APPLICATION

This modification is available for model GH operators. For use on

sectional doors only.

FUNCTIONS

This allows emergency hoist access to either side of the door.

Must be factory supplied with operator.

PREPARATION

We have set up the handing of the chain hoist based on your

order. If you find due to the job conditions that the chain hoist

needs to be on the opposite side of the operator, it can be moved.

If this is the situation, do this modification before mounting the

operator. Refer to the operator owner’s manual.

INSTALLATION

1. Install the driven sprocket on the door shaft and mount the

operator based on the location of this sprocket. If necessary

cut the unused side of the hand chain shaft off so that the drive

chain does not interfere with the operator mechanism.

2. This kit includes a length of cold rolled 1" shaft that is half the

door width plus 2' based on a center mounted door operator.

Be sure that this is long enough for your application. If not,

secure a longer shaft before continuing. Install the 48B14

sprocket provided on the end of the shaft by drilling a 1/4" hole

through the sprocket and shaft and secure with the 1/4" by

1-1/2" long roll pin provided. Be sure that the shaft does not

extend past the end of the sprocket and that the teeth of the

sprocket are at the end of the shaft (Figure 2).

To prevent possible SERIOUS INJURY or DEATH, disconnect

electric power to operator BEFORE installing.

ALL installations and electrical connections MUST be made by

a qualified individual.

WARNING

CAUTION

WARNING

3. Raise the shaft and sprocket assembly into position so that this

sprocket is butted against the sprocket on the operator hand

chain shaft and support the shaft temporarily. Use the piece of

#40 chain provided to connect the two sprockets together.

4. Slide bearing onto the shaft and securely mount it so that the

shaft turns freely without binding.

5. Use the instructions below to complete the assembly of the

chain hoist.

6. Cut off the excess shaft if necessary but allow for another bearing on the outside of the chain hoist to support the load when the hoist is used. 7. Install the second bearing. 8. Cut the disconnect sash chain close to the operator and splice in the cable provided with a cable clamp (provided). Run the cable through screw eyes and down the wall under the chain hoist. Use the other cable clamp to reattach the sash chain to this cable.
