DETERGENT, RINSE AID, SANITIZER DISPENSERS — TUBING INSTALLATION
Detergent, rinse aid and / or sanitizer dispensers (not provided by Hobart) must have all connections
sealed against leakage.
The dishwasher uses 0.74 gallons of rinse water per rack at a
flow rate of 4.4 gallons per minute at 20 psig flowing pressure
(equivalent to a maximum head pressure of 46 feet of water).
This information 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 (Fig. 19). 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
1
/8" NPT pipe plugs (Fig. 20).
• Remove the plug(s) (Fig. 20) for installation of the rinse aid
dispenser 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 16). A chemical sanitizer
dispenser that has been tested and certified by NSF International
must be installed.
• Remove the pipe plug (Fig. 20) 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 diameter of the
tube. Slide the tube into the flange until it
touches the opposite side and then pull it back
out
1
/4 inch (Fig. 21).
• Rate for 6% Sodium hypochlorite (bleach) —
3 ml. within 10 seconds (maximum).
• Rate for 8.4% Sodium hypochlorite (bleach) —
2 ml. within 10 seconds (maximum).
