Sink Chemical Dispensing System
Installation and Setup Guide
SuperSink accurately blends proportioned chemical with water for cleaning, sanitizing or other related
needs in a commercial kitchen. The dispensing system uses a pilot drive water valve designed for
easy maintenance. SuperSink is engineered with 1055 approved back flow protect using DEMA’s Air
Gap or Action Gap proportioning system.
Warnings
All installations must conform to local plumbing codes and use approved backflow prevention devices.
A pressure indicating tee is to be installed with existing faucets according to local plumbing codes in the
state of Wisconsin and any other state that requires the use of a pressure indicating tee.
ALWAYS WEAR PROTECTIVE CLOTHING AND EYEWEAR WHEN WORKING WITH CHEMICAL
PRODUCTS.

4. Locate the key shaped mounting holes in the back plate. Mount the SuperSink using the mounting
screws and anchors that are included in the installation kit.
5. Install the desired metering tip by threading tip into the proportioner chemical pick-up elbow.
6. Cut the chemical supply tube to the length allows the foot valve to rest on the bottom of the chemical
container. Slide the ceramic weight onto the chemical supply tube until it is against the foot valve. This
will keep the foot valve at the bottom of the chemical container.
a. Note: Chemical containers cannot be greater than 6 feet (1.8M) below the SuperSink dispenser.
7. Cut the outlet tubing to the desired length. When using the system to fill sinks, it is recommended to cut
the out let tubing so that it is above the intended fill line (water line).
8. Install the SuperSink cover by positioning the tab at the bottom of the cover near the dispenser
discharge and push the cover back over the valve assembly until the tabs latch on both sides of the
unit.
9. Connect the water line to the inlet of the SuperSink.
a. Note: The water pressure must be between 20psi and 95psi. Optimum chemical induction occurs
between 30psi – 60psi.
b. The water inlet options for the SuperSink are:
i. Garden Hose (female)
ii. 3/8” Elbow Brass Compression Fitting (suitable for 3/8” OD soft copper water line)
iii. 3/8” Straight Brass Compression Fitting (suitable for 3/8” OD soft copper water line)
iv. 3/8” John Guest Push-on Water Fitting (suitable for 3/8” OD soft copper or LDPE tubing)
v. 3/8” Elbow John Guest Push-on Water Fitting (suitable for 3/8” OD soft copper or LDPE
tubing)
vi. 3/8” Brass Barb Water Fitting (suitable for 3/8” LDPE tubing)
b. Faucet adapter kits are often used to provide
water source to the dispenser. DEMA
recommend P/N 68.4 NSF which includes
faucet adapters for T&S, Chicago and Fisher
faucets.
