Important information for functional reliability during continuous
operation!
If the equipment is switched off for a long period, it is recom-
mended to activate the valves at least 1-2 per day.
Service life:
High switching frequency and high pressures reduce the service life.
The valves operate maintenance-free.

7 ASSEMBLY
7.1 Safety instructions
DANGER!
Risk of injury from high pressure in the system!
▶ Turn off the pressure and vent the lines before loosening lines or
valves.
Risk of injury due to electrical shock!
▶ Before reaching into the device or the equipment, switch off the
power supply and secure to prevent reactivation!
▶ Observe applicable accident prevention and safety regulations for
electrical equipment!
WARNING!
Risk of injury from greatly accelerated device parts and uncon-
nected whiplashing compressed air hoses!
▶ Before pressurizing the valve, check that all screw connections and
screw joints are tight and secure.
Risk of injury from improper assembly!
▶ Assembly may only be carried out by authorized technicians and
with the appropriate tools!
