FOODSERVICE DISPOSER CONTROL CENTER
LIMITED WARRANTY
In-Sink-Erator Foodservice Disposer Control Centers are warranted against defects in material and
workmanship for one year from the date of installation. The warranty includes parts and labor, provided the service is performed by an In-Sink-Erator
Factory Authorized Service Center. This warranty
does not apply if failure is due to: faulty or improper
electrical installation, faulty or improper plumbing
installation, product abuse or misuse, or accidental
damage.
INTRODUCTION
The MSLV Control Center is UL
In-Sink-Erator Commercial Food Waste Disposers.
See Table 1 for approved combinations. The control
center operates the disposer. Its main functions are:
• To start and stop the disposer.
• To start the water flow to the disposer.

ENCLOSURE
Stainless steel NEMA 4 construction.
ELECTRIC DISCONNECT SWITCH
3
The lever switch on the front panel of the control center
disconnects the line voltage. It interlocks with the front
4
cover so that the cover cannot be opened unless the
4
switch is in the off position.

NOTE:
Use of the electrical disconnect switch results
in a 30-second delay before system can be restarted.
You must wait 30 seconds after reactivation of the line
disconnect switch before system will start.
PUSH BUTTON OPERATION
Push Black button to start disposer.
Push Red button to stop disposer.
Mounting the Control Center
MOUNTING THE CONTROL CENTER
Use the flanges at the back of the control center enclo
sure and only mount panel in the upright vertical position
(door hinge is on the left - see Figure 1).
Locate control center within sight of disposer per local
codes.
If box is mounted to the sink table, recess the box so that
the buttons do not extend beyond the table’s edge.

PLUMBING CONNECTIONS
The solenoid valve is packed with the control center. The
flow control valve and syphon breaker are supplied with
all complete disposer packages (packaged separately).
The solenoid valve is supplied with a 24 V coil. Make cer
tain that the valves are plumbed according to the water
flow direction arrows marked on the valves, or the valves
will not function properly.
The flow control valve regulates all water flowing into the
disposer. This conserves water and prevents overload
ing. Check direction of water flow arrows.
A syphon breaker must be installed above the sink flood
plane per local plumbing codes. Check direction of water
flow arrows.
• Turn off the electrical supply to the disposer before
attempting any work on it. Use a voltmeter or
circuit tester to ensure that the power is off.
• All installation work must conform to local
plumbing and electrical codes.
• All control centers and disposers must be
carefully and permanently grounded.
• A properly fused disconnect must be installed at
the electrical supply source for the control center.
• Ensure that control center voltage and phase
match the disposer motor and electrical supply.
Check name plates on disposer and control
centers for voltage and phase specifications.
• Refer to the control center wiring diagrams in this
manual for correct connection.
• Use NEMA 4 watertight electrical connectors (not
supplied) when making electrical connections to
the control center.
NOTE: The MSLV control center has a door disconnect
switch, the disconnect switch must be in the off position
before the panel door can be opened. Power is still present at the disconnect until power is turned off at the supply
source.

Electrical Connections
ELECTRICAL CONNECTIONS
The MSLV control center uses low-voltage (24 V) to oper
ate contactor coils, push buttons and solenoid valves. Red
wires denote the 24 V circuit.
Connect the incoming line power to the electrical door dis
connect switch and connect the disposer motor to labeled
terminal blocks in the control center. Use the appropriate
schematic wiring diagram, Figures 5, 6, 7 or 8. Wiring
diagram is also located on the inside door of the control
center. Wire the disposer motor for correct voltage using the
connection diagram inside the motor terminal box.
Wire per local electrical code using 7/8" diameter holes in
the bottom of the control center cabinet, and install NEMA 4
watertight electrical connectors (not supplied).
centers and disposers must be carefully and permanently grounded.
After completing the connections, close door and fasten
all locking clamps. Replace disposer motor cover. Turn on
power.
WATER SOLENOID VALVE
Connect water solenoid valve as shown in Figure 3.
