REFRIGERANT PIPING AND DRAINAGE
3.
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.
Knock-out Panel
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.
NOTE ON DRAIN HOSE
PLACEMENT
Make sure to arrange the drain hose
according to the following figures.
.
PLUG THE UNUSED DRAIN HOLE
To prevent unwanted leaks
you must plug the unused
drain hole with the rubber
plug provided.
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.
NOT CORRECT
Do not place the end of the
drain hose in water or in
containers that collect water.
This will prevent proper
drainage.
NOT CORRECT
Kinks in the drain hose
will create water traps.
Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating
sleeve attached to the back of the unit. 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 which
the piping will exit.
2. If wall hole is behind unit, keep the knock-out
panel in place. If the wall hole is to the side,
remove the plastic knock-out panel from that
side of the unit. This will create a slot through
which piping can exit. Use needle nose pliers if
necessary. There is a pre-cut Groove to assist.
The slot size is determined by pipe diameter.
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.
Step 5: Connect drain hose
By default, the drain hose is attached to the left
hand side of unit (when facing the back of the
unit). It may also be attached to the right-hand
side. To ensure proper drainage, attach the
drain hose on the same side that refrigerant
piping exits. 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 smoothly.
