Removal
WARNINGS
Lethal voltages are present in the actuator presenting a shock hazard
to personnel. Ensure the power supply to the actuator is isolated
before the cover is removed.
If an actuator is removed from a valve fitted in a live system, the valve
rotor may rotate uncontrollably in the body. An actuator must never
be removed from a valve installed in a live system.
The actuator case can be hotter than the ambient temperature. Care
must be taken when handling the actuator to prevent burn injuries to
personnel.
1 Switch off and isolate the actuator electrical supplies.
2 Manually operate the actuator to the low temperature position.
3 Remove the actuator cover.
4 Label the wires to aid reassembly, disconnect from the terminal strip and
pull the cables clear from cable entries.
