• Product removal and re-cycling operations must be performed by a qualified
certified technician.
• If the system has a leak-detection device installed, the checks for leaks must
be performed at least every 12 months.
• When the unit is checked for leaks, keeping a record of all inspections is
highly recommended.
• Before starting to operate on the appliance, it is necessary to check the zone
surrounding the equipment to make sure there are no dangers of fire nor
risks of combustion.
To repair the refrigerating system, it is necessary to take the following
precautions before starting the intervention on the system.
This product must be used exclusively according to the specifications
indicated in this manual. Use different to that specified, could cause serious
injuries.
THE MANUFACTURER IS NOT LIABLE FOR INJURY/DAMAGE TO
PERSONS/OBJECTS DERIVING FROM FAILURE TO COMPLY WITH THE
REGULATIONS CONTAINED IN THIS MANUAL.
1. It is necessary to define the area around the work space and to avoid
working in tight spaces. Ensure safe work conditions by checking flammable
material.
2. All personnel in charge of maintenance and people which work in the
surrounding area must be instructed on the type work they are going to
carry out.
3. The zone MUST be checked with a specific refrigerating liquids detector
before and during work, so that the technician is aware of potentially
flammable atmospheres. Make sure the detection device of the leaks is
suitable for use with flammable refrigerants, then that it does not produce
sparks and that is adequately sealed or intrinsically safe.
4. The leaks electronic detectors may need calibration.
If necessary, calibrate them in a zone free of refrigerant.
5. Make sure the detector is not a potential source of combustion and that it
is suitable for the refrigerant used. The device for detection must be set
at a percentage of the refrigerant LFL and must be calibrated for the used
refrigerant; the appropriate percentage of gas (maximum 25 %) must be
confirmed.
5a. Fluids for the detection of losses are suitable for most part of the refrigerants.
Detergents containing chlorine MUST be avoided.
Danger of corrosion of copper pipes.
6. If the presence of a leak is suspected, all open flames must be removed.
If a fluid leak which requires brazing is encountered, all refrigerant must be
