BRASS SWEAT FITTING TEES Location: The Waterflow Indicator should be located in a horizontal section of pipe where there is a straight run of at least 5 pipe diameters on FLOW each side of the Waterflow Indicator. Avoid: Locations adjacent to elbows, orifices and valves. D Mounting: The Waterflow Indicator must be MINIMUM MINIMUM 5 x D 5 x D installed vertically and upright as shown for horizontal locations only. 2 FLOW MM-623(A) 10/24/06 9:18 AM Page 4 INSTALLATION (cont'd) The Waterflow Indicator must be installed in the pipe using a threaded tee connection or welding fitting of minimum length such as a half coupling. Use a face or hex bushing to reduce the tee out- let if a reduced tee outlet thread size fitting is not available. ® a. Apply pipe sealing compound or Teflon tape to the Waterflow Indicator pipe threads. ® NOTE: Do not apply sealant to first threads as this Waterflow Teflon Indicator is grounded (earthed) via the pipe mounting. b. Attach the properly sized paddle. (See chart on page 2) Tighten the screw through the lock washer and paddle onto a. the paddle arm to 12-16 in•lb. (1.5-2 N•m) torque. Only one paddle is required for each pipe installation. Carefully bow 1 1 the paddle on 2 /2” NPT FS7-4F Series and 1 /4” NPT & 1 1 /2” NPT FS4-3F Series installations. FLOW c. Insert the Waterflow Indicator into the pipe tee. Turn the Waterflow Indicator two (2) or three (3) revolutions clockwise until tight. Do not put excessive force on cover when turning. Do not twist the housing to tighten into position. b. d. Place an adjustable wrench on Waterflow Indicator body to c. tighten to final position. Final position is with arrow on housing 9 aligned in the same direction as liquid flow. Approximately /16” of the thread will be turned into the tee +/- one turn. ACTUAL SIZE TEMPLATE FLOW Paddle d.

To remove the cover, loosen but do not 10 lb.•in(1.13 N•m). remove the two cover screws using the special tamper-proof wrench. b. Place the cover on the Waterflow Indicator sliding the slots behind the two loose cover screws. Push the cover down into the Waterflow Indicator. Electrical Conduit Connection Connect electrical conduit to Waterflow Indicator electrical enclosure. Follow accepted electrical practices when installing fittings and making connections. Refer to and follow local codes and standards when selecting the types of electrical fittings and conduit to connect to Waterflow Indicator.
