SMART-LIFT Electric Ceiling Lifts

Installation in a Wood Framework (or Side-Mounted to Joists)
The lift housing has joist tabs to assist in side-mounting the
lift to the ceiling joists or otherwise securing it to a wood
framework.
For this method, you should first construct any framework
and secure it to the joists, then install the lift as outlined
below:
1.
Using the same jumper wire and push button used for
pretesting (page 2), cycle the lift to its “open” position.
This allows access to the inside of the housing and
exposes the mounting tabs.
WARNING: Plenum rating requires hardwiring through the
provided strain relief, use of Class II control wiring, and all
open holes in housing (except joist tabs) must be sealed using
foil tape. See wiring instructions in this manual and follow all
local building and electrical codes.
2.
If you need more space for access to the mounting tabs,
remove the ceiling pan:
a.
Remove the four plugs, one at each corner of the pan
(See Fig. 5), to reveal four small screws.
b.
Using a #1 Phillips screwdriver, remove the four
screws and remove the ceiling pan.
NOTE:
The ceiling-pan screws are primarily used only
for removing the pan if there is an electrical problem and
the lift can’t be cycled open.
3.
Secure the lift to the joists or wood framework. At least
six 1/4 x1-1/4-in. lag screws must be driven through the
mounting tabs around the inside of the lift housing.
There are 10 tab locations, three in each side and two in
each end. Refer to Fig. 5 and Fig. 6. The lift only
requires support on two opposing sides.
4.
Install the ceiling pan and secure the ceiling pan using
four screws.
CAUTION:
For smooth and reliable operation, the lift
must
be
installed square and parallel in all dimensions. Avoid stressing the
lift at any time during installation.
After installing the lift, use the test push button to carefully
operate the lift all the way up and down to be sure the clear-
ances are adequate.
