valve and tighten the handwheel by hand until it is lightly snug.
DO NOT use tools to tighten.
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 24. 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.
