IN CONFORMITY WITH ATEX DIRECTIVE
Products requiring approval are those that have their own potential ignition risk. These product categories include
moving parts. They are labelled with the CE marking and the explosion protection hexagon; operating instructions
and the EC declaration of conformity are provided.
These conditioning units of compressed air are envisaged for use in explosive atmospheres in the form of gas,
steam, mists and dust.
The classifi cation into zones 1-21 of these units is defi ned by the following markings: II2GD IIC T85°C (T6) X
or II2GD IIC T100°C (T5) X.
Compliance with essential health and safety requirements is guaranteed by conformity to the European Standard
EN 13463-1.
This specifi c ATEX documentation is supplied as an addition to the general user instructions where de-
tailed product information is provided.

Risk from electrostatic charges:
For the IIC Group, prevent electrostatic charging of external insulating surfaces by using the appropriate installa-
tion and cleaning measures. To clean external insulating surfaces use a damp cloth.
Connect the conditioning units to the earth.
When combined with other conditioning units, ensure that all metallic and conductive parts are always intercon-
nected and linked to the earth to avoid signifi cant electrostatic charges being created.
The earth is connected to the unit or to the combination of conditioning units by the downstream and upstream
use of metal pipes connected to the earth. If the pipes are non-conductive, earth connection should be performed
by the assembly and/or fi xing devices adapted to the ATEX products.

Installation, commissioning and servicing and maintenance
These operations may only be carried out by authorised personnel and in accordance with the usage instructions.
Only carry out maintenance in zones where there is no explosive atmosphere.
If during maintenance it is established that wearing and spare parts need exchanging, contact an ASCO NUMAT-
ICS reseller.
Any modifi cation of the product with parts not supplied by the manufacturer will invalidate the certifi cation.
Assembly of conditioning units
T T°C
The assembly comprises components which are individually certifi ed. Therefore assembly comprised in this way
does not generate any additional risk. Each component has a marking which is bespoke to that component and
the assembly category corresponds to the most unfavourable category of one of the components of the
85
assembly.

Product fi tted with a metal tank: FR and FRL (see fi g. A)
When replacing a fi lter element saturated by the FR (fi lter/regulator), proceed as described below:
85
• Loosen the screw (1)
100
• Remove the tank (2) from the body (3)
100 • Remove the fi lter element and replace with a new one
• Replace the tank (2)
• Tighten the screw (1) in the body (3) up to the contact of the tank and screw one quarter to a half turn extra
in order to ensure ground continuity.
For adding oil to the lubricator tank, proceed in the same manner as above.
