6.1 safety instructions
Danger!
Risk of injury from high pressure in the equipment!
▶ Before loosening the pipes and valves, turn off the pressure and vent
the lines.
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 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 assembly, ensure a controlled restart.

6.2 fluid installation

Installation position: any, actuator preferably upwards.
Procedure:
→
Clean any possible dirt off the pipelines and flange connections.
→
Install a dirt trap to prevent malfunctions (0,2 ... 0,4 mm).
Observe direction of flow:
from 1(P) → 2(A) (circuit function A) / (circuit function C), or
1(P) → 2(B) (circuit function D).
Valve with threaded connection:
→
Use a suitable sealing material.
note!
Caution risk of breakage!
• Do not use the coil as a lever arm.
→
Hold the valve with the appropriate tool on the body and screw into
the pipeline.
