Page 3: Safety Precautions
1. Safety Precautions Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing. Electrical work must be installed or serviced by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit for the model installed. The caution items stated here must be followed because these important contents are related to safety. - Page 4 WARNING 19. During installation, install the refrigerant piping properly before run the compressor. (Operation of compressor without fixing refrigeration piping and valves at opened condition will caused suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc). 20.
