1 - Description
PS K+ Thermal Stores of reduced height are intended for storing and subsequent distribution of thermal energy from
solid-fuel red boilers, heat pumps, solar collectors, electric boilers etc. These tanks do not enable installation of heat
exchangers, only direct installation of an electric heating element. 230V or 3x230V/400V heating elements (2-12 kW
output) can be installed directly into the 6/4” connections. Tanks are tted with nine connections for heat sources and
a heating system, four connections for installing sensor sheaths and one connection for a safety valve. A 100mm thick
insulation for these tanks can be purchased as a separate item.
1.1 - Models
Six models of 403, 477, 560, 737, 861 and 1085 l capacity.
1.2 - Tank protection
The inner surface has no nish, no anticorrosion protection, the outer surface is lacquered in gray.
1.3 - Thermal Insulation
Thermal insulation is available as a separate item. For easier handling, the insulation shall not be tted on the tank
untilit reaches its denite place of installation. The insulation is made of eece, 100 mm thick, with a hard polystyrene
surface. It is closed by a quick lock.
1.4 - Connection points on the tank
8× side connections in a circular section of 90°, G 6/4“ F thread
1× top connection, G 6/4“ F thread“
4× side connections for sensor sheaths, G 1/2“ F thread
1× connection for installation of a 3bar safety valve, G 1/2“ F thread
1.5 - Packaging
Thermal stores are delivered standing, each screwed to its separate pallet, packed in bubble wrap.
2 - General Information
This Manual is an integral and important part of the product and must be handed over to the User. Read carefully
the instructions in this Manual as they contain important information concerning safety, installation, operation and
maintenance. Keep this Manual for later reference. The appliance shall be installed by a qualied person according to
valid rules and Manufacturer‘s Instructions, otherwise the Warranty is null and void.
This appliance is designed to accumulate thermal energy of heating water and distribute it subsequently. It must be
connected to a heating system and heat sources.
Using the thermal store for other purposes than above described is forbidden and the manufacturer accepts
no responsibility for damage caused by improper or wrong use. The thermal store must not be used as a hot

4 - Operation
In a thermal store, heating water can be heated up by various types of hot-water boilers, renewable energy sources
(heat pumps, solar collectors), or possibly also by electric heating elements.
The thermal store is connected to the energy source using a G 6/4“ connection tting. Should the tank be connected to
a solar thermal system, a heat exchanger shall be used for the connection because heating water is not used as the heat
transfer uid in a solar thermal system. The individual tank outlets are tted according to the circuits to be connected.

6 - Installation and Commissioning
Installation shall meet valid rules and may be done by qualied staff only.
Defects caused by improper installation, use or handling are not covered by warranty.
After the tank is installed and connected to an existing heating system, it is recommended to clean the entire
heatingsystem using a suitable cleaning agent, e.g. BP 400.
Anti-corrosion protective liquid should be also used, e.g. BP 100 Plus.
6.1 - Connection to heat sources
Place the tank on the oor, as close to your heat source as possible. Fit the insulation, cf. Installing Insulation on the
Tank. Connect the heating system according to the recommended connection layout - see Chap. 5.Install a drain valve
at the lowest point of the tank. Install an air vent valve at the highest point of the system. Insulate all the connecting
piping.
6.2 - Connection to a solar thermal system
This thermal store is primarily not designed to be connected to a solar thermal system. However, when needed, such
a connection can be done by means of a heat exchanger between the solar thermal system and the thermal store. In
such an event, all the connecting piping between the tank and this heat exchanger shall be thoroughly insulated.
6.3 - El. heating element installation
These thermal stores can be equipped with electric heating elements of output up to 12 kW depending on the volume of
the thermal store - see the table of max. output of heating elements in hot water tanks and thermal stores. They can be
connected either directly (elements with integrated thermostat) or via the controller of the entire heating system.
All electric heating elements shall be protected by a safety thermostat.
The electric heating element shall be wired by a professionally qualied person only.
6.4 - Commissioning
This tank is not designed for DHW heating.
The tank shall be lled up together with the heating system, respecting valid standards and rules. In order to minimize
corrosion, special additives for heating systems should be used. The quality of heating water depends on the quality of
lling water at commissioning, on the top-up water quality and on the frequency of topping up. This has a strong inuen-
ce on the lifetime of heating systems. Poor quality of heating water may cause problems like corrosion or incrustation,
esp. on heat transfer surfaces.
Fill the heating circuits with the appropriate uids and air-bleed the entire system. Check all connections for leaks
and verify the system pressure. Set the heating controller in compliance with the documentation and manufacturer’s
recommendations.
Check regularly proper function of all control and adjustment elements.
7 - Installing Insulation on the Tank
Product description
Fleece insulation with a hard polystyrene surface, closed by a quick lock.
Warning
Insulation installation shall be done in two or three persons, depending on its size. The PU leather surface coated eece
insulation must not be installed at temperatures below 20 °C. If this cannot be avoided, the insulation shall be pre-
-warmed in another room to at least 20 °C. It is impossible to install insulation of lower temperature, there is a risk of
damage.
Do not use any tools for installation.
Keep away from open re.
Installing insulation
1. Put the bottom insulation under the tank and place the tank following installation instructions.
2. Wrap the insulation around the tank carefully. Check that the insulation adheres to its body perfectly. This can be
reached by rubbing and patting the insulation by hand from its centre evenly in both directions until the insulation
adheres to the tank’s surface completely and no bubbles are left.
3. Use the holes for connections as a rest during the insulation installation.
4. At least one person presses the insulation to the tank, pulling both ends together. The other person closes the quick
lock from the side.
5. Put on the upper insulation and cover.
6. Push on the covering plastic rosettes depending on the size of connections, or put on the ange plug(s) with insulation.
7. Finish the tank installation in compliance with the respective instructions and valid standards and rules.

Warranty on insulation
The insulation is covered by a 24-month warranty. This period starts the next day after the insulation is sold.
□ Warranty shall become null and void if:
○ the procedure described in the Installation Manual was not respected,
○ the product was used for other purposes than intended.
□ Warranty does not cover:
○ usual wear and tear,
○ damage caused by re, water, electricity or another natural disaster,
○ defects caused by failure to use the product in compliance with its intended purpose, by improper use and
insufcient maintenance,
○ defects caused by mechanical damage to the product,
○ defects caused by tampering or incompetent repair.

8 - Maintenance
If the tank is tted with a heating element, disconnect it from the mains rst. Clean the exterior of the tank with a soft
cloth and a mild detergent. Never use abrasive cleaners or solvents.
Check all tank connections for leaks.
9 - Disposal
Packaging shall be disposed of in compliance with the valid rules. When the product reaches the end of its life, it shall
not be disposed of as household waste. It shall be dropped off at a Local Waste Recycling Centre. Insulation shall be
recycled as plastic and the steel vessel as scrap iron.
