Technical Remarks
■	The pressure dew point must be at least 15 °C under ambient and medium temperature and may not exceed 3 °C.
■	The oil content of air pressure must remain constant during the life cycle.
■	Use only the approved oils from Bosch Rexroth, see chapter „Technical information“.
■	*) Note: ATEX variants can be manufactured by combining the basic valve without a coil with a CNOMO pilot valve, series DO30, and an ATEX coil. ATEX ID: see ATEX coils catalog sheet.
