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. •... - Page 4 15. It is desirable that the amount of residual oil is less than 40 mg/10 m. Thickness of copper pipes used with R410A must be more than 0.6 mm. Never use copper pipes thinner than 0.6 mm. 16. During installation, before run the compressor, confirm the refrigerant pipes are fixed. Operation of compressor without fixing the piping, setting the valves at open condition, a burst may occur and cause injury.
