PRE-INSTALLATION NOTES
The operator may be fitted to either the RIGHT or LEFT hand side of the roller door. Check that there is sufficient side clearance to fit the operator unit as below listed:
| Door Type | Minimum Side Clearance |
| “A” Series (25mm deep tracks) | 90mm |
| “AA” Series (50mm deep tracks) | 115mm |
| All doors with Windlok Tracks subject to Drum Position | 140mm |
Ensure there is a property earthed mains supply socket adjacent to where the operator is to be fitted.
If the operator is being fitted at the same time as the new door installation, read these instructions in conjunction with the door installation instructions.
If the operator is being retro-fitted, make sure the door operates smoothly and is properly balanced.
N.B.: SPECIAL CARE SHOULD BE TAKEN IF RE-TENSIONING OF THE DOOR IS REQUIRED.
At no stage should you loosen both “U” bolts if door is under tension.
