2.3. Pipe requirements

• Do not use existing pipes.

• Use pipes that have clean external and internal sides without any contamination which

may cause trouble during use, such as sulfur, oxide, dust, cutting waste, oil, or water.

• It is necessary to use seamless copper pipes.

Material: Phosphor deoxidized seamless copper pipes.

It is desirable that the amount of residual oil is less than 0.004 oz/100 ft (40 mg/10 m).

• Do not use copper pipes that have a collapsed, deformed, or discolored portion

(especially on the interior surface). Otherwise, the expansion valve or capillary tube

may become blocked with contaminants.

• Improper pipe selection will degrade performance. As an air conditioner using R410A

incurs pressure higher than when using conventional refrigerant, it is necessary to

choose adequate materials.

• Thicknesses of copper pipes used with R410A are as shown in the table.

• Never use copper pipes thinner than those indicated in the table even if they are

available on the market.

2.3.1. Refrigerant pipe size and allowable piping length

• 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.

2.3.2. 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.

2.4. Power source

• 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 1/8 in (3 mm)

between the contacts of each pole.

• 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 insufficient,

change the contracted capacity.

• When the voltage is low and the air conditioner is difficult to start, contact the power

company the voltage raised.

2.5. Electrical requirements

• Be sure to install a breaker of the specified capacity.

• Before the electrical work, confirm electrical standards and regulations in each

country, region, or installing place. Then select appropriate cables and breakers that

comply with them.

• This unit must be connected to a power supply with impedance of 0.419 ohm and below.

If the power supply does not satisfy this requirement, please consult the power supplier.

• Select the correct cable type and size according to the country or region's regulations.

• Select the breaker so 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 relevant national regulations.

• Install the disconnect device with a contact gap of at least 1/8 in (3 mm) in all poles

nearby the units. (Both indoor unit and outdoor unit)

• Install the circuit breaker nearby the units.
