6-2 Place for installation.

Please do not use the unit in the following places.

(1)Place where a lot of oil (The machine oil is contained), moistures, and dust exist.

(2)Place where a lot of salinities such as beach districts exists.

(3)Place where sulfur gas, volatile gas, and corroded gas are filled.

(4)Place where acid solution is frequently used.

(5)Place where special spray is frequently used.

(6)Hot spring zone.

(7)Never machine (high cycle welding machine etc.) generating highcycle.

(8)Place where ventilation entrance of outdoor units is closed by snowfall.

(9)The unit must be installed on stable, level surface.

The main body might corrode when the unit is used in such a place, the refrigerant leak, the performance of the unit decrease remarkably, and it cause the damage of parts of the unit.

6-3 Regarding electric work.

(1)The electrical work must be undertaken by a person who is qualified as an electric engineer according to the (technical standard respecting electrical installation), (internal wiring rules), and the installation instruction manual with the absolute use of exclusive circuits.

(2)Please install a special power supply in the power supply.

(3)Please install the earth connection for the electric shock prevention.

(4)Never connect the grounding wire to a gas pipe, water pipe, arrester, or telephone grounding wires. For details, consult with your dealer.

(5)In some types of installation sites, the installation of an earth leakage breaker is mandatory. For details, consult with your dealer.

(6)The breaker and the fuse must use the one of correct capacity.

6-4 Conseration of the noise.

(1)Take sufficient measures against noise when installing the air conditioners at hospitals or communication-related businesses.

(2)If the air conditioner is used in any of the above-mentioned environments, frequent operational failure can be excepted.

It is advisable to avoid these type of installation sites. For further details, consult with your dealer.

(3)Choose a place where cool or warm air and noise from the outdoor air outlet of the air conditioner do not inconvenience the neighbours.

(4)If any alien object is placed near the air outlet of the unit, decreased performance and increased noise can result.

Avoid placing any obstacles adjacent to the air outlet.

(5)If the air conditioner produces any abnormal sound, consult with your dealer.

6-5 Disposing of the unit.

When you need to dispose of the unit, consult your dealer.

If pipes are removed incorrectly, refrigerant (fluorocarbon gas) may blow out and come into contact with your skin, causing injury.

Releasing refrigerant into the atmosphere also damages the environments.

6-6 Maintenance and inspection.

(1)If the air conditioner is used throughout several seasons, the insides can get dirty, reducing the performance.

(2)Depending upon the conditions of usage, foul odours can be generated and drainage can deteriorate due to dust and dirt, etc.
