PROPERTY DAMAGE
System has hot water spray that must be
connected. Fresh water connection to the
Waste Xpress must be hot water only. Failure
to use hot water may clog system and result
in malfunction.
WASTE OUTLET LINE
Connect a 2" drain line to the Waste Xpress waste
outlet as specifi ed per local codes (see Figure 18
for water outlet location).
InSinkErator recommends that the water outlet
empties into a fl oor drain.
If the water outlet connection on the Waste Xpress
needs to be switched to the other side, complete
the following:
• Remove the four screws holding the cap and gasket in
position (see Figure 18).
• Install gasket, cap and inlet fi tting on reverse side
and secure with appropriate screws.
NOTE: The Waste Xpress system should not be
plumbed directly into a small inside grease trap.
The unit can be plumbed through a large exterior
grease trap.
WATER SUPPLY CONNECTIONS
When connecting the incoming water supply to the
disposer, sink bowl and Waste Xpress, use as few
elbows and tees as possible.
All cold water line fi ttings are 1/2" NPT except the
sink bowl nozzles which are 1/2" compression.
Use 1/2" compression fi tting to connect hot water
to Waste Xpress.
Install the fl ow control valve, water solenoid valve,
and syphon breaker according to the direction of the
arrows marked on each valve body.
NOTE: In-line hot and cold shutoff valves are
recommended close to the Waste Xpress system
for ease of service.
ROUTING WATER FLOW
Connect cold water only to disposer, bowl, or trough.
Connect hot water only to Waste Xpress for hot water
spray nozzles.
In a trough system, route all water fl ow to the end of
the trough to fl ush food waste.

PLUMBING CONNECTIONS
The syphon breaker is supplied with all Waste Xpress
systems (packed separately).
Syphon breaker must be installed above the sink fl ood
plane per local plumbing codes. Check direction of
water fl ow arrows.
The solenoid valve is supplied with a 24 V coil.
• The fl ow control valve regulates all cold water fl owing
into the disposer and Waste Xpress. This conserves
water and prevents overloading.
