6.12.2 Test N2H2
CAUTION: A too fast adjustment knob
opening could cause damage to the system!
For no reason the output pressure must be
greater than the pressure required for the
operation to be carried out and in any case
it must not be greater than 14 bar.
CAUTION: In the case of malfunctions
such as leakage from the gauges, gaskets,
fittings, connection hose or pressure
regulator, immediately stop using the
reducer and close the cylinder valve.
Replace damaged components with
equivalent certifates for use.
CAUTION: Disconnecting the hose with high
internal pressure is extremely dangerous.
Always perform this operation with extreme
caution, being careful to fully disconnect
the hoses only when the internal pressure
of the system has reached the atmospheric
pressure.
1. Select N2H2 Leak Check.
2. Connect the N2H2 cylinder hose to the N2H2 or N2
input port on the station and confirm with
.
3. Adjust the external N2H2 cylinder to a pressure
value between 8 and 12 bar and confirm with
.
4. Connect both service hoses to the vehicle service
connections and open the valves of the service
hoses turning the ring nuts clockwise.
5. Select
to continue.
6. The station pressurizes the A/C system of the
vehicle.
7. When the pressure is stabilized, the station requires
the operator to search for leaks with an electronic
leak finder.
