Specification texts: Wilo-RainSystem AF Comfort MC 304 Automatic rainwater utilisation and drinking water replenishment system as compact module for single-family houses made up of quiet, self-priming, multistage horizontal high-pressure centrifugal pumps with hydraulic suction tract as well as 11 litre replenishment reservoir with replenishment of drinking water as needed when the rainwater storage tank is not full. All parts that come into contact with the fluid are corrosion-proof. Commissioning with basic parameters set at the works (plug & play) by electronic control RainControl Economy (RCE), pump operation time-dependent water exchange of the replenishment reservoir, calcination protection of the solenoid valve, built-in dry-running protection system for the pump, filling level display, connection for backflow warning or replenishment reservoir overflow transmitter, permanent operational data acquisition, energy saving mode function, operating state protocol, user-friendly menu-guided operating options via configurable LC display, as well as built-in logic for suction aid. The system is mounted on a plastic-foam support. Ready for connection with 3 m cable and shock-proof plug incl. fastening material for front wall mounting, as well as cover cap made of recyclable EPP. Optional: replenishment reservoir overflow transmitter. The system meets the newest requirements of DIN1989. Consulting guide: The suction line must be laid in an uninterrupted rise from the rainwater storage tank to the AF system. A clearance of at least 200 mm is to be provided for above the system for correction purposes. A clearance of at least 100 mm should be provided for to the left of the system in order to ensure ventilation of the pump motor. The overflow is connected underneath the system. The connections for the fresh water metering as well as the suction and pressure pipes are located on the right side of the system. Motor protection: Integrated motor protection switch System control: Rain Control Economy (RCE) fully electronic control unit for controlling a rainwater pump, control via pressure transmitter 4-20 ma Filling level monitor: Float switch with 20 m cable (in the rainwater storage tank) Storage tank: Volume: 11 l Material: PE, black, opaque Connections: Pressure side: Screwed connection, Rp1 Suction side: R1 Inlet: Fresh water replenishment via R ¾ float valvewith free outlet according to DIN EN 1717 Overflow: 105 x 65 via supplied funnel to DN 70 System protection class: Switchgear: IP 54 Pumps: IP 54 Dimensions (W x H x D): 660 x 638 x 393 mm Materials Pump housing: 1.4301 Pump shaft: 1.4057 [AISI431] Mechanical seal: Carbon/ceramic Stage chambers: Noryl Approved fluids (other fluids on request) Pure water without settling sediment: Rainwater: Output Max. suction head: 8 m Inlet pressure Max.: 1 bar Fluid temperature: +5...+35 C Max. ambient temperature: 40 C Subject to change without prior notice. www.wilo.co.uk 50 Hz 2015-02 4 / 5
