- remove the covers from the ends of the refrigerator lines and
tighten the fittings on the outdoor unit using two wrenches
to avoid warping the unit structure;
- Connect the vacuum pump to connectors (A) on the gas line
fittings;
- do not open the valves (the vacuum must be generated in
the refrigerator lines and indoor unit);
- generate vacuum conditions of up to 100 to 120 mmHg;
- On completion of the above operations and having finally
disconnected the vacuum pump, fully open the valves by
turning nuts (B) using a 4 mm male hex wrench;
- refit covers (C) and tighten;
- make the condensate drain connection;
- Carry out a final check, making sure that the lines are cor-
rectly positioned. Fix the refrigerator lines and electrical
