08_ safety information
safety information
CAUTION SIGNS
Make sure the voltage and frequency of the electric system are compatible with the
air conditioner.
If a power outage occurs while the air conditioner is working, turn off the power
source immediately.
Max current is measured according to IEC standard for safety and current is
measured according to ISO standard for energy efficiency.
The unit must be plugged into an independent circuit if applicable or connect the
power cable to the auxiliary circuit breaker. An all pole disconnection from the power
supply must be incorporated in the fixed wiring with a contact opening of >3mm.
After connecting the power cable between the indoor/outdoor unit, attach the cover
of component box securely and make sure it is not loose.
For the power cable, use the grade of H07RN-F or H05RN-F materials.
The unbalanced power must be maintained within 10% of supply rating among whole
indoor units.
If the power is unbalanced greatly, it may shorten the life of the condenser.
If the unbalanced power is exceeded over 10% of supply rating, the indoor unit is
protected, stopped and the error mode indicates.
To protect the product from water and possible shock, you should keep the power
cable and the connection cord of the indoor and outdoor units in the protection tube.
Connect the power cable to the auxiliary circuit breaker.
You must keep the cable in a protection tube.
Keep distances of 50mm or more between power cable and communication cable.
Maximum length of power cable is decided within 10% of power drop. If it exceeds,
you must consider another power supplying method.
The circuit breaker (MCCB, ELB) should be considered more capacity, if many indoor
units are connected from one breaker.
Use solderless ring terminal to connect the power cable to the power terminal block.
Use an appropriate screwdriver for tightening the terminal screws.
Over-tightening the terminal screws may break them.
The air conditioner should be used only for the applications for which it has been
designed: the indoor unit is not suitable to be installed in areas used for laundry.
Our units must be installed in compliance with the spaces indicated in the installation
manual to ensure either accessibility from both sides or ability to perform routine
maintenance and repairs. The units’ components must be accessible and that can
be disassembled in conditions of complete safety either for people or things. For this
reason, where it is not observed as indicated into the Installation Manual, the cost
necessary to reach and repair the unit (in safety, as required by current regulations
in force) with slings, trucks, scaffolding or any other means of elevation won’t be
considered in-warranty and charged to end user.
Ensure the off-on and protection switches are properly installed.
Do not use the air conditioner if damaged. If problems occur, immediately stop
operation and disconnect the plug from the power supply.
If the air conditioner will not be used for an extended period of time (for example, over
several months), unplug the power from the wall.
Call the place of purchase or a contact center if repairs are needed.
• Potential risk of fire or electric shock if disassembly or repairs are attempted by a non-qualified
service technician.
If you smell burning plastic, hear strange sounds, or see smoke coming from the unit,
unplug the air conditioner immediately and call a contact center.
• Potential risk of fire or electric shock.

TIPS ON USING AIR CONDITIONER
Here are some tips that you would follow when using your air conditioner.
TOPIC RECOMMENDATION
Cooling • If current outside temperatures are much higher than the selected indoor
temperature, it may take time to bring the inner temperature to the desired
coolness.
• Avoid drastically turning down the temperature. Energy is wasted and the
room does not cool faster.
Heating • Since the air conditioner heats the room by taking heat energy
from outdoor air, the heating capacity may decrease when outdoor
temperatures are extremely low. If you feel the air conditioner insufficiently
heats, using an additional heating appliance in combination with the air
conditioner is recommended.
Frost & De-ice • When the air conditioner runs in Heat mode, due to temperature difference
between the unit and the outside air, frost will form.
If this happens:
- The air conditioner stops heating.
- The air conditioner will operate automatically in De-ice mode for
10 minutes.
- The steam produced on the outdoor unit in De-ice mode is safe.
No intervention is required; after about 10 minutes, the air conditioner
operates again normally.
The unit will not operate when it starts to de-ice.
Fan • Fan may not operate for about 3~5 minutes at the beginning to prevent
any cold blasts while the air conditioner is warming up.
High indoor/outdoor
temperatures
• If both indoor and outdoor temperatures are high and the air conditioner is
running in Heat mode, the outdoor unit’s fan and compressor may stop at
times. This is normal; wait until the air conditioner turns on again.
Power failure • If a power failure occurs during the operation of the air conditioner, the
operating immediately stops and unit will be off. When power returns, the
air conditioner will run automatically.
Protection mechanism • If the air conditioner has just been turned on after operation stops or being
plugged in, cool/warm air does not come out for 3 minutes to protect the
compressor of the outdoor unit.
