4. Connective Pipe and Drainage Installation
Drainage
• Run the drain hose sloping downward. Do not install the drain hose as
illustrated in the "wrong" gures in Figure 8.
• When connecting extension drain hose, insulate the connecting part of
extension drain hose with a shield pipe. Do not let the drain hose slack.
Installation of Connective Pipe
• For the left-handed and right-handed piping, remove the pipe cover
from the side panel.
• For the right back and left back piping, install the piping as shown in
Fig. 9 and Fig. 10.
NOTE: One side drainage structure is standard. Both sides drainage
structure is optional and can only be customized from factory. For both
sides drainage structure, it can be chosen 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 right side drainage connection, please
choose right-hand or right-back piping. The connection of the drain hose
is supposed to be done by a qualied installer in case of water leakage.
• Bundle the tubing, connecting cable, and drain hose with tape securely
and evenly as shown in the gures on the right.
NOTE: Because the condensed water from rear of the indoor unit
is gathered in the drain pan and is piped out of the room, do not put
anything else in the drain pan.
CAUTION
• Connect the indoor unit rst, then the outdoor unit.
• Be careful not to let the drain hose slack.
• Heat insulation should be done to the extension drain hose of indoor unit.
• Be sure that the drain hose is located at the lowest side of the bundle.
Locating at the upper side can cause drain pan to overow inside the unit.
• Never inter-cross nor inter-twist the power wire with any other wiring.
• Both the liquid and suction refrigerant lines must be insulated.
Indoor Unit Installation
• Pass the piping through the hole in the wall.
• Hook the indoor unit onto the upper portion of installation plate.
(Engage the indoor unit with the upper edge of the installation plate.)
Ensure the hooks are properly seated on the installation plate by
moving it in left and right.
• Piping connections can be easily made by lifting the indoor unit with a
cushioning material between the indoor unit and the wall. Remove after
nished piping.
• Press the lower left and right side of the unit against the installation
plate until hooks engage with the slots.
