WARRANTY

FOODSERVICE DISPOSER CONTROL CENTER

LIMITED WARRANTY

InSinkErator Foodservice Disposer Control Centers are
warranted against defects in material and workmanship
for one year from the date of installa tion. The warranty
includes parts and labor, pro vided the service is performed
by an InSinkErator 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. InSinkErator Foodservice disposer
accessories are included in this warranty only if they
are included in the original disposer purchase package.

INTRODUCTION

INTRODUCTION

The MSLV Control Center is CUL® US listed for use
with InSinkErator Commercial Food Waste Disposers.
See Table 1 for approved combinations and Table 2 for
electrical specifications. The control center operates the
disposer. Its main functions are:

• To start and stop the disposer.

• To start the water flow to the disposer.

LOW VOLTAGE CONTROL
Controls operate on a 24 V solid state control circuit.

ENCLOSURE
Stainless steel NEMA 4 construction.

ELECTRIC DISCONNECT SWITCH
The lever 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.

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
enclosure 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

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.

ELECTRICAL CONNECTIONS

ELECTRIC SHOCK

• 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.

PROPERTY DAMAGE

• 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.

All pipe fittings are ½” NPT (National Pipe Taper)

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). All control
centers and disposers must be carefully and permanent ly
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.
Con nect solenoid valve to the low-voltage solenoid
terminals numbers 4 and 5.

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
pres ent at the disconnect until power is turned off at the
supply source.
