ADJUSTMENT PROCEDURES
A. ADJUSTMENT OF THE CUBE SIZE
CAUTION. Before performing actual
adjustment of the cube size , check other
possible causes for cube size problems,
refer to the Service Diagnosis Section for
problem review and analysis.
Do not perform any adjustment till the
icemaking system has progressed
through several complete freezing and
harvest cycle, to observe size and quality
of ice cubes and whether or not the cube
size problem exists.
I. If the cubes are shallow size (Indentation is
too deep) probably the length of the second
phase of the freezing cycle is too short so, to
extend such length you have to:
1. Locate the DIP SWITCH on the front of the
P.C.Board.
2. Take note of the combination of the first four
DIP SWITCH KEYS and check the corrisponding
length of freezing cycle 2nd phase on Table B.
3. Set the same DIP SWITCH KEYS to
correspond to the prior combination shown on
Table B which allow an extention of two more
minutes of the length of the freezing cycle.
4. Observe the ice cubes in the next two
harvests and eventually repeat steps 2 and 3
above until proper ice cubes size is achieved.
See figure.
II. If the cubes are oversize size (Indentation is
too full) probably the length of the second phase
of the freezing cycle is too long.
To shorten such length you have to:
1. Locate the DIP SWITCH on the front of the
P.C.Board.
2. Take note of the combination of the first four
DIP SWITCH KEYS and check the corrisponding
length of freezing cycle 2nd phase on Table B.
3. Set the same DIP SWITCH KEYS to
correspond to the next combination shown on
Table B which allow a reduction of two minutes of
the length of the freezing cycle.
4. Observe the ice cubes in the next two
harvests and eventually repeat steps 2 and 3
above until proper ice cubes size is achieved.
See figure.
