1 Safety and
usage instructions
1.1 General safety notes
Carefully read the operating manual before commissioning the units for the first time. It contains
useful tips and notes such as hazard warnings to
prevent personal injury and material damage.
Failure to follow the directions in this manual not
only presents a danger to people, the environment
and the system itself, but will void any claims for
.
liability
Keep this operating manual and the refrigerant
data sheet near to the units.
1.2 Identification of notes
This section provides an overview of all important
safety aspects for proper protection of people and
safe and fault-free operation.The instructions and
safety notes contained within this manual must be
observed in order to prevent accidents, personal
injury and material damage.
Notes attached directly to the units must be
observed in their entirety and be kept in a fully
legible condition.
Safety notes in this manual are indicated by symbols. Safety notes are introduced with signal words
which help to highlight the magnitude of the danger
in question.
DANGER!

1.9 Intended use
The buffer tanks are employed for the storage of
hot water in all types of hot water central heating
systems (solid fuel/oil-fired boilers, heat pumps,
solar plant, gas/electric instantaneous water
heaters) within enclosed spaces and for the
storage of cold water for cooling processes or heat
recovery purposes.
Any other or additional use is a non-intended use.
The manufacturer/supplier assumes no liability for
damages arising from a non-intended use. The
user bears the sole risk in such cases. Intended
use also includes working in accordance with the
operating and installation instructions and complying with the maintenance requirements.
The threshold values specified in the technical
data must not be exceeded.
1.10 Warranty
For warranty claims to be considered, it is essential
that the ordering party or its representative complete and return the "certificate of warranty" to
REMKO GmbH & Co. KG at the time when the
units are purchased and commissioned.
The warranty conditions are detailed in the "General business and delivery conditions". Furthermore, only the parties to a contract can conclude
special agreements beyond these conditions. In
this case, contact your contractual partner in the
first instance.
1.8 Unauthorised modification and changes
The operational safety of the supplied units/
components is guaranteed when used in line with
intended use in accordance with section 1.9 of the
operating instructions. Under no circumstances
should the threshold values specified in the datasheet be exceeded.

3 Unit description
The buffer tanks are employed for the storage of
hot water in all types of warm water central heating
systems (solid fuel/oil-fired boilers, heat pumps,
solar plant, gas/electric instantaneous water
heaters) within enclosed spaces and for the
storage of cold water for cooling processes or heat
recovery purposes.
The storage tank volume can be adapted to your
particular needs by connecting several buf
to form batteries. The buffer tanks may be used
universally, either as parallel buffer tanks (hydraulic
compensators) or series buffers.
The insulation of the buffer tanks is comprised of
50 mm directly applied, CFC-free, fine-pore PU
foam. The external cladding applied ex works is
comprised of a powder-coated steel sheet cladding
in the colour: silver grey, the insulation is water
vapour diffusion proof.
All buffer tanks are manufactured from quality steel
in accordance with DIN EN 10025/10111. An electric auxiliary heater (immersion heater) can be
screwed into each buffer tank via a 6/4" socket.
For retrofitting a fin-tube heat exchanger, a D180
(f=180mm) KPS 300 blank flange cover is fitted to
the storage tank. The buffer tanks are equipped
with 4 ports. A sensor channel enables the KPS
300 variable installation of a heat sensor in the
storage tank.

4 Installation instructions
for qualified personnel
General instructions prior to installation
n Ensure that the area in which the unit is to be
operated is free of frost and easily accessible
for required maintenance, repairs and even for
the possible replacement of the unit (e.g. avoid
narrow passageways and doorways).
n When installing the buf
standard locations, such as in lofts, residential
units with floors that are sensitive to water,
storerooms, etc. take account of the possibility
of leaking water, and ensure that a facility is in
place to collect the water, including appropriate
drainage methods.
n The unit may only be installed and operated on
level surfaces.
n When planning the unit’s installation surface
and selecting the installation location, note the
total weight of the buffer tanks, including the
weight of the water (the nominal capacity), in
order to ensure that the load-bearing capacity
of the support surface is not exceeded.
n Ensure proper clearance from furnace sys-
tems.
n Make sure that the connection block (water
and electric connections and heater installation) of units with enclosures, which are
installed in small, confined spaces or in suspended ceilings are still freely accessible and
that there us no build-up of heat.
n Leave at least 500mm of space free for the
removal of the cleaning/heating flange.

General notes
NOTICE!
Installation should only be performed by authorised specialists.
NOTICE!
Preparation of the hot water must be in compliance with the applicable standards.
n Do not continually top up the water level in the
buffer tank. This will prevent corrosion damage
to the storage tank.
n If corrosive water is a problem, please note
that special models of the storage tanks can be
tested. (address all queries to your contractual
partner).
n The storage tank must be filled in accordance
with the applicable DIN 2035 standard!
Damage that result from non-compliance are
not covered by the guarantee.

7 Care and maintenance
Care
n Clean the units with a damp cloth. (by adding,
for instance, a liquid household cleaner). Do
not use any caustic, abrasive or solvent-based
cleaning products.
Maintenance
n It is recommended that you take out a mainte-
nance contract with an annual service from an
appropriate specialist firm.
This enables you to ensure the operational reliability of the plant at all times!
n Regularly check the function of the safety
valve.

CAUTION!
This can cause the cold water supply and parts
of the storage tank connection fitting to become
hot!
If the storage tank is not heated, no water should
drip from the safety valve. If this does occur
the system pressure is greater than the permitted
value or the safety valve is defective. In both
cases, the system must be tested by qualified personnel.

Temporary shutdown
Temporarily shutdown the plant as follows:
1. Completely switch of
tion.
2. Drain the storage tank in areas where it is at
risk from frost and before the onset of winter
3. In this case also drain the cool and hot water
pipes leading to the heating unit and to the
heat/cold generators as well as water carrying fittings and pipes (also heating cycle =
radiator) to the frost-proof part of the
domestic water system (domestic water connection).
Permanent shutdown
Ensure that units and components are disposed of
in accordance with local regulations, e.g. through
authorised disposal and recycling specialists or at
collection points. REMKO GmbH & Co. KG or your
contractual partner will be pleased to provide a list
of certified firms in your area.
