Installation height: max. 3.50 m above floor. 2. Air conditioning system, consisting of: Description: REMKO MVV 2003 DC Quantity: 1 each Manufacturer: Remko Model: MVV 2003 DC Item number: 1623680 Description: Floor console BK-1000 Plus S Quantity: 1 each Manufacturer: Remko Model: BK-1000 Plus S Item number: 1613273 Description: Condensate collection tray incl. oil separator MVV 2000/Duo Quantity: 1 each Manufacturer: Remko Model: MVV 2000/Duo Item number: 260128 Description: REMKO MVW 222 Quantity: 9 each Manufacturer: Remko Model: MVW 222 Item number: 1623504 Description: KFB-4 wired remote control Quantity: 9 each Manufacturer: Remko Model: MVD 222-1002/MVW 222-562 Item number: 1613269 - Fixed price for the refrigeration connection of indoor air conditioning units in connection with 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: Description: Refrigeration pipe, insulated, installed according to design. Quantity: according to design Manufacturer: Remko Model: 3/8”, 3/4”, 1/4”, 1/2”, Item number: 260128 Description: Y-distributor set for MVV AT/IT fluid and suction line Quantity: 2 sets Manufacturer: Remko Item number: 1611095 Description: 4-way distributor set for liquid gas and suction line Quantity: 2 sets Manufacturer: Remko Item number: 1611096 Description: Condensation hose 16/18 mm diameter, per meter Quantity: 1 each per wall unit Manufacturer: Remko Item number: 1613053 Description: Condensation pump KP-6 Quantity: 1 each per wall unit Manufacturer: Remko Item number: 1613251 The installation of the distribution sets involves connecting and soldering the refrigerant lines already connected by the installer to the distributors. Since absolute cleanliness must be ensured in this complex pipe system, soldering is carried out under dry nitrogen. 4. Miscellaneous / Additional services, special services: - The pipe dimensions must be checked by the contractor and adjusted if necessary. - The contractor must adjust the system components so that the planned functions and performance are achieved and the legal requirements are met. The air volume flows must be adjusted in accordance with the calculated settings. Measured values must be documented. - The contractor shall provide one-time training for the operating and maintenance personnel for the system. Leading time for coordination: 2 weeks. - If necessary, the delivery and installation of special fastening structures, e.g., brackets and support frames is also part of this contract. - Delivery of the operating materials and media required for commissioning and trial operation, particularly the required refrigerant R 410A. 5.
