NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes CO
2
equivalent) is used to determine the maintenance intervals.
Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
2 Fix the label on the inside of the outdoor unit near the gas and
liquid stop valves.
7.8 Connecting the water piping
7.8.1 About connecting the water piping
Before connecting the water piping
Make sure the outdoor and indoor unit are mounted. If applicable,
also make sure the backup heater is mounted.
Typical workflow
Connecting the water piping typically consists of the following
stages:
1 Connecting the water piping to the indoor unit.
2 Connecting the water piping to the backup heater (if applicable).
3 Connecting the recirculation piping.
4 Connecting the drain hose to the drain.
5 Filling the water circuit.
6 Filling the domestic hot water tank.
7 Insulating the water piping.
7.8.2 Precautions when connecting the water
piping
INFORMATION
Also read the precautions and requirements in the
following chapters:
▪ General safety precautions
▪ Preparation
7.8.3 To connect the water piping
NOTICE
Do NOT use excessive force when connecting the piping.
Deformation of the piping can cause malfunctioning of the
unit.
To facilitate service and maintenance, 2 shut-off valves and 1
overpressure bypass valve are provided. Mount the shut-off valves
on the space heating water inlet and space heating water outlet. To
ensure the minimum flow rate (and prevent overpressure), install the
overpressure bypass valve on the space heating water outlet.
1 Install the shut-off valves on the space heating water pipes.
2 Screw the indoor unit nuts on the shut-off valve.
3 Connect the domestic hot water in and out pipes to the indoor
unit.

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
"6.4.3 To
check the water volume and flow rate" on page 26 .
▪ Mind the minimum flow rate when adjusting the
overpressure bypass valve setting. See "6.4.3 To
check the water volume and flow rate" on page 26 and
"9.4.1 To check the minimum flow rate" on page 76 .
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 must be installed on the
domestic cold water inlet connection in accordance with
the applicable legislation.
