INSTALLATION PROCEDURE

12
Do not allow people to walk under or around the
door during the installation process as serious
injury can occur.
NOTE: The opener can be installed on either side of the door.
The following instructions are for RIGHT HAND
INSTALLATIONS (as illustrated i.e. inside the garage looking
out). For left hand installations, reverse the instruction
terminology (eg LEFT for RIGHT etc).
Preparation:
• Place the opener in manual release mode (refer to section 10).
• Completely open the roller door. For safety, tie a rope around
the door.
• Ensure the door axle U-BOLT and door mounting bracket on the
left hand side (non opener side) are securely fastened.
• Support the door with a door stand, ladder or similar device to
safely support the door.
• Mark the position of the door shaft on the right hand door
bracket (for reassembly purposes).
• While the door is supported, remove the right hand axle U-Bolt
and door mounting bracket from the wall.
Install the opener:
• Slide the opener over the door axle and engage the drive legs
into the door drum wheel, either side of a spoke.
• Refit the door mounting bracket to the wall.
• Clamp the opener on the door axle and door bracket in the
marked position using the clamp assembly supplied (tighten to
25 – 28 Nm).
• Remove all ropes and the support stand.
• Check the operation of the door in manual mode by raising and
lowering by hand. It should operate smoothly without sticking or
binding. The disengage handle should already be attached less
than 1.8m above the floor (refer to section 9).
Connect the power:
• Position the power cable away from the door curtain and any
moving parts.
• Plug the opener into a nearby power point and turn ON.
• The opener light will turn ON and remain ON for 3 minutes.
