Description
PS2F 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. Thermal stores are fitted with two
flanges; each can be fitted with a suitably sized tube heat exchanger
depending on the selected application and required output. Mating flanges for
heat exchangers with either G 1” or G ¾” connections are supplied with PS2F
N+ thermal stores. When no heat exchanger is installed, a blind flange shall
be used.
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 thermal 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“ connections to connect heat sources
and heating system, 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.

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. 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.
6.2 – Connection to a solar thermal system
This tank is suitable for use with a solar thermal system. In such a case a
suitably sized heat exchanger shall be installed into the lower flange.
Insulate meticulously all the piping between the tank and the solar thermal
system.
6.3 – 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.
6.4 – 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.

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.
