Knight Equipment SINK BOWL Installation Manual

INSTRUCTION MANUAL

WARNING: DUE TO THE TYPICAL INSTALLATION REQUIREMENTS AND THE CAUSTIC CONTENT OF MANY
CHEMICAL PRODUCTS, IT IS REQUIRED THAT ALL WATER SUPPLIES BE SHUT OFF BEFORE CONNECTING
OR SERVICING THE SINK BOWL.

INSTALLATION / OPERATION

See the diagram on the following page for reference to the installation and calibrating steps below.

(1) Mount the Sink Bowl to the wall, use the wall anchors and screws provided with the accessory kit.
(2) Run flow tubing from the output fitting on the bottom end of the bowl body into the sink. The first 12" of the

tubing run should be vertical to prevent liquids from backing up into the bowl.

(3) Connect 3/8" OD tubing from the water source to the input fitting of the Sink Bowl and tighten carefully. The

compression fitting can be removed for direct hard-plumbing with a 3/8" NPT connection, or can be substituted
by a barb fitting or garden hose adapter.

IMPORTANT NOTES:
140°F. Use of 1/4” water supply line is not recommended.

(4) Insert a detergent container into the Sink Bowl, ensuring the container presses down the paddle valve lever. The

paddle valve is a safety feature that will shut off water spray into the bowl if the container is removed.

(5) Rotate the water valve T-handle counter-clockwise (vertical) to turn on water flow. Water will spray up inside the

container (to dissolve detergent) and will also flow into the j unction fitting at the bowl bottom where it will mix
with the dissolved detergent that exits the bowl. Turn the T-handle clockwise (horizontal) to shut off.

Incoming water pressure must be 25 - 80 PSI. Do not use water temperature higher than

CALIBRATING DETERGENT CONCENTRATION

The c oncentration of dissolved detergent is adjusted by regulating flow to the spray jet with the needle valve. A
special tool is provided for adjusting the needle valve — the tool is a 3” long brass tube with one end slotted for
gripping the T-handle of the needle valve. Removing the metal cover from the Sink Bowl is not required.

(6) Insert the slotted end of the tool through the access hole on the right side of the metal cover and close the

needle valve by turning clockwise until it stops. Then turn counter-clockwise 3 full turns to adjust the needle
valve to its mid-point (6 full turns is maximum). Turn the water valve “on” to verify detergent is dissolving.

(7) Check the solution strength of the water/detergent mixture dispensed by the Sink Bowl. Adjust the needle valve

as needed to achieve the desired mix (clockwise for less detergent, counter-clockwise for more detergent).
