Installation guidelines
Keep in mind the following guidelines when installing the domestic
hot water tank:
The installation location is frost-free.
Make sure to make the piping in size 1" or more (and reduce to
3/4" at the inlet of the tank) as to have sufficient water volume in
the piping between unit and domestic hot water tank.
Locate the domestic hot water tank in a suitable position to
facilitate easy maintenance; remember access is required to the
electrical box. Refer to the grey zones in the outlook diagram.
The domestic hot water tank model
EKHWSU150B3V3 can be floor or wall
mounted. In case of wall mounting, wall
mounting kit EKWBSWW150 is required
(separate ordering).
If installing an EKHWSU* domestic hot water tank, installing the
option kit EKUHWB is obligatory. Refer to the UK Building
Regulation G3.
If installing the kit EKSOLHWAV1, installing the option kit
EKUHW2WB is obligatory.
Take care that in the event of a leak, water cannot cause any
damage to the installation space and surroundings.
Installing the domestic hot water tank
1 Check if all domestic hot water tank accessories (see
"Accessories" on page 1) are enclosed.
2 When floor mounting, place the domestic hot water tank on a
level surface. When wall mounting (only for EKHWSU150B3V3
model), make sure the wall is sturdy. In both cases, make sure
the tank is mounted level.
3 Apply thermal paste to the thermistor and insert the thermistor
as deep as possible in the thermistor socket. Fix using the nut
provided.
Connecting the water circuits
Refer to "Typical application examples" described in the installation
manual delivered with the unit for details on connecting the water
circuits and the motorised 3-way valve.
Connecting the 3-way valve
