1. DESCRIPTION
Viking Freedom® Residential Concealed Horizontal Sidewall Lead Free
VK4800 is a small high-sensitivity solder link and lever residential sprinkler
designed for installation on concealed pipe systems, where the appearance of a
smooth wall is desired. The orifice design, with a K-Factor of 4.0 (57.7 metric
allows the sprinkler's efficient use of available water supplies for the hydraulically
designed fire-protection system. The operating element and special deflector
characteristics meet the challenges of residential sprinkler standards.
The sprinkler is hidden from view by a low profile, small diameter cover plate
installed flush to the wall. The cover plate is available in several decorative
finishes to meet design requirements. The two-piece design allows installation
and testing of the sprinkler prior to installation of the cover plate. After the system
has been tested and wall finish has been applied, the push-on design of the cover
plate assembly allows easy installation of the cover plate with up to 1/4" (6.4 mm)
adjustment. Sprinkler VK4800 is provided with a pipe guide to properly locate the
sprinkler and allow the 1/4" adjustment of the cover plate.
*
Lead content complies with the definition of 'Lead Free' established in the Reduction of Lead
in Drinking Water Act (S.3874) endorsed by AWWA's Water Utility Council, and California
Assembly Bill #1953.
