3-7. Installing the Drain Piping

(1) Prepare standard hard PVC pipe (O.D. 32 mm) for

the drain and use the supplied drain hose and hose

band to prevent water leaks. The PVC pipe must be

purchased separately. The unit’s transparent drain

port allows you to check drainage. (Fig. 3-26a)

(2) After checking the drainage, wrap the supplied

packing and drain pipe insulator around the pipe,

then secure it with the supplied clamps. (Fig. 3-26b)

Make sure the drain pipe has a downward gradient

(1/100 or more) and that there are no water traps.

NOTE

● Do not use adhesive at the drain connection

port on the indoor unit.

● Insert the drain pipe until it contacts the sock-

et, as shown in the figure at right, then secure

it tightly with the hose band.

● Tighten the hose clamps so their locking nuts

face upward. (Fig. 3-26a)

● Do not use the supplied drain hose bent at a 90°

angle. (The maximum permissible bend is 45°.)
