• Do not change the setting of the protection devices. If

the pressure switch, thermal switch, or other protec-

tion device is shorted and operated forcibly, or parts

other than those specified by Daikin are used, fire or

explosion may occur.

CAUTION

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

switch with wet fingers can cause electric shock.

• Do not allow children to play on or around the unit to

prevent injury.

• Do not touch the refrigerant pipes during and immedi-

ately after operation as the refrigerant pipes may be

hot or cold, depending on the condition of the refriger-

ant flowing through the refrigerant piping, compres-

sor, and other refrigerant cycle parts. Your hands may

suffer 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.

• Heat exchanger fins are sharp enough to cut.

To avoid injury wear glove or cover the fins when work-

ing around them.

• Install drain piping to proper drainage. Improper drain

piping may result in water leakage and property dam-

age.

• 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

occur.

• Do not use a charging cylinder. Using a charging cylin-

der may cause the refrigerant to deteriorate.

• Refrigerant R-410A 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 -- R-410A does not contain any chlorine, does

not destroy the ozone layer, and does not reduce the

earth’s protection again harmful ultraviolet radia-

tion. R-410A 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 R-410A is a blend, the required additional refrig-

erant must be charged in its liquid state. If the refriger-

ant is charged in a state of gas, its composition can

change and the system will not work properly.

• The indoor unit is for R-410A. See the catalog for in-

door 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

fluorescent 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.

• Do not install the air conditioner in the following loca-

tions:

(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 or 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 malfunc-

tion.

(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 gaso-

line are handled. Operating the unit in such condi-

tions can cause a fire.

• Take adequate measures to prevent the outside unit

from being used as a shelter by small animals. Small

animals making contact with electrical parts can cause

malfunctions, smoke, or fire. Instruct the customer to

keep the area around the unit clean.

NOTE

• Install the power supply and control wires for the

indoor and outdoor units at least 3.5 feet away from

televisions or radios to prevent image interference or

noise. Depending on the radio waves, a distance of 3.5

feet 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 R-410A, the refrigerant may deteriorate.

• This air conditioner is an appliance that should not be

accessible to the general public.

• The wall thickness of field-installed pipes should be

selected in accordance with the relevant local, state,

and national regulations.
