Important Notes

Usage for the intended purpose

Use condensate drain valve AK 45 only for the discharge of condensed water in pipe lines or for air-venting within the admissible pressure/temperature ratings. Check the corrosion resistance and chemical suitability of the drain valve for the application in question.

For information on the application in potentially explosive areas see section “ATEX Directive 94/9/EC, 1999/92/EC” on page 5.

Safety note

The equipment must only be installed and commissioned by qualiﬁed staff. Maintenance and service work must only be performed by adequately trained persons who have a recognized level of competence.

Danger

The equipment is under pressure during operation. When loosening ﬂanged connections or sealing plugs, hot water and/or steam may escape.

This presents the risk of severe scalding. Installation and maintenance work should only be carried out when the system is

depressurized (0 bar): isolate the equipment from both upstream and downstream pressure.

The equipment becomes hot during operation. This presents the danger of severe burns to hands and arms. Installation and maintenance work should only be carried out when the system is cold.

Before carrying out any kind of maintenance work or undoing ﬂanged connections or sealing plugs make sure that all connected lines are depressurized (0 bar) and cooled down to room temperature.

Sharp edges on internal parts present a danger of cuts to hands. Always wear industrial gloves when replacing the regulator or the strainer.

Attention

The name plate indicates the technical speciﬁcation of the equipment. Do not commission or operate a steam trap without name plate.

Important Notes – continued –

PED (Pressure Equipment Directive)

The equipment fulﬁls the requirements of the Pressure Equipment Directive 97/23/EC. AK 45 can be used with ﬂuids of group 2. The equipment is not CE marked according to section 3.3 of the PED.

ATEX (Atmosphère Explosible)

The equipment does not have its own potential source of ignition and is therefore not subject to the ATEX Directive 94/9/EC. The equipment can be used in potentially explosive areas 0, 1, 2, 20, 21, 22 (1999/92/EC). The equipment is not Ex marked.
