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.

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.

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.

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.
