Notes
(a) No additional charge of the refrigerant is needed when the pipe length is less than 10m(32.81ft), if the pipe
length is longer than 10m(32.81ft), additional charge of the refrigerant is needed according to the table.
(b)
Example: If 16kW model is installed at a distance of 25m (82.02ft), (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 5-7m(16.40-22.97ft) when the location of outdoor
unit is higher than indoor unit.
