  • Page 3 IMPORTANT NOTICE ● HITACHI pursues a policy of continuing improvement in design and performance of products. The right is therefore reserved to vary specifications without notice. ● HITACHI cannot anticipate every possible circumstance that might involve a potential hazard. ● This heat pump air conditioner is designed for standard air conditioning only. Do not use this heat pump air conditioner for other purpose such as drying clothes, refrigerating foods or for any other cooling or heating process. ● Do not install the unit in the following places. It may cause a fire, deformation, corrosion or failure. * where oil vapor or oil is dispersed (including machinery oil). * where a lot of sulfide gas drifts such as at hot spring. * where inflammable gas may be generated or flowed. * where strong salty wind blows such as coast regions. * with an atmosphere of acidity or alkalinity. ● Do not install the unit in the place where silicon gas drifts. If the silicon gas attaches to the surface of heat exchanger, the fin surface repels water. Drain water splashes outside of the drain pan and splashed water runs inside of electrical box. It may cause water leakage or electrical devices failure. ● Pay attention to the following points when the unit is installed in a hospital or other facilities where electromagnetic wave is generated by a medical equipment. * Do not install the unit in the place where the electromagnetic wave is directly radiated to the electrical box, remote control cable or remote control switch. * Install the unit at least 3 meters away from electromagnetic wave radiators such as a radio. ● Do not install the unit in the place where animals and plants are exposed to the direct blowing air from the unit. It could adversely affect the animals and plants. ● The installer and system specialist shall comply with local regulations or standards for the safety.
