2.2.3. Chemical Dispensers
*
This machine must be operated with an automatic detergent feeder and, if applicable, an
automatic chemical sanitizer feeder, including a visual means to verify that detergents and
sanitizers are delivered or a visual or audible alarm to signal if detergents and sanitizers are not
available for delivery to the respective washing and sanitizing systems. Please see instructions
for electrical and plumbing connections located in this manual and in the feeder equipment
manual.
1. Check valves should be installed directly at the mixing chamber coupling located by the
vacuum breaker on the back of machine. There are two 1/8” FPT mounting holes
provided on the mixing chamber coupling, which will position the check valves parallel to
the machine avoiding any chemicals from dripping onto the stainless steel should a leak
develop. One hole is for rinse chemical and one for sanitizer chemical, but only one is
needed with the High Temp machines — for rinse chemical only.
2. Remove the plugs from the mixing chamber; and install injection fittings (supplied with
your dispenser).
3. A 7/8” detergent injection hole is provided in the back of the wash tank. Remove the S.S.
plug and install the detergent fitting (supplied with your dispenser).
4. A 7/8” chemical probe hole is provided in the front of the wash tank heater just below hi
limit switch. Insert the probe into the hole from inside the wash tank and secure it with the
probe retaining nut provided.
2.2.3.1. Low Temperature Applications
See dispenser manufacturing operational instructions for sanitizer adjustments for Low
Temp applications.
The sanitizing pump operates when the fresh water enters the machine during final rinse.
The water is treated at 50 PPM (parts per million). The pressure regulator is adjusted to
20 PSI. This allows 0.82 gallons of water to enter the machine each time a rack is
washed.
It is recommended that the 5-1/4% chemical solution be standardized to allow uniform
dispensing of the sanitizing solution into the flow of rinse water as the machine operates.
At this level, maximum shelf life is available.
Note: Use only commercial-grade detergents and rinse aids recommended by your
chemical professional. Do not use detergents and rinse aids formulated for residential
dishwashers.
Low Temperatures chemical-sanitizing dishmachines must not exceed 6% sodium
hypochlorite solution (bleach) as the sanitizing agent. Higher levels may damage
stainless or components.
Follow the directions precisely that are on the litmus paper vial and test the water on the
surface of the bottom of the glasses.
