Page 5: Safety Precautions
1 SAFETY PRECAUTIONS The precautions listed here are divided into the following types.They are quite important, so be sure to follow them carefully. Meanings of DANGER, WARNING, CAUTION and NOTE symbols. INFORMATION Read these instructions carefully before installation. Keep this manual in a handy for future reference. Improper installation of equipment or accessories may result in electric shock, short-circuit, leakage, fire or other damage to the equipment. - Page 6 DANGER Before touching electric terminal parts, turn off power switch. When service panels are removed, live parts can be easily touched by accident. Never leave the unit unattended during installation or servicing when the service panel is removed. Do not touch water pipes during and immediately after operation as the pipes may be hot and could burn your hands.
- Page 7 Do not install the unit in the following places: - Where there is mist of mineral oil, oil spray or vapors. Plastic parts may deteriorate, and cause them to come loose or water to leak. - Where corrosive gases (such as sulphurous acid gas) are produced. Where corrosion of copper pipes or soldered parts may cause refrigerant to leak.
