4. PRE-INSTALLATION RECOMMENDATIONS
Please complete the following test under no other force than the torsion force of the door
spring to ensure correct balance of the door:
1. Raise and lower the door to determine whether there are
any sticking or binding points. (20kg is the absolute maximum
allowable to raise or lower the door in any position).
2. Do not lock the roller door or remove any rope connected
to the roller door.
3. Lift the door about halfway up and then release it.
The door should be balanced by the spring rebound.
4. If the roller door is not correctly balanced in place, consult
a qualied roller door installation technician before installing the motor.
5. ATTACHING THE WEIGHT BAR
1. If the door has a lifting handle, remove the handle, nuts and bolts. Place the weight bar
over the handle holes, insert the extended bolts through the weight bar, and fasten the
handle back in place.
2. It is important to place the weight bar in the centre of the door as shown.
3. If the door curtain does not have a handle, place
the weight bar in the middle position below the inside
of the door, and use the marker pen to draw two holes
through the screw holes.
4. Drill two holes with a 6.5mm drill bit.
5. Use the bolts, washers and nuts provided
to fasten the weight bar in place.
Note: This motor should not be installed in a damp space or be exposed to the outdoors.
After installation of the roller door, ensure that no part of the roller door extends over public areas
or the pavement. The motor should not be installed on a roller door with a pass-door.
