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
f Both side insulation sections can be removed for transporta- f
tion in tight spaces. To do this, remove the cylinder casing.
f Use the fixing straps to refit the thermal insulation sections f
after transportation.

1 Side thermal insulation section
f Ensure that the closures are in the joint between a side f
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 DHW
circulation and 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

f Flush the indirect coils with water before connecting the f
heating water pipes.
SBB 401 WP SOL | SBB 501 WP SOL without solar installation
f You may connect both indirect coils to the "heat pump heat- f
ing return" and "solar flow" (see chapter "Specification /
Dimensions and connections").
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.
