PROCEDURE FOR EMPTYING AND
REFILLING THE AIR-CONDITIONING
SYSTEMS WITH R134A REFRIGERANT
R134A
refrigerant
recovery
and
refilling
station (99305146)
This station has been made to be used on all air-conditioning/
heating systems for motor vehicles using R134A gas.
By connecting the station to a refrigerating system the gas it
contains can be recovered, cleaned and made ready to be
reloaded into the system or be transferred to an external
container. In addition, it is possible to see the amount of oil
taken from the system, restore it and ”empty” the system.
To be operative, the station needs to absorb approximately
3 kg of refrigerant.
For prompt use it is advised to have at least 2 kg of refrigerant
in the filler cylinders and to keep the station as level as possible.
The station is composed of:
1
control panel;
2
container to restore any oil recovered when unloading;
3
flexible hoses;
4
container to collect any oil recovered from the system;
5
filler cylinder with graduated scale revolving.

This procedure does not describe the phases of
loading and unloading refrigerant to and from
external and internal containers or maintenance.
Therefore, please refer to the operating and
maintenance manual of the appliance.
