Planning • The torsion bar must extend at least 1" to 5" (2.5 cm to 12 cm) past the bearing plate. • An electric outlet is required within 6' (1.8 m) of the installation area. If outlet does not exist, contact a qualified electrician. • Depending upon building construction, extension brackets or wood blocks may be needed to install safety reversing sensors. • Alternate floor mounting of the safety reversing sensors will require hardware not provided.
Preparing your Door Before you begin: • Disable locks. • Remove any ropes connected to door. • Complete the following test to make sure your door is balanced and is not sticking or binding: 1. Lift the door about halfway as shown. Release the door. If balanced, it should stay in place, supported entirely by its springs. 2. Raise and lower the door to see if there is any binding or sticking. If your door binds, sticks or is out of balance, call a trained door systems technician. 3.
Carton Inventory Note that accessories will depend on the model purchased. If anything is missing, carefully check the packing material. Your door operator is packaged in one carton which contains the motor unit and the parts illustrated below.
ASSEMBLY STEP 1 Attach the Collar to the Operator To prevent possible SERIOUS INJURY or DEATH, the collar MUST be properly tightened. The door may not reverse correctly or limits may be lost due to collar slip. To avoid installation difficulties, do not run the door operator until instructed to do so. • Loosen the collar screws. • Attach collar to either the left or the right side of the operator. Ensure that the collar is seated all the way on motor shaft until stop is reached (Figure 1).
WARNING INSTALLATION IMPORTANT INSTALLATION INSTRUCTIONS WARNING 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 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.
INSTALLATION STEP 2 Attach the Emergency Release Rope and Handle To prevent possible SERIOUS INJURY or DEATH from a falling door: • If possible, use emergency release handle to disengage door ONLY when door is CLOSED. Weak or broken springs or unbalanced door could result in an open door falling rapidly and/or unexpectedly. • NEVER use emergency release handle unless doorway is clear of persons and obstructions.
INSTALLATION STEP 4 Figure 1 Attach the Cable Tension Monitor (Required) Operator This operator comes standard with the cable tension monitor. It is supplied as a device to monitor the cables for ANY slack that may occur and will reverse the door when excessive slack is detected, eliminating service calls. The cable tension monitor MUST be connected and properly installed before the door operator will move in the down direction. NOTE: The cable tension monitor is shipped for left side installation.
INSTALLATION STEP 5 Install the Single Button Control Station To prevent possible SERIOUS INJURY or DEATH from electrocution: • Be sure power is not connected BEFORE installing door control. • Connect ONLY to 24 VOLT low voltage wires. To prevent possible SERIOUS INJURY or DEATH from a closing door: • Install door control within sight of door, out of reach of children at a minimum height of 5 feet (1.5 m) and away from ALL moving parts of door.
IMPORTANT SAFETY INSTRUCTIONS WARNING To reduce the risk of SEVERE INJURY or DEATH: 1. This portable luminaire has a polarized plug (one blade is wider than the other) as a feature to reduce the risk of electric shock. 2. This plug will fit in a polarized outlet ONLY one way. 3. If the plug does not fit fully in the outlet, reverse the plug. 4. If it still does not fit, contact a qualified electrician. 5. NEVER use with an extension cord unless plug can be fully inserted. 6. Do not alter the plug. 7.
INSTALLATION STEP 7 Electrical Requirements To prevent possible SERIOUS INJURY or DEATH from electrocution or fire: • Be sure power is not connected to the operator, and disconnect power to circuit BEFORE removing cover to establish permanent wiring connection. • Door installation and wiring MUST be in compliance with ALL local electrical and building codes. • NEVER use an extension cord, 2-wire adapter or change plug in any way to make it fit outlet. Be sure the operator is grounded.
INSTALLATION STEP 8 Mount the Standby Power Unit (SPU) (Not Provided) 475LM Standby Power System If the optional 475LM Standby Power Unit is part of this installation it should be installed at this time. • The SPU can be mounted to either the ceiling or a wall within 3' (.9 m) of the motor unit. • Position the SPU as desired to a structural support (ceiling joist or wall stud). • Attach the SPU to the support using the mounting holes on either side of the SPU.
INSTALLATION STEP 7 Install The Protector System® Be sure power is not connected to the door operator BEFORE installing the safety reversing sensor. To prevent SERIOUS INJURY or DEATH from a closing door: • Correctly connect and align the safety reversing sensor. This required safety device MUST NOT be disabled. • Install the safety reversing sensor so beam is NO HIGHER than 6" (15 cm) above floor.
INSTALLING THE BRACKETS Be sure power to the operator is disconnected. Install and align the brackets so the safety reversing sensors will face each other across the door, with the beam no higher than 6" (15 cm) above the floor. They may be installed in one of three ways, as follows. Figure 1 DOOR TRACK MOUNT (RIGHT SIDE) Door Track Lip Indicator Light Door track installation (preferred) (Figure 1): • Slip the curved arms over the rounded edge of each door track, with the curved arms facing the door.
MOUNTING AND WIRING THE SAFETY REVERSING SENSORS • Slide a 1/4"-20x1/2" carriage bolt head into the slot on each sensor. Use wing nuts to fasten safety reversing sensors to brackets, with lenses pointing toward each other across the door. Be sure the lens is not obstructed by a bracket extension (Figure 5). • Finger tighten the wing nuts. • Run the wires from both safety reversing sensors to the operator. Use insulated staples to secure wire to wall and ceiling.
ADJUSTMENT STEP 1 Program the Travel Limits Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing door. • NEVER learn forces or limits when door is binding or sticking. Repair door first. • Incorrect adjustment of door travel limits will interfere with proper operation of safety reversal system. • After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.
ADJUSTMENT STEP 2 Setting the Force Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing door. • NEVER learn forces or limits when door is binding or sticking. Repair door first • Too much force on door will interfere with proper operation of safety reversal system. • After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.
ADJUSTMENT STEP 3 Test the Safety Reversal System Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing door. • Safety reversal system MUST be tested every month. • If one control (force or travel limits) is adjusted, the other control may also need adjustment. • After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" (3.
ADJUSTMENT STEP 5 Test Cable Tension Monitor To prevent possible SERIOUS INJURY or DEATH from a falling door: • If possible, use emergency release handle to disengage door ONLY when door is CLOSED.
