Drainpipe and drain hose installation
Care must be taken when installing the drainpipe and drain hose for the
indoor unit so that condensate water is drained correctly outside.
1
Fix the flexible hose to the drainpipe.
The connection port of the flexible hose and PVC drainpipe must be fixed
with PVC adhesives.
Check out that the connected part doesn’t leak.
2
Connect the flexible hose to the flexible hose port.
Make sure that a rubber ring is installed on the drain hose port.
3
Install the drainpipe as shortly as possible.
Give a slightly slant to the drainpipe for proper drainage of condensate
water.
There must be no gap on the connected part so that the drainpipe is not
separated from the flexible hose .
4
Insulate the drainpipe, and then fix it as indicated.
