and events which may arise during installation, operation and
maintenance.
Danger – high pressure.
▶Before loosening the lines and valves, turn o the pressure and
vent the lines.
Risk of electric shock.
▶Before reaching into the system, switch o the power supply
and secure to prevent reactivation.
▶Observe applicable accident prevention and safety regulations
for electrical equipment.
Risk of burns/Risk of re if used continuously through hot device
surface.
▶Keep the device away from highly ammable substances and
media and do not touch with bare hands.

Medium leaking through damaged connections.
▶Do not damage sealing surfaces of the body connections.
Danger due to unsuitable screw connections.
▶Use compatible screw connections only.
→Check pipelines for dirt and clean.
→Install a dirt lter before the valve inlet (0,2...0,4 mm).
Installation position: any, actuator preferably upwards.
NOTE!
Caution risk of breakage.
▶Do not use the coil as a lever arm.
Valve body must not be installed under tension.
Sealing material must not get into the device.
→Seal the pipe connection with an elastomer seal or PTFE tape.
Ensure that no sealing material gets into the device.
→Observe direction of ow: from 1 → 2 (from P → A).
→Hold the device with a open-end wrench on the body and screw
into the pipeline.
5.1 Installation of coil
WARNING!
Risk of escape of media.
When a sticking nut is loosened, medium may escape.
▶Do not tighten sticking nut any further.
Risk of injury due to electrical shock.
If the protective conductor contact between the coil and body is
missing, there is danger of electrical shock.
▶During installation insert the plastic ring into the body journal. The
plastic ring must not project over the octagonal nipple.
▶Check protective conductor contact after installing the coil.
Overheating, risk of re.
If the coil is connected without a pre-installed valve, the coil will
overheat and be destroyed.
▶Connect the coil with a pre-installed valve only.
