Drain Piping Work
<<Rig the drain pipe as shown below and take measures against condensation. Improperly rigged piping could lead
to leaks and eventually wet furniture and belongings.>>
(1) Carry out the drain piping
• The diameter of the drain pipe should be greater than or equal to the diameter of the connecting pipe (vinyl tube ; pipe size
: 25 mm ; outer dimension : 32 mm).
• Keep the drain pipe short and sloping downwards at a gradient of at least 1 / 100 to prevent air pockets from forming.
• If the drain hose cannot be sufficiently set on a slope, execute the drain raising piping.
• To keep the drain hose from sagging, space hanging wires every 1 to 1.5 m.
CAUTION
Setting the unit at an angle opposite to the drain piping might cause leaks.
• Use the drain hose and the metal clamp. Tighten the clamp firmly. Insert the drain hose into the drain socket, up to the
tape. Tighten the clamp until the screw head is less than 4 mm from the hose.
• Wrap the sealing pad over the metal clamp and drain hose to insulate.
• Insulate the drain hose inside the building.
〈 PRECAUTIONS FOR DRAIN RAISING PIPING 〉
〈HOW TO INSTALL PIPING〉
(1) Connect the drain hose to the drain raising pipes, and insulate them.
(2) Connect the drain hose to the drain outlet on the indoor unit, and tighten it with the metal clamp.
(3) Insulate both metal clamp and drain hose with the sealing pad.
• If converging multiple drain pipes, install according to the procedure shown below.
Select converging drain pipes whose gauge is suitable for the operating capacity of the unit.
CAUTION
• Drain piping connections
Do not connect the drain piping directly to sewage pipes that smell of ammonia. The ammonia in the sewage might enter
the indoor unit through the drain pipes and corrode the heat exchanger.
• Keep in mind that it will become the cause of getting drain pipe blocked if water collects on drain pipe.
