3. Pipe network:
Refrigerant pipes made of seamless drawn copper from Cu-DHP, strength R220 soft according to
EN 12735-1, cleaned inside, pipe ends sealed, with factory-fitted thermal insulation made of
modified polyethylene according to DIN EN 14313 with structured white protective film. Building
material class flame retardant CL s1 d0 according to DIN EN 13501-1, does not drip when burning,
minimal smoke development. Permissible operating pressure 169 bar with 3-fold safety up to 100 °C
according to EN 14276.
Installation of pipes in accordance with DIN EN 378-2 and DKI i.164, copper pipes in refrigeration
and air conditioning technology. Brazing using silver or phosphorus solders in a protective gas
atmosphere. Pressing with special press fittings for refrigerant-carrying pipes in accordance with
DIN EN ISO 14903.

Brazing is carried out using brazing alloys in accordance with DIN EN ISO 17672, recommended
brazing alloys CuP 179 or CuP 279, if necessary, fluxes in accordance with DIN EN 1045 type
FH10 must be used. For solders AG 134, AG 145, and AG 244, use flux in accordance with DIN
EN 1045. Type: FH 10. Brazed joints may only be made by qualified personnel. Before and during
the joining process by brazing or welding, the pipes must be flushed with dry protective gases, e.g.,
inert gases (noble gases, nitrogen, and mixtures thereof) or forming gases (e.g., nitrogen-hydrogen,
nitrogen-argon, etc., max. hydrogen content 4 vol.%). When using capillary solder and press fittings,
consult the respective fitting manufacturer regarding the possible areas of application, particularly
the maximum permissible operating pressures.
Pipe network consisting of following components:
