Installation Notes
• Installation instructions for the valve and terminal housing are enclosed with the valve.
• For electrical installation, see Wiring Diagrams.
CAUTION:
• Always disconnect the power before fitting or removing the terminal
housing. The terminal housing is calibrated and matched to the actuator,
and should be replaced only by qualified personnel.
• Valve may only be used in flow direction (A → AB). Note the flow
direction.
• Do not allow the surface temperature of the actuator to fall below the
dew point temperature of the surrounding air (causing condensation).
If necessary, insulate the valve. Do not insulate the actuator.
Mounting Position
Vertical to horizontal mounting:
Do not mount the valve below horizontal.
