For built-in models (page 1) check that any remnant packaging does not touch the condenser's ventilator, as this can cause a loud noise.
Replace faulty ventilator(s) (only to be completed by specialist technicians)
Generally, the most sensitive ventilator in this regard is the condenser's ventilator, which on inbuilt models, is located at the rear next to the housing of the compressor.
Due to its angle, it can sometimes slightly misalign generating a noise.
2.9 Sensors: Error codes and solutions (only to be completed by specialist technicians)
Ref.: CV48AD – CV70AD
If the display shows code "EH", the temperature sensor is faulty.
Contact the Climadiff After Sales Service department to find out based on the serial number of the device, if the unit can be replaced.
Ref.: CV48AD – CV70AD: red light permanently lit up
The red light lights up for prolonged periods if:
The required temperature is reached (in standby mode)
The device is located in an area that is too cold (refer to the specifications)
The temperature must be modified to increase the temperature: the device and its contents must slowly increase the temperature to reach the new set point.
The DOLCE VINA1 (amber display) cannot be repaired, while the DOLCEVINA2 (bluish display) can be repaired.
Ref.: CV22IX, CV52IXDZ, CV41DZX, CV44E, CV42TWIN, CV44SV, AV42XDP, CV168EI CV168EIDZ,
CV112EI, CV112EIDZ, AV121XDZ, AV154XDZ, AV143X3Z, VSV154
1. If the temperature display shows "E1": there is a connection problem with the sensor in the cooling compartment. Replace the sensor.
2. If the temperature display shows "E2": there is a problem with the sensor in the cooling compartment short circuiting. Replace the sensor.
3. If the temperature display shows "E3": there is a connection problem with the sensor on the vaporizer. Replace the sensor.
4. If the temperature display shows "E4": there is a problem with the vaporizer's sensor short circuiting. Replace the sensor.
MT-01 Indice 0 Page 55
5. If the temperature display shows "E7": there is connection problem with the sensor in the cooling compartment. Replace the sensor.
6. If the temperature display shows "E8": there is a problem with the sensor in the cooling compartment short circuiting. Replace the sensor.
If the display shows 37°C, 99F or a "continuous" symbol on some models that have an old version of the control panel, replace the sensor.
7. If the temperature display shows "HI" (with regard to: AV143X3Z): "HI" on the display indicates that the device's internal temperature is above 23°C after ten hours of operation.
Complete the following checks:
1. Connect and disconnect the device to the wall socket.
Adjust the temperature of the top and centre compartments to 5°C, the lower compartment to 12°C (on models with three areas) or the top one to 5°C and the lower one to 12°C
(models with two areas).
2. Leave the device to operate empty for two to three hours.
After having completed these tasks:
1. If the external ventilator and the compressor are working correctly but the two or three areas are not reaching the previously stipulated temperatures there is a gas leak or an obstruction on the circuit.
2. If the higher compartment reaches the required temperature (on models with three areas) or the other compartments (on models with two areas) cannot reach the temperature despite all of the ventilators working correctly, the refrigeration valve is causing the problem and in this instance should be replaced.
Inconsistent symbols on the display (compression cabinets):
Start by disconnecting the device for several minutes by removing the plug from the power supply and then plugging it in again.
Sometimes this is enough to reboot the device.
Please note that if the power supply is disconnected for a prolonged period, the factory settings are restored.
Otherwise replace the control and display panels.

Ref.: AV24XI, AV45XDZI, AV46CDZI, AV79XDZI, AV80CDZI, AV93X3ZI
If the temperature display shows “EH or EL” the sensor is faulty. Replace the sensor.

CV52IXDZ: Replacing the condenser
1. Cut tube "A" on the compressor and allow the gas to escape.
2. Heat contact points "B" and "C"
using a soldering iron.
3. Remove screws 1, 2 and 3 using a screwdriver, then remove the condenser.
4. Put the new on in place, rinse the circuit and refill with gas.
