WORKING

 

CYCLE 

 

 

 

 

 

 

 

 

 

 

 
 

 

 

Automatic A/C service cycle, with automatic or manual working parameter setting  

NOTE:  always  wear  safety  gloves  and 
protection  glasses  when  servicing  an  A/C 
system! 

 

You may  perfom the A/C service cycle in  three ways : 

 

A)

 

AUTOMATIC working cycle                all working phases performed in one step 

B)

 

MANUAL working cycle                single working phases  performed one by one  

C)

 

SEMI-AUTOMATIC working cycle              recovery, oil drain, vacuum first step. Oil/dye and gas charging made 
after the setting of the oil quantity by the user. 

 

In all cases, there is no setting needed for the recovery phase. The vacuum/vacuum test  time and the refrigerant 
quantity
  

 

1.

 

Can be taken from the  internal DATABASE or 

2.

 

Can be defined  by the user (manual setting of the parameters) 

 

The dye quantity has to be set by the user (default is 0 g)  
 
The new oil quantity, can be set in two ways:  

1.

 

It can be set by the user  with no regard  to the the recovered oil (“MANUAL”  oil setting) 

2.

 

It can be set by the user according to the recovered quantity. In this case,  the oil quantity has to be set on SA 
Pressing on the DOWN button below 0  the letters SA (“SemiAutmatic”) are displayed and the unit stops after 
the vacuum to allow the  user to evaluate the recovered oil quntity) and set the same new oil amount. 

 

A)

 

To perform an AUTOMATIC working cycle:  

 
 

 
 
Choose the vehicle’s model from the 
DATABASE   or … 

 

 
… select the AUTOMATIC CYCLE / MANUAL 
PARAMETER SETTING
 mode (drawing at the 
right) and reach the following menu 

 

 
By selecting START and clicking on ENTER, the 
unit performs an automatic cycle according to 
the displayed parameters. In the example to 
the right: 30 min vacuum, 1 min vacuum test, 
10 g of new oil, 0 g of dye, 750 g refrigerant 
charging .
