Operation
3. Operation
3.1. Initial Setup
3.1.1. Auto Fill Timer/ Auto Re- Fill Timer
Both timers for the CMA-44 are set at the factory. When the power button is
activated, the machine should fill until it begins to overflow into the scrap tray, at
which point it should stop filling.
If necessary, adjust the time set on the Auto Fill Timer to allow an appropriate
amount of water flow to properly fill the Dishmachine.
After the auto-fill is timed out the refill system is energized which will add water to
the wash tank if the water level gets below the float line, and then after sensing
water, will fill for a short (adjustable) period of time.
If necessary, adjust the time set on the Auto Re-Fill Timer to allow an appropriate
amount of water flow to properly re-fill the Dishmachine.
3.1.2. Auto Fill Timer (Old Models)
When Auto Fill is activated, the machine should fill until it begins to overflow into the
scrap tray, at which point it should stop filling.
If necessary, adjust the time set on the Auto Fill Timer to allow an appropriate
amount of water flow to properly fill the Dishmachine. See Section 5.2.2 Control
Box Assembly Item
3 ( Note: With the Auto Fill option there are two timers in the
control box. The Auto Fill Timer is in the upper-right corner of the control box).
Users note: If at any time less than a full Auto Fill cycle is desired, the Auto-Fill
can be interrupted (stopped) by turning off the power to the machine. The machine
will resume normal operation upon restoring power without continuing the Auto Fill
cycle.
3.1.3. Rinse Pressure Regulator
The CMA-44 requires a supply water pressure of 24 PSI minimum. The pressure is
then reduced by the supply water regulator. Use the following procedure to adjust
the rinse pressure to 20 PSI:
1. Close the door on the machine.
2. Turn the Power switch to the "ON" position.
3. Using a rod or something long to avoid contact with the rinse water, actuate
the final rinse trip switch—this activates the water solenoid. With the rinse
water flowing adjust the pressure regulator until the gauge reads 20 PSI.
Adjustment tip: Always adjust “down” when setting this pressure regulator. In
other words—intentionally raise the pressure above the desired set point and
then carefully bring it down to the correct pressure.
3.1.4. Wash Tank Temperature
The wash tank temperature for the CMA-44 is set at the factory. Should you ever
find a need to adjust it—after replacement of the thermostat for example—simply
perform steps 1 through 4 in section
3.2 Beginning Operation.
