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 18. For R410A models, when connecting the piping, do not use any existing (R22) pipes and flare nuts. Using such same may cause abnormally high pressure in the refrigeration cycle (piping), and possibly result in explosion and injury. Use only R410A materials.
