CMA Dishmachines CMA-180UC Safe Ttemp Feature, CMA -180“SafeTtemp” Installation Instructions

2.2.4. Safe Ttemp Feature

The CMA “SafeTtemp” feature assures the final rinse cycle is always at a consistent minimum of 180 degrees.

How it works: the “SafeTtemp” function operates off the 5th cam (labeled “SafeTtemp”) on the timer assembly. When the cam timer assembly completes the wash cycle, and approaches the final rinse portion of the cycle, the “SafeTtemp” micro switch will drop into the cam slot and pause cam timer assembly if the booster heater has not reached 180 degrees. Machine will remain in wash cycle mode until 180 degree rinse temperature is met, and at this time the cam timer will advance automatically into the rinse cycle and dispense 180 degrees rinse water over the dishes.

Note: if Safe Ttemp cam is not to be used, it becomes a spare cam.

CMA -180“SafeTtemp” Installation Instructions:

1)Remove the 4cam timer assembly (note wire colors and wire placement for all 4cam timer micro switches) and install 5cam timer in its place.

2)Place all wires removed from 4cam timer assembly in exact position on 5cam timer assembly.

3)The cam timer motor receives (1) yellow wire and (1) white wire (re-connect the yellow wire only from dishmachine harness to the motor).
