Pb free solder has a higher melting point than standard solder; typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a
high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700

20°F (370

10°C).

Pb free solder will tend to splash when heated too high (about 1100°F/600°C).

1.

Selection of the installation location. Select an installation location which is rigid and strong enough to support or hold the unit, and select

following methods. Power supply point shall be the place where there is ease for access for the power disconnection in case of
emergency.
In some countries, permanent connection of this room air conditioner to the power supply is prohibited.
 1. 

Power supply connection to the receptacle using a power plug. Use an approved power plug with earth pin for the connection to the
socket.

 2. 

Power supply connection to a circuit breaker for the permanent connection. Use an approved circuit breaker for the permanent
connection. It must be a double pole switch with a minimum 4/32 inches contact gap.

3.

Do not release refrigerant during piping work for installation, servicing, reinstallation and during repairing a refrigeration parts. Take care
