▪ Domestic hot water tank – Standstills. In cases where during longer periods of
time there is no consumption of hot water, the equipment MUST be flushed with
fresh water before usage.
▪ Domestic hot water tank – Disinfection. For the disinfection function of the
domestic hot water tank, see "7.4.5 DHW pump for disinfection" [4 53] and
"Domestic hot water control: advanced"[4144].
▪ Domestic hot water tank – installation of third-party tank
For a third-party tank, the maximum tank set point is 60°C.
See the installation manual of the domestic hot water tank for more information.
▪ Domestic hot water tank – installation of third-party tank with dedicated tank
specifications
The dedicated tank specifications are:
- coil size is ≥1.05m
2
,
- a sensor pocket is foreseen above the heating coil. The tank sensor should not
be in contact with water.
If the third-party tank has at least the same specifications of a dedicated tank,
the domestic hot water setting [E-07] can be changed to 0. This allows for a
temperature setpoint higher than 60°C and for the heat pump to heat up the
tank. See "Quick wizard: Options"[4130].
▪ Thermostatic mixing valves. In accordance with the applicable legislation, it may
be necessary to install thermostatic mixing valves.
▪ Hygienic measures. The installation must be in compliance with the applicable
legislation and may require additional hygienic installation measures.
▪ Recirculation pump. In accordance with the applicable legislation, it may be
required to connect a recirculation pump in between the hot water end point
and the recirculation connection of the domestic hot water tank.

8.3.3 Formula to calculate the expansion vessel pre-pressure
The pre-pressure (Pg) of the vessel depends on the installation height difference
(H). For more information on the formula, see the manual of the third-party
expansion vessel.
8.3.4 To check the water volume and flow rate
Minimum water volume
Check that the total water volume in the installation is minimum 20 litre, the
internal water volume of the outdoor unit NOT included.
INFORMATION
In critical processes, or in rooms with a high heat load, extra water might be
required.
