1. FUNCTION AND INTENDED USE
- The function of the pressure reducer is to reduce and
stabilize the pressure of a gas; the reducer changes the
pressure at which the gas is kept in the cylinder into the
pressure needed to use the gas.
- This pressure reducer must be used solely for aquari-
ums sector. It is intended for the domestic market and
must only be used by qualified personnel.
- The pressure reducer has been designed so as to be
used only and exclusively with gas CO
sure which are shown by the marking.

- To try and use the pressure reducer with types of gasses
and pressures other than those indicated can be dan-
gerous.
CAUTIONS
• Incorrect use of the pressure reducer can cause se-
rious damage. Users must be trained by specialist
engineers.
• The pressure reducer must be treated as a precision
instrument. Protect it from accidental knocks, dust,
oil and other sources of dirt.
• Do not use the pressure reducer if it is not in perfect
working condition (see 5.1).
• When you draw gas, the cylinder must be placed up-
right and protected from falling.
• Do not expose the pressure reducer to direct sunlight
and/or bad weather.
• Do not smoke near the pressure vessel.
• Keep out of reach of children.
2. INSTALLATION
2.1 Connection of the pressure reducer
- Check the conditions of the pressure reducer before
use.
- Check that the pressure reducer is correct both for the
type of gas and the pressure in the cylinder in use.
- Turn the pressure adjusting handle (6) toward the - sym-
bol, to check that the pressure reducer valve is closed.
- Minimum cannot be regulated because of a fixed set-
ting.
- Replace the gasket (2) if it is damaged or lost and any
time you change the cylinder using a suitable tool.
- Make sure that the cylinder valve is not damaged. If it
is damaged, do not screw in the reducer and contact
the reseller.
- Before screwing in the pressure reducer, briefly open
and close the cylinder valve (1) to remove any impuri-
ties, using compressed air if necessary.
- Pay attention to turn the cylinder valve (1) toward the
wall and to carry out the operation away from heat
sources.
- During this operation it is dangerous to stand, or place
your hands in front of the cylinder valve (1).
- Connect the Inlet connection (3a/3b) to the cylinder
valce, if necessary clamping it using a suitable tool (not
tweezers) .
- Assemble the reducer so that the pressure gauge dials
can be read by the operator.
- If an hexagonal nut is present use the wrench of the
right dimension (do not use tools that could damage
the connection.
- If there is a knurled nut carry out the tightening ma-
nually.
, and at the pres-

- If the cylinder accidentally falls, check the conditions
of both the reducer and of the vessel, contacting the
