b Additional refrigerant amount charged in the
field(Refer to the above information for the
quantity of refrigerant replenishment.)
c Total refrigerant charge

CAUTION
• The filled-out label must be adhered in the proximity
of the product charging port (e.g. onto the inside of
the stop valve cover).
• Make sure that the total refrigerant charge does not
exceed (A), the maximum refrigerant charge, which
is calculated in the following formula: Maximum
refrigerant charge (A) = factory refrigerant charge
(B) + maximum additional refrigerant charge due to
piping extension (C).
