Use Of The Regulator In Cold Water; Care And Maintenance Of The Equipment; Caring For The Equipment - Cressi MC9 Manual De Istrucciones

WARNING: After assembling and checking it, the regula-
tor must be laid down horizontally, in order to prevent any
accidental fall from causing damage to its components or
injury to people.
3.4 – Use of the regulator in cold water
If your regulator is certified to be used in cold water (tempera-
tures < 10° C/50°F), Cressi sub recommend to follow carefully the
following advices in order to reduce the risk of freezing:
1. Protect the regulator from any accidental water in flow into
the first and second stages;
2. Protect the equipment from cold before diving, keeping it in
a warm dry place;
3. Avoid breathing through the regulator or pressing the discharge
button in freezing air before diving;
4. Avoid taking the mouthpiece out of your mouth when out of water
and while getting into water, in order not to let cold water seep
into the second stage;
5. As far as possible, avoid consuming a great amount of water
by diving (inflating gav, inflating surfacing or signalling buoy, shar-
ing air with another diver etc.);
6. Check the air contained in the tank satisfies the requisites pre-
scribed by EN 12021 standard and is free from excessive humidity.
WARNING: In case of dives in cold water (temperature
less than 10°C/50° F), Cressi-sub recommend to use a tank
supplied with a valve featuring two separate outlet ports, with
which two complete regulators are to be connected.
WARNING: diving in cold water at temperature lower than
10°C/50 °F requires a special technical training. Cressi-sub
recommend such diving only after attending a special training
course by certified trainers. Using underwater equipment in
cold water without adequate training may be dangerous for
the diver' s health and life.
The regulator must absolutely not get wet and exposed to
freezing air before use. Do not press the discharge button, par-
ticularly when the Venturi effect adjustment lever is on "dive". If
possible, keep the regulator in a warm place before use.
WARNING: SCUBA complying with EN 250:2000 stan-
dardmust not be used by more than a diver at the same time.
WARNING: in case SCUBA equipments are set and
usedby more than a diver at the same time, their breathing
performance in cold water might not satisfy the requisites pre-
scribedby EN 250:2000 standard.
3.5 – Care and maintenance of the equipment

3.5.1. - Caring for the equipment

After use, close the tank valve turning it clockwise fully. Press the
second stage manual supply button in order to let out all water
from hoses and connections.
Disassemble the first stage unscrewing the knob anticlockwise.
Protect the sintered filter with your finger while blowing off all
water and impurities from the protecting cap. Place now the lat-
ter on the first stage air inlet port and lock it with the knob, taking-
care the cap' s O-ring is in place as well.
After every use, we recommend to rinse the regulator in fresh
water while still pressurized: in this way, it is possible to wash the
whole second stage, preventing any impurity from reaching
theregulator, that might compromise its watertight capacity. Rinse
the first stage letting water flow also through the second stage's-
mouth piece and the exhaust tees, in order to take off any
impurity.
When rinsing the depressurized regulator, rinse the first stage
letting water flow also through the second stage' s mouthpiece
and the exhaust tees, in order to take off any impurity: be sure
not to press the manual supply button, in order to prevent water
from flowing into the hoses and inside the first stage.
Let the regulator dry in a cool aired place, placing the hoses in
such way as not to form acute angle folds.
