Operation
3.2. General
Please follow the instructions given here before each shift to assure trouble free operation.
Caution: Do not operate the dishmachine without the drain screen in place. Debris getting into the
pump impeller can damage the pump.
1. Drain the water if it is cold by lifting the drain ball until all the water is out of the machine.
2. Check the drain screen and, if needed, remove it from the machine and clean it out. After
cleaning, replace it properly into the sump housing.
3. Check the wash arm spray tips. If they are clogged, clean them with a toothpick and rinse
them at the sink. Replace the wash arms.
4. Check the chemical lines to the chemical containers.
a. Red: detergent line.
b. Blue: rinse agent line.
c. Clear/White: sanitizers destainer line.
5. Press and hold the fill switch until the water level is approximately ½” to ¾” below the
overflow hole in the PVC standpipe. The water level should be approximately even with the
bottom edge of the splash guard in the sump area of the machine.
6. Once a proper water level is established, check the temperature of the water (it should be
minimum 120F, recommended 140F, 49/60C).
7. Insert a rack of dishes into the machine and close the doors. The machine will
automatically start when the doors are closed.
8. After the machine stops, raise the doors, remove the rack of dishes (allow to dry before
stacking).
9. Insert the next rack of dishes into the machine and close the doors. Again the machine will
automatically start when the doors are closed.
10. At the end of the shift, drain the machine by lifting the drain ball out of the drain until the
machine is completely drained.
11. Remove and clean the drain screen. Remove and clean the spray arms. (See wall chart
instructions).
12. Replace the drain screen and spray arms.
If the doors are lifted during a cycle, the machine will automatically stop running.
The machine will run through the wash and rinse cycles automatically feeding the proper chemicals and
then turn itself off.
In an emergency you can turn off the machine by turning off the main power switch at the back of the
control box.
Note: It is essential that the operator thoroughly understand the importance of pre-scrapping the dishes
before loading them. All Dishmachines are equipped with a removable drain screen. The drain screen
can be easily removed for cleaning between Operational Cycles of the dishmachine. Properly pre-
scrapping the dishes should permit the dishmachine to operate for an entire shift before needing to
remove and clean the drain screen.
