Service flap

On the left side of the housing there is a service
flap. Behind the service flap are the fresh oil bottle,
the used oil bottle and the UV dye bottle.
i
The service flap is magnetically secured, enabling
simple fastening and removal.

Scales for refrigerant, fresh oil and used oil

There are various scales for checking the quantities of
refrigerant, UV dye, fresh oil and used oil.
!
Do not exert excessive force when removing or in-
serting the UV dye, fresh oil and used oil bottles, as
this could damage the scales.
4.4.9 Service hose and service quick-release
coupling
!
The connected hose length is provided in the parame-
ters of the software to precisely calculate the refriger-
ant quantity. For this reason, any change to the hose
length must be entered into the software settings in
the "HOSES LENGTH" menu (see Sect. 11.3).
i
When not in use, the service hoses can be wound
up on the side of the ACS 652 and fixated with the
service quick-release couplings.
i
Turn the knurled part of the service quick-release
coupling clockwise to open the valve. A counter-
clockwise turn closes the valve.
i
To remove the service quick-release couplings from
the holders, press the coupling slightly towards the
connection and carefully pull the knurled section
back to unfasten it from the holder.

Description of function

The refrigerant recovered from the air conditioner
passes through the combo filter to remove suspended
particles and moisture.
The purpose of the vacuum pump is to generate a
vacuum in the air conditioner and to detect possible
leaks in the vehicle air conditioner.
Used oil separated from the recovered vehicle refriger-
ant flows into the used oil bottle.
The compressor oil in the fresh oil bottle (PAG or POE)
is used to refill the compressor oil in the air-condition-
ing system.
The vehicle air conditioner is partly filled with UV dye to
facilitate the detection of leaks in the event of damage
to the vehicle air conditioner.
The refrigerant in the internal refrigerant cylinder is
used for filling the vehicle air conditioner.
The venting unit for non-condensable gases always
takes effect when the vessel pressure is higher than the
saturation pressure.
