Keep garage door balanced. Do not let the garage door opener compensate for a binding or sticking garage
door. Sticking, binding or unbalanced doors must be repaired before installing this opener.
Do not wear rings, watches, loose clothing while installing, or servicing a garage door opener. Wear gloves,
safety goggles and suitable protective clothing where appropriate.
Frequently examine the door installation, in particular cable, springs and mountings for signs of wear,
damage or imbalance. Do not use if repair or adjustment is needed since springs and hardware are under
extreme tension and a fault can cause serious personal injury.
To avoid serious personal injury from entanglement, remove all ropes, chains and locks connected to the
garage door before installing the door opener.
Installation and wiring must be in compliance with your local building and electrical codes.
Before performing any repairs or removing covers, the door opener should be separated from the electric
supply. The repairs and electrical installation may be performed only by an authorized electrician.
As a rule, fuses are rated according to the power rating of the appliance. If you have to replace a fuse, it is
essential, having checked and corrected the reason for the fuse blowing, to replace it only with another of the
same rating. The garage door opener GB (UK, NI) plug is fi tted with a 3A (BS1362) fuse.
The safety reverse system test is very important. Your garage door MUST reverse on contact with a 40mm
obstacle placed on the fl oor. Failure to properly adjust the opener may result in serious personal injury from a
closing garage door. Repeat the test once a month and make any necessary adjustments.
Use the Manual Release only for the separation of the carriage from the drive and – if possible – ONLY with
the door closed. Do not use the red handle to push the door up or pull it down. Operation of the emergency
release can lead to uncontrolled movements of the door, if springs are weak or broken or if the door is
unbalanced. Mount the release handle of the emergency release at a height less than 1.8m from the fl oor.
The Protector System™ must be used for all installations where the closing force as measured on the
bottom of the door is over 400N (40kgf). Excessive force will interfere with the proper operation of the
