Additional charge
The units require additional charging of refrigerant, according to the
length of pipe connected at the size.
The correct amount of refrigerant to charge ’G’ (kg) can be lound by
using the following formulas (If G<O: no addition is required).
1. Pair system
L1 (m) One way length of liquid pipe
RP200 G = (L1-30) 0.06
RP250 G = (L1-30) 0.09
Allowable pipe length
See the table below concerning lengths and heights. Refer to the figures. Assume that the longest line in the figure corresponds with the actual
longest pipe, and the highest unit in the figure corresponds with the actual highest unit.
Maximum allowable pipe length (figures between
parenthesis represent equivalent length)
Pair L1 50m (70m)
Maximum height between indoor and outdoor All H1 30m
