Safety Instructions Special Precautions DANGER When Wiring Electrical shock can cause severe personal injury or death. Only a qualified, experienced electrician should attempt to wire this system. ● Do not supply power to the unit until all wiring and tubing are completed or recon- nected and checked.
Page 13
Safety Instructions DANGER ► Keep the fire alarm and the air outlet at least 1.5 m away from the unit. In moist or uneven locations Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit.
Page 14
Safety Instructions When Connecting Refrigerant Tubing DANGER ● When performing piping work, do not mix air except for specified refrigerant (R410A or R32, depending on the outdoor unit model) in refrigeration cycle. It causes capacity down, and risk of explosion and injury due to high tension inside the refrigerant cycle.

Safety Instructions Check of Density Limit U-100PZH2E5 The refrigerant (R32), which is used in the air conditioner, is a flammable refrigerant. So the requirements for installation space of appliance are determined according to the refrigerant charge amount [mc] used in the appliance. The minimum indoor floor space compared with the amount of refrigerant is roughly as follows, in case it is installed in a living area: PAW-VP200LDHW, PAW-VP500LDHW must be calculated as wall mounted.
