IF ADDITIONAL REFRIGERANT IS REQUIRED
„ „
When the piping is longer than pre-charge length, additional charging is necessary. •
For the additional amount, see the table below. •

The additional charging amount for twin / triple type will be calculated as follows.
Additional charging amount (g)
= (A x 100) + (B x 50) + (C x 30) - 1,500
A = Piping length (m) of liquid pipe [12.70 mm (1/2 in.)] •
B = Piping length (m) of liquid pipe [9.52 mm (3/8 in.)] •
C = Piping length (m) of liquid pipe [6.35 mm (1/4 in.)] •
Do not remove refrigerant, even if the additional amount calculated is negative. •
