INSTALLING WITh AN LTA 2.0, 3-5 FT. TELESCOPIC ARM

(continued)

MOUNTING THE MOTOR-MOUNTING BRACKET AND TELESCOPIC ARM

(continued)

Remount the telescopic arm on the telescopic mount- ing bracket by sliding the friction block over the post of the bracket and securing with the 1.75” bolt and nut (Refer to Figure 10).

MOUNTING THE EXTRACTION FAN TO THE MOTOR MOUNTING BRACKET

Position the tapered connection flange (Fig. 14C) on the motor mounting brackets; use the (2) 0.75” and

(2)2.5” bolts with washers (supplied with the fan) to secure the fan (Fig. 14B) and the connection flange to the motor mounting brackets. Tighten all bolts secure- ly to make a good seal on the inlet of the fan.

ADJUSTING THE FRICTION POSITIONING

The amount of friction resistance should be set such that the arm is comfortable to move (always test both up and down movements), yet hold its position against gravity once positioned.

To adjust the friction resistance of the hood move- ment, fold back the rubber band onto the hood, and push up the flexible hose, exposing the connection blocks. Use an 8mm wrench to adjust both bolt/nut pairs as shown in Fig. 15.

Position one of the 8” rubber seals supplied with the arm on the largest part (8” diam.) of the tapered con- nection flange. Roll the bottom of the rubber seal up, and slide one end of the 4 ft. connection hose (sup- plied with the arm) up over the tapered connection flange until it butts up against the folded side of the rubber seal. Fold the rubber seal down over the hose. Secure the connection with one 8” hose clamp. Apply the other 8” rubber seal and the other end of the hose to the top of the telescopic arm tube.

The K1494-2 Starter/Overload Switch or K1669-2 Lamp Kit must be installed to provide power to the fan. Refer to the appropriate Installation section in this manual for details.
