peratures. This settles inside the appliance and affects both
the performance and service life. If a flanged immersion
heater is installed, the heating elements must be descaled
from time to time. A heating contractor who knows the local
water quality will tell you when the next service is due.
f Check the taps/valves regularly. You can remove limescale
deposits at the tap outlets using commercially available des-
caling agents.

8.2 Transport
!
Material losses
We recommend removing the cylinder casing for trans-
portation to the installation location to prevent it from
becoming dirty or damaged.
SBB 501 WP SOL (GB)
f Both side insulation sections can be removed for transporta-
tion in tight spaces. To do this, remove the cylinder casing.
26�03�20�0003
f Use the fixing straps to refit the thermal insulation sections
after transportation.
D0000095239
1
1
1 Side thermal insulation section
f Ensure that the closures are in the joint between a side
thermal insulation section and the thermal insulation of the
cylinder.
9. Preparing for installation
9.1 Removing / fitting the cylinder casing
Note
Open or remove the cylinder casing before fitting the
high limit safety cut-out and DHW circulation/indirect
coil lines.
Fit the cylinder casing before fitting a flanged immersion
heater.
The plinth trim should be fitted after the tightness check.
9.2 Checking the signal anode
!
Material losses
The appliance must not be operated without a consump-
tion indicator or with a damaged one, otherwise water
will leak out once the anode is depleted.
9.3 Heating installation
The connected heat source must not exceed a maximum flow
temperature of 60 °C or must, alternatively, be equipped with a
high limit safety cut-out. You may also install a motorised valve
that interrupts the cylinder heating by the heat source.
f Flush the indirect coils with water before connecting the
heating water pipes.
9.3.1 Water quality, solar circuit
A glycol/water mixture of up to 60% is permitted for the indirect
coil in the solar circuit if only dezincification-resistant metals,
glycol-resistant gaskets and diaphragm expansion vessels suitable
for glycol are used throughout the installation.
9.3.2 Oxygen diffusion
!
Material losses
Avoid open heating systems and plastic pipes in under-
floor heating systems which are permeable to oxygen.
In underfloor heating systems with plastic pipes that are per-
meable to oxygen and in open vented heating systems, oxygen
diffusion may lead to corrosion on the steel components of the
heating system (e.g. on the indirect coil of the DHW cylinder, on
buffer cylinders, steel heating elements or steel pipes).
!
Material losses
The products of corrosion (e.g. rusty sludge) can settle in
the heating system components and can result in a lower
output or fault shutdowns due to reduced cross-sections.
9.3.3 Solar installation
The circuit must include an air-vent, a check valve and an expan-
sion vessel. The check valve is not required if you are utilising a
Solar compact installation.
f Flush the solar indirect coil with water before connecting the
solar circuit.

9.3.4 SBB401WPSOL (GB) | SBB 501 WP SOL (GB)
without solar installation
f Connect both indirect coils to the “heat pump heating return”
and “solar flow” connections (see chapter “Specification /
Dimensions and connections”).
9.4 Fitting the water connection and the safety
assembly
Note
Carry out all water connection and installation work in
accordance with regulations.
f Flush the line thoroughly.
The max. permissible pressure must not be exceeded (see chapter
“Specification/ Data table”).
f Install a type-tested safety valve in the cold water supply
line. Please note that, depending on the static pressure, you
may also need a pressure reducing valve.
26�02�09�0035
1 2
1 Cold water connection
2 Cold water inlet pipe
f Connect the cold water supply directly to the cylinder or with
the connecting pipe routed between the cylinder feet.
f During fitting, counterhold the fitting with an open-ended
spanner (size 36).
f Check the rigidity of the connecting pipe and secure it further
if required.
See chapter “Specification/ Hydraulic diagram” for general ar-
rangement in schematic form. You can fit the safety assembly in
various positions to suit the space available but it must be placed
in the same order as shown. The safety assembly provided in the
pack is fitted to the cold water supply with the exception of the T&P
valve which is fitted at the top of the DHW cylinder. DHW cylinder
relief valve connections should not be used for other purpose.
No valve should be fitted between the expansion valve and the
DHW cylinder.
f To obtain a balanced water pressure in the cold water and
DHW lines, position the cold water outlet directly on the out-
let side of the pressure reducing valve.
f The expansion valve should not respond under normal oper-
ating conditions as the expansion vessel will accommodate
the water as it expands during the heating process.
f If a secondary return circuit is used then an additional ex-
pansion vessel may be required.
f Run the expansion valve outlet and that of the T&P valve to a
drain via a tundish. The purpose of the tundish is to let water
be seen should these valves respond. The outlet pipe should
not exceed 9 metres in length without forming an air break,
i.e. tundish. The pipe must fall continuously throughout its
length with no additional 90° bends. It must be heat resist-
ant and discharge to a safe visible position away from any
electrical devices. The pipe diameter must not be smaller
than the valve outlet. The two discharge pipes can be joined
together at the point of discharge into a single tundish if
required.
f Size the drain so that water can drain off unimpeded when
the safety valve is fully opened. The blow-off aperture of the
safety valve must remain open towards the atmosphere.
f Fit the blow-off line of the safety assembly with a constant
slope.
f Observe the information in the installation instructions of the
safety assembly.
f Install the expansion vessel.
f Adjust the pre-charge pressure. The pre-charge pressure
should be set to approximately 0.02 MPa below the pressure
reducing valve setting.
9.5 Fitting the thermometer and DHW sensor
26�03�20�0005
1
1 Thermometer
f Insert the thermometer as far as it will go and align it.
f Insert the DHW sensor into the upper “Sensor heat pump
DHW” sensor well (recommended position for energy sav-
ing). For higher levels of DHW convenience, you can alter-
natively insert the DHW sensor into the lower “Sensor heat
pump DHW optional” sensor well (higher energy demand).

D0000072286
f To reset the high limit safety cut-out, press its reset button.
!
Material losses
If the cylinder temperature exceeds 85°C, the high limit
safety cut-out responds and the solar circuit pump is shut
down. This results in a temperature rise in the solar col-
lector. If the collector limit temperature set at the solar
controller is exceeded, a collector emergency stop occurs
(see solar controller operating and installation instruc-
tions).
To ensure safe operation, our solar controllers are preset
at the factory with the following values:
- Set cylinder temperature = 45°C
- Maximum cylinder temperature = 60°C
f If you adjust the settings manually, never set the
maximum cylinder temperature to above 85°C.
