NOTICE
When circulation in each or certain space heating loops is
controlled by remotely controlled valves, it is important that
the minimum flow rate is guaranteed, even if all valves are
closed. In case the minimum flow rate cannot be reached,
a flow error 7H will be generated (no heating or operation).
See the installer reference guide for more information.
See the recommended procedure as described in "8.2 Checklist
during commissioning"[432].
5.2 Connecting water piping
5.2.1 To connect the water piping
NOTICE
Do NOT use excessive force when connecting the field
piping and make sure the piping is aligned properly.
Deformation of the piping can cause malfunctioning of the
unit.
NOTICE
Do NOT use excessive force when connecting the piping.
Deformation of the piping can cause malfunctioning of the
unit.
1 Connect the O-rings and shut-off valves to the outdoor unit
water connection pipes of the indoor unit.
2 Connect the outdoor unit field piping to the shut-off valves.
3 Connect the O-rings and shut-off valves to the space heating/
cooling water pipes of the indoor unit.
4 Connect the space heating/cooling field piping of both zones to
the shut-off valves.
5 Connect the domestic hot water in and out pipes to the indoor
unit. It is obligatory to use the accessory G3 kit EKUHWG3D to
comply with UK legislation. See "5.2.2 To connect the water
piping for domestic hot water"[410].

NOTICE
It is recommended to install shut-off valves to domestic
cold water in and domestic hot water out connections.
These shut-off valves are field supplied.
NOTICE
Overpressure bypass valve (delivered as accessory). We
recommend to install the overpressure bypass valve in the
space heating water circuit.
▪ Mind the minimum water volume when choosing the
installation location of the overpressure bypass valve
(at the indoor unit, or at the collector). See "5.1.1 To
check the water volume and flow rate"[49].
▪ Mind the minimum flow rate when adjusting the
overpressure bypass valve setting. See "5.1.1 To
check the water volume and flow rate" [4 9] and
"8.2.1To check the minimum flow rate"[432].
NOTICE
Install air purge valves at all local high points.
NOTICE
A pressure relief valve (field supply) with an opening
pressure of maximum 10 bar (=1 MPa) must be installed
on the domestic cold water inlet connection in accordance
with the applicable legislation.
