3. If a submersible pressure gauge is attached to the first stage, ensure
that the gauge is facing away from you. Pressurise the regulator by
slowly opening the cylinder valve handwheel. Continue to turn the
cylinder valve handwheel until fully open, and then back
1
/
2 turn.
4. Listen near the first stage to check for any leakage. If leakage is
detected, immerse the first stage while pressurised to determine the
source.
5. If leakage has been detected, follow the procedure for removing
the regulator from the cylinder valve on page 29. If air was leaking
between the first stage and cylinder valve, replace or re-seat the
cylinder valve O-ring as needed and repeat the above procedure. If
leakage persists, return the cylinder and regulator to an authorised
dealer.
DIN to Yoke Converter
For regulators which may be used back and forth between Yoke and DIN
connections, Apeks offers a convenient DIN to Yoke converter. First, obtain
factory prescribed installation of the DIN connector through an authorised
dealer. Then, simply attach the converter to connect your regulator to a
yoke valve.
WARNING: Adaptors from yoke 1st stage to a DIN cylinder valve
must never be used. This would allow a greater working pressure
to be used than the yoke connector is designed to take.
