4.2 application conditions
Ambient temperature Type 0256: max. +55 °C
Type 0285: max. +60 °C
Operating duration Unless otherwise indicated on the type label,
the solenoid system is suitable for continuous
operation
Important information for functional reliability during continuous
operation! If standstill for a long period at least 1-2 operation
per day are recommended.
Service life High switching frequency and high pressures
reduce the service life

5.1 safety instructions
Danger!
Risk of injury from high pressure in the equipment!
▶ Before loosening the lines and valves, turn off the pressure and vent
the lines.
Risk of injury due to electrical shock!
▶ Before reaching into the system, 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 improper installation!
▶ Installation may be carried out by authorized technicians only and
with the appropriate tools!
Risk of injury from unintentional activation of the system and an
uncontrolled restart!
▶ Secure system from unintentional activation.
▶ Following installation, ensure a controlled restart.
5.2 Before installation
Installation position: any, actuator preferably upwards.
Procedure:
→
Check pipelines for dirt and clean.
→
Install a dirt filter before the valve inlet (≤ 500 µm).
5.3 installation
note!
Caution risk of breakage!
• Do not use the coil as a lifting arm.
→
Hold the device with a open-end wrench on the body and screw
into the pipeline.
→
Observe direction of flow:
The arrow on the body indicates the direction of flow.
