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
collected from the system or insulated (by means of shut off valves) in a
part of the system away from the leak. Then, bleed nitrogen without oxygen
(OFN) through the system both before and after the brazing process.
7. In case it is necessary to carry out a hot work on the appliance, IT IS
NECESSARY to have a powder or CO
8. To carry out a work which includes exposition of pipes which contain or
contained a flammable refrigerant, DO NOT use sources of combustion.
Risk of fire or explosion!
9. All sources of combustion (even a lit cigarette) should be kept away from
the place in which all operations during which the flammable refrigerant
may be released in the surrounding space must be carried out.
10. Make sure the area is adequately ventilated before intervening inside the
system; a continuous degree of ventilation must be present.
11. DO NOT use means different from those recommended by the manufacturer
in order to speed up the defrosting process or for cleaning.
12. Before any operation, always check that:
• the condensers are unloaded.
The operation must be carried out safely to avoid the risk of producing
sparks;
• there are no live electrical components and that the cables are not
exposed while loading, recovering or bleeding the system;
• there is continuity in the ground connection.
13. All electrical power supplies must be disconnected from the appliance on
which you are working.
If it is absolutely necessary that the appliance has electrical power supply,
it is necessary to place a leak detector permanently operational in the most
critical point.
14. Make sure the seals and sealing materials have not deteriorated.
Possible development of flammable atmospheres.
15. Do not apply any net inductive or capacity load to the circuit without making
sure that this operation won't make you exceed the voltage and current
permitted for the appliance in use.
The appliance for the test must have correct nominal values.
15a The only components on which you can operate in flammable atmosphere
are those intrinsically safe.
The test device must be set with the correct conditions. The components
must be replaced ONLY with parts of the manufacturer. Danger of loss of
refrigerant in the atmosphere, risk of explosion.
