The USB interface can be charged an Apple iPad only. The USB port does not
allow data exchange.
2.4.3 Vacuum Connections
Inlet Port
The inlet port is located on the top of the PHOENIX L300i Fig. 1/1. The size of the
flange is DN 25 KF.
A test object or a test chamber has to be connected to the inlet port if the vacuum
mode is chosen (See Chapter 3.7).
The inlet port is also used for the connection of the sniffer line.
Exhaust
The exhaust Fig. 9/2 flange is located on the side of the PHOENIX L300i.
There is a filter mounted in the exhaust that absorbs the oil steams occur i ng dur-
ing the use of the rotary vane pump. The exhaust filter has to be cleaned when
doing the maintenance (see Chapter.4.4.6).
When the PHOENIX L300i is running in closed rooms the exhaust has to be put
out-of-doors using the provided adapter. So the oil steams that are harmful to
health are lead off.
With the provided connection a hose line can be connected to the exhaust of the
PHOENIX L300i and lead off.
Vent
Usually the parts under test are vented with ambient air when the test is finished. If
it is required the parts can be vented with a different gas (i. e. fresh air, dry air, nitro-
gen, …) at atmospheric pressure. In this case a vent hose has to be connected to
the hose coupling Fig. 9/1. The pressure in the venting line must nor exceed 1050
mbar.
Gas ballast connection
For the mode gas ballast it is recommended to use helium-free gases at atmo-
