Operating and installation instructions
Thrust actuator ARI-PREMIO
- Mains fuse rating max. 6A.
- Circuit breakers in the plant to cut off the mains supply to the actuator.
- Conformity of technical data on thrust actuator with field conditions.
- Mains voltage in accordance with data specified on rating plate of thrust actuator.
- Thrust actuator complete with yoke or distance columns and coupling parts intended for
mounting to the corresponding valve.
- Ease of access to installation site.
- Adequate clearance space above the thrust actuator for removing the hood
(refer to point 4.5 Dimensions).
- Install where there is protection against high-energy heat radiation.
- The ambient temperature must be between -20°C and +70°C.
If installed outdoors, the thrust actuator must be provided with an additional cover to protect
against
- rain,
- direct insulation,
- dust.
In case of widely fluctuating ambient temperatures, high atmospheric humidity and
temperatures below the freezing point, your are recommended to install a heating resistor
to minimise condensation buildup in the actuator.
- Thrust actuator mountable in any position except in downward suspended position.
If installed with a horizontal connecting rod, the thrust actuator must be mounted so both
yoke legs or columns are on top of one another in the vertical plane (see Fig. 4 ).
