Important Notes
Usage for the intended purpose
Use multi-capsule steam traps MK 25/2 and MK 25/2 S only for the discharge of
condensed water or for air venting from steam spaces.
Use this equipment only within the specified pressure and temperature ratings and
check corrosion resistance and chemical suitability for the application in question.
Danger
The steam trap is under pressure during operation.
When loosening flanged connections, plugs or the thermostatic capsule,
hot water and/or steam may escape. This presents the risk of severe burns
to the whole body.
Installation and maintenance work should only be carried out when the
system is depressurized: isolate the trap from both upstream and
downstream pressure.
The trap 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.
Sharp edges on internal parts present a danger of cuts to hands. Always
wear industrial gloves for installation and maintenance work.
Installation must only be performed by qualified staff.
Qualified staff are those persons who – through adequate training in engineering, the
use and application of equipment in accordance with regulations concerning steam
systems, and first aid & accident prevention – have achieved a recognised level of
competence appropriate to the installation and commissioning of this device.
