Liquid Side: Ø 6.35 (ø 0.25 in)
Inverter R410a:
(Pipe Length - SPL) x 20g/m
(Pipe Length - SPL) x 0.21oZ/ft
Liquid Side: Ø 9.52 (ø 0.375 in)
Inverter R410a:
(Pipe Length - SPL) x 30g/m
(Pipe Length - SPL) x 0.32oZ/ft
SPL = Standard Pipe Length
Note:
Open valve stems gently. When opening valve stems, turn the hexagonal wrench until it hits against
the stopper. Do not try to force the valve to open further.
Note:
Some systems require additional charging depending on pipe lengths. The standard pipe length
varies according to local regulations. For example, in North America, the standard pipe length is 7.5 m
(25 feet). In other areas, the standard pipe length is 5 m (16 feet). The additional refrigerant to be charged
can be calculated using the formula in the below chart.
