Circulation set for S-F units
Zirkulationsset für S-F Stationen
Div.788 Code No. 004U8400
Div.789 Code No. 004U8401
English - GB
If the household plumbing system includes hot water recirculation the substation must be connected to the hot water recirculation system
by using this circulation set.
It is to be recommended to prepare the substation for recirculation BEFORE 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 DHW recirculation system.
Remember always to mount circulation pump, non-return valve on the circulation pipe and to mount safety valve on the DCW 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 o for a longer period, it is to be recommended that the Danfoss bypass thermostat is closed during the same period.

NOTE!
Please note that substations with Danfoss AVE expanion unit must not be used on systems with DHW recirculation.
German - DE
Wenn eine Zirkulationsleitung in der Hausinstallation vorhanden ist, ist die Station an die Zirkulationsleitung anzuschließen, und eine
Umrüstung von Bypassbetrieb auf TWW-Zirkulation ist mittels dieses Zirkulationssatzes vorzunehmen.
Es wird empfohlen die Station für TWW-Zirkulation VOR der Montage auf der Wand vorzubereiten.
Die 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.
Bitte einbau von Umwälzpumpe und Rückschlagventil in der Zirkulationsleitung beachten und Sicherheitsventil in der Kaltwasserzuleitung einzubauen. Die 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 Danfoss
Bypass Thermostat im gleichen Zeitraum geschlossen wird.
BITTE BEMERKEN!
Der AVE Druckausgleichventil ist nicht auf Systemen mit TWW-Zirkulation zu verwenden.

PLEASE NOTE (only for 004U8543):
For systems with DHW 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 (Akva 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 o all connections to the substation.
2.
First follow the instructions for Fig. 1, 2 and 3 on page 15.

reducer bushing is not to be reused). See g. 3.
6.
Mount bypass thermostat in pos A, as illustrated in g. 4.
7.
Plug the hole in pos. B with 3/4” plug (from pos A) and gasket, as
illustrated in g. 5.
