REGULATOR TEST
With the agent storage tank properly isolated, proper test kit
connected, and fully-charged nitrogen cylinders installed, test the
pressure regulators by completing the following steps:
NOTICE
If test gauge reading exceeds maximum regu-
lator pressure (Table 1) when nitrogen cylinder
valve is opened, immediately open test kit
control valve and close nitrogen cylinder valve.
Gauge readings in excess of maximum regula-
tor pressure indicate a malfunctioning
regulator.
1. Make certain test kit valve is closed.
2. Using handwheel, slowly open nitrogen cylinder valve while
observing test gauge.
NOTICE
For systems equipped with dual regulators,
each nitrogen cylinder is supplying pres-
sure to two regulators. Therefore, both
regulators are being tested simultaneously.
3. With nitrogen cylinder valve fully open for one minute, observe
test gauge pressure. The test kit gauge must read as follows:
Acceptable Pressure Range
Regulator Minimum Maximum
Model Part No. psi (bar) psi (bar)
________ _______ _________ _________
Rego 14796/14797 210 (14.5) 230 (15.9)
Rego 14798 210 (14.5) 230 (15.9)
Rego 19821 or 65 (4.5) 85 (5.9)
(Subsurface) 16123/16124
Victor 24232 195 (13.5) 215 (14.8)
Victor 472014 120 (8.3) 130 (9.0)
TABLE 1
4. Observe test kit gauge while opening test kit valve for 2 – 3
seconds. (In order to conserve nitrogen, this test should not
exceed 3 seconds.) The test kit gauge must read as follows:
Minimum Required
Regulator Flow Pressure
Model Part No. psi (bar)
________ _______ ________________
Rego 14796/14797 140 (9.7)
Rego 14798 140 (9.7)
Rego 19821 or 45 (3.1)
(Subsurface) 16123/16124
Victor 24232 140 (9.7)
Victor 472014 90 (6.2)
TABLE 2
5. Close nitrogen cylinder valve and open test kit valve to relieve
remaining pressure.
6. Repeat Steps 1 through 5 for each nitrogen cylinder and
corresponding regulator(s).
7. Disconnect test kit and quick-connect hose from quick-
connect plug. Remove quick-connect plug from regulator
outlet.
When reinstalling safety relief valves into Victor regulators,
turn only inside hex (nearest regulator body). Do not turn
outside hex as pressure relief setting could change.
8. Reinstall pressure relief valve into regulator outlet. Wrench
tighten snugly; do not overtighten. (With Rego regulators,
make certain relief valve gasket is in place.)
9. Systems with One Regulator per Nitrogen Cylinder:
Replace any regulators that are malfunctioning.
Systems with Two Regulators per Nitrogen Cylinder: If
initial test indicates that one or both regulators in a pair may
be malfunctioning, each regulator in that pair must be tested
individually. Complete test on Page 4 for individual testing of
dual regulators.
10. Return system to normal operating condition by performing
Post-Test Procedures on Page 5.
