General Instructions Do not install any bulb-type sprin- kler if the bulb is cracked or there is a loss of liquid from the bulb. With the sprinkler held horizontally, a small air bubble should be present. The diam- eter of the air bubble is approximately 1/16 in. (1,6 mm) for the 135°F (57°C) and 3/32 in. (2,4 mm) for the 286°F (141°C) temperature ratings.A leak-tight 1/2 in. NPT sprinkler joint should be obtained by applying a minimum to maximum torque of 7 to 14 lb-ft (9,5 to 19,0 N·m). Higher levels of torque can distort the sprinkler Inlet with consequent leakage or impairment of the sprinkler.Do not attempt to compensate for insufficient adjustment in the Escutch- eon Plate by under- or over-tightening the sprinkler. Re-adjust the position of the sprinkler fitting to suit.Step 2. With pipe-thread sealant applied to the pipe threads, hand- tighten the sprinkler into the sprinkler fitting.
