(1) Drainage pipe should have the same diameter or larger diameter than the connection
pipes (PVC pipe, outside diameter 17mm, thickness≥1.75mm).
(2) Keep drainage pipe short and sloping downwards at a gradient of at least 1% for
preventing forming air bubbles.
(3) Insert the drainage hose into drain socket, tighten the metal clamp securely.
(4) Warp the sealing pad over drain hose and metal clamp for heat insulation.
