REMKO KPS 300
Description
The storage 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 energy systems, gas/electric
instantaneous water heaters) within
enclosed spaces and for the storage of
cold water for cooling processes or heat
recovery purposes.
The tank volume can be adapted to
your particular needs by connecting
several storage tanks to form batteries.
The storage tanks may be used
universally, either as parallel storage
(hydraulic switch) or series storage.
The insulation of the storage tank
is comprised of 50 mm directly
applied, CFC-free, fine-pore PU foam.
The external cladding applied at the
factory is comprised of a powder-coated
steel sheet cladding in the colour:
silvery-grey; the insulation of the KPS
300 is water vapour diffusion-tight.
All storage tanks are manufactured from
quality steel in accordance with DIN EN
10025/10111. An electric booster heater
(immersion heater) can be fitted into
each storage tank in a 6/4" socket.
For retrofitting a fin-tube heat
exchanger, a D180 (f=180mm) blank
flange cover is included.
The storage tanks have 4 connection
ports 5/4"AG. A sensor channel enables
variable positioning of a temperature
sensor.
Decommissioning
Temporary shutdown
1. Disconnect the electrical connection
at all poles.
2. Drain the tank in areas where it is at
risk from frost and before the
onset of winter.
3. Then also drain all cold water pipes
or hot water carrying lines leading
to the heating elements and
to the heater/cooler as well as
all water-carrying fittings and lines
(including heating circuit = register)
back as far as the frost-proof
section of the domestic water system
(domestic water connection).
Permanent decommissioning
Ensure that equipment 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 near you.
! ATTENTION
When emptying the tank, hot
water may escape!
! ATTENTION
When placing the tank back into
service, ensure that it is filled with
water and that water which is free
of bubbles is escaping from the
valves!

Care and maintenance
Care
■
Only clean the units with a
damp cloth
(adding, for instance, a liquid
household cleaner.
Do not use any harsh, scouring
or solvent-based cleaners.)
Maintenance
■
We recommend concluding a
maintenance contract with a
specialist firm, which includes annual
maintenance services.
NOTE
This ensures the operational
reliability of your equipment!
■
Regularly check the function of
the safety valve.
The expansion water amount at
maximum heat (approx. 80°C) represents
approx. 3.5% of the tank capacity.
When the safety valve test knob is
lifted or turned to the “Test” position,
the water must flow unhindered out of
the safety valve body into the drainage
funnel.
! ATTENTION
This can cause the cold water
supply and parts of the storage tank
connection fitting to become hot!
If the tank is not heated or when warm
water is removed, no water should be
dripping from the safety valve. If this
does occur, either the pressure in the
water pipe is greater than the permitted
value, or the safety valve is defective. If
the pressure in the water pipe is higher
than permitted, a pressure relief valve
must be used.
Installation instructions
for qualified personnel
General instructions prior to installation
■
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 overly narrow
thoroughfares and doorways).
■
When installing the storage tank in
unusual 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 catch the water,
including appropriate drainage
methods.
■
The unit may only be positioned and
operated on level surfaces.

storage tank, including the weight
of the water (the nominal capacity),
in order to ensure that the statics
of the load-bearing surface are not
exceeded.
! ATTENTION
The storage tank is not suitable for
preparing drinking water!
Central heating connection
Before being placed into service, the
heat distribution must be rinsed out in
order to remove any soiling (e.g. scale)
from the heating circuit.
Installation
■
■
■
Check the contents of the packaging
for completeness and check the
unit for visible transport damage.
Immediately notify your contractual
partner of any deficiencies.
The unit must be assembled on site.
For all connection ports, ensure that
the thread is fully engaged.
■
Ensure proper clearance from firing
systems.
■
Make sure that units with enclosures,
which are installed in small, tight
spaces or in suspended ceilings
have the connection block (water
and electric connections and heater
installation) still freely accessible and
that there us no buildup of heat.
■
Leave at least 500mm of space free
for the removal of the cleaning/
heating flange.
