FEATURES
INTRODUCTION
The AS-101 K Control Center is UL listed for use with ISE
Commercial Food Waste Disposers. See Table 1 for approved
disposer and control center combinations. The control center
operates the commercial disposer. Its main functions are:
• To start and stop the disposer.
• To reverse the direction of the disposer motor automatically upon
restart.
• To start the water flow to the disposer.
• To regulate the amount of water needed for operation.
• To allow water flow for several minutes to flush the drain line after
the disposer is turned off.

AUTOMATIC WATER REGULATION
This acts as an on-demand water saving system for ISE
Commercial Food Waste Disposers. It senses the load of the
disposer, and regulates the amount of water necessary for
grinding and non-grinding situations. (Uses two solenoid valves.)
NOTE: When the disposer is first turned on, both solenoids will
operate. After the set time has expired, the flow to the disposer
will slow to one (1} gallon per minute if there is no food waste
present in the grinding chamber.
AUTOMATIC TIMED DISPOSER SHUTOFF
This water saving feature allows the disposer to run for up to 10
minutes before it automatically shuts off and must be manually
restarted.
NOTE: This feature is set in the off position at the factory. To
activate the automatic timed disposer shutoff, disconnect the
electric power to the control center, then open the control center
door. Locate the shutoff plug at the top of the circuit board (See
page 6, Figure 7). Move the plug from manual (MAN) pins to
automatic (AUTO) pins. The disposer now automatically shuts off
10 minutes after it starts.
EXTERNAL REMOTE CONTROL
One or more remote controls may be connected to the control
center. These enable the operator to start or stop the disposer
from any control station. A 24 V control circuit provides low
voltage push button operation.
ELECTRIC DISCONNECT SWITCH
The lever switch on the front panel of the control center
disconnects line voltage. It interlocks with the front cover so that
the cover cannot be opened unless the switch is in off position.
LOW VOLTAGE CONTROL
Controls operate on a 24 V solid state control circuit.

FEATURES
AUTOMATIC REVERSE
The disposer motor will reverse its direction of rotation automatically upon restart. To avoid motor damage, a five second delay
feature prevents reversing while the motor is coasting.
WATER SHUTOFF DELAY (POST FLUSH)
After the motor is turned off, the water continues to flow for up to 10
minutes. The length of this post flush is controlled by the water
shutoff delay timer. The post flush helps ensure that und food
waste is flushed out of the drain line. Adjust water delay as
described in the operating instructions on page 6.
ENCLOSURE
Stainless steel NEMA 4 construction.
PUSH BUTTON OPERATION
Push black button to start disposer. Push
red button to stop disposer.

MOUNTING THE CONTROL CENTER/PLUMBING CONNECTTIONS
MOUNTING THE CONTROL CENTER
Use 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.
Locate any remote control station 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
Two solenoid valves and one (1) GPM flow control valve are
packed with the control center. The (X) GPM flow control valve and
syphon breaker are supplied with all complete disposer packages
(packed separately).
The solenoid valve is supplied with a 24 V coil. 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.
A syphon breaker must be installed above the sink flood plane per
local plumbing codes. Check direction of water flow arrows.
FIGURE 1. Control center dimensions
NOTE: The AS-101 K control center requires the use of two (2)
solenoid valves and (2) flow control valves. Figure 2 shows the
recommended installation for an AS101K control center.
