ENGLISH
IMPORTANT!
Please read this instruction sheet completely before installing the product.
This air conditioning system meets strict safety and operating standards. As the installer or service person,
it is an important part of your job to install or service the system so it operates safely and efficiently.
CAUTION : Improper installation, adjustment, alteration, service or maintenance can void the warranty.
The weight of the condensing unit requires caution and proper handling procedures when lifting
or moving to avoid personal injury. Use care to avoid contact with sharp or pointed edges.
Safety Precautions
• Always wear safety eye wear and work gloves when installing equipment.
• Never assume electrical power is disconnected. Check with meter and equipment.
• Keep hands out of fan areas when power is connected to equipment.
• R-410A causes frostbite burns.
• R-410A is toxic when burned.
NOTE TO INSTALLING DEALER: The Owners Instructions and Warranty are to be given to the owner
or prominently displayed near the indoor Furnace/Air Handler Unit.
When wiring:
Electrical shock can cause severe personal injury or death. Only a qualified,
experienced electrician should attempt to wire this system.
• Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked.
• Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
When transporting:
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and
bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on
the air conditioner can cut your finger.
When installing...
... in a wall: Make sure the wall is strong enough to hold the unit's weight.
It may be necessary to construct a strong wood or metal frame to provide added support.
... in a room: Properly insulate any tubing run inside a room to prevent "sweating" that can cause
dripping and water damage to wall and floors.
... in moist or uneven locatinons: Use a raised concrete pad or concrete blocks provide a solid,
level foundation for the outdoor unit. This prevents water damage and abnormal vibration.
... in an area with high winds: Securely anchor the outdoor unit down with bolts and a metal
frame. Provide a suitable air baffle.
... in a snowy area(for Heat Pump Model): Install the outdoor unit on a raised platform that is
higher than drifting snow. Provide snow vents.
When connecting refrigerant tubing
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Check carefully for leaks before starting the test run.
When servicing
• Turn the power OFF at the main power box(mains) before opening the unit to check or repair
electrical parts and wiring.
• Keep your fingers and clothing away from any moving parts.
• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have
been left inside the unit being serviced.
WARNING
WARNING
•
• Refer to local code for all wiring size.
Installation or repairs made by unqualified persons can result in hazards to you and others.
Installation MUST conform with local building codes or, in the absence of local codes, with the National Electrical
Code NFPA 70/ANSI C1-1993 or current edition and Canadian Electrical Code Part1 CSA C.22.1.
• The information contained in the manual is intended for use by a qualified service technician familiar with safety
procedures and equipped with the proper tools and test instruments.
• Failure to carefully read and follow all instructions in this manual can result in equipment malfunction, property
damage, personal injury and/or death.

Outdoor unit
1. If an awning is built over the unit to prevent
direct sunlight or rain exposure, make sure
that heat radiation from the condenser is not
restricted.
2. Ensure that the space around the back and
sides is more than 30cm(11.8in). The front of
the unit should have more than 70cm(27.6in)
of space.
3. Do not place animals and plants in the path
of the warm air.
4. Take the air conditioner weight into account
and select a place where noise and vibration
are minimum.
5. Select a place so that the warm air and noise
from the air conditioner do not disturb
neighbors.
Rooftop Installations
If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the roof structure
and anchoring method are adequate for the unit location. Consult local codes regarding rooftop
mounting.
If the outdoor unit is installed on roof structures or walls, this may result in excessive noise and
vibration, and may be also classed as non serviceable installation.
Indoor unit
1. Do not have any heat or steam near the unit.
2. Select a place where there are no obstacles
in front of the unit.
3. Make sure that condensation drainage can
be conveniently routed away.
4. Do not install near a doorway.
5. Ensure that the space around the left and
right of the unit is more than 30cm(11.8in).
The unit should be installed as high on the
wall as possible, allowing a minimum of
20cm(7.9in) from ceiling.
6. Use a stud finder to locate studs to prevent
unnecessary damage to the wall.
Select The Best Location
Install the indoor unit on the wall where the height from the floors more than 1.5meters(4.9ft).
A minimum pipe run of 7.5meters(24.6ft) is required to minimize vibration and excessive noise.

How To Mount Installation Plate
• Drill the piping hole with a ø65mm(2.55in)

the right or the left with the hole slightly
slanted to the outdoor side.
Drill a Hole In The Wall
5-7mm
(0.2~0.3")

Outdoor
The wall you select should be strong and
solid enough to prevent vibration
1. Mount the installation plate on the wall
with
type "A" screws. If mounting the unit on a
concrete wall, use anchor bolts.
• Mount the installation plate horizontally by
aligning the centerline using a level.
2. Measure the wall and mark the centerline.
It is also important to use caution
concerning the location of the installation
plate-routing of the wiring to power outlets
is through the walls typically. Drilling the
hole through the wall for piping
connections must be done safely.

Flaring Work
Cut the pipes and the cable.
1. Use the piping kit accessory or the pipes
purchased locally.
2. Measure the distance between the indoor and
the outdoor unit.
3. Cut the pipes a little longer than measured
distance.
4. Cut the cable 1.5m(59.1in) longer than the
pipe length.
Burrs removal
1. Completely remove all burrs from the cut cross
section of pipe/tube.
2. Put the end of the copper tube/pipe in a
downward direction as you remove burrs in
order to avoid dropping burrs into the tubing.
Putting nut on
• Remove flare nuts attached to indoor and
outdoor unit, then put them on pipe/tube having
completed burr removal.
(not possible to put them on after flaring work)
Flaring work
• Carry out flaring work using flaring tool as
shown below.
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the
following procedure.

Installation
Indoor
1. Prepare the indoor unit's piping and drain hose for installation through the wall.
2. Remove the plastic tubing retainer(see the
illustration by) and pull the tubing and drain
hose away from chassis.
3. Replace only the plastic tubing holder 1, not
the holder 2 in the original position.
Route the indoor tubing and the drain hose in
the direction of rear left.
Insert the connecting cable into the indoor unit
from the outdoor unit through the piping hole.
• Do not connect the cable to the indoor unit.
• Make a small loop with the cable for easy
connection later.
Tape the tubing, drain hose and the connecting
cable. 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.
NOTE: If the drain hose is routed inside the room,
insulate the hose with an insulation material* so that
dripping from "sweating"(condensation) will not
damage furniture or floors.
*Foamed polyethylene or equivalent is
recommended.
Indoor unit installation
• Hook the indoor unit onto the upper portion of
the installation plate.(Engage the three hooks
of the rear top and rear lower of the indoor
unit with the upper edge and lower edge of the
installation plate.) Ensure that the hooks are
properly seated on the installation plate by
moving it left and right.
