The recommended way to change refrigerants involves making a new list of 5
refrigerants, and change all five of them in the same session. Example: If only R-22
needs to be changed to R-1234yf (and if using USA defaults), program the following
items: R-410A, R-1234yf, R-404A, R-134a and R-407A.
1. At Main Screen [FIG.1] press and hold [MODE] until “PrO” (Program) Screen
[FIG.18] appears. “PrO” will blink.
2. Press and hold [SET] to enter the Refrigerant Selection Screen [FIG.19].
