Chain Couple - Genie GCL-J&H Installation Manual

Chain Couple

The Side Mount Operator can be assembled for right or left hand
mounting above or below the door shaft and is available with or
without hoist.
If you will be using the Tension Plate Kit shown on page 4.4, slide the
bearing plates on the operator output shaft. Assembly of the kit will be
done after the drive chain is installed.
1) Attach the operator sprocket to operator output shaft.
2) Align keyways and insert key into sprocket. Do not tighten set
screw at this time.
3) Attach sprocket to door shaft.
4) Align keyways and insert key into sprocket. Do not tighten set
screw at this time.
5) Assemble chain using chain connecting link.
6) Place assembled chain over door shaft sprocket.
7) Raise or lower operator to remove slack from the chain.
8) Be certain operator output shaft is parallel with door shaft.
9) Align chain and secure operator to wall or mounting pad. Fig. 2.
10) Tighten operator sprocket set screws.
INSTALLATION TIP:
While sprocket set screws are loose, if possible, manually operate
door to help align chain. A properly tensioned drive chain should deflect
no more than 1/2" when thumb pressure is applied mid-way between the
2 sprockets. While there is no hard and fast rule governing chain tension,
it must be tight enough to prevent clicking, popping and jumping the
teeth of the sprocket. The 1/2" guideline will insure sufficient tension.
