INSTALLATION

IMPORTANT INSTALLATION INSTRUCTIONS

To reduce the risk of SEVERE INJURY or 

DEATH:

1. READ AND FOLLOW ALL INSTALLATION WARNINGS AND

INSTRUCTIONS.

2. Install door operator ONLY on properly balanced and lubricated the

door. An improperly balanced door may not reverse when required
and could result in SEVERE INJURY or DEATH.

3. ALL repairs to cables, spring assemblies and other hardware MUST

be made by a trained door systems technician BEFORE installing
operator.

4. Disable ALL locks and remove ALL ropes connected to the door

BEFORE installing operator to avoid entanglement.

5 Mount emergency release handle no higher than 1.8m above floor.

6. NEVER connect the door operator to power source until instructed

to do so.

7. NEVER wear watches, rings or loose clothing while installing or

servicing operator. They could be caught in the door or operator
mechanisms.

8. Install wall-mounted door control:

• within sight of the door.

• out of reach of children at minimum operator of  1.5 m.

• away from ALL moving parts of the door.

9. Place entrapment warning label on wall next to  door control.

10.Place manual release/safety reverse test label in plain view on inside

of the door.

11.Upon completion of installation, test safety reversal system. Door

MUST reverse on contact with a 50mm high object on the floor.

INSTALLATION STEP 1

Position the Opener

NOTE: 

For additional mounting options see accessories page.

1. Close the door completely.

2. Slide the operator with collar over the end of the torsion bar. Ensure

that the collar does not touch the bearing plate. Check to make sure
the mounting bracket is located on a solid surface such as wood,
concrete or door/flag bracket. Snug collar screws to help assure
proper alignment of operator. Mark the bracket holes. It may be
necessary to cut the torsion bar if it is too long or damaged.

3. Loosen collar screws from torsion bar and remove the operator. For

steel plate mounting use screws (1) provided. Drill 5mm pilot holes at
the marked locations. For concrete mounting use screw (2) 
and plugs.

4. Reinstall the operator by sliding the collar over the torsion bar until

pilot holes align with bracket. Securely tighten collar screws that
attach to the torsion bar to 16Nm-19Nm of torque. Securely tighten
both set screws firmly, without damaging the motor unit.

5. Fasten bracket securely with screws. Tighten all mounting bracket

hardware.

NOTE:

The motor unit does not have to be flush to wall.

To prevent possible SERIOUS INJURY or DEATH:

• Concrete anchors MUST be used if mounting bracket into masonry.

• NEVER try to loosen, move or adjust the door, springs, cables,

pulleys, brackets or their hardware, ALL of which are under
EXTREME tension.

• ALWAYS call a trained door systems technician if the door binds,

sticks or is out of balance. An unbalanced  door might not reverse
when required.

• Operator MUST be mounted at a right angle to the torsion bar to

avoid premature wear on the collar.

INSTALLATION STEP 2

Attach the Emergency Release Rope and
Handle

• Thread one end of the rope (1) through the hole in the top of the red

handle (2) so “NOTICE” (3) reads right side up as shown. Secure with
an overhand knot (4) at least 25mm from the end of the rope to
prevent slipping.

• Thread the other end of the rope through the loop in the emergency

release cable.

• Adjust rope length so the handle is no higher than 1.8m  above the

floor. Secure with an overhand knot.

NOTE: 

If it is necessary to cut the rope, heat seal the cut end with a

match or lighter to prevent unraveling.

INSTALLATION STEP 3

Install Power Door Lock

The lock is used to prevent the door from being manually opened

once the door is fully closed.

1. Select a door roller to mount the lock above. Check for clearance. If

possible select a roller on the same side of the door as the motor unit.

The second roller up from the bottom is ideal in most installations.

2. Ensure the door track surface is clean and adhere lock template with

bottom edge just above the highest point on the roller.

3. Drill holes as marked on the template (8mm).

4. Fasten power door lock to the outside of the door track with hardware

provided.

5. Run bell wire up wall to motor unit. Use insulated staples to secure

wire in several places.

6. Plug connector into the motor unit.

NOTE:

Lock must be mounted within 3m of the power head.
