9.3 COOLING CIRCUIT INSTALLATION
9.3.1 COOLING CIRCUIT INSTALLATION PRECAUTIONS
In order to correctly implement the cooling circuit, the following precautions need to be complied with:
• Do not leave the circuit outdoors for an extended time, to prevent excessive formation of humidity.
• To prevent copper dust or swarf from getting into the system, the pipes should be cut using a pipe cutter rather than
a hacksaw.
• It is necessary to carefully clean the pipe endings using the specic pipe reamer.
• If the ends are to be soldered, they should be cleaned with grade 00 sandpaper to eliminate all oxidisation and dirt.
• To avoid the curvature radius being too narrow or attening the piping, bend the pipes with a suitable pipe bender
of sucient diameter.
• Prepare the end part of the piping to house the part to be tted, widen the diameter with a suitable expander for
copper pipes of sucient diameter.
• Welding must be carried out through capillary brazing with oxyacetylene welding torch. The welding alloy must be
copper or a copper-silver alloy.
• During welding protect the components with a damp cloth to prevent overheating.
9.4 UNIT COOLING PIPE CONNECTION
The refrigerant inlet and outlet connections on the unit can be identied by their adhesive labels. To facilitate connection
inside the unit, there is a section of pipe approximately 200 mm long, with relative cock, crimped and welded shut on the free end.
