Component Description
06-236115-001 3-31 October 2014
3-3.7.10 Supervisory Pressure Switch, P/N 06-118263-001
Note: The cylinder supervisory pressure switch can be installed on 600 lb through 900 lb ca-
pacity HFC-227ea cylinders with a 3" discharge valve manufactured prior to May 2013.
Any valve produced after May 2013 must use P/N 06-118262-001 Cylinder Supervisory
Pressure Switch.
The Supervisory Pressure Switch (P/N 06-118263-001) is intended to detect a fall in pressure
in the HFC-227ea cylinder (see Figure 3-36). The cylinder supervisory pressure switch can be
wired for either normally-open or normally-closed operation, depending on installation
requirements. The cylinder supervisory pressure switch can be installed on 600 lb through 900
lb capacity HFC-227ea cylinders with a 3 in discharge valve. If the pressure inside the cylinder
falls below 305 PSIG (21 bar gauge), the switch contacts will transfer and invoke a "trouble"
signal at the control panel.
