Planning

Survey the area to see if any of the conditions below apply
to your installation. Additional materials may be required.
You may find it helpful to refer back to this page as you
proceed with the installation of your operator.
Depending on your requirements, there are several
installation steps which may call for materials or hardware
not included in the carton.
This operator is compatible with:
• Doors that use a torsion bar, springs and a door no
more than 3.8m (12.5ʼ) high.
• 100mm - 150mm drums (4" to 6") , NOT TO BE USED
on tapered drums over 150mm (6").
• High lift and standard lift sectional doors up to 3.8m
(12.5ʼ) high.
• Doors up to 5.5m (18ʼ) wide.
• Doors up to 16m (170 sq ft)
2
• 25mm (1") torsion bar only.

Reversing Sensor
• The torsion bar must extend at least 25mm to 100mm
(1" to 4") past the bearing plate.
• An electric outlet is required within 1.8m (6ʼ) of the
installation area. If outlet does not exist, contact a
qualified electrician.
• Depending upon buildingʼs construction, extension
brackets or wood blocks may be needed to install safety
reversing sensors.
• A model CM475 EverCharge
(SPU) is strongly recommended if there is no access
door to the building, as this operator cannot be used in
conjunction with an external emergency release
mechanism.
• Any gap between the floor and the bottom of the door
must not exceed 6mm (1/4"). Otherwise the safety
reversal system may not work properly.
NOTE: Inspect the torsion bar while the door is raised and
lowered. It is important that there is no noticeable
movement up and down or left and right. If this type of
movement is not corrected, life of this operator will be
greatly reduced.
