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 connect-
ed 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 signicantly 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 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 qualied person according to

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 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 qualied 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 stratication 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. Insu-
late 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 inuence 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 recom-
mendations. Check regularly proper function of all control and adjustment elements.
