ADJUSTMENT, REMOVAL AND REPLACEMENT 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 third 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 DIP
SWITCH KEYS 3, 4, 5, 6 and 7 and check the
corrisponding length of freezing cycle 3rd phase
as shown on Table C.
3.
Change the same DIP SWITCH KEYS
setting so that it will correspond to the combination
on table C coming next to the one remarked at
step 2.
This will allow an extension of the freezing cycle
of one more minute.
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 DIP
SWITCH KEYS 3, 4, 5, 6 and 7 and check the
corrisponding length of freezing cycle 3rd phase
as shown on Table C.
3.
Change the same DIP SWITCH KEYS
setting so that it will correspond to the combination
on table C pre-ceding the one remarked at
step 2.
This will reduce an the freezing cycle length of
one minute.
