• Do not apply adhesive between the drain hose connection and the drain hose.
• Do not apply too much force when making the drain hose connection as this could damage it.
• Do not use bent or twisted drain pipes as these will cause water leaks.
Then insulate the drain hose appropriately.

If there is excessive clearance between the drain pipe connection and the drain hose, add a sealing material between both parts in order
to fit and not deform the drain hose.
