Check The Additional Amount Of Refrigerant - Toshiba MMY-MUP0801HT8JP Service Manual

• Check the additional amount of refrigerant.

Checklist 2
Calculate total additional amount refrigerant from the compensation amount of refrigerant according to total
outdoor unit horsepower (A), the additional amount of refrigerant by the pipe diameter on the liquid side and
the pipe length (B),the compensation amount of refrigerant according to indoor unit horsepower (C), and the
total compensation amount of refrigerant according to the system diversity (D)
Additional amount
=
of refrigerant according to total outdoor unit horsepower
+
First, refer to following table below, calculate the the compensation amount of refrigerant according to total
outdoor unit horsepower (A)
