R996T-5 pipes are extruded, in compliance with EN ISO

21003 Standards, with an intermediate (within the thickness

of the pipe) anti-oxygen barrier in EVOH, to avoid any type of damage on site and therefore the modest oxygen quantity that permeates from outside towards the inside of the pipe, becomes quite negligible.

• The connection to distribution manifolds and to the system terminals shall be made by means of Giacomini’s adaptors for synthetic pipes.
• In order to make a correct connection, it is essential to cut off the pipes with tools that can make a clean cut without deburring and perpendicular to its axis.
• During the pipe laying operations, it is necessary making curvatures with a minimum radius equal to five times the external diameter of the pipe itself. After the pipe laying, it is opportune making a pressure test of the system, in order to underline immediately possible fluid losses.
• In case of radiant panel systems, the laying of the pipe covering shall occur with care, by paying attention not to scratch the pipes with spatulas or crush them in the passages with wheel barrow.
• The pipes must not remain exposed for long time to the sun radiations or to fluorescent lamps. Keep the coils that are not used in the suitable boxes, to avoid that the ultraviolet rays will alter the chemical and physical features.
• In case of radiant panel systems, it is good to lay over the pipes a foundation of 3 cm at least, to avoid cracks due to thermal expansion.
• While crossing possible expansion joints, it is important to protect the pipe with a protecting covering in order to avoid excessive mechanical stress.  Precautions The use of R996T-5 pipes requires the observance of some prescriptions, needed to guarantee the life time and the functional character.
• Store the pipes in the appropriate packaging, by avoiding their direct exposition to sun rays, and in covered and dry places to prevent damages to the boxes caused by the humidity.
• Prevent the pipes from coming into contact with sharp bodies able to scratch and trigger carving phenomenon – pay particular care during the installation and transport phases.
• Prevent icing inside the pipes and in the packaging, because the expansions due to the state change could cause cracking.
• Prevent the pipe from coming into contact with open flames or other heat sources, that could provoke melting, even partial.
• If a fixing to electrically welded networks is needed, use plastic material instead of metallic bands, to avoid damages to the pipes.
• Prevent the contact with chemical solvents or paints that can damage the pipes.  Warranty The guarantee is not valid in the following cases: 1) if the working conditions are different from those prescribed; 2) if the pipes are used to distribute fluids, that are not compatible with the material; 3) if the installation instructions are not scrupulously followed 4) if at the installation time, during the laying phase or at the pressure testing of the system, the pipe shows visually perceivable defects caused by accidental factors; 5) if the pipe is installed by using components not produced by Giacomini S.p.A., or in any case different from the permitted ones.
