Mounting notes
The valve should be mounted and commissioned by qualified staff. The same applies
to the replacement electronics and the configuration of the controller (e.g. SAPHIR or
PolyCool).

• The refrigerant valve can be mounted at any angle from
upright to horizontal, but must not be suspended below the
horizontal
• Pipework should be arranged such that the valve is not
located at a low point in the plant where oil can collect
• The valve must not be fitted with the help of its bracket
• The valve body and the connected pipework should be lagged
• The actuator must not be lagged
The valve is supplied complete with Mounting Instructions 74 319 0468 0.
The refrigerant valve is maintenance-free.
Maintenance
Repair
If the valve’s interior is subjected to great wear, the valve can be repaired by fitting an
ASR…N replacement insert.
Disposal
The actuator contains electrical and electronic components and must not be disposed
of together with domestic waste.
Legislation may demand special handling of certain components, or it may be sensible
from an ecological point of view
Current local legislation must be observed.
Warranty
Application-specific technical data must be observed.
If specified limits are not observed, Siemens Building Technologies / HVAC
Products will nor assume any responsibility.
