the technical handover of equipment by REMKO (also for A2L refrigerants in accordance with

DIN EN 60335-2).

- The contractor must announce all necessary power requirements for CTS pre-installation.

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:
