Installation introduction
Connecting the tank unit
a) Shape the pipes according to the path;
b) Remove the threaded brass flare nuts(A) on the tank unit and store them
(check that no impurities are left);
c) Cut the pipe to the fixed length, with a pipe cutter, avoiding any deformation;
d) Remove burrs with pipe reamer avoiding to get impurities inside (keep down
the tube);
e) Insert the threaded brass flare nuts(A) on the pipes in the correct direction;
f ) Insert the tube into the flaring tool and make the flange at the end of the
connecting pipe, as indicated in the table.
Pipe(not supplied)
Inlet refrigerant pipe
Outlet refrigerant pipe
After confirming that there are no wrinkles or tears on the flare, connect the
pipes using two spanners, being careful not to damage the pipes. If the force is
insufficient, then there will be leaks. Although the force is excessive, there may
be losses because it is easy to damage the flange. The safest method is to
tighten the connection by using a spanner and a torque wrench.
