The impeller's cover magnet has been positioned incorrectly. Call a Service Technician
The beater motor protection device has activated. Call a Service Technician.
THE MAGNETIC CONTACT AND THE RELATIVE MAGNET ARE IMPORTANT SAFETY
DEVICES AND MUST NOT BE DISABLED!
With the Main Breaker on the ON/OFF indicator [Z1] TURNS ON, but the device does not work.
Cause: Faulty internal parts or controls. Call a Service Technician.
THE DEVICE CAUSES REPEATED TRIPPING OF CIRCUIT BREAKER OR FUSES.
Cause: The capacity of the electrical supply is not sufficient to power the device.
The electrical specification of the circuit protection is not adequate.
Faulty internal parts or controls. Call a Service Technician.
THE REFRIGERATION IS INSUFFICIENT OR INTERUPTS ERRONEOUSLY.
Cause: The thermal protection of the compressor has been activated, due to excessive stress
(repeated startings, high pressure, overheating). Stop the device, wait a few minutes and try
starting again. If the device doesn't work properly, call a Service Technician.
Note: It may be necessary to wait up to 30 minutes for the thermal protection to cool down.
WATER CONDENSeR
Cause: The flow of condensation water supply is interrupted or insufficient.
The water hoses are constreted. Avoid constrictions or sharp bends.
The water condenser supply faucet/s are partially or totally closed.
The high pressure cutout valve must be adjusted or is broken, otherwise it is broken. Call a
Service Technician.
Note: To check if the water flows properly and if the high pressure cutout valve is funtioning,
temporarily detach the water outlet tube (at the end not connected at the device). Water
must flow only when the refrigeration system is in function.
The incoming water’s temperature is higher than that prescribed in the Technical Handbook.
Cause: The compressor is overheated due to a lack of ventilation. Clean the air ducts, condenser
and restore the minimal distances for the circulation of air at the sides of the device.
Note: It may be necessary to wait up to 30 minutes for the thermal protections to cool down.
Break down of the refrigeration system, or electrical controls. Call a Service Technician.
UNUSUAL NOISE.
The noise comes mainly from the tank, when beating is off.
Cause: There are solids or heavy sediments inside the tank or on the beater. Stop the machine, wait
until mixture has cooled down, empty the tank and remove obstructions.
The beater’s motor is damaged. Call a Service Technician.
The noise does NOT come from the tank, but is heard even when no beating is on.
Cause: Internl breakdown. Call a Service Technician.
