(iii) Ensure the system flow control valve is closed then connect a hose
from a regulated high-pressure supply to the air inlet on the tester.
A high-pressure regulator and hose assembly, reference F3002, is
available for this purpose. Ensure the cylinder is fully charged by
reading the content gauge. (A partly discharged cylinder can give
an incorrect water test result.)
Note: Maximum inlet pressure at the tester is 10 bar.
