USE AND MAINTENANCE
!
WARNING
DO NOT attempt to use your regulator unless you have performed all of these pre-dive operating procedures. The LP
components are not designed for use with pressures higher than 285 psi.
Connecting the hoses to the first stage
The hoses and accessories should be connected in such a way as to avoid damaging the O-ring. Use a suitable wrench to remove the
plug from the first stage port, and screw the terminal fitting of the hose firmly but gently into the first stage port.
!
WARNING
The regulator in and of itself is not a complete SCUBA unit, but only one of its components.
Under the EN 250: 2000 standard, a complete SCUBA unit must include at least the following Minimum Equipment:
a) Air cylinder / cylinders.
b) Regulator.
c) Safety device, e.g. pressure gauge / computer or reserve or alarm.
d) Carrying frame or holding device, e.g. backpack and/or strap.
e) Facepiece (mouthpiece assembly or full face mask or diving helmet).
f) Operating instructions.
Your MARES regulator has been designed for use in conjunction with other SCUBA unit components conforming to
the EEC/89/686 directive and certified with the EC mark. The air inside the tanks must conform to the requirements for
breathable air set out in EN12021.
BEFORE ASSEMBLING THE COMPONENTS OF YOUR SCUBA UNIT, CAREFULLY READ ALL THE USER INSTRUCTIONS AND
ANY WARNINGS WHICH THEY CONTAIN.
PRE-DIVE CHECKLIST
- Ensure that all the hoses have been correctly assembled onto the 1st stage, and check them for cuts, signs of wear or other damage. If
the hoses are loose enough to be unscrewed manually, they must be tightened with a wrench before being pressurised.
- Make sure that the first and second stages do not show signs of damage.
- Position the tank control valve so that the valve opening is directed towards the diver.
- Remove the dust cap from the regulator yoke and position the A-clamp or DIN fitting so that it is centered on the tank valve opening.
- The first stage should be oriented in such a way that the hose leading to the second stage is routed over the diver’s shoulder (Fig. 2).
- Tighten the yoke nut finger tight only, being careful not to damage the O-Ring on the tank valve.
- Check the submersible pressure gauge, making sure that the pressure reading is zero.
- Very slowly open the tank valve, allowing air to enter the regulator gradually.
- Do not turn the first stage connected to the tank when the system is pressurized!!
!
WARNING
When opening the air valve, press the purge valve of the second stage. This helps to reduce the impact on the valve (Fig. 3).
DO NOT PERFORM THIS OPERATION AT AMBIENT TEMPERATURES BELOW 10°C (50°F).
- Check the pressure gauge to ensure that it indicates the proper cylinder pressure for your planned dive.
- Check the cylinder and regulator connection for leakage. If leakage exists, it may be caused by incorrectly mounting the regulator on the
valve or by a damaged cylinder valve O-ring.
- To confirm that the regulator delivers air properly, first exhale through the mouthpiece to blow any foreign matter from the second stage,
then inhale. A few breathing cycles should indicate if there are any obvious problems that cannot be discovered by actually breathing
from the regulator while underwater.
