CONNECTION TO THE SYSTEM
Refer to Fig.4.
1) Use the correct seat of the rotating disk for the section of the component to be
connected to the rubber cone.
2) Connect the rubber cone of the clip from the red hose (HP) to the inlet of the
component to be flushed, and the clip from the blu hose (LP) to the outlet of the
component to be flushed.
NOTE: could be used also a adapter fitting (ref.C, fig.1) if supplied by the vehicle
manufacturer (Refer to Fig.5)
ENABLING THE FLUSHING KIT
If flushing kit must be enabled (not always, depending on machine model), select OPTIONS
(under CONFIGURATION or SETUP), then enter the code 43210791.
Select A/C SYSTEM FLUSHING, then enter the requested ACTIVATION CODE (retrieved with
the option kit). If the enabler code is not available, call the Service Center.
USING THE FLUSHING KIT
When flushing a system we recommend disassembling the filter and the expansion valve, in
the case of a traditional system, or only the capillary valve in the case of a flooded system. Use
the inlet to the evaporator as washing inlet and the outlet of the condenser as flushing outlet.
1 – MANUAL
In order to flush the A/C system (or one component) using any station recovery-recycling and
operate as follows:
1) Do 10 minutes of vacuum inside the system (or component)
2) Make a filling of 2 to 3 kg of refrigerant
3) Recover the filled refrigerant
4) Drain the oil (separated during recovery)
perform steps 2, 3 and 4 for three times, after which check the oil discharged from the last
cycle, if greater than 10cc make a further round of filling - recycling - waste oil (as in
paragraphs 2, 3 and 4 ).
After the washing operation, disconnect everything and unplug the machine from the power
supply.
NOTE: Every three or four washes remove the cylinder Y filter cap of the receiver, remove the
filter inside and clean it with compressed air.
