) shall be connected to the system.
NOTICE
The design pressure of high pressure side of the
connected refrigeration parts MUST be 9 MPaG (90 bar
gauge).
NOTICE
If the design pressure of the gas piping of refrigeration
parts is different from 90bar gauge (for example: 6 MPaG
(60bar gauge)), a safety valve MUST be installed on the
field piping according to this design pressure. It is NOT
possible to connect refrigeration parts with design pressure
below 60bar gauge.
