2. SAFETY CONSIDERATION 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 peference. Improper installation of equipment or accessories may result in electric shock, short-circuit, leakage, fire or other damage to the equipment. - Page 8 WARNING Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repair requiring the assistance of other skilled personnel shall be carried out under the supervision of the person competent in the use of flammable refrigerants. Tear apart and throw away plastic packaging bags so that children will not play with them.Children that playing with plastic bags face danger of death by suffocation.
