Issue Possible Causes
Troubleshooting
Unit does not turn
on when pressing
ON/OFF button
The unit changes from
COOL/HEAT mode to
FAN mode
The indoor unit
emits white mist
Both the indoor and
outdoor units emit
white mist
The indoor unit makes
noises
Both the indoor unit
and outdoor unit make
noises
The Unit has a 3-minute protection feature that prevents the unit from
overloading. The unit cannot be restarted within three minutes of being
turned off.
The unit may change its setting to prevent frost from forming on the unit.
Once the temperature increases, the unit will start operating in the
previously selected mode again.
The set temperature has been reached, at which point the unit turns off the
compressor. The unit will continue operating when the temperature
fluctuates again.
In humid regions, a large temperature difference between the room’s air
and the conditioned air can cause white mist.
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Low hissing sound during operation: This is normal and is caused by refrigerant
gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is
defrosting: This noise is normal and is caused by the refrigerant gas stopping or
changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts
caused by temperature changes during operation can cause squeaking noises.

Indoor Unit Installation
Installation Instructions – Indoor unit
PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the
label on the product box to make sure that the
model number of the indoor unit matches the
model number of the outdoor unit.
Step 1: Select installation location
Before installing the indoor unit, you must
choose an appropriate location. The following
are standards that will help you choose an
appropriate location for the unit.
Proper installation locations meet the
following standards:
Good air circulation
Convenient drainage
Noise from the unit will not disturb other
people
Firm and solid—the location will not vibrate
Strong enough to support the weight of the
unit
NOTE ABOUT WALL HOLE:
If there is no fixed refrigerant piping:
While choosing a location, be aware that you
should leave ample room for a wall hole (see
Drill wall hole for connective piping step)
for the signal cable and refrigerant piping
that connect the indoor and outdoor units.
The default position for all piping is the right
side of the indoor unit (while facing the unit).
However, the unit can accommodate piping to
both the left and right.
Refer to the following diagram to ensure
proper distance from walls and ceiling:
15cm (5.9in) or more
12cm (4.75in)
or more
2.3m (90.55in) or more
12cm (4.75in)
or more
Step 2: Attach mounting plate to wall
A location at least one meter from all other
electrical devices (e.g., TV, radio, computer)
DO NOT
install unit in the following
locations:
Near any source of heat, steam, or
combustible gas
Near flammable items such as curtains or
clothing
Near any obstacle that might block air
circulation
Near the doorway
In a location subject to direct sunlight
The mounting plate is the device on which you
will mount the indoor unit.
Remove the screw that attaches the mounting
plate to the back of the indoor unit.
Screw
Secure the mounting plate to the wall with
the screws provided. Make sure that mounting
plate is flat against the wall.
NOTE FOR CONCRETE OR BRICK WALLS:

Step 3: Drill wall hole for connective piping
Determine the location of the wall hole based
1.
on the position of the mounting plate. Refer
to Mounting Plate Dimensions.
2. Using a 65mm (2.5in) or 90mm(3.54in)
(depending on models )core drill, drill a
hole in the wall. Make sure that the hole
is drilled at
a slight downward angle, so
that the outdoor end of the hole is lower
than the indoor end by about 5mm to 7mm
(0.2-0.275in). This will ensure proper water
drainage.
3. Place the protective wall cuff in the hole. This
protects the edges of the hole and will help
seal it when you finish the installation process.

Step 4: Prepare refrigerant piping
Step 5: Connect drain hose
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.
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 following 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.
PLUG THE UNUSED DRAIN HOLE
NOT CORRECT
Do not place the end of the
drain hose in water or in
containers that collect water.
This will prevent proper
drainage.
To prevent unwanted leaks
you must plug the unused
drain hole with the rubber
plug provided.
