Upright Type:
The upright type nozzle is installed upright on the water supply branch pipe. The shape of the sprinkling water is parabolic, and the water is sprayed down to 80~100% of the total water. At the same time, a part of the water is sprayed toward the ceiling. It is suitable for installation in places where there are many moving objects and easy to impact. For example, the warehouse can also be concealed in the roof of the ceiling of the room ceiling to protect the top of the ceiling with more flammable materials.
(When the ceiling is not to be used, when the water distribution pipe is arranged under the beam, the vertical type should be used. For the parts that are vulnerable to collision, the protective cover nozzle or the ceiling type nozzle should be used.

Pedent Type:
Pedent type nozzle is the most widely used type of nozzle, which is mounted on the water supply branch pipe. The shape of the water spray is parabolic, and 80-100% of the total water is sprayed to the ground. To protect a room with a ceiling, a nozzle should be placed under the ceiling, and a drooping or ceiling-type nozzle should be used.

Installation Precautions:
1) The nozzle installation should be carried out after the system pressure test and flushing certificate.
2) Special elbows and tees should be used when installing the nozzles.
3) When the head is installed, the head must not be disassembled or modified, and it is strictly forbidden to attach any decorative coating to the nozzle.
4) Special nozzles should be used for nozzle installation. It is strictly forbidden to use the frame of the nozzle to apply screw; when the frame of the nozzle, the splash tray is deformed or the original is damaged, the nozzle with the same specifications and model should be replaced.
5) When the diameter of the nozzle is less than 10mm, the filter should be on the main pipe of the curved water or the upper pipe of the manifold.
6) Installed on the nozzle that is vulnerable to mechanical damage, the nozzle should be installed.
7) When the nozzle is installed, the distance between the splash plate and the ceiling, door, window, hole or wall should meet the design requirements.
8) When the sprinkler disk of the sprinkler is higher than the bottom of the beam or the ventral surface of the ventilation pipe with the width less than 1.2m, the maximum vertical distance of the sprinkler disk above the beam bottom and the ventral surface of the ventilation pipe shall comply with the relevant standards.
9) When the width of the ventilation duct is greater than 1.2 m, the nozzle shall be installed below the ventral surface.
10) When the nozzle is installed near the partition near the top, the horizontal distance and the minimum vertical distance between the nozzle and the partition shall comply with the relevant regulations.
