Safety instructions

DANGER!

Risk of injury from high pressure in the system.

 

▶

Before loosening lines and valves, turn off the pressure and 

vent the lines.

Risk of injury due to electric shock.

 

▶

Before reaching into the system,

 

switch off the power supply 

and secure against reactivation.

 

▶

Observe the applicable accident prevention and safety regu

-

lations for electrical devices!

WARNING!

Risk of injury due to improper maintenance work.

 

▶

Maintenance may be carried out by authorised technicians 

only.

 

▶

Use an open-end wrench, never a pipe wrench, to screw the 

valve body or actuator in or out, and observe the tightening 

torque.

Risk of injury due to unintentional activation of the system 

and uncontrolled restart.

 

▶

Secure the system against unintentional activation.

 

▶

Following maintenance, ensure a controlled restart.
