Typical workflow

Connecting the water piping typically consists of the following stages:

Connecting the water piping of the outdoor unit.

Connecting the water piping of the external backup heater kit and/or the
domestic hot water tank (if applicable).

Protecting the water circuit against freezing (addition of glycol or installation of
freeze protection valves).

Filling the water circuit.

Filling the domestic hot water tank (if applicable).

Insulating the water piping.

INFORMATION

For instructions regarding the domestic hot water tank, see the installation manual
of the tank.

For instructions regarding the external backup heater kit, see:

▪

The installation manual of the backup heater kit.

▪

"To connect the backup heater kit"

[

100] (this topic partially supersedes the

installation manual of the backup heater)

8.2.2 Precautions when connecting the water piping

INFORMATION

Also read the precautions and requirements in the following chapters:

▪

"2 General safety precautions"

[

▪

"8.1 Preparing water piping"

[

71]

8.2.3 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

When connecting the field piping, hold the nut on the inside of the unit in place using
a spanner to provide extra leverage.

Connect the shut-off valve (with integrated filter) to the outdoor unit water
inlet, using thread sealant.
