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 immediately after operation as the refrigerant
pipes may be hot or cold, depending on the condition of the refrigerant flowing through the
refrigerant piping, compressor, 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 working around them.
•
Install drain piping to proper drainage. Improper drain piping 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 supply immediately after stopping operation. Always wait for at least
5 minutes before turning off the power supply. Otherwise, water leakage may occur.
•
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 prevented 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 refrigerant 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 fluorescent lamps (inverter or rapid start types). Install the indoor unit far away
from fluorescent lamps as much as possible.
•
Indoor and outside units are for indoor installation only.
•
Do not install the air conditioner in the following locations:
(a) Where a mineral oil mist or oil spray or vapor is produced, 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 malfunction.
(d)
Where flammable gas may leak, where there is carbon 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 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.
