4. Pb free solder has a higher melting point than standard solder; typically the melting point is 50 - 70qF (30 - 40qC) higher. Please use
a high temperature solder iron. In case of the soldering iron with temperature control, please set it to 700 ± 20qF (370 ± 10qC).
Pb free solder will tend to splash when heated too high (about 1100qF / 600qC).
5. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare
may break and cause refrigerant gas leakage.
6. Do not touch outdoor unit air inlet and aluminium fin. It may cause injury.
AT T E N T I O N
1. Selection of the installation location. Select an installation location which is rigid and strong enough to support or hold the unit, and select a
location for easy maintenance.
2. Power supply connection to the conditioner. Connect the power supply cord of the air conditioner to the mains using one of the following
methods.
Power supply point shall be the place where there is ease for 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 3.5 mm contact gap.
3. Do not release refrigerant during piping work for installation, servicing, reinstallation and during repairing a refrigeration parts. Take care of
the liquid refrigerant, it may cause frostbite.
4. Installation work. It may need two people to carry out the installation work.
5. Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
