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 the following pages for 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 off 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.

PLEASE NOTE (only for 004U8044):

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 TDP-F, Type 004U8044), 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:

Start by shutting off all connections to the substation.

First follow the instructions for Fig. 1, 2 and 3 on page 16.

Then demount 3/4” plug in T-piece (pos. A), as illustrated in fig. 1.

Remove the existing capillary tube from pos. C to D. See fig. 2.

Demount bypass thermostat incl. 3/4” reducer bushing from pos. B. Unscrew 3/4” reducer bushing from bypass thermostat (the 3/4” reducer bushing is not to be reused). See fig. 3.

Mount bypass thermostat in pos A, as illustrated in fig. 4.
