2.1

Caution Concerning New Refrigerant Series

Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid
state. (If the refrigerant is charged in a state of gas, its composition changes and the system will not
work properly.)
The indoor/outdoor unit is for R410A. See the catalog for indoor/outdoor unit models which can be
connected. (Normal operation is not possible when connected to other units.)
2.2

Precautions

NOTE:
Installation Manual BS Unit
When moving the unit while removing it from the packing case, be sure to lift it by
holding on to the four hunger brackets without exerting any pressure on other parts,
especially, the refrigerant piping.
Be sure to check the type of R410A refrigerant to be used before installing the unit. (Using an
incorrect refrigerant will prevent normal operation of the unit.)
The accessories needed for installation must be retained in your custody until the installation
work is completed. Do not discard them!
Do not install or operate the unit in rooms mentioned below.
• Laden with mineral oil, or filled with oil vapor or spray like in kitchens. (Plastic parts
may deteriorate which could eventually cause the unit to fall out of place, or could lead
to leaks.)
• Where corrosive gas like sulfurous gas exists. (Copper tubing and brazed sports may
corrode, which could eventually lead to refrigerant leaks.)
• Where exposed to combustible gases and where volatile flammable gas like thinner or
gasoline is used. (Gas in the vicinity of the unit could ignite.)
• Where machines can generate electromagnetic waves. (Control system may
malfunction.)
• Where the air contains high levels of salt such as that near the ocean and where voltage
fluctuates greatly such as that in factories. Also in vehicles or vessels.
Refer to the installation manual provided with the outdoor and the indoor unit.
If installed as a household appliance it could cause electromagnetic interference.
Be sure to read this manual before installing the indoor unit.
Entrust installation to the place of purchase or a qualified serviceman. Improper installation
could lead to leaks and, in worse cases, electric shock of fire.
Use only parts provided with the unit or parts satisfying required specifications. Unspecified
parts could cause the unit to fall out of place, or could lead to leaks and, in worse cases, electric
shock or fire.
