Risk of electric shock.
▶Before reaching into the 0290, switch off the power supply and
secure to prevent reactivation.
▶Observe applicable accident prevention and safety regulations for
electrical equipment.
Risk of burns/Risk of fire if used continuously through hot device
surface.
▶Keep the device away from highly flammable substances and media
and do not touch with bare hands.
Risk of injury due to malfunction of valves with alternating
current (AC).
Sticking core causes coil to overheat, resulting in a malfunction.
▶Monitor process to ensure function is in perfect working order.
Risk of short-circuit/escape of media through leaking screw
joints.
▶Ensure seals are seated correctly.
▶Carefully screw valve and connection lines together.
Opening the valve briefly
If the pressure increases suddenly with the valve closed, the valve
may open for a short time.
▶Take safety precautions as required with hazardous media.

continuous operation: If standstill for a long period at least
1-2 activations per day are recommended.
Service life
High switching frequency and high pressures reduce the service life.

5.2 Before installation
Installation position: Installation can be in any position.
Preferably: Actuator upright.
→Prior to installation check pipelines for dirt and, if required, clean.
Dirt filter: To ensure that the solenoid valve
functions reliably, a dirt filter (≤ 400 µm) must
be installed in front of the valve inlet.
NOTE!
For devices with approval according to the European Gas Appli-
ances Directive it is essential to install the filter.
5.3 Installation
Sealing material must not get into the device.
→Hold the device with a suitable tool (open-end wrench) on the
body and screw into the pipeline.

The arrow on the body indicates the direction of flow (no function
in opposite flow direction).
5.4 Electrical installation
DANGER!
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!
Danger of electrical shock if the protective conductor contact
between the coil and body is missing.
▶Always connect protective conductor.
▶Check electrical continuity between coil and body.
Risk of short-circuit or escape of media through leaking screw
joints.
▶Ensure seals are seated correctly.
▶Carefully screw together coil and device socket or valve and
pipelines.
