PRECAUTIONS FOR SAFETY
PRECAUTIONS FOR SAFETY
Read the precautions in
this manual carefully before
operating the unit.
This appliance is filled with R32.
• Before installation, please read these precautions for safety carefully.
• Be sure to follow the precautions provided here to avoid safety risks. The
symbols and their meanings are shown below.
WARNING : It indicates that incorrect use of this unit may cause severe injury or
death.
CAUTION : It indicates that incorrect use of this unit may cause personal injury
(*1), or property damage (*2).
*1: Personal injury means a slight accident, burn, or electrical shock
which does not require admission or repeated hospital treatment.
*2: Property damage means greater damage which affects assets or
resources.
For general public use
Power supply cord and connecting cable of appliance use shall be at least
polychloroprene sheathed flexible cord (design H07RN-F) or cord designation
60245 IEC66. (Shall be installed in accordance with national wiring regulations.)
CAUTION
This appliance must be connected to the main power supply by means of a circuit
breaker or a switch with a contact separation of at least 3 mm in all poles.
DANGER
• FOR USE BY QUALIFIED PERSONS ONLY.
• TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY
ELECTRICAL WORK. MAKE SURE ALL POWER SWITCHES ARE OFF.
FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK.
• CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING
CABLE IS CONNECTED WRONGLY, ELECTRIC PARTS MAY BE DAMAGED.
• CHECK THE EARTH WIRE THAT IT IS NOT BROKEN OR DISCONNECTED
BEFORE INSTALLATION.
• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR
GAS VAPORS.
FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR
EXPLOSION.

• TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE
HAZARD, PLACE THE UNIT WELL AWAY (MORE THAN 2 M) FROM HEAT
SOURCES SUCH AS RADIATORS, HEATERS, FURNACE, STOVES, ETC.
• WHEN MOVING THE AIR CONDITIONER FOR INSTALLING IT IN ANOTHER
PLACE AGAIN, BE VERY CAREFUL NOT TO GET THE SPECIFIED
REFRIGERANT (R32) WITH ANY OTHER GASEOUS BODY INTO THE
REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED IN THE
REFRIGERANT, THE GAS PRESSURE IN THE REFRIGERATION CYCLE
BECOMES ABNORMALLY HIGH AND IT RESULTINGLY CAUSES BURST OF
THE PIPE AND INJURIES ON PERSONS.
• IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE
DURING THE INSTALLATION WORK, IMMEDIATELY LET FRESH AIR
INTO THE ROOM. IF THE REFRIGERANT GAS IS HEATED BY FIRE OR
SOMETHING ELSE, IT CAUSES GENERATION OF POISONOUS GAS.
WARNING
• Never modify this unit by removing any of the safety guards or bypassing any of
the safety interlock switches.
• Do not install in a place which cannot bear the weight of the unit.
Personal injury and property damage can result if the unit falls.
• Before doing the electrical work, attach an approved plug to the power supply
cord.
Also, make sure the equipment is properly earthed.
• Appliance shall be installed in accordance with national wiring regulations.
If you detect any damage, do not install the unit. Contact your dealer
immediately.
• Do not use any refrigerant different from the one specified for complement or
replacement.
Otherwise, abnormally high pressure may be generated in the refrigeration
cycle, which may result in a failure or explosion of the product or an injury to
your body.
• Do not use means to accelerate the defrosting process or to clean, other than
those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously operating ignition
sources (for example: open flames, an operating gas appliance or an operating
electric heater).
• Be aware that refrigerants may not contain an odour.
• Do not pierce or burn as the appliance is pressurized. Do not expose the
appliance to heat, flame, sparks, or other sources or ignition. Else, it may
explode and cause injury or death.
2

• For R32 model, use pipes, flare nut and tools which is specified for R32
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 of copper pipes used R32 must be more than 0.8 mm. Never use
copper pipes thinner than 0.8 mm.
• Do not perform flare connection inside a building or dwelling or room, when
joining the heat exchanger of indoor unit with interconnection piping. Refrigerant
connection inside a building or dwelling or room must be made by brazing or
welding. Joint connection of indoor unit by flaring method can only be made
at outdoor or at outside of building or dwelling or room. Flare connection may
cause gas leak and flammable atmosphere.
• After completion of installation or service, confirm there is no leakage of
refrigerant gas. It may generate toxic gas when the refrigerant contacts with fire.
• Appliance and pipe-work shall be installed, operated and stored in a room with a
floor area larger than Amin m2.
How to get Amin m2: Amin = (M / (2.5 x 0.22759 x h0))2
M is the refrigerant charge amount in appliance in kg. h0is the installation height
of the appliance in m: 0.6 m for floor standing/1.8 m for wall mounted/1.0 m
for window mounted/2.2 m for ceiling mounted (For these units recommend
installation height 1.0 m or less.).
• Comply with national gas regulations.
CAUTION
• Exposure of unit to water or other moisture before installation could result in
electric shock.
Do not store it in a wet basement or expose to rain or water.
• After unpacking the unit, examine it carefully for possible damage.
• Do not install the unit at place where leakage of flammable gas may occur. In
case gas leaks and accumulates at surrounding of the unit, it may cause of fire.
• Do not install in a place that can increase the vibration of the unit. Do not
install in a place that can amplify the noise level of the unit or where noise and
discharged air might disturb neighbors.
• To avoid personal injury, be careful when handling parts with sharp edges.
• Please read this installation manual carefully before installing the unit. It contains
further important instructions for proper installation.
• The manufacturer shall not assume any liability for the damage caused by not
observing the description of this manual.

Air filters
Clean every 2 weeks.
1. Open the air inlet grille.
2. Remove the air filters.
3. Vacuum or wash and then dry them.
4. Reinstall the air filters and close the air inlet grille.
Filter
Maintenance & Shelf-life
Clean every 3-6 months when dust tuck or covers the filter.
1. Recommend to use vacuum to clean by sucking the dusts which stick or dip inside the filter or use the blower to blow the dust go out through the filter.
2. If necessary to use water to clean, simply use the plain water to wash the filter, dry with the sunlight for 3-4 hours or until it completely dry.
Nevertheless, use hair dryer to dry it. However, washing with water, it may reduce the performance of the filter.
3. Replace every 2 years or sooner. (contact your dealer to purchase new filter) (P/N : RB-A620DE)
Note: Filter life depends on the level of impurities in your operating environment. Higher levels of impurities may require more frequent cleaning and
replacement. In all cases, we recommend an additional set of filters to improve the purifying and deodorizing performance of your air conditioner.

Remote control selector switch
•When two indoor units are installed in the same room or adjacent two
rooms, if operating a unit, two units may receive the remote control
signal simultaneously and operate. In this case, the operation can
be preserved by setting either one indoor unit or remote control to B
setting (Both are set to A setting in factory shipment).
•The remote control signal is not received when the settings of indoor
unit and remote control are different.
•There is no relation between A setting/B setting and A room/B room
when connecting the piping and cables.
When two indoor units are installed in the separated rooms, it is not
necessary to change the selector switches.
