PRODUCT OVERVIEW
1) The installation of the nozzle should be carried out after the system pressure test and flushing are qualified.
2) Special elbows and tees should be used for nozzle installa-tion.
3) When installing the nozzle, it is not allowed to disassemble or modify it, and it is strictly prohibited to add any decorative coating to the nozzle to prevent the failure or sensitivity change of the tem-perature sensing element.
4) Special wrenches should be used for nozzle installation, and it is strictly prohibited to use the nozzle frame for tightening; When the frame and splash box of the nozzle deform or damage the re-leased components,a nozzle with the same specifications and model should be replaced.
5) When the nominal diameter of the nozzle is less than 10mm,a filter should be installed on the water distribution main or pipe.
6) Spray heads installed in areas prone to mechanical damage should be equipped with spray head protective covers.
7) When installing the nozzle,the distance between the splash box and the ceiling,door, window,opening or wall should meet the design requirements.
8) When the spray nozzle splash plate is higher than the nearby beam bottom or the ventral surface of the ventilation duct with a width less than 1.2m,the maximum vertical distance of the spray nozzle splash plate above the beam bottom and the ventral surface of the ventilation duct should comply with relevant standards.
9) When the width of the ventilation duct is greater than 1.2m,the nozzle should be installed below its belly surface.
10) When the nozzle is installed near a partition that does not reach the top,the horizontal distance and minimum vertical dis-tance between the nozzle and the partition should comply with rele-vant standards.
