Notes
(a) No additional charge of the refrigerant is need when the pipe length is less than 10m, if the pipe length is
longer than 10m, additional charge of the refrigerant is needed according to the table.
(b) Example: If 14kW model is installed at a distance of 25m, (25-10)x50=750g refrigerant should be added
.
Rated capacity is based on standard pipe length and maximum allowable length is based on the product
reliability in the operation. Oil trap should be installed every 5-7 meters when the location of outdoor unit is
higher than indoor unit.
