a If a multilingual fluorinated greenhouse gases label is
delivered with the unit (see accessories), peel off the
applicable language and stick it on top of a.
b Factory refrigerant charge: see unit name plate
c Additional refrigerant amount charged
d Total refrigerant charge
e Greenhouse gas emissions of the total refrigerant charge
expressed as tonnes CO
f GWP = Global warming potential
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes CO
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.

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.
INFORMATION
The water piping needs to comply with section G3 of the
Building Regulations. To facilitate compliance, domestic
hot water tank kits EKVSU180A and EKVSU260A are
available. The instructions below include the installation of
these tank kits. If they are NOT used, at all times make
sure that the water piping complies with the applicable
legislation.
