PRELIMINARYOPERATIONS
Checkthatswitch(j) issettoposition 0.Checkthatall the machine tapsare closed.Connect the
machine tothe electrical supplyand switchon.Checkthatthe vacuumpumpoil level indicator shows at
least one-halffull.Ifthe level islower,add oil asexplained in the MAINTENANCEsection.Checkthatin
the top-up oil container (e) there are atleast 100 cc ofthe oil recommended bythe manufacturer ofthe
vehicle A/Csystem. Checkthe level ofthe oil in container (m)(<200 cc).Checkon the machine display
thatthere are atleast 3kgofrefrigerantin the bottle.Should thisnotbe the case,fill the machine bottle
froman external bottle ofappropriaterefrigerantfollowing the procedure described in the ROUTINE
MAINTENANCEsection.
PURGENONCONDENSABLEGAS
Beforeeveryservice,check ifthereisairintothe bottle;press the temperaturebottlekey(ref
.12 fig.9)and read the temperatureof the bottle. Comparethe bottlepressurewiththe one into
the table;ifthe bottlepressureifhigherofthe pressureread on the table,pull the ring ofthe
securityvalveand bring back the bottlepressuretothe tablevalues.Example:Bottle
temperature=20 °C, the bottlepressuremust bring back at 5,2bar.
