Page 3: Safety Precautions
Safety Precautions Read carefully this "SAFETY PRECAUTIONS" to ensure a proper operation of the system. There are four kinds of precautions and suggestions as follows: Warning:An improper handing could lead to grave result like a death, serious injury, etc. Caution:An improper handing could lead to injury or malfunction; a very serious problem could occur depending on situation. - Page 4 Safety Precautions WARNING Neither stand on the air conditioner nor place Do not wash the air conditioner with water. something on it. It could cause electric shocks. There are risks of falling or injury by collapsed object. Execute proper grounding. Ground wires should never connect to a gas pipe, city water pipe, lightning conductor rod or ground wire of the telephone.
- Page 5 Safety Precautions The following instructions should be followed when installing your new refrigerant air conditioner. This air conditioner uses environmentally friendly refrigerant (R407C). 1.R407C refrigerant requires a higher system pressure and is more likely to be affected by moisture, oxides and grease. If polyol ester is used, special care should be taken to avoid contamination from moisture, dust, refrigerant as well as refrigeration oil in the cooling system.
