Notice To Owner/Installer
This unit is designed for easy installation by an experienced person. It is
legal for a homeowner to install it, however we highly recommend using
a licensed HVAC technician for installation.
Legal Information About Self-Installing R410A Air Conditioners
Can a homeowner install this system?
Yes, a homeowner with a vacuum pump, proper training, and equipment can install this unit. Unless
you are experienced with installing air conditioners we recommend you hire a professional installer. The
person who installs the system must do all work in compliance with local building and electrical codes.
Are there any restrictions on the purchase of R410A refrigerants?
R410a is not an ozone-depleting substance. At this time the purchase of R410a refrigerant is not restricted
in the US. There is no technician certification requirement for those that purchase HFC refrigerants, such
as R-410a or R-134a. If you are not licensed, some local HVAC supply companies may refuse to sell you
R410a based on a misunderstanding of the law, or because they wish to discourage homeowners from
working on their own systems.
Are there any restrictions on the use of R410A refrigerants?
Yes, it is illegal to knowingly vent or release these refrigerants. The venting prohibition applies to
R410a, and all other HFC refrigerants, just as it does for ozone-depleting refrigerants like R-22.
Is EPA technician certification required to service R410A systems?
No, at this time EPA technician certification is not required in order to service R-410a systems.

WARNING
1)
Engage a properly trained person for installation. If installation is defective, you may experience water
damage, electrical shock, or fire.
2)
Install according to these installation instructions. If installation is defective, you may experience water
damage, electrical shock, or fire.
3) Use the included accessories and specified parts for installation.
4) Select a proper location for the indoor and outdoor unit make sure the location can support the weight of the unit.
5) For electrical work, follow the local electrical codes and these installation instructions. Use a dedicated circuit.
If electrical circuit capacity or electrical work is not proper, it can cause electrical shock or fire.
6) Use the specified cable and connect tightly, clamping the cable so that the cable cannot come loose. A loose connection
may cause sparks, overheating, fire, or damage the system.
7) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board cover
is not fixed properly, it will cause heat-up at connection point of terminal causing fire or electrical shock.
8) When installing the refrigerant tubing connection, make sure not to let any substances other than the specified
refrigerant go into refrigeration tube. Otherwise, it may cause lower capacity, abnormally high pressure
in the refrigeration cycle, explosion, or injury.
9) Do not modify the length of the power supply cord or use of extension cord, and do not share the
circuit with other electrical appliances.
CAUTION
1)
This equipment must be grounded and should be installed with GFCI breaker. It may cause electrical
shock if grounding is not absolute.

INSTALLATION INSTRUCTIONS
Indoor unit installation
1. Fit the installation plate horizontally
on structural parts of the wall with
spaces around the installation plate.
2. If the wall is made of brick, concrete,
or the like, use #8 anchor screws of
the appropriate size.
3. Fit the installation plate on the wall
with eight (8) anchor screws.
Note:
Fit the installation plate and drill
holes in the wall according to the
wall structure and corresponding
mounting points on the installation
plate. The installation plate is different
according to the models.
(Dimensions are in "mm" unless
otherwise stated)
Drill a hole in the wall
1. Determine hole positions according
to the diagram detailed in Fig.5. Drill
one (1) hole (2 ½”) slanting slightly
to outdoor side.
2. Always use wall hole conduit when
drilling metal grid, metal plate, or the like.

INSTALLATION INSTRUCTIONS
Connective Tube and Drainage
Installation
1. Run the drain hose sloping downward.
Do not install the drain hose as
illustrated in Fig.7.
2. When connecting extension drain hose,
insulate the connecting part of extension
drain hose with a shield pipe, do not let
the drain hose slack.
Refrigerant Tube Installation
IMPORTANT:
The unit can only use right-hand piping
or right rear piping as shown in
Fig.8.
1. Remove the cover for right-hand piping first.
2. For the right rear piping, install the piping as
shown in fig. 8
3. Fix the end of the connective pipe. (Refer
to Tightening Connection in
REFRIGERANT PIPING CONNECTION)
Indoor unit installation
1. Pass the piping through the hole in the
wall.
2. Put the upper claw at the back of the
indoor unit on the upper hook of the
installation plate, move the indoor unit
from side to side to see that it is securely
hooked (see Fig.9 & Fig.10).
3. Piping can easily be made by lifting the
indoor unit with a cushioning material
between the indoor unit and the wall.
Remove material after it is not needed.
4. Push the lower part of the indoor unit up
on the wall, then move the indoor unit
from side to side, up and down to check
if it is hooked securely.
Do not block water flow by a rise.

INSTALLATION INSTRUCTIONS
Piping and wrapping
Bundle the tubing, connecting cable, and drain
hose with tape securely, evenly as shown in
Fig.11
Because the condensed water from rear of the
indoor unit is collected in the drain pan to be
piped out of room, do not put anything else in
the drain pan.
CAUTION
Connect the indoor unit first, then the
outdoor unit.
Do not allow the piping to drain out from the
back of the indoor unit.
Be careful not to let the drain hose slack.
Make sure to insulate the tubing.
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
overflow inside the unit.
Never wrap the power wire along with control
cable.
Run the drain hose sloped downward to
drain out the condensed water smoothly.
Outdoor Unit Installation
Install the outdoor unit on a rigid base to
prevent increasing noise level and vibration.
Determine the air outlet direction where the
discharged air is not blocked. In the case that
the installation site is exposed to strong wind,
make sure the fan is operating properly by
putting the unit lengthwise along the
wall or using a dust or shield plates.
Especially in windy area, install the unit to prevent the admission of wind. If using a suspending
installation, the installation bracket should
Follow the technique required in the
installation bracket diagram.
The installation wall should be solid brick,
concrete or the same intensity construction, or
actions to reinforce, damping supporting should
be taken. The connection between bracket and
wall, bracket and the air conditioner should be
firm, stable and reliable.
Be sure there are no obstacles which block air
flow.
