A leak-tight 1 inch NPT sprinkler joint should be obtained by applying a minimum-to-maximum torque of 20 to 30 ft.-lbs. (26,8 to 40,2 Nm). 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 an Escutch- eon Plate by under or over-tightening the sprinkler. Re-adjust the position of the sprinkler fitting to suit.Step 1. Install pendent sprinklers only in the pendent position, and install upright sprinklers only in the upright position. The deflector of a pendent or upright sprin kler must be parallel to the ceiling.Install horizontal sidewall sprinklers in the horizontal position with their cen- terline of waterway perpen dicular to the back wall and parallel to the ceiling. Ensure the word “TOP” on the De flector faces the ceiling.Step 2. With a non-hardening pipe- thread sealant such as TEFLON tape applied to the Inlet threads, hand- tighten the sprinkler into the sprinkler fitting.
