1-8. Additional Refrigerant Charge

Additional refrigerant charge amount is calculated from the liquid tubing total length as follows.
Required amount of additional refrigerant charge = [ (Amount of additional refrigerant charge per meter of each size of liquid tube × its tube
length) + (...) + (...)] + [(Necessary amount of additional refrigerant charge per

* When bending the tubes, use a bending radius that is
at least 4 times the outer diameter of the tubes.
In addition, take sufficient care to avoid crushing or
damaging the tubes when bending them.
