In these cases the leakage points are to be discovered, repaired and the cooling circuit is to be replenished, respecting the December 28 1993 n°549 law.
25.6.1. Load procedure
The load procedure is the following:
− Empty and dry the entire cooling circuit using a vacuum pump connected to the low and high pressure socket until 10 Pa is read on the vacuum meter. Wait a few minutes and check that this value does not rise above 50 Pa.
− Connect the refrigerant gas cylinder or a load cylinder to the socket on the low pressure line.
− Load the amount of refrigerant gas indicated on the appliance features plate.
− After a few hours of functioning, check that the liquid indicator indicates the dry circuit (dry-green).
In the case of partial loss, the circuit must be emptied completely before being re-loaded.
− The R134A refrigerant must only be loaded in the liquid state.
− Functioning conditions that are different to the nominal conditions can give rise to values that are greatly different.
− The sealing test or the search for leaks must only be performed using R134a refrigerant gas, checking using a suitable leak detector.
− In the cooling circuit it is prohibited to use oxygen or acetylene or other inflammable or poisonous gases because they are a cause of explosions or intoxication.
We recommend to envision a machine book (not supplied, but the user's responsibility), which allows to keep track of the interventions performed on the unit. In this way it will be easy to suitably organise the interventions making research and the prevention of any machine breakdowns easier.
Use the date to record date, type of intervention made (routine maintenance, inspection or repairs), description of the intervention, measures actuate...
IT IS forbidden to RELOAD the circuit with a refrigerant gas different to the one indicated.
Using a different refrigerant gas can cause serious damage to the compressor.
DISPOSAL
Envisions that disposal of the unit is carried out in conformity with the Standards in force in the different countries.
