When servicing the valve and/or actuator: switch OFF the pump and power Warning ! supply, close the main shut-off Special notes on this subject will be found in the mounting instructions for the ASK40 and ASK41 (mounting kits for non-Siemens valves). This may be necessary when using non-Siemens valves. However, the angle can be changed to rotation between 70° and 180°. Setting the angle of The angle of rotation is factory-set to 90°. Commissioning When commissioning the complete motorised valve, consist Refer to the mounting instructions for the valve concerned (butterfly or slipper valves). Take care to install the valve the right way up. There is no need for special tools or calibration. The valve and actuator can be assembled easily on site. The valve, actuator and mounting kit are packed separately. Mounting Mounting instructions are enclosed with the mounting kit. Accessory ASC9.4 1 dual auxiliary switch.
