Drain hose connection
The correct position for the drain hose connection is shown below.
Prepare a polyvinyl chloride (PVC) pipe with an outer diameter of
26mm.
The drain hose must have a gradient of 1% (1/100) to 4% (1/25).
The drain hose cannot be installed on an upwards line, not even on
one section of the installation. In this case, the condensate water
accumulates at the lowest point immediately before the raised
section of the installation.
Seal the connection using waterproof chloride sealing material.
Insulate the connection part carefully.
Secure the drain pipe to the connection part using the clamp
supplied.

• 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.
Insulate the drain pipe and suspend it individually as indicated in the figure.

C A U T I O N
• Do not apply adhesive between the drain hose connection and the drain hose.
• Do not install the condensate discharge pipe next to the gas refrigerant pipes. Any accumulated water could freeze and block the
discharge system.
