Application Information Outdoor Clearance If the condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area), sulphide gas (near hot spring, oil refinery plant), such as substances may lead to failure of the unit. The outdoor unit must be installed in such a way, so as to prevent short circuit of the hot discharged air or obstruction to the smooth air fl ow.

Application Information Refrigerant Piping Piping Length and Elevation When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends increases, system piping resistance to the refrigerant flow increases, thus lowering the cooling capacity, and as the result the compressor may become defective.
Application Information Additional Charge • The refrigerant gas is charged in the outdoor unit and, if the piping length is 7.5m, additional charge of the refrigerant after vacuuming is not necessary. • When the piping length is more than 7.5m, additional refrigerant charge (g) per additional 1m length as tabulated: Indoor FTN10/15P/QS...
