Thank you for purchasing a Sealey Product. Manufactured to a high standard this product will,if used according to these instructions and properly
maintained, give you years of trouble free performance.
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS,
WARNINGS AND CAUTIONS. USE THIS PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS
INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE AND/OR PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY.
PLEASE KEEP INSTRUCTIONS SAFE FOR FUTURE USE.
1. SAFETY INSTRUCTIONS 2. INTRODUCTION & SPECIFICATION 2. introdu-
REG/MO.V2, REG/MT.V2
Read the following instructions carefully before using the regulator, and
keep them for future reference. The instructions provide all the
information necessary for correct use of the regulator, to avoid damage
and danger.
SEALEY will not be responsible for any damage occurring due to
incorrect use of the regulator, or to modifications made to it. This gas
regulator is a delicate piece of workshop equipment. Failure to observe
the following safety points will cause damage to the unit and will
invalidate your warranty.
Use regulator only for gas intended.
Use to designed pressure.
Check for damage and leaks at frequent intervals.
DO NOT knock or jolt regulator.
DO NOT use a regulator showing any signs of damage.
DO NOT allow cylinders to become heated.
DO NOT use pressure gauges that are damaged, not smooth in
operation or not zeroing.
DO NOT overtighten adjusting knob as this will damage diaphragm
and void warranty.
DO NOT oil the regulator.
WARNING! Incorrect use of the regulator can cause serious
damage. Users must be trained by specialist engineers.
WARNING! The regulator must be treated as a precision instrument.
Protect it from accidental knocks, dust, oil and other sources of dirt.
WARNING! Do not use the regulator if it is not in perfect working
condition
WARNING! When you draw gas, the cylinder must be placed upright
and protected from falling.
2.1 Top quality regulators made to EN ISO 2503, 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. Suitable for industrial size gas cylinders, these regulators are
designed only 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.

The function of the regulator is to reduce and control the pressure of a
gas. The regulator reduces the cylinder pressure at which the gas is
stored, to the pressure needed to use the gas.The pressure reducer 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 above ).
 WARNING!To try and use the pressure reducer with types of gasses
and pressures other than those indicated can be dangerous.

3. CONNECTION 5. STORAGE/MAINTENANCE
4. OPERATION
3.1 Connection of the regulator.
3.1.1 Check that the pressure 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 (3) anticlockwise to ensure that
the regulator valve is closed.
3.1.3 Replace the inlet connection gasket if it is damaged or lost.
3.1.4 Before screwing on the regulator, briefly open the cylinder
valve, then close it, in order to remove any impurity (only for
rechargeable bottles).
WARNING! During this operation it is dangerous to stand, or
place your hands in front of the cylinder valve.
3.1.5 Screw the regulator to the cylinder valve and tighten using a
suitable spanner. DO NOT over-tighten.
3.2 Hose connection.
3.2.1 Attach hose to the hose connection of the outlet connection (5)
and secure it with a hose clamp.
WARNING! Only use hoses complying with EN 559-ISO3821.
4.1 Gas supply.
CAUTION! Before opening the cylinder valve, check that the
regulator is completely closed (turn the pressure adjusting knob
(3) anticlockwise).
4.1.1 Slowly open the cylinder valve. The high pressure gauge (1) will
show you the cylinder pressure.
4.1.2 Opening the cylinder valve too quickly may make gauges
malfunction.
4.1.3 Turn the pressure adjusting knob (3) very slowly clockwise. The
low pressure gauge (2) will show the outlet pressure
(REG/MT only).
4.2 Regulate pressure.
4.2.1 To increase pressure: continue slowly turning the regulator
pressure adjusting knob (3) clockwise.
4.2.2 To decrease pressure: slowly turn the regulator pressure
adjusting knob (3) anticlockwise.
4.2.3 Using the pressure adjusting knob (3) it is possible to
compensate for eventual pressure drop within the cylinder.
CAUTION! Outlet pressure must not be regulated higher than
the pressure you need to use.
Outlet pressure must not be regulated higher than the red
mark on the low pressure gauge (2). (REG/MT only)
4.3 Closing
4.3.1 Close the cylinder valve.
4.3.2 Release the gas until the regulator gauges indicate "zero".
4.3.3 Turn the pressure adjusting knob (3) anticlockwise until it is
completely closed.
4.3.4 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 bottle seal.
Replacement of gauge.
Replacement of inlet connector.
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 return your regulator 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 close the cylinder valve immediately.
5.3.2 Unscrew immediately the regulator from the gas bottle0.
5.3.3 We suggest that the regulator be returned to the supplier to be
checked and repaired.
CAUTION! Do not use the regulator if there are the following
malfunctions:
The gasket (6) is damaged or lost.
The regulator or any of its parts (gauge, inlet connection, outlet
connection) are damaged or dirty, oily etc.
There are any leaky connections.
The relief valve adjustment has been modified or the valve
leaks.
5.4 Relief valve.(4)
5.4.1 Regulators are equipped with an excess pressure valve.
5.4.2 In case of malfunctioning, this valve allows the excess gas
pressure to escape.
CAUTION! Do 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 immidiately and have it
serviced by an authorised dealer.
