1 - Description
HSK P Thermal Stores are intended for storing and subsequent distribution of thermal energy of heating water. They are fitted with a stainless-steel tube DHW heat exchanger, permitting installation of electric heating elements and connection of other heat sources. For a better thermal layering, the tank volume is separated by a baffle. For proper operation of a tank, it is necessary to have an optimum hydraulic design of the entire heating system, i.e. position of circulation pumps for both heat sources and heating circuits, valves, check valves etc. When more heat sources shall be combined, it is recommended to use a smart controller for both the heat source and heat sink sides of a heating circuit, i.e. also for charging and discharging a thermal store.
1.1 - Models
Four models of 560, 760, 925 and 1687 l total volume, with stainless-steel tube DHW heat exchanger.
1.2 - Tank protection
The thermal store has no inner surface nish, the outer surface is painted in gray. The DHW heat exchanger is
made of stainless steel.
1.3 - Thermal insulation
Thermal insulation is available as a separate item. For easier handling, the insulation shall not be tted on the tank until it reaches its denite place of installation. The insulation is 100 mm thick, with PUR leather surface, and closes
with a zipper.
1.4 - Packaging
Thermal stores are delivered standing, each screwed to its pallet, packed in bubble wrap.
It is forbidden to transport and/or store the thermal stores in a horizontal position.
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 qualified person according to valid rules and Manufacturer‘s Instructions.
This appliance is designed to accumulate thermal energy and distribute it subsequently. It must be connected to a heating system and heat sources. This appliance is suitable for continuous heating of domestic hot water.
Using the thermal store for other purposes than above described is forbidden and the manufacturer accepts no
responsibility for damage caused by improper or wrong use or filling procedure.
The appliance shall be installed by a qualified person according to valid rules, otherwise the warranty becomes null and void.

4 - Operation
This tank is designed for heating and storing heating water in household or industrial applications, however always in closed pressure circuits with forced circulation. Hot water is heated inside the thermal store from several possible heat sources like various kinds of heating boilers, renewable energy sources or also electric heating elements. A stainless-
-steel tube DHW heat exchanger is heated by heating water inside the thermal store. It connects through 1” threaded
ttings. When hot water is drawn from the outlet point, cold water ows into the immersed heat exchanger and heats
up by the heating water.
The thermal store shall be connected to heat sources through connecting threaded ttings.
Individual connection points are assigned according to the circuits to be connected. There is a wide choice of combi­nations; the following chapter describes just some examples.

6 - Installation and Commissioning
Installation must meet valid rules and may be done only by qualified staff.
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.
6.1 - Connection to heat sources
Place the tank on the floor, as close to your heat source as possible. Connect the heating circuits to inlets and outlets respecting the thermal stratification 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 connection piping
6.2 - Installation of an el. heating element
The G 6/4“ side tappings are designed to accommodate electric heating rods. They can be connected either directly to the mains (thermostat-equipped rods), or to a heating system controller. The installation may be done by qualified staff only.
Warning: Electric heating elements shall be protected by a safety thermostat.
6.3 - Connection to water mains
DHW piping shall be done according to valid rules. Installation of a pressure reducing valve on the immersed tank inlet is recommended. For water mains pressure above 6 bar a pressure reducing valve is necessary. Should the water be too hard, install a water softener before the tank. In case the water contains mechanical impurities, install a strainer.
6.4 - 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.
Quality of DHW shall meet the conditions shown in the Table of limit values for total dissolved solids in hot water on this page.
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 the proper function of all control and adjustment elements.

7 - Installing Insulation on the Tank
Warning
Insulation installation shall be done in two or three persons, depending on its size. The zippered, PVC coated
insulation must not be installed at temperatures below 20 °C. If this cannot be avoided, the insulation shall be pre­warmed 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 fire.
Installing Insulation
1. Fix the tank following installation instructions.
2. Fit the bottom insulation parts.
3. 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.
7
4. Use the holes for tappings as a rest during the insulation installation.
5. At least one person presses the insulation to the tank, pulling both ends together. The other person closes the zipper.
6. Put on the upper insulation and cover
7. Push on the covering plastic rosettes depending on the size of tappings, or put on the flange plug(s) with insulation.
8. Finish the tank installation in compliance with the respective instructions and valid standards and rules.
Warranty on insulation
