NOTE: 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
1.18-1.95in(30-50mm), depending on the model.
Open and fix the position of the panel, then, open the covers of the two
lock blocks, unscrew the screw showed in the picture (Model A and
Model B), then hold both sides of the lower panel in the place marked
“PULL”, pull it upwards to release the buckles, then take the lower panel
down.
Use the holder at the back of the unit to prop up the unit, giving you
enough room to connect the refrigerant piping, and drain hose.
Connect drain hose and refrigerant piping (refer to Refrigerant Piping
Connection section of this manual for instructions).
Keep pipe connection point exposed to perform the leak test.
After the leak test, wrap the connection point with insulation tape.
Release the holder that is propping up the unit.
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.
Connect Drain Hose

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.
a. Wrap the connection point firmly with Teflon tape to ensure a
good seal and to prevent leaks.
b. For the portion of the drain hose that remains indoors, wrap it
with foam pipe insulation to prevent condensation.
c. Remove the air filter and pour a small amount of water into the
drain pan to ensure that water flows from the unit smoothly.
NOTE: Make sure to arrange the drain hose according to
illustrations in Figure 23.
