4-3.21.1 Installation of Pressure Switch 06-118262-001
Install the pressure switch as follows:
Note: Do not use with 3" valves manufactured prior to May 1, 2013.
1. Check that the sealing surface of the flare connection of the supervisory switch is not
scratched, dented, scored, etc.
2. Remove the end cap from the pressure switch port of the valve. This is a flare fitting and
does not require tape dope or any type of sealant.
3. Install the pressure switch onto the pressure port of the valve. Be sure to secure the pres-
sure port with a wrench so that you are not turning the port fitting further into the valve.
Tighten the switch hand-tight and then tighten 1/4-turn further using a wrench.
Important: Leak test the pressure switch connection with an HFC-227ea leak detector or
a bubbling solution. If the connection leaks, the switch may be tightened further until the
leak is eliminated, again, be sure to have a counter wrench on the switch port.
4-3.21.2 Installation of Pressure Switch 06-118263-001
Install the pressure switch as follows:
Note: For 3" valves manufactured prior to May 1, 2013 only.
1. Hold the pressure switch fitting on the valve with a wrench and remove the 1/8-inch plug
with a second wrench. Ensure that the fitting does not rotate in the valve body. The fitting
contains a check valve that will prevent the escape of the cylinder contents.
2. Before fitting the switch, apply Permacel® No. 412D Teflon® tape to the male threads of
the pressure switch.
3. Install the pressure switch into the port of the valve. Be sure to secure the pressure port
fitting with a wrench. Tighten the switch hand-tight and then tighten 1¼-turns further us-
ing a wrench.
Important: Leak test the pressure switch connection with an HFC-227ea leak detector or
a bubbling solution. If the connection leaks, the switch may be tightened further a 1/4-inch
turn at a time until the leak is eliminated, again, be sure to have a counter wrench on the
switch port. Do not exceed two turns from hand-tight. Refer to ANSI B1.20.3 for NPT thread
engagement details.
