The quick connections are specifically designed
for refrigerant management according to the SAE
standard.
1. Lubricate the o-rings of the service hoses (HP and LP)
with an oil film.
2. Screw the high pressure service hose (red) to the
HP connection on the station.
3. Screw the low pressure service hose (blue) to the
LP connection on the station.
4. Tighten both service hoses with a tightening torque
of 7.9 Nm.
i
If not used, service hoses can be wound on the back
of the station.
5.5 Use of oil and UV dye tanks
!
Only use UV contrast liquids and oils that are
approved by the vehicle manufacturer. This prevents
chemical incompatibility with the station internal
components.
In the event of problems and failures due to non-
approved liquids, the warranty will be void.
i
The following procedure is necessary to minimize
the amount of air in the tanks.
1. Unscrew the "PAG", "POE", "UV Dye" tank covers and
remove them with the 3 pistons.
2. Fill the 3 tanks with compressor oil for PAG and POE
or UV dye at maximum to the "MAX FILL" line.
3. Lubricate with an oil film the o-rings of the 3 pistons
to reduce friction on the tanks.

them, make sure that each of them is aligned with
the respective bracket/fitting and have a slight
pressure in the straight direction to the station.
