The Crown 1502 Electric Door Operator has been
designed primarily for commercial and industrial
installations where the operator has to withstand
constant hard use. To ensure correct installation
and proper operation of the operator and associated
hardware, the following instructions are given:
(1) SHIPMENT CHECK: Included with the installation
packet is a copy of the packing slip for the components
supplied with the order. Compare the components
received with the packing slip to insure that all
equipment is complete.
(2) REVIEW INSTALLATION DRAWINGS: The
installation drawings show the layout of the door,
template drilling for the door and jamb, and general
terms used to describe the components. Review the
drawings to familiarize yourself with the equipment.
(3) CHECK THE DOORS: Prior to installing the
operator, confirm the doors are properly hung. 95% of
all door operator trouble is caused by doors not swinging
free of the floor and lintel. It is also very important that
all hinge pins are properly aligned and there is no hinge
binding.
