There are several types of detector:
-electronic detectors,
-trace detectors.
Check that the air conditioning system is operating cor-
rectly (see 62A, Air conditioning, Air conditioning:
Check, page 62A-4) .
REFRIGERANT CIRCUIT SEALING CHECKING
OPERATION
1 - Electronic detectors:
a
aSwitch on the electronic detector.
aStart the engine.
aLet the air conditioning system run for 15 minutes.
aSwitch off the engine.aCheck the sealing of the refrigerant circuit using the
electronic trace detector (follow the trace of the cir-
cuit as closely as possible, to limit variations due to
other gases).
2 - Trace detectors
a
aCheck for dye on the cold loop components with the
ultraviolet light.
aInject the dye.
aStart the engine.
aLet the air conditioning system run for 15 minutes.
aSwitch off the engine.
aCheck the refrigerant circuit sealing by scanning the
circuit with the ultraviolet light.
aAffix a label (supplied with the dye capsule), to indi-
cate that dye has been used (as close as possible to
the filler valves). Equipment required
Diagnostic tool
IMPORTANT
Consult the safety and cleanliness advice and oper-
ation recommendations before carrying out any
repair (see 62A, Air conditioning, Air condition-
ing: Precautions for the repair, page 62A-1) .
Note:
After any work on air conditioning circuit leaks on
the Laguna II, Vel Satis and Espace IV, check that
filling fault DF033 Refrigerant is not present, using
the Diagnostic tool. If it is present, clear it. The
compressor cannot operate until the fault is cleared.
Note:
To carry out an after repair check, use the proce-
dure for the electronic detector (1). To carry out a
more thorough check for leaks, use a trace detector
(2).
WARNING
Consult the device's operating manual to avoid
incorrect use.
Note:
If replacing a defective part (see 62A, Air condi-
tioning).
WARNING
Consult the device's operating manual to avoid
incorrect use.
WARNING
To avoid damaging the cold loop components
(corrosions , etc.), do not use dye if the traces
reveal that some product has already been
injected.
Note:
If replacing a defective part (see 62A, Air condi-
tioning).
