4.2 Starting the generator

The generator should only be operated when the inlet isolation valve is open and air is flowing at the pressure and flow
rate specified in section 2.1 of this guide. If the air flow is lost during operation, or falls below the specified requirements,
switch the generator off via the mains "ON/OFF" switch. Failure to do so could damage the internal heater.
1 Open the isolation valve at the generator inlet and adjust the pressure as required. Set the pressure relief valve to 11 bar g (159.5 psi g).
2 Referring to the recommended set up in section 3.1, connect a suitably rated flow meter in place of the silencer on the 3-way ball valve at
the outlet of the generator. Verify that the gas flow rate matches the flow rate specified in section 2.1 and adjust accordingly.
Note. The purity of the gas delivered by the generator will be affected if the specified flow rate is exceeded. If the application instrument
does not have an integral flow controller, it is recommended that a flow controller be installed downstream of the generator outlet (refer to
recommended system layout).
3 Check system piping and fittings for leaks and repair as required.
4 Switch the generator on using the mains "ON/OFF" switch located on the rear of the generator. The heating process will start immediately
and it should take approximately ten minutes for the catalyst to reach the set temperature.
5 Once the generator reaches the set temperature, open the isolation valve located downstream of the generator.
Note. The temperature may fluctuate up to 1% of the set temperature.
6 The application instrument is now being supplied with hydrocarbon free air.
The generator is designed to operate continually without user intervention.

4.3 Shutting down the generator

1 Referring to the recommended set up in section 3.1 of this manual, slowly close the three way isolation valve to divert the flow from the
application instrument to the silencer.
2 Switch the generator off using the mains "ON/OFF" switch, located on the rear of the generator, and leave it to cool.
3 After approximately 20 minutes close the compressed air supply isolation valve and wait until the pressure gauge on the inlet of the
generator reads 0 bar g.
The generator is now shut down and fully depressurised.
