Features/Mounting the Control Center
INTRODUCTION
MOUNTING THE CONTROL CENTER
®
®
The MS Control Center is UL and CUL approved for
use with InSinkErator Foodservice Disposers. See
Table 1 for approved disposer and control center
combinations. The control center operates the disposer.
Its main functions are:
Use the flanges at the back of the control center
enclosure and only mount panel in the upright vertical
position. See Figure 1.
Locate control center within sight of disposer per local
codes. Locate any remote control station within sight of
disposer per local codes.
• To start and stop the disposer.
• To start the water flow to the disposer.
If box is mounted to the sink table, recess the box so
that the buttons do not extend beyond the table's edge.

Table 2. Electrical Specifications
Use of more than two solenoid valves will affect
the overall function of the MS control center. Extra
solenoid valves will cause a reduction in voltage and
solenoid actuation will not occur.

Plumbing Connections
Figure 2. Typical Installation Diagram
PLUMBING CONNECTIONS
The flow control valve, syphon breaker and solenoid
valve are supplied with all complete disposer packages
(packed separately).
Make certain that the solenoid valve supplied is
the proper voltage. Make certain that the valves
are plumbed according to water flow direction
arrows marked on valves or the valves will not
function properly.
The flow control valve regulates all water flowing into
the disposer. This conserves water and prevents
overloading. Check direction of water flow arrows.
Syphon breaker must be installed above the sink flood
place per local plumbing codes. Check direction of
water flow arrows.

Electrical Connections
ELECTRIC SHOCK
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.
• Turn off the electrical supply to the disposer before
attempting any work on it. Use a voltmeter or
circuit tester to ensure that power is off.
• All installation work must conform to local
plumbing and electrical codes.
• Refer to the control center wiring diagrams in this
manual for correct connection.
• All control centers and disposers must be carefully
and permanently grounded.
• Use NEMA 4 watertight electrical connectors
(not supplied) when making electrical connections
to the control center.
• A properly fused disconnect must be installed at
the electrical supply source for the control center.
ELECTRICAL CONNECTIONS
4
Connect the incoming line power and disposer motor
to the labeled terminal block in the control center. Use
appropriate voltage and phase electrical connection
diagrams at the back of this manual. Wire the disposer
motor for the correct voltage using the connection
diagram inside the motor terminal box.
6
Make sure the solenoid valve is the same voltage as the
control panel and supply power.
3
Connect water solenoid valve as shown in the wiring
diagrams on pages 7, 8, 9, and 10.

Time Adjustment Knob
Wire per local electrical code using 7/8" diameter holes
in bottom of control center cabinet and install NEMA 4
watertight electrical connectors (not supplied).
Figure 3. 120V or 208/230V Time Delay Relay
After completing the connections, secure cover.
Replace disposer motor cover.
TIME DELAY RELAY
(Optional, not supplied with MS)
The time delay relay may be used with the MS to
delay solenoid valve shut-off, providing a post flush.
This helps prevents drain line stoppages and is
beneficial when ground food waste must travel through
many bends or a long horizontal run. It is adjustable
from 0 to 10 minutes and factory set to provide
approximately a 5 minute delay. To adjust, SHUT OFF
ELECTRIC POWER. Inside unit, locate the adjustment
potentiometer. Turn clockwise to increase delay. Turn
counterclockwise to decrease delay. See Figures 4 and
5 for wiring.
Figure 4. Time Delay Relay Connections - 120V or 208/230 V
Ensure the voltage rating on the time delay relay and
solenoid valve are the same as the disposer motor
and line voltage.

Operating Instructions/Troubleshooting
PERSONAL INJURY
ELECTRICAL SHOCK/PROPERTY DAMAGE
• Troubleshooting other than what is recommended
in this section should only be performed by
qualified service personnel.
• Allow only trained personnel to operate disposer.
• Use baffles and guarding to avoid splashing and
ejection of materials.
• Further troubleshooting performed by untrained
personnel could result in electric shock or damage
to the control center.
• Do not put fingers or hands into the disposer.
• When attempting to remove objects from a
disposer, use long-handled tongs or pliers.
• All electrical checks must be performed by a
qualified professional.
• Turn power off before clearing a jam, removing
an object from the disposer or pressing the red
reset button.
TROUBLESHOOTING
This control center was inspected and tested under
operating conditions before shipment from the factory.
In case of trouble, check the items listed below.
OPERATING INSTRUCTIONS
TO START
1. Check to ensure disposer is free of foreign objects.
A. Disposer motor will not start and water
does not flow.
2. Ensure power is on.
3. Push start button. Disposer motor will run and water
will flow into the disposer.
1. No incoming line power, turn line power on.
B. Disposer motor stops while grinding but water
continues to flow.
TO STOP
1. Push stop button. Disposer motor and water will stop.
1. Disposer is jammed. Press the stop button and
follow directions for unjamming that were
supplied with the disposer.
2. Disposer motor overload protector has tripped.
Follow instruction in C1.
C. Disposer will not start but water flows.
1. Overload protector on the disposer may have
tripped. Press stop button. Locate red reset
button on front of disposer electrical cover. Press
to reset. If motor had been running, wait five
minutes for the motor and overload to cool down
before starting.
2. Disposer is jammed. Press the stop button and
follow directions for unjamming that were
supplied with the disposer.
D. Water flows constantly before start button
is pushed.
1. Water solenoid valve is installed backward.
Water flow should be in the direction of the
arrow on valve.
2. Water solenoid valve is wired incorrectly.
Recheck wiring diagram.
E. Overload trips frequently.
1. Do not overload disposer with excess amounts of
garbage and water. (See disposer instructions for
recommended water flows.)
If trouble still persists, call your nearest InSinkErator
Authorized Service Agency. For the location of your
nearest service agency, call toll-free 1-800-845-8345.
