11. Using hexagonal wrench, fully open both the
high pressure and low pressure valves.
12. Tighten valve caps on all three valves (service
port, high pressure, low pressure) by hand.
You may tighten it further using a torque
wrench if needed.
C
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.
11.3 Note on adding
refrigerant
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 7.5m (25’). In other areas, the
standard pipe length is 5m (16’). The refrigerant
should be charged from the service port on the
outdoor unit’s low pressure valve. The additional
refrigerant to be charged can be calculated using
the following formula:
Additional refrigerant per pipe length
Connective pipe
length (m)
Air purging
method
Additional refrigerant
≤ Standard pipe length Vacuum pump N/A
> Standard pipe length Vacuum pump
Liquid side: Ø 6.35 (ø 0.25”)
R32:
(Pipe length – standard length) x 12g/m
(Pipe length – standard length) x 0.13oZ/ft
R290:
(Pipe length – standard length) x 10g/m
(Pipe length – standard length) x 0.10oZ/ft
R410A:
(Pipe length – standard length) x 15g/m
(Pipe length – standard length) x 0.16oZ/ft
R22:
(Pipe length – standard length) x 20g/m
(Pipe length – standard length) x 0.21oZ/ft
Liquid side: Ø 9.52 (ø 0.375”)
R32:
(Pipe length – standard length) x 24g/m
(Pipe length – standard length) x 0.26oZ/ft
R290:
(Pipe length – standard length) x 18g/m
(Pipe length – standard length) x 0.19oZ/ft
R410A:
(Pipe length – standard length) x 30g/m
(Pipe length – standard length) x 0.32oZ/ft
R22:
(Pipe length – standard length) x 40g/m
(Pipe length – standard length) x 0.42oZ/ft
For R290 refrigerant unit, the total amount
of refrigerant to be charged is no more than:
387g(<=9000Btu/h), 447g(>9000Btu/h and
<=12000Btu/h), 547g(>12000Btu/h and
<=18000Btu/h), 632g(>18000Btu/h and
<=24000Btu/h).

Warning:
Do not mix refrigerant
types.
