Page 3: Safety Precautions
1. Safety Precautions Read the following “SAFETY PRECAUTIONS” carefully before installation. Electrical work must be installed by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit for the model to be installed. ... - Page 4 WARNING During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fixing refrigeration piping and valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc. During pump down operation, stop the compressor before remove the refrigeration piping.
