AUTOMATIC SPRINKLER HEAD

Pendent and upright and conventional and sidewall sprinklers are designed for use in automatic sprinkler
systems designed in accordance with standard installation (NFPA13). The temperature response is standard
response 5mm glass bulb and fast response 3mm glass bulb. The sprinklers come with compact design
available in different finishes and temperature ratings.
The sprinklers body is made of brass die-casting copper alloy (DZR). The spring seat consists of a spring
Belleville washer coated on both side with a Teflon tape.
Pendent and conventional and sidewall sprinklers are installed with adjustable or non-adjustable escutcheon
plates. These are intended to be installed finished ceilings. Escutcheon plate adjustment provides convenience
in pendent and conventional sprinkler installation in case of areas with finished ceiling or walls.

The sprinklers which are manufactured and tested in accordance with the rigid requirements of the Standard
UL 199, also should be installed in accordance with the current Standard NFPA13. The system piping must be
properly sized to insure the minimum required flow rate at the sprinkler. Check for the proper model, style,
orifice size and temperature rating prior to installation, install sprinkler after the piping is in place to avoid
mechanical damage, replace any damage units, wet pipe systems must be protected from freezing.
Upon completion of the installation, the system must be tested per recognized standard. In case of a thread
leak, remove the unit, apply new pipe joint compound or tape and re-install.

1. Pendent sprinkler must be mounted in a pendent position, and upright sprinkler must be mounted in
   upright position, the C U/P sprinkler may be mounted both in upright and pendent position, the horizontal
   sidewall sprinkler is install at horizontal position, to suit for field condition.
2. Hand tighten the sprinkler into the sprinkler fitting. It is recommended that a torque of 7 ~14 ft lbs be used
   to obtain a thread 1/2 inch NPT Sprinkler joint. A radial force of 10 – 20 lbs.
3. For using only a non-hardening pipe joint compound or Teflon tape apply to the male thread only.
4. Hand tighten the sprinkler into fitting, use a 22mm open spanner or 8” (200mm) adjustable wrench on flat
   to tighten the unit into the fitting, do not use spanner on the frame arms, for it will cause the arms break
   and efass bulb burst.
