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.

PACKING LIST

NOTE: Chain hoist shown on right, drive shown on left.

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

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.

FIGURE 26. 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. It is necessary to have chain at the floor end of the cable so that the hand chain engagement mechanism can be locked down with the chain retaining bracket.

CHAIN HOIST INSTALLATION

1. Determine location for the hand chain assembly. Slide the 1" shaft collar on the shaft, reworked side toward the end of the shaft, and tighten down.

2. Starting against shaft collar, slide the chain guide on the end of the shaft collar that has been reworked. Slide the chain wheel assembly on next.

3. Install (2) 5/16" x 1" long roll pins in the holes in the chain wheel hub.

4. Drill a 5/16" hole next to the hub on the chain wheel assembly and install a 5/16" x 2-1/2" roll pin. Do not make the assembly too tight. Thick and thin washers are provided to take out extra slack or to allow more movement.
