Insinkerator AS-2 Service Manual

AQUA SAVER™ SYSTEM
INSTALLATION PROCEDURE

THE AQUA SAVER disposer water saving

system consists of one:

• Aqua Saver Module

• 1 gallon per minute (GPM) flow control valve

• Solenoid valve
The Aqua Saver System is designed to be

used in conjunction with a new commercial
disposer installation, or an existing
installation. In either case, a second solenoid
valve is

required for the Aqua Saver to work properly.
If you are installing a new disposer, the

second solenoid is a standard item with all
In-Sink-Erator commercial disposer
packages.

If you are installing the Aqua Saver to an
existing disposer, the second solenoid will
already be in place. If for some reason there
is no second solenoid valve, one must be
purchased.

Operation

The Aqua Saver System senses the load on the disposer motor, and regulates the amount of
water necessary for grind and no grind load situations.

When the disposer is turned on and not grinding food waste the water flow to the disposer
should be at a slow flow rate - 1 gallon per minute (GPM).

When the disposer is grinding food waste the increased load is detected and the water flow rate
increases to insure that the food waste is flushed through the drain lines.

When the disposer is finished grinding the water flow decreases back to the slower rate of 1
GPM.

Important

These installation instructions are for the benefit of the installing contractor. The In-Sink-Erator
Company or any of its Authorized Service Agencies do not make original installations. For
technical information not covered in the foregoing instructions contact the supplier, In-Sink­Erator Area Field Sales Representative or the Factory.

These electrical and plumbing instructions are written for competent and experienced installers.
If the installer is not experienced in these areas, we recommend that assistance from a
competent professional be sought. Improper installations resulting in damage to the disposer or
accessories are not covered by the manufacturer's warranty.

Make all installations in accordance with local plumbing and electrical codes.

CONNECTIONS

Recommended Installation of Aqua Saver System

Plumbing

Plumb the two water solenoid valves in parallel with each other and feed outlet to sink bowl or
disposer water inlet.

Important (See drawing below)

• The 1 GPM flow control (included with Aqua Saver) always plumbs to the solenoid valve supplied with the disposer
package, or the solenoid valve on an existing disposer installation.

• The X GPM flow control will be supplied as a standard item with a new In-Sink-Erator disposer package, or will be
in-line in an existing disposer installation. The Aqua Saver will work without the X GPM flow control, but it is
recommended as part of the installation. The X GPM flow control must always be plumbed to the 120/230 volt
solenoid valve supplied with the Aqua Saver package.

CONNECTING THE SOLENOID VALVES

General solenoid connection

Aqua Saver modules

The two solenoid valves are connected
to the Aqua Saver module by three
wires.

Note: When the disposer is initially
turned on, both solenoid valves will
operate. After approximately 15 sec­onds, the water flow to the disposer
will slow to 1 GPM, if you are not
grinding food waste.

• GPM varies by model
