CORRECT INSTALLATION WRENCHES FOR USE WITH VIKING ESFR SPRINKLERS
ESFR sprinklers must be installed using the manufacturer's special installation wrench only, while taking care not to over-tighten
or damage the sprinkler operating parts. Figure 1 below shows an example of correct use of a designated ESFR sprinkler wrench.
Use of any other wrench, such as those shown in Figures 2 through 4 below, could damage the unit.
Viking ESFR Upright Sprinklers: Use Viking Wrench Part Number 05118CW/B.

Viking ESFR Pendent K14 and K16.8 Sprinklers: Use Viking Wrench Part Number 10285W/B or double-ended 13635W/B (Side A).

The sprinkler is contained in a plastic cap for protection during shipping and installation. With the sprinkler contained in the plastic cap,
apply a small amount of pipe-joint compound or tape to the male threads of the sprinkler and then install the ESFR sprinkler by applying
the wrench to the sprinkler wrench flats only. DO NOT use the deflector or fusible element to start or thread the sprinkler into a fitting.
Take care not to over-tighten the sprinkler and/or damage its operating parts!

chanical damage.

NOTE: The sprinklers are contained in plastic caps for protection during shipping and installation. Remove the caps from
the sprinklers AFTER installation. Use care when removing the caps to prevent dislodging the ejector spring or damaging
the fusible element. The caps MUST be removed from sprinklers BEFORE placing the system in service!
Refer to the latest appropriate technical data pages for complete care, handling, and installation instructions. Data pages are included with each
shipment from Viking or Viking distributors. They can also be found on the Viking Web site at www.vkinggroupinc.com.
Never install sprinklers that have been dropped, damaged, or exposed to temperatures in excess of the maximum ambient
temperature allowed. Any sprinkler with damage to the operating element should be destroyed.
