1. INSTALLATION INSTRUCTIONS SMART LIFT 236 Electric Ceiling Lift The Model SL 236 Electric Ceiling Lift is a reliable heavy duty video lift mechanism for LCD DLP projectors requiring an extended drop from their hidden location The ceiling lift is designed for home theater conference room or school applications The SL 236 provides an attractive solution to recess a projector in the ceiling The lift is suitable for finished or suspended ceiling with a finish kit The concealed bottom can be finished to match existing ceiling design and color to conform to room decor Plenum Rating requires use of Class II control wiring electrically hard wiring the unit and all open holes in the housing except joist tabs must be sealed using foil tape BEFORE YOU BEGIN e CAUTION To prevent damage to the ceiling lift which could affect or void the factory warranty thoroughly study all instructions and illustrations before you begin to install or operate the lift Pay particular attention to the Impor tant Precautions on Page 1 e CAUTION For smooth and reliable operation the lift must be installed square and parallel in all dimensions Avoid stressing or twisting the lift at any time during installation e Because of the size and weight of the lift Chief Manufacturing recommends that at least two people be available when installing the lift e If you have any questions concerning this installation contact Chief2. Avoid stressing the lift at any time during installation Instruction Manual SMART LIFT 236 Electric Ceiling Lifts Installation in a Suspended Ceiling using threaded rods You can suspend the lift housing from three 3 8 in dia threaded rods not supplied by Chief Manufacturing First secure the rods to a structural cross brace in the ceiling Insert the rods through the three holes on the top side of the lift housing or through the holes of optional brackets SMA 651 and secure them to the housing using two jam nuts one inside one outside See Fig 3 CAUTION For smooth and reliable operation the lift must be installed square and parallel in all dimensions Avoid stressing or twisting the lift at any time during installation THREADED ROD Install the lift using threaded rods 1 With the lift in the fully retracted position remove the closure panel from the bottom of the lift 2 If you are using the SMA 651 install it now 3 Insert the 3 threaded rods through the top of the lift or SMA 651 4 Using nuts and washers secure the lift to the threaded rods Finish the suspended ceiling 1 Cut the grid to fit the perimeter of the lift and insert it into the side channel of lift the side channel of the lift will support the Figure 3 Threaded Rod Installation weight of the ceiling grid and tiles 2 Ifusing the SMA 620 see the SMA 620 instructions and install them now 3 Cut sur
