1.1 Cylinder description
The sealed freestanding cylinder (with a volu-
me of 200 or 700 litres) acts as buffer cylinder
for heat pumps.
A buffer cylinder is recommended to ensure
trouble-free heat pump operation. It acts as
a bridge during electricity supply shutdown
periods and as separator between the volume
flow in the heat pump and that in heating
circuits.
Features of the SBP 700 E SOL
The cylinder SBP 700 E SOL is also fitted with
a heat exchanger for boosting the DHW with
solar energy.

1.4 Operating and installation in-
structions
Observe the operating and installation ins-
tructions of the components for each relevant
system.
Keep these operating instructions
in a safe place and pass them on to
any new user, should the equipment change
hands. Let your contractor check their con-
tent in conjunction before commencing any
maintenance or repair work
To prevent damage and contaminati-
on, we recommend that the cylinder
casing is removed for transportation and
installation (see 2.3).
Do not use a barrel clamp!

2.2 Regulations
•Installation and commissioning, as well
as the maintenance of this equipment,
must only be carried out by an authori-
sed qualified contractor in accordance
with these instructions.
•Optimum function and safe operation
can only be assured when using original,
specialised accessories and spare parts
intended for this equipment.
2.3 Place of installation
The installation location should be safe from
frost. If the system is not in use at times when
frost is likely, drain the cylinder and the whole
system connected to it, to prevent damage.
Ensure that the floor at the installation loca-
tion is a load bearing surface, which must be
level and even.
Secure the cylinder feet firmly to the floor to
prevent tipping.
Minimum ceiling height:
1.80 m for SBP 200 E,
2.00 m for SBP 400 E and
2.10 m for SBP 700 E.
2.4 Cylinder casing
assembly / removal
The cylinder casing is fitted in the delivered
condition. It can be removed if necessary.
Removal (E):
1. Removing the plastic lid (20)
2. Removing the plastic plinth cover (21)
3. Removing the plastic casing (19)
Installation in reverse order.
Fit the cylinder casing before instal-
lation work begins on the immersion
heater.
Features of the SBP 700 E and
the SPB 700 E SOL (B)
The two polyurethane foam segments, at-
tached to both sides of the cylinder, can be
removed to ensure safe transportation of the
cylinder through narrow passages and door-
