8. Dead set tolerance for regulator is 195 psi – 215 psi (13.44 bar
– 14.82 bar). Minimum flow is 140 psi (9.65 bar).
NOTICE
Before running the next test, secure the test kit
assembly to avoid whipping when pressure is
applied. During the test, the pressure reading
on the test gauge should not exceed the maxi-
mum dead set pressure rating for the model
regulator being tested. If the test gauge reading
exceeds the rated maximum,
immediately
open the control valve while quickly closing the
nitrogen cylinder valve. Such a reading indi-
cates a malfunction and the regulator must be
removed from service.
9.
Do not pull the Quick-Opening lever on cylinder valve as this
will not allow the pressure to slowly enter the test gauge.
Rapid introduction of pressure could cause damage to test
gauge.
Use the hand wheel to
slowly
open the nitrogen cylinder valve
while you observe the test gauge.
10. With the nitrogen cylinder valve fully open, observe the final
pressure on the test gauge for one minute. This reading must
be within the dead set range listed on the specification chart
(Page 16) for the model regulator being tested. If the reading
falls outside the specification, the regulator is malfunctioning
and must be removed from service.
Do not attempt to adjust
regulator.
11. Open the test kit control ball valve for 2 seconds while watch-
ing the test gauge. If the pressure falls below the minimum
flow requirements (140 psi (9.65 bar)), the regulator is mal-
functioning and must be removed from service. This test
should not exceed 3 seconds to conserve nitrogen.
12. Close the nitrogen cylinder valve. Open the control ball valve
to relieve the pressure in the regulator test assembly.
13. Disconnect the regulator tester from the test hose.
14. Disconnect the test hose from the quick-connect plug on the
tee from the regulator.
15. Remove the quick-connect plug from the tee on the regulator
outlet.
