DETERGENT, RINSE AID, SANITIZER DISPENSERS – Tubing Installation
Detergent, rinse aid and/or sanitizer dispensers (not provided by Stero) must have all connections sealed against
leakage.
The dishwasher uses .97 gallons of rinse water per rack at a flow rate
of 5.8 gallons per minute at 20 psig flowing pressure. This informa-
tion is used when setting the detergent, rinse aid or sanitizer pumps.
Detergent Dispenser
The dishwasher has two
7

8
" diameter plugged holes, one on the rear
of the chamber and one on the lower part of the tank near the pump
(Figure 12). With the tank empty, remove both plugs to install the
detergent dispenser.
• The chamber hole is for installation of the detergent feeder
tube.
• The lower tank hole is used for installation of the detergent
sensor.
Rinse Aid Dispenser
The rinse line flange connector on top of the dishwasher has two

pipe plugs (Figure 13).
• Remove the plug(s) (Figure 13) for installation of the rinse aid dis-
penser tube and / or chemical sanitizer tube, as needed.
Chemical Sanitizer Dispenser
When the dishwasher is to be operated in the chemical sanitizing mode,
the machine must be converted to low-temperature sanitization (refer to
Setup, page 14). A chemical sanitizer dispenser that has been tested and
certified by NSF International must be installed.
• Remove the pipe plug (Figure 13) for installation of
the chemical sanitizer tube. To assure an unobstructed
flow of sanitizer, locate the sanitizer tube in the center
of water flow by drilling the sanitizer tube fitting so
that its inside diameter is equal to the outside diame-
ter of the tube. Slide the tube into the flange until it
touches the opposite side and then pull it back out
