- Page 6 ● Do not perform installation work, refrigerant piping work, condensate pump, or condensate piping and electrical wiring connection without referring to the installation manual. If the instructions are not followed, it may result in a water leakage, electric shock or a fire ● Use the specified non-flammable refrigerant (R410A) for the outdoor unit in the refrigerant cycle. Charge only R410A into the unit. Do not charge other materials into the unit such as hydrocarbon refrigerants (propane), oxygen, flammable gases (acetylene) or poisonous gases when installing, maintaining and moving the unit. These flammables are extremely dangerous and may cause an explosion, a fire, or injury. As originally manufactured, this unit contains refrigerant installed by Hisense/HITACHI. Hisense/ HITACHI uses only refrigerants that have been approved for use in the unit’s intended country or market. Hisense/HITACHI’s distributors similarly are only authorized to provide refrigerants that have been approved for use in the countries or markets they serve. The refrigerant used in this unit is identified on the unit’s faceplate and/or in the associated manuals. Any additions of refrigerant into this unit must comply with the country’s requirements with regard to refrigerant use and should be obtained from Hisense/HITACHI distributors.
