Resideo Refill Combination NK300SE-VE with Demineralization Cartridge, R 1/2

Resideo Filling Combination NK300SE-VE
The filling combination consists of the following components, viewed in the direction of flow: shut-off valve, backflow preventer BA, pressure reducer with manometer connection, shut-off valve (NK300S-1/2A), blending unit (VE300S-1/2A) with demineralization cartridge (P300-LES), test and drain valve, and a shut-off valve. Thanks to the combination of the backflow preventer BA, heating systems with inhibitors (fluid category 4), for example, can be refilled safely according to DIN EN 1717 in conjunction with DIN 1988-100. The desired pressure of the downstream system can be set at the pressure reducer. The filling unit simplifies water demineralization and thus effectively prevents corrosion in, for example, heating systems. A drain valve allows for sample collection to check parameters. The filling unit has a removable electronic smart monitoring system. The electronic user interface has the following functions: input of data for water hardness and cartridge type, display of flow rate, water consumption, and remaining cartridge capacity, alarm function as a reminder to replace the cartridge, alarm function as a reminder to replace the battery (batteries included), visualization 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 installed without tools. Also included in the scope of delivery is a measuring kit for determining raw water hardness and a mounting set with 2 screws and 2 dowels.
