recommended to rinse the regulator after each dive in fresh, warm water according to
the regulator’s manual.
Using any type of spray may result in damaging the plastic parts of the regulator.
Do not carry the cylinder holding the first stage. The cylinder’s handle serves this
function.
Chlorinated water may cause quicker wear of some components of breathing
apparatus.
Leaving the cylinder unprotected may result in its falling down and damaging the
valve or regulator’s first stage.
DIVING IN COLD WATER
European standard norms C.E.N. define cold water as 10°C or less. In such conditions,
especially in fresh water (higher temperature of freezing) there is danger of freezing the
pressure regulator or breathing apparatus. It can be most frequently observed by constant flow
of breathing gas from the breathing apparatus and consequently its sudden loss. The lower the
ambient temperature, the higher probability of such failure.
Demand regulators operating in low temperatures must be properly protected. The absolute
minimum is to isolate the water chamber in the pressure regulator from the environment by
non-freezing factor. In first stages of R 2 ICE, R 2 SPECIAL, R 5 ICE, R 5 TEC, V 2 ICE we
used the so called dry chamber, which significantly reduces the possibility of freezing during
the dive. It is advisable to use the above mentioned system in first stages used for dives in
deep water (below 30m).
To reduce the risk of freezing the demand regulator we should:
With the air temperatures close to 0°C and less avoid operating the regulator out of
water; avoid breathing or purging the regulator on the surface.
With the air temperatures close to 0°C and less stay as short as possible on the surface
before diving.
Avoid quick breathing.
Do not practice breathing in 2 persons from 1 demand regulator. In such situations it is
better to use additional, fully independent regulator.
DIVING IN DEEP WATER
It is worth remembering that diving in deep water enlarge the risk of decompression
sickness as well as other sicknesses. Diving below 40 m is generally not recommended.
Before attempting deep water diving you must receive training and certification from a
recognized certification agency and own proper to such type of dives equipment.
Demand regulators R 2 ICE, R 2 SPECIAL, R 5 ICE, R 5 TEC, V 2 ICE provide
unfailing operation up to the depth of 40m.
STORAGE
Do not store the regulator attached to the cylinder
The regulator should be kept in a clean, dry area where it will not be exposed to rough
handling, extreme heat, sun rays or chemical substances.
The regulator’s components should lay in a loose way, especially the hose, which
shouldn’t be bent or twisted.
The demand regulator should be protected from gasoline vapors, oils, alcohol and
other chemical substances.
