The precautionary points indicated herein are divided under two headings: WARNING and CAUTION those points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the WARNING section.
  • Page 113 INSTRUCTIONS TO INSTALLATION PRECAUTION Execute proper grounding. Do not connect the earth wire to a gas pipe, water pipe, lightening rod, or a telephone ground wire. Improper placement of earth wires can result in electric shock. An electric leakage breaker must be installed, otherwise electric shock or other accidents would occur.
  • Page 114 INSTRUCTIONS TO INSTALLATION WARNING BE SURE TO READ THESE INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD CAUSE SERIOUS INJURY OR DEATH, EQUIPMENT MALFUNCTION AND/OR PROPERTY DAMAGE.
