0900456 Rev: G (ECO 6537) Page 1 of 4
INTRODUCTION
The Knight Sani-Clean III is the perfect dispensing system for supermarket meat rooms, kitchen areas, bakeries,
seafood stores, auto dealers, truck washing, loading docks, etc. The Knight Sani-Clean III is the economical system
for controlling cleaning costs. Chemicals are mixed accurately and consistently at your chosen dilution ratio, utilizing
two in-line venturi valves. Up to 16 different product concentrations are available using “screw-in” metering tips.
INSTALLATION
(1) Mount the unit to the wall using the screws and anchors provided.
(2) Mount the hose bracket to the wall using the screws and anchors provided.
(3) Select the appropriate metering tip (see chart on the following page) and screw into
end of barb fittings. The cover does not need to be removed to access the barb
fittings.
(4) Install foot strainer on the end of each supply tube. Slide a ceramic weight over
each supply tube, then connect the tube onto the barbed fittings. Cinch a plastic tie
wrap (provided) around the connection to secure. Insert foot end into container.
(5) Connect to a water supply using the provided 3/4" garden hose adapter on the left
side of the unit — the adapter can be removed to permit hard plumbing directly to
3/8" or 1/2" NPT water line. Water pressure should be 30 to 80 PSI. Water
temperature should not exceed 140 degrees (F).
(6) Attach the nozzle to the end of the output hose, then connect the hose to the fitting on the bottom of the
unit.
OPERATION
(1) Turn on desired supply valve, Detergent, Rinse, or Sanitizer, and depress spray nozzle handle. The selected
product and water mixture will be dispensed.
(2) To use the Foam feature, attach the Foam Wand to the quick-connect coupling on the end of the nozzle (be sure
air intake holes are not obstructed) and depress spray nozzle handle.
IMPORTANT NOTES
 ONLY USE A HOSE AND SPRAY NOZZLE SUPPLIED BY KNIGHT LLC.
 DO NOT ADJUST THE KNOB ON THE SPRAY NOZZLE FROM THE FULL SPRAY POSITION.
 DO NOT OPERATE MORE THAN ONE PRODUCT VALVE AT A TIME, AS PRODUCT DILUTION RATES WILL
NOT BE ACCURATE.
 UNIT SUPPLIED WITHOUT A BACKFLOW PREVENTION DEVICE. TO PREVENT POSSIBLE CHEMICAL
BACKUP INTO THE WATER SUPPLY, COMPLY WITH ALL LOCAL PLUMBING CODES AND INSTALL AN
APPROPRIATE BACKFLOW PREVENTION DEVICE.

METERING TIP RATIOS
PROBLEM POSSIBLE CAUSE REMEDY
No output (1) Water supply is off
(2) Product valve is off (1) Turn water supply on (2) Turn appropriate valve on
Product is not drawn from container (1) Footvalve obstruction
(2) Clogged metering tip
(3) Water inlet blocked
(4) Low water pressure
(5) No product in container
(6) Supply tube is loose
(7) Hose nozzle not fully open
(1) Clean or replace
(2) Clean or replace
(3) Check/clean screen
(4) Must be 30 PSI minimum
(5) Re-fill or use new container
(6) Tighten or replace tie wrap
(7) Fully squeeze nozzle to open all
the way
Too much, or too little product is
drawn Incorrect metering tip Choose the next closest ratio from chart and verify results — repeat this
step as necessary until the correct tip
is chosen
No water (or very low flow) (1) Obstruction at inlet screen area
(2) Low water pressure
(3) Scaled or clogged fittings
(1) Clean obstruction/replace screen
(2) Use a more suitable source
(3) Clean scaling or free obstructions
Supply container fills with water Checkvalve clogged Clean or replace checkvalve
NOTE: The above chart is based upon the chemical viscosity of water (CPS = 1.0) and should only be used as a
guide — the values were derived using water as the working fluid and 40 PSI dynamic input pressure. Actual ratios
and flow rates may vary due to product viscosity, flow pressure, and tubing distance(s).
