3. GENERAL SPECIFICATION

3.1. Selecting circuit breaker and wiring

Be sure to install a breaker of the specified capacity.

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

local rules.

Voltage rating

Operating range

Cable

Power supply cable

Connection cable

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

Max. wire length: Set a length so that the voltage drop is less than 2%. Increase the wire

diameter when the wire length is long.

MINIMUM CIRCUIT AMPACITY

MAX. CKT. BKR.

• 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 2/16 in. (3mm) in all poles

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

• Install the circuit breaker nearby the units.

3.2. Selecting the pipe material

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 40 mg/33ft (10m).

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.

Note:

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.

3.3. 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.

4. INSTALLATION WORK

Make sure to obtain the customer's approval for selecting and installing the outdoor unit.

4.1. Selecting an installation location

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.
