STEP 2 - Connecting the Flow Switch to Pipe

Insert pipe threads into flow switch and turn 2
or 3 times until tight.
• Place one pipe wrench on hex fitting of flow

switch and one wrench on connecting piping.
Tighten to following torque values.
- 47 ft•lb (64 N•m) for 3/4” pipe
- 63 ft•lb (85 N•m) for 1” pipe

• Repeat to connect pipe to opposite side of

flow switch.

Apply pipe sealing compound or Teflon

tape to the

pipe threads.

NOTE:

Do not apply sealant to first threads as this

switch is grounded (earthed) via the pipe mounting.
