IMPORTANT SAFETY INSTRUCTIONS FOR
INSTALLATION
Warning: Incorrect installation can lead to severe injury.
Follow ALL installation instructions.
CHECK OPERATION OF DOOR
BEFORE BEGINNING THE INSTALLATION OF THE
SECURALIFT
®
AUTOMATIC OPENER CHECK THE
OPERATION OF THE DOOR.
The door must be well balanced and be in a reasonable
operating condition. You should be able to lift the door
smoothly and with little resistance. It should stay open around
900mm to 1200mm above the floor. The door should not stick
or bind in the guide tracks. The ideal operational effort in
raising or lowering the door should not exceed a force of 10kg
(22 lbs.). Make sure that all door locks are either released, or
disabled and remove unnecessary accessories.
STEP 1
Slide shuttle assembly onto tube (one piece only) and locate it
in approximately half way position.
Please note:
Arrow on shuttle must point towards garage door.
To assemble the rest of the tubes, always slide short insert tube
half way into the long tube, then slide other tube onto
remaining portion of insert tubes. Continue this process with
remaining tube until desired length is achieved.
STEP 2
The opener is supplied with a 10 teeth drive sprocket on drive
unit. If the opener is to be fitted to a one piece door without
track, exchange the 10 teeth sprocket on drive unit, with a 7
teeth drive sprocket available as an option from ATA.
IMPORTANT:
If using a track type door (often referred to as
a sectional or track tilt door) use only 10 teeth drive sprocket on
the drive unit. If using a one piece door without tracks use the
7 teeth sprocket on drive unit.
STEP 3
Attach one end of chain (supplied) to chain index screw,
nearer to drive unit, using one joint link. (
Fig. 3
).
Proceed to wrap chain around drive unit sprocket/idler wheel
then follow along the pipe to the idler wheel on support pipe
assembly, finally attach to the other end of the chain index
screw.
NOTE:
Make certain that teeth of drive unit sprocket are
engaged in the chain and that the chain is not twisted. Make
sure that the chain is engaged in the plastic chain idle wheel on
the support pipe assembly.
STEP 4
Disengage trolley from chain index by swinging lever
downward (
Fig. 4
), then slide trolley away from chain index
along pipe track. Loosen locking nuts on chain index screws. To
tighten chain, turn chain index in anti-clockwise direction,
looking from support pipe assembly to drive unit. Do not over-
tighten chain as it has to sag 6-12mm. Check before locking
screw with locking nuts that chain is not twisted. When the
tension is finalised, tighten lock nuts at both ends of chain
index.
