Make sure the drain pipe has a downward gradient (1/100 or more) and that there are no water
traps.
CAUTION
● Do not install an air bleeder as this may cause water to spray from the drain pipe
outlet.
Prohibited

(1) Drain hose connection
● The drain hose is connected below the refrigerant tubing.
CAUTION
● Wrap the drain insulator (supplied) between the connection of the drain hose and
tubing not to expose the copper tubing.
Also, wrap the hose band together.
Wrap the hose band with the drain insulator, where the screw is located facing
upward. Then, tighten the insulator with a vinyl tape not to cause the detachment.
If the tubing parts remain exposed, condensation may occur.
● Be sure to use the supplied drain hose.
● If other commercially available hose bands are used, the drain hose may become
pinched or wrinkled and there is danger of water leakage. Therefore be sure to use the
supplied hose bands.
● Connect the drain pipe so that it slopes downward from the unit to the outside.
● Never allow water traps to occur in the course of the piping.
● Insulate any piping inside the room to prevent dripping.
● After the drain piping, pour an appropriate amount of water into the drain pan through
the opening on the side of the air discharge port. Check the water draining smoothly.
