The 07KD range covers 8 models: 010-015-018-024-028-036-048-060. The power supply is 230V/1ph/50Hz for 07KD 010 to 028 and 400V/3ph/50Hz for 07KD 036 to 060. The nominal cooling capacities are from 2,6 to 16 kW. The 07KD units are located indoor and should be selected versus an air-cooled system when the following conditions apply: · If outdoor installation is not possible: lack of space, critical sound power level, aggressive ambient atmosphere, distance between indoor and outdoor unit too great with difficult piping arrangements, problems in running the pipes supply to the outdoor unit, no clearance around air-cooled condenser, architectural, aesthetic problems, problematic service conditions. · If cooling water is available and is of good quality · If space is available in a machine room close to the airconditioned office. The table gives all combinations available with the water-cooled 07KD units, in the "Global-Split" system family. To connect the 07KD to any other unit, check with your local Carrier office or with qualified installers. Wrong combinations and control incompatibility can cause serious damage and may void the warranty. Inspect the shipment Inspect the unit for damage or missing parts. If damage is detected or if shipment is incomplete, immediately file a claim with the shipping company. Only remove the packaging at the final installation. Check that the electrical data on the nameplate corresponds with the installation network data. Check also that field power supply is sized for the unit and for additional accessories. Network voltage range: 198 to 264 V (230/1/50) for 07KD 010-028, 350 to 460 V for 07KD 036 to 060. Exceeding these limits will void the warranty. Safety instructions Installation, start up and service of the 07KD should be only done by trained qualified installers due to system pressure and electrical components. When working on equipment observe precautions in the literature, on tags, stickers and labels attached to equipment and any other safety precautions that apply. Follow all safety codes, wear safety glasses and work gloves; when brazing wear protection equipment and have a fire extinguisher ready. Note: Be sure power to unit and accessories is shut off before performing maintenance or service. Generalità Le unità 07KD sono unità condensanti per solo raffreddamento, utilizzate nei sistemi ad acqua Carrier, ma anche con unità ad espansione diretta con evaporatore e ventilatore, correttamente selezionate. La gamma 07KD comprende 8 modelli: 010015-018-024-028-036-048-060. L'alimentazione elettrica è 230V/1f/50Hz per le grandezze da 010 a 028, e 400V/3f/50Hz per le grandezze da 036 a 060. Le rese di raffreddamento nominali vanno da 2.6 a 16kW. Le unità 07KD situate all'interno dei locali sono da preferirsi ai sistemi raffreddati ad aria quando si verificano le seguenti condizioni: · Se l'installazione all'esterno non è possibile: mancanza di spazio, rumorosità critica, condizioni atmosferiche aggressive, distanza eccessiva ...
