WARNING - TECHNICAL DATA SUBJECT TO EAR CONTROLS
THIS DOCUMENT CONTAINS TECHNICAL DATA WHOSE EXPORT IS RESTRICTED BY THE EXPORT ADMINISTRATION ACT OF 1979, AS AMENDED
(TITLE 50, U.S.C., APP. 2401, ET SEQ.) VIOLATION OF THIS EXPORT CONTROL LAW IS SUBJECT TO SEVERE CRIMINAL PENALTIES.
STORAGE
Store per ANSI-ASME N45.2.2 Level B
INSTALLATION
CAUTION:
The regulator must be installed with the
draincock downward to allow accumulated fluid to drain
out when the draincock is opened.
CAUTION:
Moisture and particulates can be
discharged at high speed when draincock is opened.
Teflon tape is the preferred thread sealant for the 1/4”
NPT connections.
WARNING
: If the supply line is connected to the “OUT”
port, regulator damage or unexpected flow through the
regulator could occur.
Prior to applying inlet pressure, double check the
connections and assure the wrench knob is backed out
sufficiently to unload the range spring in the bonnet.
Carefully apply inlet pressure and check the supply
connection for leakage. Adjust the output pressure by
rotating the wrench knob clockwise and check the outlet
connection for leakage.
WARNING:
The wrench knob can vibrate loose and fall
out if the jam nut is not tightened.

OPERATION IN SERVICE
Open upstream controls to provide the regulator supply
pressure. To increase the output set pressure, rotate the
knob clockwise. To decrease the output set pressure, rotate
the knob counterclockwise.
When the system is being shut down, it is an established
safety practice to reduce the output pressure completely,
then shut off the supply pressure to the regulator.
This will assure that no output pressure will be generated
when the supply pressure to the regulator resumes, the next
time the system is used.
