1 - Description
PS E+ Accumulation Tanks are intended for accumulation and subsequent distribution of thermal energy from solid-fu-
el red boilers, heat pumps, solar collectors, electric boilers etc. No heating coils can be installed into these tanks,
just an el. heating rod. Heating rods of 2-12 kW output can be installed directly into the 6/4” sleeves that are power
supplied either with 230V or 3x230V/400V. Tanks are tted with four side sleeves, one top sleeve and two sleeves for
sensor sheaths. 100mm thick insulation for these tanks is sold separately.
1.1 - Models
Five models of 473 l, 756 l, 927 l, 1038 l and 1260 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 PU leather jacket.
1.4 - Connection points on the tank
4 side sleeves, G 6/4“ F
1 top sleeve, G 6/4“ F
2 side sleeves for sensor sheaths, G 1/2“ F
1.5 - Packing
Tanks are delivered standing, each screwed to its pallet, packed in bubble wrap.

4 - Operation
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 rods.
The accumulation tank shall be connected to a heat source through G 6/4” threaded ttings. Should the tank be co-
nnected to a solar system, this must be done via a heat exchanger because solar systems are not lled with heating
water. 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.
5 - Typical Installation Examples
Example I.
Solid fuel boiler and el. heating rod.
Example II.
Gas red boiler and hydronic replace.

6 - Installation and Commissioning
Defects caused by improper installation, use or handling are not covered by warranty.
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 or some other supplied by Regulus.
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
The tank can is not primarily intended for use with a solar system but if needed, this can be done via a heat exchan-
ger between the solar system and the tank. In such a case, insulate well all the piping between the tank and the solar
system.
6.3 - Heating rod installation
The tank may be tted with electric heating rods up to 9 kW (12 kW) output. They can be power-supplied either direct-
ly (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 rods shall be installed by an authorized person only.
6.4 - Commissioning
This tank is not designed for DHW heating.
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 reco-
mmendations. Check regularly proper function of all control and adjusting 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 zippered eece 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.
How to install soft foam insulation with a PVC layer
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
zipper.
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
insufcient maintenance,
○ defects caused by mechanical damage to the product,
○ defects caused by tampering or incompetent repair.

8 - Maintenance
If the tank is tted with a heating element, disconnect it from the mains rst. 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.
9 - Disposal
Packing 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.
10 - Warranty
This product is covered by warranty under the conditions listed in this Manual and in compliance with the Warranty
Certicate. A Warranty Certicate is an integral part of this accumulation tank scope of supply.
