Task and function Purpose UNA 45 MAX, UNA 46 MAX and UNA 46A MAX are items of equipment for the steam process designed for the effective removal of condensate from steam. Equipment type UNA 45 MAX can also be used for removing condensate from compressed air systems.
Transporting the equipment Storing and transporting the equipment CAUTION Attention! Do not drop the equipment. If it falls down it may cause bruises and injuries. Equipment can be damaged if stored or transported improperly. To transport and mount the equipment safely use suitable lifting gear.
Mounting and connecting the DANGER equipment Personnel working on pipes are exposed to Preparing installation safety risks and may suffer severe injuries, poisoning or even loss of life. Take the equipment out of the transport packaging. Make sure that no hot or hazardous fluid is in the equipment or the pipes.
Orientation of the equipment Remove the adapter gasket (22). For the disposal of the adapter gasket observe The different equipment versions allow you to adjust the pertinent on-site regulations concerning the flow direction of the equipment to the flow waste disposal.
Replace all gaskets with new ones of the same Specialist personnel must be highly qualified and type. fully experienced in making pipe connections for the respective type of end connection. Turn the adapter (5) by 90° or 180° into the desired position of installation.
