ROLLER DOOR OPENER MANUAL
MODEL: YHDO-1

SAFETY WARNINGS
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE COMMENCING THE INSTALLATION OF THE ORERATOR UNIT
This Automatic opener has been designed to provide years of trouble-free use. However, it will only perform efficiently if installed and operated correctly.
READ THESE IMPORTANT SAFETY RULES FIRST
Keep the garage door balanced. Sticking or binding doors must be repaired. Garage doors, door springs, brackets, and 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 comply with your local building and electrical codes.
The safety reverse system test is critical. Your garage door must reverse when it contacts a 5—to 10-cm-high object, which may result in serious personal injury from closing it. Repeat the test once a month and make adjustments if necessary (see sensitivity adjustment).
YHDO operator is an electronic obstruction system that provides safe and reliable operation. However, some countries also require the installation of a photoelectric sensor across the doorway. 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 be installed in a damp space.
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). Misuse of the operator may result in serious personal injury from a closing garage door.
⚠️ CAUTION
Activate the 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, and do not allow children to play near it.
Disconnect the electric power to the garage door operator before repairing or removing covers.
IMPORTANT: Fix the caution label to the rear of the garage door to remind drivers of safe operating procedures.
PREINSTALLATION NOTE

N.B: The right-hand and left-hand installations could be swapped if you wish. Please refer to the control box setup.
Check that there is sufficient side clearance to fit the operator unit. It may be fitted to either the right or left-hand side.
-
Minimum side clearance
The minimum side clearance between the door curtain and the inside edge of the mounting bracket is 85mm. The minimum side clearance between the door curtain and the outside edge of the mounting bracket is 135mm.
-
Recommended side clearance
The recommended side clearance between the door curtain and the mounting bracket is 110mm. The recommended side clearance between the door curtain and the mounting bracket is 160mm.

f the operator is being fitted at the same time as the new door installation, read these instructions in conjunction with the YHDO 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 the door is under tension.
IF ANY PROBLEMS, PLEASE CONTACT YOUR LOCAL SUPPLIER OF THIS OPERATOR.
GARAGE ROLLER DOOR OPENER INSTALLATION INSTRUCTIONS
STEP 1
Whilst the door roll is on the floor, rotate the shaft backwards and forwards by hand and then release. This action will allow the roll to centralize itself on the shaft. (New installation only).
STEP 2
Slide the drive unit onto the shaft as shown in Figure 5, ensuring the drive lugs engage fully with the narrowest spoke on the drum wheel.

N.B.: Right-hand installation shown (inside looking out)
Lift the door onto the mounting brackets (ensuring the curtain roll is round correctly) and centralize the curtain roll with the opening. Refer to door installation instructions. (New installations only).
Ensure the motor assembly is fully engaged with the drum wheel spokes. Clamp the shaft to the mounting brackets using the “U” bolts supplied. (Use the “U” bolt in the opener pack for the MOTOR end.) See Figure 6.
Disengage the motor drive by pulling the manual release string downwards. See Figure 6.
Tension the door and complete the installation as per the Instructions. Ensure the door is correctly balanced and does not bind or stick within the vertical tracks.
Ensure locking bars (if fitted) are moved to the retracted (unlocked) position and keys removed from the lock.
Mount the Control Unit approximately 1.6m from the floor out of the reach of children. Use the NO.4×1” self-tapping screws and raw plugs supplied. Ensure the aerial is clear of all steel supports and coiled electrical leads. Fit the plug from the motor unit into the bottom of the Control Box.
Connect the control unit power cord to an adjacent socket. Ensure that the socket is properly earthed.
SETTING TOP AND BOTTOM LIMITS
N.B.: Right-hand installation only. If the left-hand limit switch is reversed.
STEP 1
Remove the Limit Switch Cover Plate (See Figure 6) by carefully removing it with a small screwdriver.
STEP 2
The top limit cam, “T,” controls the door’s open position, and the bottom limit cam, “B,” controls the door’s closed position.

STEP 3
Slightly loosen the three retaining screws
so that the cams can be easily moved (See Figure 7).
STEP 4
Ensure that the manual release lever is still in the “disengaged” position, and manually raise the door until it is approximately 100mm from the top stop position.
STEP 5
Rotate cam “T” (in the same direction it was moving when you manually raised the door) to actuate the top Limit Switch.
STEP 6
Manually lower the door until it is touching the ground.
STEP 7
Rotate cam “B” (in the same direction it was moving when you manually lowered the door) to actuate the bottom Limit Switch.
STEP 8
Tighten the three retaining screws so that the cams will not move.
STEP 9
Manually position the door halfway and re-engage the motor drive by moving the manual release lever to the “engage” position.
N.B. The Door can now only be operated electrically, not manually. If you wish to return to manual operation, ensure the power is switched off and move the lever to the “disengage” position.

IMPORTANT: Hold the bottom rail when the door travels in the “Up” position. The door should overload and stop. If it does not, reverse motor wires (Spade Connections). You must re-adjust the Limit Cams as they will be working in a different direction.
STEP 10
Press the Button on the Control Box Front and check the closing and stopping position.
STEP 11
If you achieve the desired stop position, replace the Limit Switch Cover Plate. If not, 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 the marks can be seen and accessed inside the garage.
Fit the security screws through the bottom of the corrugation and into the plastic flange of the drum wheels at both ends of the curtain. Tighten securely.
⚠ WARNING! – Do not run the door on power through its full travel until the limits are correctly set.

CONTROL BOX SET UP
Remove the cover on the front of the control box.
