Charging
■
Each outdoor unit is factory charged (nameplate charge) for the evaporator as well as a 7.5m(25ft)
line set. Any time a line set is used either shorter or longer then the nominal 7.5m(25ft) line set
length the refrigerant charge has to be adjusted.
■
Whether the line set is made shorter or longer you must adjust the charge based on how many ft of
tubing are either added or removed based on 30g(0.32oz) of R-410A per meter(foot).
Example: A 30ft line set is used
5 additional ft X 0.22 ounce per foot= add 1.1 ounces of R-410A
Important:
If you are ever uncertain of the unit charge, reclaim, evacuate and weigh in the correct charge using the
unit nameplate charge adjusting for line sets longer or shorter than 7.5m(25ft).
Confirm the refrigerant R-410A. Use manifold gauge and hose for R-410A.
