1 - Description
PSWF N+ Accumulation Tanks are intended for accumulation and subsequent distribution of thermal energy from sol-
id-fuel red boilers, heat pumps, solar collectors, electric boilers etc. This accumulation tank shall be always connected to a sealed heating circuit. It is tted with one upper ange ready to receive a suitably sized tube heat exchanger.
A heat exchanger with 1” connections is installed in the bottom part. Mating anges for heat exchangers with either G
1” or G ¾” connections are available as an option. When no heat exchanger is installed, a blind ange shall be used
(option). These heat exchangers are made of nned 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 signicantly the risk of Legionella bacteria formation. The tanks are also tted with nine G
6/4“ side sleeves to connect heat sources, four G ½“ ones for sensor sheaths and one G ½“ sleeve for a safety valve.
El. heating elements can be installed directly into the 6/4” sleeves.
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 an intelligent controller, e.g. Regulus IR, for both the source and load
sides of a heating circuit, i.e. also for charging and discharging the accumulation tank.
1.1 - Models
Six models of 280, 472, 807, 930, 1498 and 1997 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
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 eece and tted with a zippered outer layer in PU leather.
1.4 - Connection points on the tank
1 ange with 210 mm inner diam.
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
2 side sleeves for a heat exchanger, G 1” F thread
1.5 - Packing
Tanks are delivered standing, each screwed to its pallet, packed in bubble wrap.
Included in the package are gaskets, bolts for the ange and a 3 bar safety valve with G ½” M/F thread.
2 - 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 qualied person according to
valid rules and Manufacturer‘s Instructions.
This appliance is designed to accumulate 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 ange.
Using the accumulation tank 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.

4 - Operation
This accumulation tank is designed to accumulate heat and heat water for space heating in domestic or industrial
applications, however always in sealed pressure circuits with forced circulation. In the accumulation tank, 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 accumulation tank shall be connected to a heat source through G 6/4” threaded ttings. A solar system connects
to the outlets of the inbuilt heat exchanger through G 1” threaded ttings.
Individual connection points are assigned according to the circuits to be connected. There is a wide choice of combinations, just some examples are described in the following chapter.

6 - Installation and Commissioning
Installation shall meet valid rules and may be done by qualied 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 oor, 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 stratication 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
This tank is suitable for use with a solar system. In such a case the inlet of heated solar uid from collectors connects to
the G 1” upper sleeve of the heat exchanger and the return line from the solar system connects to its lower sleeve. Insulate meticulously all the piping between the tank and the solar system.
6.3 - El. heating element installation
The tank may be tted 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
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 and on the frequency of topping up. This has a strong inuence 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
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 re.
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 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 a natural disaster,
○ defects caused by failure to use the product in compliance with its intended purpose, by improper use and
insufcient maintenance,
○ defects caused by mechanical damage to the product,
○ defects caused by tampering or incompetent repair.
