part of extension drain hose with a shield pipe, do not let the 

drain hose slack.

For the left-hand and right-hand piping, remove the pipe cover 

from the side panel.

For the right back and left back piping, install the piping as 

shown.

Bundle the tubing, connecting cable, and drain hose with tape 

securely, evenly as shown in Figure on the right.

Both sides drainage structure is standard. For both sides drainage 

structure, it can be choosen for right, left or both sides

drainage connection. If choosing both sides drainage connection, 

another proper drain hose is needed as there is only one drain hose 

offered by factory. If choosing one side drainage connection, make 

sure the drain hole on the other side is well plugged.

For 9k/12k models, if choosing left-hand or left-back piping,please 

choosing left side drainage connection. The connection of the

gathered in ponding box and is piped out of room. Do not put

anything else in the box.

CAUTION

Connect the indoor unit first, then the outdoor unit.

Do not allow the piping to let out from the back of the indoor unit.

Be careful not to let the drain hose slack.

Heat insulation should be done to the extension drain hose of 

indoor unit.

bundle. Locating at the upper side can cause drain pan to overflow 

inside the unit.

Never intercross nor intertwist the power wire with any other 

wiring.
