Leak Test; Oil Injection - TEXA Konfort 700R Series Manual

Konfort Series 700R Service Manual

2.2.4 Leak Test

During this phase, the equipment activates only the pressure sensor (1).
Spent the amount of time set for the vacuum phase, the vacuum pump
turns off and the two electro-valves EVP01 and EVP02 close. At this
point, the pressure sensor performs a further control of pressure inside
the A/C system (for an amount of time preventively selected from the
initial menu of the equipment).
If, within this laps of time, the pressure rises above the limit value of
120mBars absolute, the unit will automatically stop the cycle, by putting
itself into a stand-by state and by alerting the operator (by means of a
beep and of a special message on the display) about
(indicative, in this case, of a possible leak on the A/C system of the
vehicle). If, on the other hand, the remaining pressure is below this
threshold, the operative cycle of the Konfort unit automatically switches
to the next step.
