Describes what to do to avoid a hazard.
Threats have 3 levels:
Danger
Importance
DANGER
DANGER indicates a hazardous situation, which,
if not avoided, will result in death or serious injury.

2Information on safety
2.1 Intended use of the device
The ABT 50 buffer tank is intended for use in a closed heating or
cooling system in accordance with EN 12828. The ABT 50 buffer
tank is designed for combining various heat/cooling sources with a
heating/cooling system. It enables the combination of one or two so-
urces plus an electric heater.
In the installation with heat pump, buffer guarantees an adequate flu-
id flow through the heat exchanger. With air source heat pumps, it
also ensures that there is sufficient capacity for defrosting the exten-
ral unit when required. Any use other than that indicated in point. 2.1
is forbidden.

3Product description
The ABT 50 buffer tank is a heat or cold storage tank without a coil.
It consists of a rectangular steel casing with welded connections and
external, removable thermal insulation. The tank has a partial baffle
inside, which is responsible for the desired stratified temperature
distribution inside the buffer and at the same time enables the mixing
of supply and return streams. Dedicated wall mounting brackets are
included in the scope of delivery to the buffer tank, which enable
smooth mounting of the buffer storage on a wall. The ABT 50
storage tank is designed for direct connection to the AFRISO KSV
boilers manifolds up to 70 kW and to AFRISO PrimoTherm pump
group with 125 mm installation connections spacing.

3.3 Buffer operation
The ABT 50 buffer tank is a storage tank for heat or cold that, once
accumulated, can be used when the heat/cool source is switched off.
This reduces the on/off frequency of the heat/cool source.
The ABT 50 buffer also acts as a hydraulic low-loss header (in case
of parallel connection) - stabilising the operation of the system as
well as the heat/cool sources.
The buffer increases the water capacity in the system and thus
ensures an adequate minimum fluid flow through the source. This is
a key aspect for the correct operation of the heat pump.
3.4 Scope of delivery

8Installation and commissioning
The installation location of the ABT 50 buffer tank must provide pro-
tection from the atmospheric factors. The buffer tank must not be in-
stalled outdoors. It can be installed in any room protected from tem-
peratures below 0°C. The ABT 50 buffer tank is designed for wall
mounting using the brackets attached to the device and appropriate
mounting anchors depending on the type of wall. The buffer is not
designed to be placed on the floor. To make it easier to install the
brackets, you can use the buffer template included in the package.
Before placing the buffer on the hangers, make sure that the buffer is
already in the thermal insulation. Insulation cannot be put on a buffer
which is already mounted on brackets. For connection of the he-
at/cooling source use the side connections G1¼" F on the left or right
side of the buffer. Unused connections must be plugged with the
plugs which are provided in the delivery. An automatic air vent with
mounting valve must be screwed into the upper G ½" F connection,
and a plug into the lower G ½" F connection. The plug can be repla-
ced by a drain valve (Art.-No 42 407) or a temperature sensor sleeve
(not included in the scope of delivery). Installations can be connected
directly to G1" connections, and when fitting a KSV manifold up to 70
kW or a PrimoTherm pump group to the buffer, use the G1" F half
unions x G1½" union nuts connections which are attached to the
buffer. The buffer tank can be connected to the system from the top,
bottom or side. The internal construction of the tank is indicated by
the embossing on the insulation (Fig. 7).

Depending on the orientation of the buffer, the supply and return
connections from the system may be interchanged (see Fig. 8 for
examples).

manner.

Instruction manual
Buffer tank ABT 50 15
When installing an ABT buffer storage in a closed heating installa-
tion, due to the additional 50 litres of liquid inside the system, it must
be verified that already installed expansion vessel used has suffi-
cient capacity. If the installed expansion vessel is insufficient, the
system must be retrofitted with an additional expansiom vessel or
the existing expansion vessel must be replaced with a vessel with
greater capacity.
WARNING
Risk of burns
Burns can occur from the hot medium during installation and
maintenace work. Ensure that the installation has cooled down
sufficiently before proceeding.
9Selection and instalation of electric element
Depending on the orientation of the ABT 50 buffer tank, the electric
element can be screwed into a dedicated G1½" F connection or into
one of the connections G1¼" F dedicated for a heat source. Depen-
ding on the connection, the maximum installation length of the ele-
ment will be different (Fig. 9). During selection of a connection, the
heater element manufacturer's guidelines must be followed first and
foremost!

WARNING
Mains voltage (230 V AC) can cause serious injury or death.
Do not allow the element cover to come into contact with liquid.
Disconnect the element from the mains before servicing.
Do not make any changes to the device.
Follow the guides which are included in element instruction
manual.

Buffer tank ABT 50 17
10 Maintenance
The integiry of the system connections to the storage tank must be
checked periodically (at least once a year). Also minimum once a
year visual check the condition of the tank and the operation of the
automatic air vent. If a drain valve is screwed into the lower G½" F
connection (not included in the scope of delivery), the medium must
be drained through tis valve from the system at regular intervals to
remove separated impurities.
WARNING
Danger of scalding
Scalding can occur from the hot medium during installation and
maintenance work. Ensure that the installation has cooled down
sufficiently before proceeding.
