Description
PSWF 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. This thermal store shall be always connected to a sealed
heating circuit with forced circulation. It is fitted with one upper flange
ready to receive a suitably sized tube heat exchanger.
A heat exchanger with 1” connections is installed in the bottom part. Mating
flanges for heat exchangers with either G 1” or G ¾” connections are available
as an option. When no heat exchanger is installed, a blind flange shall be
used (option). These heat exchangers are made of finned copper tubes that
feature larger surface area and better heat transfer. The lower heat exchanger
usually connects to a solar system and the upper one is used for DHW heating
(continuous) which limits significantly the risk of Legionella bacteria
formation. The tanks are also fitted with nine G 6/4“ side sleeves to connect
heat sources, four G ½“ ones for sensor sheaths and one G ½“ connection for a
safety valve. El. heating elements can be installed directly into the 6/4”
connections that are located outside the lower heat exchanger.
In order to reach proper working of the tank, it is necessary to design
optimum hydraulics of the whole system, i.e. position of circulation pumps for
sources and heating circuits, valves, non-return valves etc. When more heat
sources shall be combined, it is recommended to use a smart controller, e.g.
Regulus IR, for both the source and load sides of a heating circuit, i.e. also
for charging and discharging the thermal store.

General Information
This Owners 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 qualified person
according to valid rules and Manufacturer‘s Instructions.
This appliance is designed to accumulate thermal energy of heating water and
distribute it subsequently. It shall be connected to a heating system and heat
sources. The equipment is suitable also for continuous water heating. In such
a case, the customer needs to buy a suitably sized heat exchanger (available
as accessory) and have it installed into the flange.
Using the thermal store for other purposes than above described (e.g. as a DHW
tank) is forbidden and the manufacturer accepts no responsibility for damage
caused by improper or wrong use.

Operation
This thermal store is designed to accumulate thermal energy in domestic or
industrial applications, however always in sealed pressure circuits with
forced circulation. 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 is connected to the energy source using a G 6/4“ connection
fitting. A solar system thermal connects to the outlets of the inbuilt heat
exchanger through G 1” fittings.
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.
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 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.
Connection to a solar system
This tank is suitable for use with a solar system. In such a case the inlet of
heated solar fluid from collectors connects to the G 1” upper connection of
the heat exchanger and the return line from the solar thermal system connects
to its lower connection. Insulate meticulously all the piping between the tank
and the solar thermal system.
El. heating element installation
The tank may be fitted with electric heating elements up to 12kW output
depending on the volume of the thermal store
– see the table of max. output of heating elements in hot water tanks and
thermal stores in the Catalogue. 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.
Commissioning
Ground the tank before commissioning.
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.

mg/l
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 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 center evenly in both directions until the insulation adheres to the tank’s surface completely and no bubbles are left.
- Use the holes for sleeves 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 sleeves, 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 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.
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.
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 Center. Insulation
shall be recycled as plastic and the steel vessel as scrap iron.
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 accumulation tank scope of supply.
