THERMOSTAT ADJUSTMENT:
Remove the front dress
panel from the machine to expose the heater/thermostat box.
Remove the cover from the heater/thermostat box. Locate the
wash tank regulating thermostat (see diagram).
The wash tank regulating thermostat will maintain the correct
wash water temperature. NSF requirements specify that the
wash water during operation be 140ºF minimum in the chem-
ical sanitizing mode and 160ºF minimum in the hot water san-
itizing mode. Adjust the thermostat to achieve the required
minimum temperatures during operation. Turn the adjustment
screw clockwise to increase the temperature set point, coun-
terclockwise to decrease the temperature set point.
Replace heater/thermostat box cover and front dress panel.
IDENTIFICATION OF SANITIZING MODE:
Apply the correct
temperature gauge label to the face of the temperature
gauges. In the chemical sanitizing mode, the temperature
gauge labels must specify 140ºF minimum wash temperature
and 140ºF minimum rinse temperature. In the hot water san-
itizing mode, the temperature gauge labels must specify
160ºF minimum wash temperature and 180ºF minimum rinse
temperature.
Apply the correct sanitizing mode label in a visible location on
the side of the control box.
INSTALL SANITIZER DISPENSER:
For machines in the
chemical sanitizing mode, a NSF Standard 29 approved
chemical dispenser must be installed to dispense sanitizer
into the final rinse line. Follow instructions included with the
chemical dispenser. The system selected must be able to pro-
vide detergent and sanitizer in the required concentrations.
The minimum chlorine concentration for proper sanitization is
50 PPM. Furthermore, the selected feeder needs to be able to
operate against a head of 25 PSI and deliver 7.38 ml of a 10%
chlorine sanitizer per minute.
FINAL CHECK:
Verify that the incoming water matches the
flow pressure and temperature requirements listed on the
machine data plate. Verify that minimum wash and rinse tem-
peratures are maintained during operation.
