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.
2.6. Additional charge
CAUTION
When adding refrigerant, add the refrigerant from the charging port at the completion
of work.
Refrigerant suitable for a piping length of 49ft (15m) is charged in the outdoor unit at the
factory.
When the piping is longer than 49ft (15m), additional charging is necessary.
For the additional amount, refer to the following table.

3. INSTALLATION WORK
Make sure to obtain the customer’s approval for selecting and installing the outdoor unit.
3.1. Selecting an installation location
WARNING
• Securely install the outdoor unit at a location that can withstand the weight of the
unit. Otherwise, the outdoor unit may fall and cause injury.
• Be sure to install the outdoor unit as prescribed, so that it can withstand earthquakes
and typhoons or other strong winds. Improper installation can cause the unit to
topple or fall, or other accidents.
• Do not install the outdoor unit near the edge of a balcony. Otherwise, children may
climb onto the outdoor unit and fall off of the balcony.
2.3. Pipe requirement
2.3.1. Protection of pipes
• Protect the pipes to prevent the entry of moisture and dust.
• Especially, pay attention when passing the pipes through a hole or connecting the end
of a pipe to the outdoor unit.
Location Working period Protection method
Outdoor
1 month or more Pinch pipes
Less than 1 month Pinch or tape pipes
Indoor - Pinch or tape pipes
2.3.2. Refrigerant pipe size and allowable piping length
CAUTION
• Keep the piping length between the indoor unit and outdoor unit within the allowable
tolerance.
• The maximum lengths of this product are shown in the table. If the units are further
apart than this, correct operation cannot be guaranteed.

2.4. Power source
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 current of other electrical appliances. When the current contracted capacity is
insuffi cient, change the contracted capacity.
• When the voltage is low and the air conditioner is diffi cult to start, contact the power
company the voltage raised.
2.5. Electric requirement
CAUTION
• Be sure to install a breaker of the specifi ed capacity.
• Regulation of cables and breaker differs from each locality, refer in accordance with
local rules.
