Possible risks: ▪ Excessive refrigerant concentrations in a closed room can lead to oxygen deficiency. ▪ Toxic gas might be produced if refrigerant gas comes into contact with fire. WARNING ALWAYS recover the refrigerant.
Page 13 General safety precautions Then A siphon tube is NOT present Charge with the cylinder upside down. ▪ Open refrigerant cylinders slowly. ▪ Charge the refrigerant in liquid form. Adding it in gas form may prevent normal operation. CAUTION When the refrigerant charging procedure is done or when pausing, close the valve of the refrigerant tank immediately.
Page 14 General safety precautions WARNING ▪ ONLY use copper wires. ▪ Make sure the field wiring complies with the national wiring regulations. ▪ All field wiring MUST be performed in accordance with the wiring diagram supplied with the product. ▪ NEVER squeeze bundled cables and make sure they do NOT come in contact with the piping and sharp edges.
Page 15 General safety precautions Install power cables at least 1 meter away from televisions or radios to prevent interference. Depending on the radio waves, a distance of 1 meter may NOT be sufficient. NOTICE ONLY applicable if the power supply is three‑phase, and the compressor has an ON/ OFF starting method.
