INSTALLATION INSTRUCTIONS
CHAIN HOIST INSTALLATION
1. If the operator is furnished with a chain
Hoist (Model H)Refer to Figure 5 to install
the chain hoist. Pass the hand chain, item
13 over the chain pocket wheel and through
the guide holes in the chain guard. Fasten
the ends of the chain together (to make one
continuous loop) by opening and re-closing
one link using two pairs of pliers. If the chain
is too long, shorten it to the desired length
by removing links.
2. Remove the sash chain from the shipping
bag and let hang from the disconnect lever.
Pull the sash chain to engage the hand
chain. This will de-energize the interlock
switch and remove power to the
operator.
3. Use lag screws to fasten the chain hoist
holding bracket furnished with the operator to
the wall vertically in line with the sash chain
about four feet off the floor. See Figure 5. This
bracket is also used to hold the release chain in
place for both the chain hoist equipped units
(H) and floor disconnect models (J).
BEFORE PROCEEDING WITH THE
OPERATOR INSTALLATION AND
SETTINGS, MAKE A FINAL CHECK FOR
TIGHTNESS OF ALL MOUNTING
HARDWARE AND SET SCREWS.
