Introduction/Features

INTRODUCTION

The AS-101K Control Center is CUL® US listed for use with InSinkErator Foodservice Disposers. See Table 1 for electrical specifications. The control center operates the disposer and control center combinations. 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. Two solenoid valves are used to control high and low water flows.
• To allow water flow for several minutes to flush the drain line after the disposer is turned off.

Table 1. Electrical Specifications

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 ground food waste is flushed out of the drain line. Adjust water shutoff delay as described in the operating instructions on page 7.

AUTOMATIC WATER REGULATION

This acts as an on-demand water saving system for InSinkErator Foodservice Disposers. It senses the load of the disposer, and regulates the amount of water necessary for grinding and non-grinding situations. This 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 gallon per minute if there is not 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 manual 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 Dip Switch Module at the top of the printed circuit board (see Figure 8). Move the

5 dip switch from MANUAL to AUTOMATIC. The disposer now automatically shuts

off 10 minutes after it starts.

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.

LOW VOLTAGE CONTROL

Controls operate on a 24 V solid state control circuit.

ENCLOSURE

NEMA 4 construction. PUSH BUTTON OPERATION Push Black button to start disposer. Push Red button to stop disposer.

PROPERTY DAMAGE

Use of more than two solenoid valves will affect the overall function of the Aqua Saver® systems. Extra solenoid valves will cause a reduction in voltage and solenoid actuation will not occur.

Mounting the Control Center/Plumbing Connections

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

Locate control center within sight o  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 with flow control valves pre-installed (1 GPM and 7 GPM) are packed with the control center. The syphon breaker is 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 the water flow direction arrows marked on the valve 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 plane per local plumbing codes. Check direction of water flow arrows.

NOTE : The AS-101K control center requires the use of two solenoid valves and two flow control valves.

CURRENT SENSING CONTROL SET-UP

See Figure 9.

1. Adjust the trip delay to mid-setting. This adjusts
   the length of the time the water runs at full flow
   after grinding is completed. Mid-setting is
   approximately 45 seconds.

2. With the disposer running at high water flow:
   a. Adjust the trip point control to maximum position, the light is not illuminated.
   b. Turn the trip point control counterclockwise until the red fault light is illuminated, stop.
   c. Turn the trip point control clockwise slowly, stopping immediately when the red fault light is no longer illuminated. Turn slightly counterclockwise incrementally with the light remaining off to assure you are at the exact set point. To ensure sensitivity, the trip point must be set at the exact point the light becomes no longer illuminated.

NOTE: Water flow will decrease after trip delay time setting expires.
