Installation notes
• The MXG461B.. valves are flat-faced allowing sealing with the gaskets provided
• Do not use hemp for sealing the valve body threads
• The actuator may not be lagged

Maintenance notes
The valves are maintenance-free.
The low friction and robust design make regular servicing unnecessary and ensure a
long service life.
The valve stem is sealed from external influences by a maintenance-free gland.
If the red LED is lit, the electronics must be recalibrated or replaced.
Should the valve electronics prove faulty, the electronics module must be replaced by
the ASE12 replacement electronics module (refer to Mounting Instructions
74 319 0404 0).
Always disconnect power before fitting or removing the electronics module.
After replacing the electronics module, calibration must be triggered in order to
optimally match the electronics to the valve (refer to «Calibration»).
Disposal
The actuator must not be disposed of together with domestic waste. This applies in
particular to the PCB.
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.
