Step 4: Prepare refrigerant piping The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare the piping before passing it through the hole in the wall. 1. Based on the position of the wall hole relative
to the mounting plate, choose the side from which the piping will exit the unit. 2. If the wall hole is behind the unit, keep the knock-out panel in place. If the wall hole is to the side of the indoor unit, remove the plastic knock-out panel from that side of the unit. This will create a slot through which your piping can exit the unit. Use needle nose pliers if the plastic panel is too difficult to remove by hand.
Knock-out Panel
3. If existing connective piping is already embedded in the wall, proceed directly to the Connect Drain Hose step. If there is no embedded piping, connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connection section of this manual for detailed instructions.
NOTE ON PIPING ANGLE Refrigerant piping can exit the indoor unit from four different angles:Left-hand side,Right-hand side, Left rear, Right rear.

Step 5: Connect drain hose
By default, the drain hose is attached to the lefthand side of unit (when you’re facing the back of the unit). However, it can also be attached to the right-hand side. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit. Attach drain hose extension (purchased separately) to the end of drain hose.
Wrap the connection point firmly with Teflon tape to ensure a good seal and to prevent leaks.
For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation. Remove the air filter and pour a small amount of water into the drain pan to make sure that water flows from the unit smoothly.
NOTE ON DRAIN HOSE PLACEMENT
Make sure to arrange the drain hose according to the follo.wing figures.

CORRECT
Make sure there are no kinks or dent in drain hose to ensure proper drainage.

NOT CORRECT
Kinks in the drain hose will create water traps.

CAUTION
Be extremely careful not to dent or damage the piping while bending them away from the unit. Any dents in the piping will affect the unit’s performance.

NOT CORRECT
Kinks in the drain hose will create water traps.

NOT CORRECT Do not place the end of the drain hose in water or in containers that collect water. This will prevent proper drainage.

PLUG THE UNUSED DRAIN HOLE

To prevent unwanted leaks you must plug the unused drain hole with the rubber plug provided.

Step 8: Mount indoor unit
If you installed new connective piping to the outdoor unit,do the following:
1. If you have already passed the refrigerant piping through the hole in the wall, proceed to Step 4.
2. Otherwise, double-check that the ends of the refrigerant pipes are sealed to prevent dirt or foreign materials from entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and signal wire through the hole in the wall.
4. Hook the top of the indoor unit on the upper hook of the mounting plate.
5. Check that unit is hooked firmly on mounting by applying slight pressure to the left and right-hand sides of the unit. The unit should not jiggle or shift.
6. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate.
7. Again, check that the unit is firmly mounted by applying slight pressure to the left and the right-hand sides of the unit.
If refrigerant piping is already embedded in the wall, do the following:
1. Hook the top of the indoor unit on the upper hook of the mounting plate.
2. Use a bracket or wedge to prop up the unit, giving you enough room to connect the refrigerant piping, signal cable, and drain hose.

3. Connect drain hose and refrigerant piping (refer to Refrigerant Piping Connection section of this manual for instructions).
4. Keep pipe connection point exposed to perform the leak test (refer to Electrical Checks and Leak Checks section of this manual).
5. After the leak test, wrap the connection point with insulation tape.
6. Remove the bracket or wedge that is propping up the unit.
7. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate.
UNIT IS ADJUSTABLE
Keep in mind that the hooks on the mounting plate are smaller than the holes on the back of the unit. If you find that you don’t have ample room to connect embedded pipes to the indoor unit, the unit can be adjusted left or right by about 30-50mm, depending on the model.
