FEATURES
SINGLE BUTTON OPERATION
Disposer and Waste Xpress are controlled by simple
ON/OFF button operation.
AUTOMATIC REVERSE
The disposer motor will reverse its direction of
rotation automatically upon restart. To avoid motor
damage, a delay feature prevents reversing until
the post fl ush is complete.
WATER SHUTOFF DELAY (POST FLUSH)
After the motor is turned off, the water continues to
fl ow for up to 10 minutes. The length of this post fl ush
is controlled by the water shutoff delay timer. The post
fl ush helps ensure that ground food waste is fl ushed
out of the drain line.
AUTOMATIC TIMED DISPOSER SHUTOFF
This water saving feature allows the system to run for
10 minutes before it automatically shuts off and must
be manually restarted.
LINE DISCONNECT SWITCH
The switch on the front panel of the control center
disconnects the line voltage. It interlocks with the front
cover so that the cover cannot be opened unless the
switch is in the off position.
LOW VOLTAGE CONTROL
Control operates on a 24 V solid state control circuit.
ENCLOSURE
Stainless steel NEMA 4 construction.
WX TIMER HOT WATER SPRAY ADJUSTABLE
Factory set for 2 minutes off 10 second on controls hot
water spray for cleaning of screen.

disposer. Check nameplate for specifi cation.
• Electrical connections should be made by a
qualifi ed electrician and should comply with all
local codes.
• Turn off electrical supply to Waste Xpress,
control center & disposer before attempting to
work on it. Test with a volt meter or circuit tester
