6.
Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water leakage,
fire or electrical shock.
7.
Install at a strong and firm location which is able to withstand the set's weight. If the strength is not enough or installation is not properly
done, the set will drop and cause injury.
8.
For electrical work, follow the local national wiring standard, regulation and the installation instruction. An independent circuit and single
outlet must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.
9.
10.
11.
This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD).
Otherwise, it may cause electrical shock and fire in case equipment breakdown or insulation breakdown.
Do not use joint cable for indoor/outdoor connection cable. Use the specified indoor/outdoor connection cable, refer to installation
instruction CONNECT THE CABLE TO THE INDOOR UNIT and connect tightly for indoor/outdoor connection. Clamp the cable so that no
external force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat up or fire at the connection.
Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will
cause heat-up or fire at connection point of terminal, fire or electrical shock.
12.
When install or relocate air conditioner, do not let any substance other than the specified refrigerant, eg. air etc. mix into refrigeration
cycle (piping). (Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.).
13.
Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit at veranda of high rise building, child may climb
up to outdoor unit and cross over the handrail and causing accident.
14.
This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and
telephone. Otherwise, it may cause electrical shock in case equipment breakdown or insulation breakdown.
15.
Keep away from small children, the thin film may cling to nose and mouth and prevent breathing.
16.
Do not use unspecified cord, modified cord, joint cord or extension cord for power supply cord. Do not share the single outlet with
other electrical appliances. Poor contact, poor insulation or over current will cause electrical shock or fire.
17.
18.
19.
Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the
flare may break and cause refrigerant gas leakage.
For R410A model, use piping, flare nut and tools which is specified for R410A refrigerant. Using of existing (R22) piping, flare nut
and tools may cause abnormally high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury.
Thickness or copper pipes used with R410A must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.
It is desirable that the amount of residual oil less than 40 mg/10 m.
During installation, install the refrigerant piping properly before run the compressor. (Operation of compressor without fixing refrigeration
piping and valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury
etc.).

Cooling capacities are based on indoor temperature of 27°C Dry Bulb (80.6°F Dry Bulb), 19.0°C Wet Bulb (66.2°F Wet Bulb) and outdoor air
temperature of 35°C Dry Bulb (95°F Dry Bulb), 24°C Wet Bulb (75.2°F Wet Bulb)
Heating capacities are based on indoor temperature of 20°C Dry Bulb (68°F Dry Bulb) and outdoor air temperature of 7°C Dry Bulb (44.6°F
Dry Bulb), 6°C Wet Bulb (42.8°F Wet Bulb)
Heating low temperature capacity, Input Power and COP measured at 230 V, indoor temperature 20°C, outdoor 2/1°C.
Heating extreme low temperature capacity, Input Power and COP measured at 230 V, indoor temperature 20°C, outdoor -7/-8°C.
Specifications are subjected to change without prior notice for further improvement.
Maximum heating capacity shown are the values based on powerful operation.
If the EUROVENT Certified models can be operated under the “extra-low” temperature condition, -7°C DB and -8°C WB temperature with
rated voltage 230V shall be used.
The annual consumption is calculated by multiplying the input power by an average of 500 hours per year in cooling mode.
SEER and SCOP classification is at 230V only in accordance with EN-14825. For heating, SCOP indicates the value of only Average heating
season. Other fiche data indicates in an attached sheet.

12. Operation and Control
12.1 Basic Function
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time
passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating
mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and
performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by
the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air
temperature.
12.1.1
Internal Setting Temperature
Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting
processes.
These shifting processes are depending on the air conditioner settings and the operation environment. The final
shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power
is supplied to the unit.

Automatic Operation
This mode can be set using remote control and the operation is decided by remote control setting temperature,
remote control operation mode and indoor intake air temperature.
During operation mode judgment, indoor fan motor (with speed of Lo-) is running for 30 seconds to detect the
indoor intake air temperature.
Every 10 minutes, the indoor temperature is judged.
For the 1st judgment
o If indoor intake temperature - remote control setting temperature ≥ 2°C, COOL mode is decided.
o If -2°C ≤ indoor intake temperature - remote control setting temperature < 2°C, DRY mode is decided.
o If indoor intake temperature - remote control setting temperature < -2°C, HEAT mode is decided.

In order to diagnose malfunctions, make sure that
there are no electrical problems before inspecting the
refrigeration cycle.
Such problems include insufficient insulation, problem
with the power source, malfunction of a compressor
and a fan.
The normal outlet air temperature and pressure of the
refrigeration cycle depends on various conditions, the
standard values for them are shown in the table on the
