For the quantity of brackets to apply on the refrigerati-
on connecting lines of the remote unit
see
table 6
.
Hermetic welding (Fig.10).
Creation of vacuum (0.03mBar) in the connection
pipes (delivery and suction). Unless otherwise speci-
fied, the condensing unit is charged with freon.
Check vacuum seal of pipes.
Opening of cut-off bibcocks on condensing unit.
Check for leaks.
Check of exact gas charge via the liquid flow indicator
located on the condensing unit.
Checking the condensation water circulation and
pressure (system with water condensation).
