• Close the cylinder valve and check the pressure gauge once again. During the rst
minute the displayed pressure should not decrease. Then open the valve again.
• If the cylinder valve is equipped with a reserve rod, verify that it is free to move
downwards for its entire length. If you plan on using the reserve, ensure that the
mechanical reserve valve is in the correct position (Up).
• Check that the entire SCUBA unit is functioning correctly by performing several
complete breathing cycles (deep inhalation / exhalation) with the cylinder valve open and
the second stage mouthpiece in the mouth.
• Check that all devices connected to the SCUBA unit are operating correctly. For
example, check that the buoyancy compensator inator (or the dry suit inlet valve) is
functioning etc.
⚠
WARNING
Never connect a low pressure hose to a high pressure port. These connection
threads are different sizes and are not compatible. Do not use adapters of any
kind to connect low-pressure devices to high-pressure ports. Doing so could cause
serious damage to both the user and equipment.
⚠
WARNING
Check the integrity of the LP hoses before the dive, be sure there are no cuts,
swellings, cracks, discoloration or any other kind of damages on it. In such case
replace the hose before using.
⚠
WARNING
Check that the ends of the hose are correctly tightened to the SCUBAPRO rst and
second stage before starting the dive.
⚠
WARNING
LP HOSE: Maximum pressure 29bar. Do not exceed the pressure of 29 bar (420 psi).
Higher pressure may cause damages or personal injuries
7. EQUIPMENT USE
Check that the SCUBA unit is complete in all respects and complies with all requirements.
Refer to the IMPORTANT WARNING REMINDERS and PREPARING FOR USE sections. Open
the cylinder valve, don the equipment en put the second stage in your mouth, breathe deeply a
few times to ensure that the system is operating correctly. When the mouthpiece is out of the
mouth, simply pressing the purge button may trigger the Venturi effect and cause a regulator
free-ow. The free-ow can be stopped by covering the mouthpiece opening with a nger.
7.1 SecondstageswithVenturieffect(V.I.V.A.)adjustment
If the second stage is equipped with a Venturi effect adjustment system, this device must
be turned to the minimum (marked “MIN”) or the “PREDIVE” setting while at the surface
(Img. 6). At the beginning of the dive the adjustment knob must be turned to the “MAX” or
“DIVE” position.
An accidental free-ow can be stopped by covering the mouthpiece opening with a nger or
by submerging the second stage regulator with the mouthpiece turned down, or by placing
the mouthpiece in the mouth.
