1 - Description
PS K+ Thermal Stores are intended for storing and subsequent distribution of thermal energy from solid-fuel fired
boilers, heat pumps, solar collectors, electric boilers etc. No heating coils can be installed into these tanks, just an el.
heating rod. Heating elements of 2-12 kW output can be installed directly into the 6/4” sleeves that are power supplied
either with 230V or 3x230V/400V. Tanks are fitted with nine side sleeves to connect heat sources, four for sensor
sheaths and one for a safety valve. As an option, 100mm thick insulation for these tanks is sold separately.
1.1 - Models
Six models of 403, 477, 560, 737, 861 and 1085 l capacity.
1.2 - Tank protection
The inner surface has no finish, no anticorrosion protection, the outer surface is lacquered in gray.
1.3 - Thermal insulation
Tank insulation is available as a separate item, installed on the tank on the spot for easier handling. The insulation is
made of 100 mm thick fleece and fitted with a zippered outer layer in PU leather.
1.4 - Connection points on the tank
8 side sleeves in a 90° sector, G 6/4” F thread
1 top sleeve, G 6/4” F thread
4 side sleeves for sensor sheaths, G ½” F thread
1 side sleeve for a 3 bar safety valve (included), G ½” F thread
1.5 - Packing
Tanks are delivered standing, each screwed to its pallet, packed in bubble wrap.
2 - General Information
This Owners Manual is an integral and important part of the product and must be handed over to the User. Read care-
fully 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 qualified person according to
valid rules and Manufacturer‘s Instructions, otherwise the warranty is null and void.
This appliance is designed to accumulate heating water and distribute it subsequently. It shall be connected to a heat-
ing system and heat sources.
Using the thermal store tank 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 shall not be used
as a DHW tank!

4 - Operation
In the thermal store, heating water is heated up from several heat sources like various types of hot-water boilers,
renewable energy sources (heat pumps, solar collectors), or electric heating elements.
The thermal store shall be connected to a heat source through G 6/4” threaded fittings. Should the tank be connected
to a solar system, this must be done via a heat exchanger because solar systems are not filled with heating water.
Individual connection points are assigned according to the circuits to be connected. There is a wide choice of combi-
nations, just some examples are described in the following chapter.

6 - Installation and Commissioning
Installation shall meet valid rules and may be done by qualified 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 heating
system using a suitable cleaning agent, e.g. MR-501/R.
Anti-corrosion protective liquid should be also used, e.g. MR-501/F or F1.
6.1 - Connection to heat sources
Place the tank on the floor, as close to your heat source as possible. Mount the insulation, cf. Installing Insulation on
the Tank. Connect the heating circuits to inlets and outlets respecting the thermal stratification in the tank. 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 system
The tank can is not primarily intended for use with a solar system but if needed, this can be done via a heat exchang-
er between the solar system and the tank. In such a case, insulate well all the piping between the tank and the solar
system.
6.3 - El. heating element installation
The tank may be fitted with electric heating elements up to 12kW output. They can be power-supplied either directly
(elements with built-in thermostat) or via a controller for the entire heating system.
All electric heating elements shall be protected by a safety thermostat.
Electric heating elements shall be installed by an authorized person only.
6.4 - Commissioning
This tank is not designed for DHW heating.
The tank shall be filled 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
filling water at commissioning, on the top-up water and on the frequency of topping up. This has a strong influence 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 fluids 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
Instructions
Product description
Fleece thermal insulation with PU leather surface.
Warning
Insulation installation shall be done in two or three persons, depending on its size. The 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, esp. to the zipper.
Do not use any tools for installation.
Keep away from open fire.
Installing Insulation
1. Fix 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 center evenly in both directions until the insulation
adheres to the tank’s surface completely and no bubbles are left.
3. Use the holes for sleeves 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 zip-
per.
5. Put on the upper insulation and cover.
6. Push on the covering plastic rosettes depending on the size of sleeves, or put on the flange 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 fire, water, electricity or a natural disaster,
○ defects caused by failure to use the product in compliance with its intended purpose, by improper use and
insufficient maintenance,
○ defects caused by mechanical damage to the product,
○ defects caused by tampering or incompetent repair.

8 - Maintenance
If the tank is fitted with a heating element, disconnect it from the mains first. Clean the exterior of the tank with a soft
cloth and a mild detergent. Never use abrasive cleaners or solvents.
Check all connections for leaks.
9 - Disposal
Packing 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 Center. Insulation shall be
recycled as plastic and the steel vessel as scrap iron.
10 - Warranty
This product is covered by warranty under the conditions listed in this Manual and in compliance with the Warranty
Certificate. A Warranty Certificate is an integral part of this thermal store tank scope of supply.
