 CAUTION

•  Do not touch the switch with wet fingers. Touching a switch 

with wet fingers may result in electric shock.

• 

Do not allow children to play on or around the unit or it 
may result in injury.

•  The heat exchanger fins are sharp enough to cut, and 

may result in injury if improperly used. To avoid injury wear 

glove or cover the fins when working around them.

• 

Do not touch the refrigerant pipes during and immediately 
after operation as the refrigerant pipes may be hot or 

cold, depending on the condition of the refrigerant flow

-

ing through the refrigerant piping, compressor, and other 
refrigerant cycle parts. It may result in your hands get-
ting burns or frostbite if you touch the refrigerant pipes. 
To avoid injury, give the pipes time to return to normal 
temperature or, if you must touch them, be sure to wear 
proper gloves.

• 

Install drain piping to proper drainage. Improper drain pip-
ing may result in water leakage and property damage.

• 

Insulate piping to prevent condensation.

• 

Be careful when transporting the product.

• 

Do not turn off the power immediately after stopping 
operation. Always wait for at least 5 minutes before turning 
off the power. Otherwise, water leakage may result.

• 

Do not use a charging cylinder. Using a charging cylinder 
may cause the refrigerant to deteriorate.

• 

Refrigerant R410A in the system must be kept clean, dry, 
and tight.
(a)  Clean and Dry - Foreign materials (including mineral 

oils such as SUNISO oil or moisture) should be pre-
vented from getting into the system.

(b)  Tight - R410A does not contain any chlorine, does 

not destroy the ozone layer, and does not reduce the 
earth’s protection again harmful ultraviolet radiation. 
R410A can contribute to the greenhouse effect if it is 
released. Therefore take proper measures to check 
for the tightness of the refrigerant piping installation. 
Read the chapter Refrigerant Piping and follow the 
procedures.

• 

Since R410A is a blend, the required additional refriger-
ant must be charged in its liquid state. If the refrigerant is 
charged in a state of gas, its composition can change and 
the system will not work properly.

• 

The indoor unit is for R410A. See the catalog for indoor 
models that can be connected. Normal operation is not 
possible when connected to other units.

• 

Remote controller (wireless kit) transmitting distance can 

be shorter than expected in rooms with electronic fluores

-

cent lamps (inverter or rapid start types). Install the indoor 

unit far away from fluorescent lamps as much as possible.

• 

Indoor units are for indoor installation only. Outdoor units 
can be installed either outdoors or indoors. This unit is for 
indoor use.

• 

Do not install the air conditioner or heat pump in the fol-
lowing locations:
(a)  Where a mineral oil mist or oil spray or vapor is pro-

duced, for example, in a kitchen.

Plastic parts may deteriorate and fall off and thus may 
result in water leakage.

(b)  Where corrosive gas, such as sulfurous acid gas, is 

produced.
Corroding copper pipes or soldered parts may result 
in refrigerant leakage.

(c)  Near machinery emitting electromagnetic waves.

Electromagnetic waves may disturb the operation of 

the control system and cause the unit to malfunction.

(d) 

Where flammable gas may leak, where there is car

-

bon fiber, or ignitable dust suspension in the air, or 
where volatile flammables such as thinner or gasoline 

are handled. Operating the unit in such conditions 

may result in a fire.

• 

Take adequate measures to prevent the outdoor unit from 
being used as a shelter by small animals. Small animals 
making contact with electrical parts may result in malfunc-

tions, smoke, or fire. Instruct the customer to keep the 

area around the unit clean.

 NOTE

• 

Install the power supply and transmission wires for the in-

door and outdoor units at least 3.5 ft. (1 m) away from tele

-

visions or radios to prevent image interference or noise. 

Depending on the radio waves, a distance of 3.5 ft. (1 m) 
may not be sufficient to eliminate the noise.

• 

Dismantling the unit, treatment of the refrigerant, oil and 
additional parts must be done in accordance with the 
relevant local, state, and national regulations.

• 

Do not use the following tools that are used with con-
ventional refrigerants: gauge manifold, charge hose, gas 

leak detector, reverse flow check valve, refrigerant charge 

base, vacuum gauge, or refrigerant recovery equipment.

• 

If the conventional refrigerant and refrigerator oil are 

mixed in R410A, the refrigerant result in deterioration.

• 

This air conditioner or heat pump is an appliance that 
should not be accessible to the general public.

• 

As design pressure is 478 psi (3.3 MPa), the wall thick-

ness of field-installed pipes should be selected in accor

-

dance with the relevant local, state, and national regula-
tions.
