IMPORTANT INSTALLATION INFORMATION
•
DO NOT
install Style VS1 Dry Sprinklers that have been dropped or struck by
another object, even if they do not appear damaged. Never install glass bulb
sprinklers if the bulb is cracked or if there is a loss of liquid from the bulb. Discard
and replace any Style VS1 Dry Sprinklers that are damaged or show signs of
corrosion.
• Before installation, verify that the Style VS1 Dry Sprinkler is the proper style, orifice
size, and temperature rating for the intended service.
DO NOT paint, coat, or firestop the outlet portion
DO NOT paint, coat, or firestop the inlet portion
• DO NOT paint, coat, or firestop the outlet/inlet portion of the Style VS1 Dry
Sprinkler, identified in the above photo. Braided hose and fitting portions of
the Style VS1 Dry Sprinkler may be painted or coated, provided that the paint
or coating is compatible with stainless steel material. This includes penetration
through firestop-filled annular space of a firewall. The firestop material in direct
contact with the flexible braided hose will not impede functionality of the Style VS1
Dry Sprinkler, provided that the components are installed in accordance with the
installation instructions featured in this section.
• Style VS1 Dry Sprinklers that have been altered from their manufactured condition
may not function properly and may void agency listings and/or approvals.
•
DO NOT
test Style VS1 Dry Sprinklers with a heat source. The glass bulb can
weaken or shatter if exposed to a heat source during testing.
• Style VS1 Dry Sprinklers that have operated cannot be reassembled or reused, per
NFPA requirements. When replacing sprinklers, use new sprinklers of the same
type, orifice, temperature, and response.
• DO NOT clean Style VS1 Dry Sprinklers with soapy water, detergents, ammonia,
cleaning fluids, or other chemicals. Remove any dust, lint, etc. with a soft, dry
cloth.
• Inspect Style VS1 Dry Sprinklers on a regular basis for corrosion, mechanical
damage, obstructions, etc. The frequency of inspections may vary due to corrosive
atmospheres/water supplies and activities around the sprinklers.
• DO NOT hang anything from or attach anything to Style VS1 Dry Sprinklers.
Obstructing the discharge pattern will prevent the sprinkler from operating properly.
