QUIETQUBE® MODELS - FREEZE CYCLE
REFRIGERATION SYSTEM OPERATIONAL
ANALYSIS TABLE PROCEDURES
The following is the procedures for completing each step
of the Freeze Cycle Refrigeration System Operational
Analysis Tables. Each procedure must be performed
exactly for the table to work correctly.
Before Beginning Service
Ice machines may experience operational problems
only during certain times of the day or night. A machine
may function properly while it is being serviced, but
malfunctions later. Information provided by the user can
help the technician start in the right direction, and may
be a determining factor in the final diagnosis.
Ask these questions before beginning service:
• When does the ice machine malfunction? (night, day,
all the time, only during the Freeze cycle, etc.)
• When do you notice low ice production? (one day a
week, every day, on weekends, etc.)
• Can you describe exactly what the ice machine seems
to be doing?
• Has anyone been working on the ice machine?
• During "store shutdown, " is the circuit breaker, water
supply or air temperature altered?
• Is there any reason why incoming water pressure
might rise or drop substantially?
