUCTIONS

1.Screw LEAD SCREW into LEAD SCREW NUT about 10 turns clock- wise in direction shown.

2.Line up LEAD SCREW with BUSHING hole by sliding DAMPER left or right.

3.Swing DAMPER toward COVER and guide LEAD SCREW through BUSHING hole until beginning of SCREW thread is against BUSHING and SCREW EXTENSION protrudes through front of COVER. Hold in place and proceed to step 4.

4.Place KNOB onto SCREW EXTENSION and line up Allen head SET SCREW in KNOB with FLAT of SCREW EXTENSION and tighten set screw with an Allen wrench.
