- The cooling pipe used in the installation must be copper suitable for its use in cooling circuits.

- Before ﬁ lling with refrigerant, cleaned dehydration and deoxidized of the entire refri-

gerant circuit must be done.

- Both ends of the batteries (sealed points) must be cut before being welded to the re-

frigeration installation pipe.

- The circuit must be equipped with all the necessary components to ensure functiona-

lity and proper functioning of the entire DX system (compressor, condenser, expansion

valve operation control kit, ﬁ lter, desiccant, etc...).

In order to ensure oil return to the compressor, it is recommended to design the suction and

gas lines, such that ﬂ ow speeds of 2,6 m/s (horizontal pipes) and 5,2 m/s (vertical pipes)

will be achieved.

-$/. DRAINAGE SYSTEM

• A siphon must be installed with pressure head difference in mmWG greater than the

pressure provided by the fan, to facilitate draining condensate from the tray.

• The drainage system should have a minimum slope of 2%.

-$'&. ELECTRICAL CONNECTION

• The unit installation must be done by a qualiﬁ ed professional.

• Before putting the unit in place, make sure that the nominal supply voltage mat-

ches that listed on the unit’s identification plate.

• It should be installed with cables whose cross-section meets current regulations

and prevents overheating and voltage drops that exceed permissible limits. Cu-

rrent regulations must be obeyed, and the designer’s instructions must be fo-

llowed at all times.

• Before connecting the cables, make sure that the electricity is turned off and that

there is no voltage present in any of them.
