It is to be recommended to prepare the substation for recirculation EFORE mounting it on the wall. The recirculation pipe in your household plumbing system must be connected to a nipple, mounted on the circulation pipe of the substation. - See following pages information about preparation of substation for and connection to the HW recirculation system. Remember always to mount circulation pump, non-return valve on the circulation pipe and to mount safety valve on the CW inlet. The pump must be installed so that the pump is pumping water towards the substation. If a time-controlled pump is used, it is to be recommended that the circulation water temperature is set to approx. 35 C. If the circulation pump (outside the substation) is switched off for a longer period, it is to be recommended that the anfoss bypass thermostat is closed during the same period. NOTE! Please note that substations with anfoss VE expanion unit must not be used on systems with HW recirculation. German - E Wenn eine Zirkulationsleitung in der Hausinstallation vorhanden ist, ist die Station an die Zirkulationsleitung anzuschließen, und eine Umrüstung von ypassbetrieb auf TWW-Zirkulation ist mittels dieses Zirkulationssatzes vorzunehmen. Es wird empfohlen die Station für TWW-Zirkulation VOR der Montage auf der Wand vorzubereiten. ie Zirkulationsleitung der Hausinstallation ist an einen Messing-Nippel, den auf dem Zirkulationsschlauch der Station montieret ist, anzuschliessen. - Siehe folgende Seiten für weitere Informationen über Zirkulationsanschluss. itte einbau von Umwälzpumpe und Rückschlagventil in der Zirkulationsleitung beachten und Sicherheitsventil in der Kaltwasserzuleitung einzubauen. ie Fleißrichtung der Pumpe ist in Richtung Station. Wird die Umwälzpumpe über eine Schaltuhr gesteuert, empfehlen wir, dass die Zirkulationswassertemperatur auf ungefähr. 35 C eingestellt wird. Wenn die Umwälzpumpe (außerhalb der Station) für einen längeren Zeitraum abgeschaltet wird, wird es empfohlen, dass der anfoss ypass Thermostat im gleichen Zeitraum geschlossen wird. ITTE EMERKEN! er VE ruckausgleichventil ist nicht auf Systemen mit TWW-Zirkulation zu verwenden. anfoss istrict Energy VI.IE.1.5 KHR 1

4 Installation Guide PLESE NOTE (only for 004U8543): For systems with HW recirculation the bypass thermostat must alway be installed before the heat meter. On substations, that are supplied with bypass thermostat mounted after the heat meter (kva Lux II S-F, Type 004U8543), the bypass thermostat must therefore be relocated before the substation is prepared for recirculation, - i.e. the bypass thermostat must be mounted before the heat meter. Please follow the below instructions: 1. Start by shutting off all connections to the substation. 2. First follow the instructions for, 2 and 3 on page 15. C 3. Then demount 3/4 plug in T-piece (pos. ), as illustrated in fig Remove the existing capillary tube from pos. C to. See fig emount bypass thermostat incl. 3/4 reducer bushing from pos..
