• Ensure that Waste Xpress voltage and phase match
that of the electrical supply, control center &
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
to ensure that power is off.
• Do not operate unit with panels removed.
• All components (disposer, WX, control center
and solenoids) must be carefully and permanently
grounded.
• A properly fused disconnect must be installed at
Waste Xpress, control center & disposer electrical
supply source.
• Use only NEMA 4 watertight electrical connectors
when connecting to junction box.
WASTE XPRESS LOCATION
NOTE: Prior to installing the Waste Xpress the
disposer and control center should be installed as
specifi ed within this manual.
• Position Waste Xpress within 10 feet of the disposer
outlet fl ange. A maximum of four (4) 90º elbows can
be used between the disposer and Waste Xpress
(prefer 45º elbow).
