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.
1.2 Special accessories

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-

ways. To do this, undo the retaining straps (17)
at the buckles (18). In the installed condition,
the buckles should be near a joint (segment/
cylinder thermal insulation).
Information about using additional connectors
for the sensor protection sleeve of the SBP 700
cylinder (B)
Should it be necessary to install further sen-
sor protection sleeves in the cylinder, two
additional connectors are available at the top
and bottom, under the foam insulation (11).
To do this, drill holes at the marked places of
the plastic casing with, for example, a 70 mm
hole saw. Remove the thermal insulation from
around the connectors so that the sensor pro-
tection sleeves can be fitted.
2.5 Immersion heater installation
(C, D)
To boost the heat input, one electric immersi-
on heater can be installed into the
SBP 200 E and SBP 400 E (either from the right
or from the left); two immersion heaters can
be installed into model SBP 700 E. To do this,
remove the connector cap (10) and unscrew
the vent plug. Removing the vent plug requires
a socket wrench (SW 32).

Installation
The WPKI 5 set is delivered in pre-assembled
individual parts. All pre-assembled parts are
factory sealed.
It is recommended that the components in the
WPKl 5 set and the selected circulation pump
are connected to the cylinder and tightened by
hand before installation. Once all components
have been connected to the cylinder, tighten
all fittings. Connect the expansion vessel and
the fill/drain valve to the pre-determined con-
nector (32) and (26).
Connect heat pump flow and return to the
heat pump at positions (28) and (29).
Ensure that it is impossible to shut- off the safety valve on the heat
source..
When there is a risk of frost in the alternative
system, install a drain valve on-site to drain
the external air/water heat pump (WPL con-
nection hoses).
All shut-off devices are ball shut-off valves,
which provide a good seal. A spanner
(SW 19) is recommended to open and close
the shut-off valves (24).
Circulation pump (cylinder primary pump)
The pump output curve (F) and the pressure
loss of the WPKl 5 (G) can provide helpful
information on which circulation pump set to
select. Subject to the heat pump type and the
following connection mode (H), at standard
length, we recommend a circulation pump set
from the following table.

2.7 Commissioning
(to be implemented only by a quali-
fied contractor)
 Fill and vent the freestanding cylinder.
 Follow user and installation instruc-
tions and check the functions of spe-
cial accessories (immersion heater).
 Check the safety valve function.
2.8 Maintenance
•When working on permanently fitted
electrical components, disconnect every
part of the equipment from the mains.
•Regularly vent the safety valve until
water flows from it. Shut off the safety
valve after the inspection.
