Description
Horizontal Sidewall Sprinklers
HD Horizontal Sidewall Sprinklers are designed for use in light and ordinary hazards for standard installation. The design provides a crescent-shaped water discharge pattern for installation along a wall or side of a beam and just beneath a smooth ceiling. The temperature response type is standard response
(5mm glass bulb) and quick response (3mm glass bulb). The fast response type glass bulb and the special deflector combine speed of operation and area of coverage making it an ideal choice for standard coverage applications while being aesthetically pleasing. Chrome plating gives the sprinkler a good corrosion resistance in most types of corrosive environments.
Sprinkler Operation
The Sprinkler operating device is state of the art heat responsive frangible glass bulb supplied by a world leader in this innovative technology. The glass
bulb contains fluid which expands when exposed to heat. When rated temperature is reached, the bulb shatters and water flows through the sprinkler and strikes deflector, forming an uniform water spray pattern to control or extinguish fire. Style Horizontal Sidewall Sprinklers

Care and Handling
Sprinklers must be handled with due care, they must be stored at ambient temperature for best results. Storage as well as any onward shipment is to be made in original packing only. Sprinklers must be visually inspected carefully before installation. Sprinklers visibly damaged, dropped or exposed to temperature in excess of the maximum ambient temperature permitted, should never be installed. Never install any glass bulb sprinkler if the bulb is cracked or if there is a loss of liquid from the Bulb.
Sprinklers must be installed after the piping is in place, to prevent mechanical damage. Use Teflon tape or soft thread sealant on male thread
of the sprinkler for leak tight sprinkler joint. Use proper wrench. Use appropriate torque. Excessive tightening torque may distort the sprinkler inlet and
cause leakage. Sprinklers must never be painted, plated or coated after they leave factory.
The HD sprinkler described herein must be installed and maintained in accordance with the latest edition of HD technical data, the latest standards of the National Fire Protection Association (NFPA) and Factory Mutual (FM) or to the standard of any other authorities having jurisdiction. The owner is solely responsible for maintaining their fire protection system and devices in proper operating condition.

INSPECTION TESTING AND
MAINTENANCE
Refer to NFPA 25 for inspection, testing and maintenance requirement or to the authority having jurisdiction. For detail of warranty refer HD’s current
conditions of sale or contact HD Sales directly. Exposure to ultraviolet or direct sunlight for extended period may cause the liquid dye in glass bulb to fade or lose colour. Colourless or faded bulbs are not a problem, as long as the fluid level has not been affected. The loss of colour in the liquid will not affect sprinkler performance, as long as the bulb is intact and not damaged. The loss of colour may be an issue in identifying sprinkler temperature rating, but the temperature rating is still stamped on the sprinkler deflector
