Akva Lux II TDv
If the household plumbing system includes hot water recirculation
the substation must be connected to the hot water recirculation
system.
Circulation set is not included in the delivery and must be ordered
separately.
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 pages 10 to 12 for information about preparation
of substation for and connection to the DHW recirculation system.
Remember always to mount circulation pump and 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 water heater.
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 unit) is switched off for a longer
period, it is to be recommended that the Danfoss FJVR thermostat
is closed during the same period.
