INFORMATION
If you have to inspect the inside of the domestic hot water
tank, you can access it via the booster heater boss.
The connection of the water piping involves:
▪ Directly to the indoor unit: connecting the water piping to the
space heating inlet, the space heating outlet, and the domestic hot
water outlet.
▪ Via the domestic hot water tank kit: connecting the water piping
to the unit's domestic cold water inlet, and connecting the kit itself
to the drain.
Directly to the indoor unit
INFORMATION
EKVSU260A only: to facilitate maintenance and service,
the space heating and domestic hot water outlets (a and
c), as well as the space heating inlet (b), can be extended
by way of the extension pieces that are delivered with the
domestic hot water tank kit. Make sure to use the sealings
for the extension pieces (delivered as accessory).

To facilitate service and maintenance, 2 shut-off valves are provided.
Mount the valves on the space heating water inlet and space heating
water outlet. Mind their position: the integrated drain valves will only
drain the side of the circuit on which they are located. To be able to
only drain the unit, make sure the drain valves are positioned
between the shut‑off valves and the unit.
