explosion and injury.
9.
Thickness of copper pipes used must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.
10. It is desirable that the amount of residual oil is less than 40 mg/10 m.
11. Do not modify the length of the power supply cord or use of the extension cord, and do not share the single outlet with other
electrical appliances. Otherwise, it will cause fire or electrical shock.

1.
The equipment must be earthed. It may cause electrical shock if grounding is not perfect.
2.
Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding
of the unit, it may cause fire.

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).
