SAFETYWARNINGS
IMPORTANT! PLEASE READ THESE INSTRUCTIONS CAREFULLY
PRIOR TO COMMENCE THE INSTALLATION OFTHE ORERATOR UNIT
This Automatic opener has been designed to provide years of trouble free use. The
opener will perform efficiently only if it is installed and operated properly.
READ THESE IMPORTANT SAFETY RULES FIRST
Keep garage door balanced. Sticking or binding doors must be repaired. Garage doors,
door springs, brackets and their hardware are under extreme tension and can cause
serious personal injury. Do not attempt adjustment. Call for professional garage
door service.
Do not wear rings, watches or loose clothing while installing or servicing a garage
door operator.
Installation and wiring must be in compliance with your local building and electrical
codes.
The safety reverse system test is very important. Your garage door must reverse on a
contact with a 5 to 10cm high object on the floor. Failure to properly adjust the
operator may result in serious personal injury from a closing garage door. Repeat the
test once a month and make adjustments if necessary. (see sensitivity adjustment).
KNR500 operator has an electronic obstruction system that provides safe and reliable
operation. It is however a legal requirement in some countries to also install a
Photo-electric sensor across the door way. Please check this requirement with your
local distributor.
Do not use the force adjustments to compensate for a binding or sticking garage door.
Excessive force will interfere with the proper operation of the Safety Reverse System
or damage the garage door.
This unit should not be installed in a damp or wet space.
Disengage all existing garage door locks to avoid damage to garage door.
Install the lighted door Control Box (or any additional Push Buttons) in a location
where the garage door is visible, but out of the reach of children. Do not allow
children to operate push button(s) or remote control(s). Serious personal injury from a
closing garage door may result from misuse of the operator.

CAUTION: Activate operator only when the door is in full view, free of obstructions
and properly adjusted. Do not enter or leave the garage while the door is in motion.
Do not allow children to play near the door.
Disconnect electric power to the garage door operator before making repairs or
removing covers.
IMPORTANT: Fix the caution label to the rear of the garage door as a reminder of
safe operating procedures.
PREINSTALLATION NOTE
N.B.: The right hand and left hand installation could be swapped if you wish.
Please refer to control box set up.
Check that there is sufficient side clearance to fit the operator unit. It may be fitted to
either the right or left hand side.

(1) Minimum side clearance
The minimum side clearance between door curtain and the inside edge of mounting
bracket is 85mm;
The minimum side clearance between door curtain and the outside edge of mounting
bracket is 135mm.
(2) Recommended side clearance
The recommended side clearance between door curtain and the inside edge of
mounting bracket is 110mm;
The recommended side clearance between door curtain and the outside edge of
mounting bracket is 160mm.
If the operator is being fitted at the same time as the new door installation, read these
instructions in conjunction with the KNR500 roller door installation instructions.
If the operator is being retrofitted, make sure the door operates smoothly and is
properly balanced.
N.B.: SPECIAL CARE SHOULD BE TAKEN IF RE-TENSIONING OF THE
DOOR IS REQUIRED.
At no stage should you loosen both “U”bolts if door is under tension.
IF THERE ARE ANY PROBLEMS PLEASE CONTACT YOUR LOCAL
SUPPLIER OFTHIS OPERATOR

INSTALLATION INSTRUCTIONS
STEP1
Whilst the door roll is on the floor, rotate shaft backwards and forwards by hand and
then release. This action will allow the roll to centralize itself on the shaft. (new
installation only).
STEP2
Slide drive unit onto shaft as shown figure 5, ensuring drive lugs engage fully with the
narrowest spoken on drum wheel.
N.B.: Right-hand installation shown (inside looking out)
Lift door onto mounting brackets (ensuring curtain roll is round in correct way)
centralize curtain roll with opening. Refer to door installation instructions. (new
installations only).
Ensure motor assembly is fully engaged with drum wheel spokes. Clamp shaft to
mounting brackets using “U”Bolts supplied. (use “U”bolt in opener pack for
MOTOR end). See Figure 6.

Disengage the motor drive by pulling the manual release string downwards. See
Figure6.
Tension door and complete door installation as per Door Installation Instructions.
Ensure door is correctly balanced and is not binding or sticking within vertical tracks.
Ensure locking bars (if fitted) are moved to the retracted (unlocked) position and keys
removed from the lock.
Mount Control Unit approximately 1.6m from the floor out of the reach of children.
Use NO.4×1”self-tapping screws and raw plugs supplied. Ensure aerial is clear of
all steel supports and coiled electrical leads. Fit plug from motor unit into bottom of
Control Box.
Connect the control unit power cord to an adjacent socket. Ensure that the socket is
properly earthed.
SETTING TOPAND BOTTOM LIMITS
N.B.: Right Hand Installation only. If left hand, limit switch will be reversed.
STEP1
Remove Limit Switch Cover Plate (See Figure 6) by carefully prising off with a small
screwdriver.
STEP2
Top limit cam “T”controls open position of door. Bottom limit cam “B”controls
closed position of door.
STEP3
Slightly loosen the three retaining screws so that the cams can be easily moved (See
Figure 7).

STEP4
Ensure that the manual release lever is still in the “disengaged”position, and
manually raise the door until it is approx 100mm from the top stop position.
STEP5
Rotate cam “T”(in the same direction that is moving as you were manually raising
the door), so that it actuates the top Limit Switch.
STEP6
Manually lower the door until it is touching the ground.
STEP7
Rotate cam “B”(in the same direction that is moving as you were manually lowering
the door) so that it actuates the bottom Limit Switch.
STEP8
Tighten the three retaining screws so that the cams will not move.
STEP 9
Manually position door to halfway and reengage the motor drive by moving the
manual release lever to the “engage” position.
N.B Door can now only be operated electrically, not manually. If you wish to return to
manual operation, ensure power is switched off and move lever to “disengage”
position.
IMPORTANT: When the door is travelling in the “Up” position, hold bottom rail.
The door should overload and stop. If it does not, reverse motor wires (Spade
Connections).
You will need to re-adjust the Limit Cams as they will be working in a different
direction.
STEP 10

Press Button on Control Box Front and check closing and stopping position.
STEP 11
If you are achieving the desired stop position, then replace the Limit Switch Cover
Plate. If not, then reset the Limit Cams (STEP 2 to 9) after first turning off the mains
power.
STEP 12
Once the limits have been set, fit the additional security screws (2 off self-tapping
screws supplied) with the door in manual mode. With the door fully closed, mark the
panel at the first point where the curtain roll touches the drum wheel on both ends of
the curtain (See figure 9).
Raise the door slightly so that the marks can be seen and accessed from inside the
garage.
Fit the security screws through the bottom of a corrugation and into the plastic flange
of the drum wheels , both ends of the curtain. Tighten securely.
WARNING! - Do not run door on power through its full travel until the limits
are correctly set.
