INSTALLATION A. Installing the Model D-1 Sprinkler Guard: Model D-1 Sprinkler Guards can be retrofitted onto sprinklers that have already been installed on the system. However, it is recommended to install the guard onto the sprinkler prior to installing the sprinkler on the system and prior to applying any pipe -joint compound or tape to the external threads of the sprinkler. Consider ordering the guard factory installed on the sprinkler used. a. Loosen the screws in the brackets at the base of the sprinkler guard. b. Spread and hold the two bracket halves (at the base of the sprinkler guard) apart just enough to place the guard over the deflector and wrench boss of the sprinkler. c. With the sprinkler inside the sprinkler guard, position the guard so the two halves of the bracket grip the sprinkler just below the wrench boss, but above the threads. • Orient the sprinkler guard so the screw openings in the base of the guard are located at the ends of the sprinkler wrench boss (where the sprinkler frame arms contact the wrench boss). See Figure 1. d. Thread both screws into the openings provided in the opposite bracket half and tighten to secure the base of the guard to the sprinkler. e. Apply a small amount of pipe -joint compound or tape to the external threads only, taking care not to allow a build-up of compound in the sprinkler orifice. f. Install the sprinkler on the piping using the special sprinkler wrench. DO NOT use the guard to start or thread the sprinkler into the fitting. B. Installing the Dry Sprinkler Guard: Dry sprinklers must be installed on the system prior to in- stalling the guard onto the dry sprinklers. Note: When installing the Dry Sprinkler Guard on recessed Dry Pendent or recessed Vertical Dry Sidewall Sprinklers the Viking Recessed Escutcheon Cup Dry Sprinkler Guard (Order sprinkler guard separately from sprinklers.) The standard response dry pendent sprinkler with 5 mm glass bulb shown above is represen- tative only. The Dry Sprinkler Guard may be used with Viking standard or quick response dry upright, dry vertical sidewall, and dry pendent (including adjustable recessed) sprinklers. Figure 2 must be removed and the sprinkler centered in a minimum 2-1/8" (54 mm) diameter hole prior to installation of the Dry Sprinkler Guard. a. Remove the retaining ring from the Dry Sprinkler Guard. b. Spread and hold the two "C" shaped halves of the bracket (at the base of the guard) apart just enough to place the guard over the deflector and wrench boss of the sprinkler. c. With the sprinkler inside the guard, position the guard so the "C" shaped bracket halves of the guard grip the sprinkler in the slot provided just below the wrench boss. Orient the sprinkler guard so two of the four guard wires align with the frame arms of the sprinkler. See Figure 2. d. Push the retaining ring over the guard toward the base of the sprinkler until the ring snaps firmly into the depression provided on each of the four wire members of the guard. e. For recessed dry pendent or recessed vertical dry sidewall sprinklers, re -install the Viking recessed escutcheon cup. Form No. F_012798 21.04.29 Rev 21.1
