The condenser unit is shipped with a predetermined factory charge level as shown below. For longer line sets greater than
15 ft. (Detail shown in tables on page 12) add 0.6 ounce of refrigerant per foot. Refer to the following page for the equivalent
length of the elbow fittings.

Additional charge (c)
= [for liquid line (c)-1] – [Adjust amount from suction line (c)-2]
(A) to (C) parameters are calculated/followed below.
(A) There is 2 way calculation for total refrigerant amount
(A)-1
Select line set length from (A)-1 table.
(A)-2
Calculate from above formula by using (B), (C)-1 and (C)-2 factors.
(B) Pick up from name plate which has factory charge amount.
(C) Calculate above formula. (C)-1 and (C)-2 shown below.
Subtract factory charge length (see (A)-1 Table) from the overall length and put the results in
ft.
Additional Charge for
