5.  Installation

On delivery, the actuator is in the mounting 

position. 

In the mounting position, the stem is fully 
retracted and the DIP switches (Bit 1 bis 6) are 

set to "OFF" (see section 5.3.1 on page 12

). 

5.1  Fitting of the actuator

Make sure that there is enough space for the 

installation of the actuator.

The actuator must only be connected to the 

power supply after installation!

CAUTION

Risk of burns due to hot components

An unprotected contact with hot components 

may lead to burns.

 

f

Before starting work, let the valve cool 
down.

 

f

Wear safety gloves.

1.  Fit the adapter set to your valve according to the 

enclosed installation instructions.

2.  Fit the actuator to the connection thread of the 

valve.

3. 

Hand tighten the collar nut.

Avoid cross threading.

NOTICE

Damage to the actuator when tightening 

the collar nut with excessive torque 

The actuator can be damaged and its 
be function impaired if the collar nut is 
over-tightened.

 

f

Hand tighten the collar nut.
