Warning:
All work must be performed, components selected and materials used in complete accordance with the legislation in force
in material in the country concerned, and considering the operating conditions and intended uses of the system, by qualified personnel.
The diameter of connecting pipes between the conditioner and condensing unit must be respected, otherwise the guarantee becomes
invalid. Always use large radius curve (bending radius at least equal to pipe diameter)
NOTE:
The diameter of the refrigerant lines between the air-conditioner and the remote condenser (OD) must be chosen according to
the length of the lines, and therefore this will not always coincide with the inside diameter of the joint to be welded supplied by the manu-
facturer. Special care must be paid to the insulation of the hot gas pipes under the raised floor.
RECOMMENDED OUTSIDE DIAMETERS OF THE LINES (for equivalent lengths up to 50 m)
Equivalents lenght in meters of: curve, shut-off and non-return valve
