(vi) Drain piping

1) Lay the drain piping with downgrade to facilitate flow of drain,and do not make a trap or chevron-shaped bend.

(The drain piping can be taken out from the unit to the left, right, rear and down direction.)

2) Wrap the thermal insulator on the hard vinyl chloride pipe (VP-16) laid in the room.
3) Run the drain piping in a place where there is no fear of abnormal odors being generated at the end of the drain hose.
4) Do not run the drain piping directly into a sewer where sulfur-based poisonous or flammable gases are generated.

There is danger of poisonous or flammable gases penetrating into the building through the drain piping.

5) Pour water into the drain pan below the heat exchanger to check that water is drained outdoors.
