Installing Gas Drying Tumblers in
the European Union (EU)
General Information
This information is to be used when installing gas
tumblers in countries, and/or on gases, different than
the machine’s factory configuration. Tumblers are
supplied from the factory for operation on Natural Gas
or L.P. Gas in the countries of GB/IE/PT/ES/IT. To
install machines in any other country or on any other
gas requires some level of modification.
Orifices, stickers, block-open kits, regulator springs
and other parts needed for gas conversions are to be
ordered separately.
Models are built in three different configurations:
● Regulated Natural Gas – Injector is sized for
Natural Gas, second family, group H (E) at
20 mbar inlet pressure. Regulator/governor is
operational. Gas valve CAN be field converted to
a non-regulating type.
● Unregulated Natural Gas – Injector is sized for
Natural Gas, second family, group E+ at
20.25 mbar inlet pressure. Regulator/governor is
blocked open. Gas valve CANNOT be field-
converted to a regulating type.
● Unregulated L.P. (Liquified Petroleum) Gas –
Injector is sized for L.P. Gas, third family, group
3+ at 28.37 mbar inlet pressure. Regulator/
governor is blocked open. Gas valve CANNOT
be field-converted to a regulating type.
Serial plates supplied from the factory are configured
for the countries of GB/IE/PT/ES/IT. These
instructions pertain to the situations when the country
of use or gas supply is different than that on the serial
plate.
The tables describe the different gases that are
available in different EU countries, and how the
machines need to be configured to operate with those
gases. In the EU, there are Natural Gas configurations
that do not allow for machine regulation, and L.P. Gas
configurations that must be regulated. For L.P. Gas,
third family B/P at 50 mbar, order Regulated Natural
Gas machines and convert according to Table 2 or
Table 3.
WARNING
To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the
tumbler before servicing.
• Close gas shut-off valve to gas tumbler
before servicing.
• Close steam valve to steam tumbler
before servicing.
• Never start the tumbler with any guards/
panels removed.
• Whenever ground wires are removed
during servicing, these ground wires
must be reconnected to ensure that the
tumbler is properly grounded.
