2.10 Supply pressure
Do not apply pressure until electrical connections are made. When applying pressure to the system, take
care to avoid pressure shocks in the system and increase pressure gradually, especially on high pressure
units incorporating a piston operated control valve.
2.11 System purging
If explosive gases are to be used, purge the process with inert dry gas like Nitrogen, Argon etc. for at
least 30 minutes.
In systems with corrosive or reactive fluids, purging with an inert gas is absolutely necessary, because if the
tubing has been exposed to air, introducing these fluids will tend to clog up or corrode the system due to a
chemical reaction with oxygen or moist air.
Complete purging is also required to remove such fluids from the system before exposing the system to air.
It is preferred not to expose the system to air, when working with these corrosive fluids.
2.12 Seals
Bronkhorst

has gathered a material compatibility chart from a number of sources believed to be reliable.
However, it is a general guide only. Operating conditions may substantially change the accuracy of this
guide. Therefore there is no liability for damages accruing from the use of this guide.
The customers application will demand its own specific design or test evaluation for optimum reliability.
So check if the seals like O-rings, plunger and packing gland of capillary are correct for the process.
2.13 Equipment storage
The equipment should be stored in its original packing in a cupboard warehouse or similar. Care should be
taken not to subject the equipment to excessive temperatures or humidity.
2.14 Electromagnetic compatibility
2.14.1 Conditions for compliance with EMC requirements
All instruments described in this manual carry the CE-mark.
Therefore they have to comply with the EMC requirements as are valid for these instruments.
However compliance with the EMC requirements is not possible without the use of proper cables and
connector/gland assemblies.
For good results Bronkhorst

can provide standard cables. Otherwise follow the guidelines as stated below.
