Installation Location

• We recommend that this air conditioner be installed properly by qualified installation

technicians in accordance with the Installation Instructions provided with the unit.

• Before installation, check that the voltage of the electric supply in your home or office is the

same as the voltage shown on the nameplate.

• Do not install this air conditioner where there are fumes or flammable gases, or in an extremely humid space such as a greenhouse.

• Do not install the air conditioner where excessively high heat-generating objects are placed.

Avoid: To protect the air conditioner from heavy corrosion, avoid installing the outdoor unit where

salty sea water can splash directly onto it or in sulphurous air near a spa.

Electrical Requirements

1. All wiring must conform to the local electrical codes. Consult your dealer or a qualified electrician for details.

2. Each unit must be properly grounded with a ground (or earth) wire or through the supply wiring.

3. Wiring must be done by a qualified electrician.

To warm up the system, the power mains must be turned on at least five (5) hours before operation. Leave the power mains ON unless you will not be using this appliance for an extended period.

Safety Instructions

• Read this Instruction Manual carefully before using this air conditioner. If you still have

any difficulties or problems, consult your dealer for help.

• This air conditioner is designed to give you comfortable room conditions. Use this only

for its intended purpose as described in this Instruction Manual.

• Never touch the unit with wet hands.

• Never use or store gasoline or other flammable vapor or liquid near the air conditioner — it is very dangerous.

• This air conditioner has no ventilator for intaking fresh air from outdoors. You must open doors or windows frequently when you use gas or oil heating appliances in the same room, which consume a lot of oxygen from the air. Otherwise there is a risk of suffocation in an extreme case.

• Do not turn the air conditioner on and off from the power mains switch. Use the ON/ OFF operation button.

• Do not stick anything into the air outlet of the outdoor unit. This is dangerous because the fan is rotating at high speed.

• Do not let children play with the air conditioner.

• Do not cool or heat the room too much if babies or invalids are present.

• The wireless remote control unit sends the temperature signal to the air conditioner regularly at five-minute intervals. If the signal from the wireless remote control unit stops for more than ten minutes due to the loss of the wireless remote control unit or other trouble, the air conditioner will switch to the temperature sensor which is built into the indoor unit and control the room temperature. In these cases, the temperature around the wireless remote control unit may differ from the temperature detected at the air conditioner’s position.

• When low fan speed is selected and the air conditioner is in cooling operation at a low outdoor temperature of less than 50°F, the air conditioner may automatically switch to medium fan speed to prevent freezing.
