| INSTALL THE OUTDOOR UNIT
• Install the connection tube
i. Align the center of the tubing flare with the
relevant valve.
2. Screw in the flare nut by hand and then tighten
the nut with spanner and torque wrench. See
the table below for the correct torque.

Install the connecting tubes of the
indoor/outdoor unit.
DO NOT OPEN THE GAS VALVES UNTIL THE
EVACUATION PROCESSIS COMPLETE.
Remove the gas line service port cap and
connect the gas valves of the vacuum gauge,
vacuum pump and outdoor unit.
NOTE: Connect bg using a 1/4" Female x
1/2" Male Adapter Access Fitting (obtain Iocallg).
Start the vacuum pump. (Running time should
be more than 15 minutes.)
Check the vacuum with the vacuum gauge. The
gauge should read -30 in. Hg. After evacuation,
fulls close the handle on the manifold valve
(on the vacuum pump device). Then stop the
vacuum pump and disconnect it.
6. The pressure should be kept for 1-2 minutes
to confirm that the reading of the vacuum
gauge does not change. The pressure should
be-30 in. Hg.
7. Remove the vacuum line and replace the service
port cap.
8. Remove both the liquid and gas valve caps.
9. Open the gas and liquid valve entirelg, using
the 5 mm Allen wrench. If this is not done, the
performance will be reduced, or an error will
OCCUr.
i0. Replace the caps and tighten securelg.
