2.1 Sealey Regulators are manufactured from only the highest quality
materials and machined almost entirely automatically to fine tolerances.
With correct use they will give reliable and trouble-free service. This
regulator is only suitable for use with the shielding gases Carbon Dioxide,
Argon or a mixture of these two gases (when used with the correct
adaptor). Do not use for any other purpose.

5. STORAGE/MAINTENANCE
The function of the regulator is to reduce and control the pressure of a gas. The regulator reduces the pressure at which the gas is stored, to the
pressure needed to use the gas.
The regulator has been designed so as to be used only and exclusively with the type of gas and at the pressure which are shown by the markings
stamped on the regulator body (refer to the markings key earlier in this section).
o o
WARNING! To try and use the regulator with types of gasses and pressures other than those indicated can be dangerous.
3.1 Connecting regulator.
3.1.1 Check that the regulator is correct both for the type of gas and
the pressure in the cylinder in use.
3.1.2 Turn the pressure adjusting knob anti-clockwise (REG/MMGT),
clockwise (REG/MM & REG/MMG) to check that the
regulator valve is closed.
3.1.3 Replace the inlet connection seal if it is damaged or lost.
3.1.4 Screw the regulator to the cylinder valve and tighten.
DO NOT over-tighten.
3.2 Hose connection.
3.2.1 Attach hose to the outlet connection of the regulator
by pushing it in as far as it will go.
o o
WARNING! Only use hoses complying with EN 559-ISO3821.
4.1 Regulate pressure.
4.1.1 To increase pressure and flow: slowly turn the regulator
pressure adjusting knob (5) clockwise (REG/MMGT) and
anticlockwise for the REG/MM & REG/MMG.
4.1.2 To decrease pressure and flow: slowly turn the regulator
pressure adjusting knob (5) anticlockwise (REG/MMGT) and
clockwise for REG/MM & REG/MMG.
4.1.3 Using the pressure adjusting knob (5) it is possible to
compensate for eventual pressure drop within the cylinder.
CAUTION!
oOutlet pressure must not be regulated higher than the pressure
you need to use.
4.2 Closing
4.2.1 Turn the pressure adjusting knob (5) anticlockwise until it is
completely closed.
4.2.2 Release the gas until the regulator gauges (if fitted) indicate
"zero".
4.2.3 Remove regulator from cylinder.
5.1 STORAGE.
5.1.1 The regulator must be treated as a precision instrument.
5.1.2 When the regulator is not to be used for long periods, store it
in its wrapping or in its box, to prevent contact with dust, oil
and other sources of dirt.
5.2 MAINTENANCE.
5.2.1 Do not carry out maintenance or repairs, other than the
following:
Replacement of inlet seal.
Replacement of guage.
5.2.2 Use only original spare parts and accessories.
5.2.3 Do not clean gauge glasses with petrol, solvents or any other
kind of detergent.
5.2.4 In case of failure take your regulator back to the retailer.
5.3 Malfunctioning.
5.3.1 In case of malfunction (e.g. leaks in the gauges or in the relief
valves) stop use and unscrew the regulator immediately from
the bottle.
5.3.2 We suggest that the regulator be returned to the supplier to be
checked and repaired.
CAUTION!
oDo not use the regulator if there are the following malfunctions:
oThe seal (1) is damaged or lost.
oThe regulator or any of its parts (gauge, inlet connection, outlet
connection) are damaged or dirty, oily etc.
oThere are any leaky connections.
oThe relief valve adjustment has been modified or the valve
leaks.
5.4 Relief valve.
5.4.1 REG/MMGT is equipped with an excess pressure valve.
5.4.2 In case of malfunctioning, this valve allows the excess gas
pressure to escape.
CAUTION!
oDo not modify the calibration of the relief valve.
5.5 Checking the seal
5.5.1 This check must be carried out only in the open air: use either
soapy water or a gas leak detector. Do not use flames.
5.5.2 Spray detector on the area to be checked.
5.5.3 The forming of bubbles or foam is a sign of a leak. If a leak is
detected remove regulator from service immediately and have
it serviced by an authorised dealer.
