WARNING:
DO NOT ATTACH A LOW PRESSURE HOSE TO A HIGH PRESSURE
PORT AND DO NOT USE ANY REDUCTIONS ON LP OR HP HOSES.
Properly arrange hoses supplying: BCD, dry suit, etc.
Inspect the demand regulator.
Inspect hose(s) and hose connections. See if the mouthpiece is properly mounted.
Test the under pressure tightness in the following way:
- Put the mouthpiece of first stage of breathing apparatus R 2 ICE, R 2
SPECIAL, R 5 ICE, R 5 TEC, V 2 ICE into the mouth;
- Shut the air inlet on the first stages of R 2 ICE, R 2 SPECIAL, R 5 ICE, R 5
TEC, V 2 ICE and take a breath through second stage of breathing apparatus
R 2 ICE, R 2 SPECIAL, R 5 ICE, R 5 TEC, V 2 ICE;
- Only if it is impossible to take a breath, the demand regulator is tight.
Before mounting the demand regulator to the cylinder blow through the valve of the
cylinder with air from inside the cylinder.
Make sure if the O-ring in cylinder valve is in good condition. If it is damaged or in
bad condition, it is necessary to replace it with a new one.
Hand tighten the demand regulator to the cylinder valve. DO NOT TIGHTEN IT TOO
STRONGLY.
Slowly open the cylinder valve – quick opening of the valve may result in shortening
of life of pressure regulator seat.
Check the functioning of demand regulator before diving:
- Listen carefully to all connections on demand regulator and check whether the
air is not coming out of it.
- Check whether the air supplying the regulator does not smell in an unpleasant
way.
- Press the purge on the second stage regulator and make sure the air flows
constantly until the purge is depressed.
- Take several breaths from the regulator second stage in the same time
observing the manometer or any other monitoring instrument. The indications
on the monitoring device should not change.
- Check the tightness in the water.
- Before submerging, put the mouthpiece of the breathing apparatus into the
mouth and make it tight with your teeth and mouth.

REQUIRED SAFETY DEVICES
Before diving the demand regulator should be equipped with a manometer or some
other device controlling the pressure inside the cylinder (for example a diving
computer).
The design of demand regulators R 2 ICE, R 2 SPECIAL, R 5 ICE, R 5 TEC, V 2 ICE
guarantees the user full safety during diving. It means that the breakdown of one of the
regulator’s components will not stop the flow of air to diver.
