CAUTION ON ENVIRONMENTAL INSTALLATION CONDITIONS
4.INSTALLATION
4-1 Installation
Caution on indoor installation
* The actuators are not of explosion-proof type. Do not install in a hazardous place.
* Cover whole the unit, if it is installed at a place where water or materials are splashing.
* Reserve a space for manual maintenance work.
Caution on outdoor installation
* Shade the unit from direct sunlight, that may cause overheat and defect to the unit.
* Reserve a space for manual maintenance work.

4-2 AMBIENT TEMPERATURE / FLUID TEMPERATURE
Ambient temperature
* Environmental temperature range for use : –25℃〜55℃.
* For use in minus temperature, in-fit space-heater is available at option.
* For use in temperature beyond the specified range, refer to our Sales Dept.
Fluid temperature
It is occasional that if the actuator is applied to a high temperature fluid line, the unit mayoverheat
by transmission of line heat. In such a case, use radiation type bracket and couplings. (available at
option)
* Standard bracket and couplings : Fluid temperature max. 65℃
* Radiation type bracket and couplings : Fluid temperature over 65℃
