Repair 

	
When repairing the actuator, comply with the following sequences: first turn off the water pump and cut off the water pump power source; close the stop valve, drain the water within the water pipe in order to reduce the pressure within water pipe, and cool the hot water pipe naturally. Remove the electrical wiring from connection terminal.

	
 

	
Re-debug the valve with the hand operated regulating knob mounted or the actuator mounted correctly.

	
Seal of valve handle 

	
The valve handle seal cannot be replaced. If it leaks, the whole valve must be replaced. So, the attention must be paid to the information provided in the “Repair”. You can contact the local office or branch of Siemens Building Technologies.

The operating temperature range (-25...+130°C) complies with DIN 4747 and DIN 3158 Standards.

Notices

	
Engineering

	
It is suggested that the valve be mounted on the return water pipe, because in the heating system, the temperature of return water pipe is relatively low. In this way, the service life of valve spool seal can be extended.

	  	  
	  	
The water quality shall comply with VDI 2035 Standard.

		
In the open system, it is possible that the valve plug may be locked due to the deposit of water scale (the valve handle cannot rise and fall normally). Thereby, such kind of application shall select SKB or SKC series of actuator with large driving force. Besides, the valve handle must be driven to operate regularly (at least two or three times a week).

	  	
Note: the valve upstream must be mounted with the filter.

	  	
It is often suggested that in the closed system, the filter be mounted in front of valve, so as to increase the operational reliability of valve.

 

	

	
When the medium temperature is lower than 0 ̈, select ASZ6.5 electronic valve handle heating element to prevent the valve spool within the sealing gland from freezing. For the sake of safety, the operating voltage of this heating element is designed AC 24V, and its power is 30 W.

	
Mounting

	
The valve and actuator can be assembled in the mounting position simply, independent of special tools and any adjustment.

	  	
The valve shall be attached with the Instruction for Mounting before leaving the factory.

Remove the electrical wiring from connection terminal. Before re-debugging the valve, correctly mount the actuator properly.

 

	
Seal of valve handle

	
When the water pipe has de-pressurized and is cooled fully, and the valve handle surface is in good condition, it is allowed to replace the seal of valve handle directly, without removing the valve body. If the valve handle has been damaged, replace the whole valve handle-valve plug assembly. Please contact the local office of Siemens Building Technologies.
