6. Refrigerant Transfer with Push-Pull method
Duly connected by means of the push-pull method, the recovery unit allows the rapid transfer of the
liquid refrigerant from the refrigerant system to an external cylinder.

ARNING
Connect the recovery unit and the refrigerant circuit by means of a two-way manifold, flexible hoses with
ball valve, a cylinder with double valve (liquid-vapour) and a filter drier; these items are supplied
separately on request and must be connected as shown in the picture:
Before use, make sure that all the flexible hoses, the filter drier, the stocking cylinder and the recovery
unit have been previously evacuated or that they contain the same refrigerant as the one to be
transferred.
Make the refrigerant transfer with the cooling system turned off.
The stocking cylinder must have a capacity equal to the quantity of refrigerant that has to be removed;
anyhow, it must not be charged above 75% of its maximum capacity.
It is recommended to use an electronic scale in order to check the refilling of the stocking cylinder.
