Description
PS N+ Thermal Stores are intended for storing and subsequent distribution of
thermal energy from solid-fuel fired 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 fitted 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
Twelve models of 181, 280, 397, 474, 561, 656, 804, 860, 927, 1040, 1504 and
2005 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
Thermal insulation is available as a separate item. For easier handling, the
insulation shall not be fitted on the tank until it reaches its definite place
of installation. The insulation is made of fleece, 100 mm thick, with a hard
polystyrene
surface. It is closed by a quick lock.

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
fitting. 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 fluid in a solar thermal system. The individual tank
outlets are fitted according to the circuits to be connected.

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. 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 floor, 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 installatio n
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 qualified
person only.
6.4 – Commissioning
Ground the tank before 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 quality 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.
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 fleece 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 fire.
Installing insulation
- Put the bottom insulation under the tank and place the tank following installation instructions.
- 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.
- Use the holes for connections as a rest during the insulation installation.
- At least one person presses the insulation to the tank, pulling both ends together. The other person closes the quick lock from the side.
- Put on the upper insulation and cover.
- Push on the covering plastic rosettes depending on the size of connections, or put on the flange plug(s) with insulation.
- 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 another 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.
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 tank connections for leaks.
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.
Warranty
This product is covered by warranty according to the conditions described in this Manual and according to the Warranty Certificate. A Warranty Certificate is an integral part of the supply
