General connection instructions
• Use flexible, braid-reinforced hose piping or rigid piping.
• The system must not bear the weight of the pipes.
• Seal the piping well using appropriate products.
NOTE: The air cushion in the connection pipe may cause problems with flow and
blockage. To prevent any blockage, the inlet pipe should be purged at its highest
point.
Installing the lifting unit before putting the cover back on the frame facilitates the
installation and inspection of the connections.
