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.
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.
