5.1 Problems that may occurs during operation and suggested
solutions
5.1.1 Frozen cylinder phenomena.
INFO: The frozen cylinder occurs when there is ice formation in the cooling cylinder;
this results in that the resistance on the beater and the motor become too larger for the
machine to handle and may cause serious damage to the machine. This phenomenon is
usually noticed by abnormal friction noise from the cooling cylinder and a sudden sharp
increase of the value on the display for the motors current.
HOW to avoid it
:
a. Always follow the mixing rate specified between the soft ice cream
powder and the amount of water (ex. 1 to 3 for Ocean power soft ice
cream powder)
b. Always remember to remove all the water from the cooling cylinder after
cleaning.
c. Keep balance of the amount of soft ice cream mixture in the two hoppers.
If one flavor is used very little extrude some ice cream and return it to the
hopper time after time.
d. Turn off the machine if it is not used for more then 30 min and let it “rest”
for 5 minutes or extrude some soft ice cream.
e. Always keep ice cream mixture in the hopers when the machine is on.
WHAT to do if it happens :
1. Press the STOP button or use the emergency switch to turn off the
machine and let it “rest” for at least 30 min. This is so the ice formation
has a chance to melt. .
2. Return the emergency switch to the “on” position and try to extrude some
ice cream by pulling the distribution level. If abnormal noise can be heard
or if the display for the motors current shows a high value (>5.00) use the
emergency switch to immediately turn of the machine and let it rest for an
additional 30 minutes.
3. repeat this procedure until ice cream can be dispersed by pulling the
distribution level and the machine is operating normally.
4. Finally press the Auto button, to start the production of soft ice cream
again.
5.1.2 Operation conditions that will result in “AUTO”-protection.
The “AUTO” protection will be activated if any of the operation conditions mentioned
bellow would occur. The machine will then be in stand-by condition for 10 minutes and
then return into normal operating condition.
•
Because of the “Frozen cylinder” phenomena.
•
The voltage is below 198 V, low-voltage protection.
