CHAIN HOIST AND FLOOR DISCONNECT
INSTALLATION
If the operator is furnished with a chain hoist (Model H-S), pass the
hand chain over the chain wheel and through the chain guides on
the operator clutch shaft (opposite end from the large pulley).
Fasten the ends of the chain together by opening and re-closing one
link using two pairs of pliers. If the chain is too long (standard
length for 16 foot high doors and below is 26 feet total length of
chain), shorten it to the desired length using the method described
above and discard the unused portion.
Fasten the chain hoist holding bracket furnished with the operator
to the wall approximately four feet from the floor. This bracket is
also used to hold in place the release chain for both the chain hoist
equipped units (Model H-S) and floor disconnect models (Model
J-S).
