machines: bottle brush, antilime agent
* Ambient temperature too high
Provide better ventilation,
move maschine away from wall.
* Insufficient amount of refrigerant,
Remove leak, evacuate circuit,
bubbles in sight glass
replace filter drier, refill with
indicated quantity of refrigerant.
* Lime deposit on auger
Clean freezing unit with hot water and

antilime agent (Ziegra cleaning agent),
clean mechanically, if required.
* Ice breaker is misadjusted

If Ice maker is connected
* no sufficient refrigerant
check the cooling system of the

Occasional gentle squeaking noises
are a typical sign for good and hard ice,
but do not indicate a failure.

Repairs of electrical parts and refrigeration circuit only carried out by a
qualified technician!
Check refrigeration circuit (bubbles
in sight glass). Eliminate leakage,
replace filter drier, evacuate circuit,
refill refrigerant.
After leaving the cylinder the ice is
pressed due to wrong installation of the
ice discharge tube, the extension, or
due to sharp bends.
