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.
! WARNING
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.
• The choice of materials and installations must comply with the applicable local/national or international
standards.
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
Make sure that the screws of the terminal are free from looseness.
! CAUTION
The Power cord connected to the unit should be selected according to the following specifications.
! CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have separate power specially for the air conditioner. As for the method of
wiring, follow the circuit diagram pasted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose
from vibrations to which the unit is subjected during the course of transportation. Check
them and make sure that they are all tightly fastened. (If they are loose, it could give rise to
burn-out of the wires.)
4) Confirm the Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Do not install the leakage breaker in a place which is wet or moist.
Water or moist may cause short circuit.
9) The following troubles would be caused by voltage drop-down.
- Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device.
- Proper starting power is not given to the compressor.

Airborne Noise Emission
The A-weighted sound pressure emitted by this product is below 70 dB.
** The noise level can vary depending on the site.
The figures quoted are emission level and are not necessarily safe working levels. Whilst there is
a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factor that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of
noise, i.e. the number of equipment and other adjacent processes and the length of time for
which an operator exposed to the noise. Also, the permissible exposure level can vary from
country to country. This information, however, will enable the user of the equipment to make a
better evaluation of the hazard and risk.
Limiting concentration
Limiting concentration is the limit of Freon gas concentration where immediate measures can be
taken without hurting human body when refrigerant leaks in the air. The limiting concentration
shall be described in the unit of kg/m3(lbs/ft3) (Freon gas weight per unit air volume) for facilitating calculation
Limiting concentration: 0.44 kg/m3 (0.027 lbs/ft3) (R410A)
■ Calculate refrigerant concentration
Refrigerant concentration =
Total amount of replenished refrigerant in refrigerant facility [kg(lbs)]
Capacity of smallest room where indoor unit is installed [m3(ft3)]
