Resideo refill combination NK300SE-VEThe refill combination consists of the following components when viewed in the direction of flow: Shut-off device, system separator BA, pressure reducer with pressure gauge connection, shut-off device (NK300S-1/2A), blending unit (VE300S-1/2A) with demineralisation cartridge (P300-LES), test and drain device and a shut-off device. By combining the BA system separator, heating systems with inhibitors (fluid category 4), for example, can be refilled safely in accordance with DIN EN 1717 in conjunction with DIN 1988-100. The desired pressure of the downstream system can be set on the pressure reducer. The refill unit simplifies the demineralisation of water and thus effectively prevents corrosion in e.g. heating systems. A drain valve enables sampling to check the parameters. The refill unit has a removable electronic smart monitoring system. The electronic user interface has the following functions: Input of data on water hardness and cartridge type, display of volume flow, water consumption and remaining cartridge capacity, alarm function as an indication to replace the cartridge, alarm function as an indication to replace the battery (batteries included), visualisation of alarms on the display, audible alarm (can be manually muted or deactivated). The housing is made of dezincification-resistant brass. The cartridge is included in the scope of delivery and can be fitted without tools. The scope of delivery also includes a measuring set for determining the raw water hardness and a fixing set with 2 screws and 2 plugs.Medium: drinking waterInstallation position: horizontal with drain connection facing downwardsPower supply: 2 AA alkaline batteries (not inserted in the device)Kvs value: 0.3 m3/hDesign: With threaded nozzles 1/2"Back pressure: 1.5 bar - 4 barConnections: Male threadMax.
