3.1 Description of function
The elbow tube strainer is used to filter solid matter in liquids. When the liquid flows through the
strainer in the direction of the arrow (see figure), the solid matter is retained in the mesh bottom.
3.2 Installation Instructions
Fitting position
• The installation position is without importance.
CAUTION
Steps should be taken to ensure that no external forces are exerted on the fitting.
3.3 General welding guidelines
Sealing elements integrated in weld components must generally be removed prior to welding. To
prevent damage, welding should be undertaken by certified personnel (EN ISO 9606-1). Use the TIG
(Tungsten Inert Gas) welding process.
CAUTION
Damage and injuries due to high temperature supply
To avoid a distortion of the components, all welding parts must be welded to stress-relieved.
Allow all components to cool before assembling.
NOTICE
Damage due to impurities
Impurities can cause damage to the seals and seals area.
Clean inside areas prior to assembly.
