Installation
M518-00-880 Issue A
3.3 Connect the pump inlet and outlet
Use a catchpot to prevent the drainage of condensate back into the system. Condensate that drains back into
the system could damage the pump.
Do not re-use any O-ring or O-ring assembly and do not allow debris to get into the system during installation.
If you have a CXS/EH combination system with flame arresters, these must be fitted to the inlet
and exhaust flanges as detailed in the CXS Manual M52800880. The inlet flame arrester is supplied
fitted to the CXS/EH combination system, however the exhaust arrester is supplied separately,
secured to the pallet, and must be fitted.
If you have a CXS/EH combination system with flame arresters, these must be fitted to the inlet
and outlet flanges of the pump as specified in the CXS Manual M52800880. No other positions or
modifications are permitted without consulting Edwards. Otherwise, there may be a risk of injury
or death to people and damage to equipment and facilities.
Obey the safety instructions given below. If you do not, the installation may not be safe, and there
may be a risk of injury or death to people.
Pipe the exhaust to a suitable treatment plant to prevent the discharge of dangerous gases or
vapours to the surrounding atmosphere.
Do not operate the system with the exhaust pipeline blocked. If the exhaust pipeline is blocked,
the system can generate exhaust pipeline pressures of up to 12 bar (12 x 10
5
Pa).
Ensure that all components in the process pipeline have a maximum pressure rating which is
greater than the highest pressure that can be generated in your system.
