• Do not install in a place that might increase the vibration of the unit.

• To avoid personal injury (with sharp edges), be careful when handling parts.

• Perform installation work properly according to the Installation Manual.

Inappropriate installation may result in water leakage, electric shock or fire.

• When the air conditioner is installed in a small room, provide appropriate measures to

ensure that the concentration of refrigerant leakage occur in the room does not exceed the

critical level.

• Install the air conditioner securely in a location where the base can sustain the weight

adequately.

• Perform the specified installation work to guard against an earthquake.

If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.

• If refrigerant gas has leaked during the installation work, ventilate the room immediately.

If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.

• After the installation work, confirm that refrigerant gas does not leak.

If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas might

generate.

• Electrical work must be performed by a qualified electrician in accordance with the

Installation Manual. Make sure the air conditioner uses an exclusive power supply.

An insufficient power supply capacity or inappropriate installation may cause fire.

• Use the specified cables for wiring connect the terminals securely fix. To prevent external

forces applied to the terminals from affecting the terminals.

• Conform to the regulations of the local electric company when wiring the power supply.

•Be sure to use a double spanner to connect the pipes.

•Using a torque wrench, tighten surely with the specified tightening torque the connecting section of flare pipes which connect each unit of the indoor and outdoor units. For the tightening torque, see the following table.

Outer dia. of	Tightening torque
connecting pipe (mm)	(N-m)
Ø6.4	14 to 18 (1.4 to 1.8kgf-m)
Ø9.5	14 to 18 (1.4 to 1.8kgf-m)
Ø12.7	14 to 18 (1.4 to 1.8kgf-m)
Ø15.9	14 to 18 (1.4 to 1.8kgf-m)

Thermal Insulating Process

•Apply thermal insulation to pipes at liquid side and gas side separately.

•Using thermal insulators attached to this part and the indoor unit, apply thermal insulation to connecting section of the pipes surely without clearance.

If a combustible gas leaks, and stays around the unit, a fire may occur.

Fix it with vinyl tape. Set the notch upward.

Before Installation

Before installation, open the draw port of the upper pipes. (Sheeted knockout hole)
