Before starting the installation of the operator, the door must be in
good working condition and properly counterbalanced. Inspect
the door and track for loose or missing hardware. Test the door
manually for balance and ease of operation. Lubricate door hinges
and rollers. If necessary, employ a qualified technician to adjust
the springs for proper counterbalance of the door.
Stops should be installed at the top end of each track to prevent
the possibility of the door rollers moving beyond the ends of the
track.
If the cross header shaft is made from hollow tubing rather than
solid rod, it is recommended that it be plugged with a short length
of solid bar for a more secure installation of the shaft sprocket or
flange coupler.
Before removing the operator powerhead from the shipping
carton, inspect the nameplate on the cover of the operator
control box to verify that it is the correct model for the
intended application and that the voltage and phase are in
accordance with electrical power provided at the job site. If
the operator was ordered with the optional chain hoist,
Model MH5011S, see that it is so equipped. A chain hoist
CANNOT be added in the field.
Warning: Rope off the area to keep personnel and
vehicles clear of the door and floor space in the vicinity
of the operator during the installation.
