General information on refrigerant circuit
Página 21 de 21
Note:
Some service units are charging systems not requiring a
permit. When working with such equipment, the refrigerant
is not transferred to mobile compressed-gas vessels, but
rather into a permanently installed charging cylinder with
visible level gauge and float switch.
Recommendation:
It is advisable to use a portable cylinder with visible level
gauge and pressure relief valve for surplus refrigerant for
internal use.
Attention must be paid to TRG 402 (technical regulations
for compressed gases) when transferring compressed
gases to other compressed-gas vessels.
