•Assemble the regulator and fittings in the orientation shown below. All
fittings should be tightly fastened. Use brown threadsealant (PN 445091) on
all mating threads. Brown threadsealant has a 24 hour cure time and
should be fully cured before supplying pressure through the fittings.
•Using brown threadsealant,
install the set screw
provided with SF239 as
shown (left).
•Rotate the valve on SF252
counterclockwise until it is
all the way “Closed”.
•Screw the SF225 pressure
tank into SF252.
•Note: DO NOT open valve
until threadsealant has
cured.
•Once brown threadsealant
has cured, turn valve SF252
clockwise until it is all the
way open and set SF239
regulator to 60 psi.
