 WARNING

To install a unit that uses R410A refrigerant, use dedicated tools and piping materials 
that have been manufactured speci

fi

 cally for R410A use. Because the pressure of 

R410A refrigerant is approximately 1.6 times higher than R22, failure to use dedicated 
piping material or improper installation can cause rupture or injury. Furthermore, it can 
cause serious accidents such as water leakage, electric shock, or 

fi

 re.

2.3. Power

 WARNING

Always use a special branch circuit and install a special receptacle to supply power to 
the room air conditioner.

Use a circuit breaker and receptacle matched to the capacity of the air conditioner.

Install a leakage circuit breaker in accordance with the related laws and regulations 
and electric company standards.

The circuit breaker is installed in the permanent wiring. Always use a circuit that can 
trip all the poles of the wiring and has an isolation distance of at least 3 mm between 
the contacts of each pole.

 CAUTION

The power source capacity must be the sum of the air conditioner current and the cur-
rent of other electrical appliances. When the current contracted capacity is insuf

fi

 cient, 

change the contracted capacity.
When the voltage is low and the air conditioner is dif

fi

 cult to start, contact the power 

company the voltage raised.

2.4. Electric requirement

 CAUTION

Be sure to install a breaker of the speci

fi

 ed capacity.

Regulation of cables and breaker differs from each locality, refer in accordance with 
local rules.

  Select the appropriate breaker of the described specification according to the national 

or regional standards.

*3

 Select the breaker that enough load current can pass through it.

  Before starting work check that power is not being supplied to all poles of the indoor 

• 

unit and outdoor unit.
 Install all electrical works in accordance to the national standard.

• 

  Install the disconnect device with a contact gap of at least 3 mm in all poles nearby the 

• 

units. (Both indoor unit and outdoor unit)

•  Install the circuit breaker nearby the units.

2.5. Additional charge

Refrigerant suitable for a piping length of 15 m is charged in the outdoor unit at the factory.
When the piping is longer than 15 m, additional charging is necessary.
Between 15 m and 20 m, when using a connection pipe other than that in the table, charge 
additional refrigerant with 20 g/1 m as the criteria.
For the additional amount, see the table below.

 CAUTION

When adding refrigerant, add the refrigerant from the charging port at the completion 
of work.
The maximum length of the piping is 20 m. If the units are further apart than this, correct 
operation can not be guaranteed.

2.6. Accessories

The following installation accessories are supplied.
Use them as required.

3.  SELECTING THE MOUNTING POSITION

•  Decide the mounting position with the customer as follows.
•  Do not set to a place where there is oily smoke, oil is used in the factory, the unit can 

contact sea breeze, sul

fi

 de gases will be generated in the hot spring area, corrosive 

gases will be generated, animal may urine on the unit and ammonia will be generated 
and a dusty place.

3.1. Outdoor unit

(1) If possible, do not install the unit where it will be exposed to direct sunlight. 

(If necessary, Install a blind that does not interfere with the air 

fl

 ow.)

(2)  Do not install the unit where a strong wind blows or where it is very dusty.
(3)  Do not install the unit where people pass.
(4)  Take you neighbors into consideration so that they are not disturbed by air blowing into their 

windows or by noise.

(5)  Provide the space shown in 

fi

 gure so that the air

fl

 ow is not blocked. Also for ef

fi

 cient 

operation, leave open three of the four directions front, rear, and both sides.

(6)  Install the unit where keep away more than 3 m from the antenna of TV set and Radio.
(7)  Outdoor unit should be set to a place where both drainage and itself will not be 

affected when heating.

 WARNING

Install at a place that can withstand the weight of the outdoor units and install positively 
so that the units will not topple or fall.

 CAUTION

Do not install where there is the danger of combustible gas leakage.
Do not install near heat sources.
If children under 10 years old may approach the unit, take preventive measures so that 
they cannot reach the unit.
