connecting tube port and make sure that the port is clean.
5.4 After aligning the centre, turn the flare nut of the connection pipe to tighten the nut as
tight as possible by hand.
5.5 Use a spanner to hold the valve body and use a torque spanner to tighten the flare nut in
accordance with the values in the torque requirements table.
(Refer to the torque requirements table in the INSTALLATION PRECAUTIONS section).

6.1 Use a spanner to remove the protective plugs from the service port, the low pressure
valve and the high pressure valve of the outdoor unit.
6.2 Connect the pressure hose from the pressure gauge to the service port of the outdoor
unit's low pressure valve.
6.3 Connect the charge hose from the manifold pressure gauge to the vacuum pump.
6.4 Open the low pressure valve of the manifold gauge and close the high pressure valve.
6.5 Switch on the vacuum pump to empty the system.
6.6 The vacuum time must not be less than 15 minutes, or ensure that the compound pressure
gauge reads - 0.1 MPa (-76 cmHg).
6.7 Close the low pressure valve of the manifold pressure gauge and turn off the vacuum.
6.8 Hold the pressure for 5 minutes, make sure that the rebound of the composite gauge
indicator does not exceed 0.005 MPa.
6.9 Open the low pressure valve counterclockwise for ¼ turn with a hex spanner to let some
refrigerant fill the system, and close the low pressure valve after 5 seconds and quickly
remove the pressure hose.
6.10 Check all internal and external seals for leaks with soapy water or a leak detector.
6.11 Fully open the low pressure valve and the high pressure valve of the outdoor unit with a
hexagonal spanner.
6.12 Reinstall the protective caps on the service port, the low pressure valve and the high
pressure valve of the outdoor unit.
6.13 Reinstall the valve cover.
