1 - Description
The wall-hung thermal store PS 80 Z is intended for storing and subsequent distribution of thermal energy. It is
suitable as a buffer tank for inverter heat pumps to ensure a sufcient volume of water for defrosting the evaporator.
The tank has four G 1“ M connections for connecting a heat source and a heating system. It comes with insulation.
If needed, an electric heating element without a thermostatic head can be installed in the tank, 7.5 kW max. output,
for codes kindly consult the Catalogue.
1.1 - Tank protection
Its inner surface is without surface treatment and anti-corrosion protection. Its painted outer surface is tted with
insulation made of hard PU foam that is covered with lacquered sheet metal.
1.2 - Connection points on the tank
4x G 1“ M connections for connecting a heat source and heating system
1x G 1/2“ F connection for air vent valve
1x G 6/4“ F connection for installing an electric heating element
2x sensor sheaths ø 12.6 mm
1.3 - Packaging
Tanks are packed in foil and supplied in a box lled with polystyrene.
2 - General Information
This Operation 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 qualied
person according to valid rules and Manufacturer‘s Instructions.
This device is designed to store heat in heating water and its subsequent distribution. It must be connected to a
heating system and heat sources.
Using the thermal store for other purposes than above described (e.g. as a hot water storage tank) is
forbidden and the manufacturer accepts no responsibility for damage caused by improper or wrong use.

4 - Operation
The thermal store is suitable as a buffer tank for inverter heat pumps to ensure a sufcient volume of water for
defrosting the evaporator, but it can also be used to store thermal energy also with other heat sources, such as
various types of hot water boilers or electric heating elements.

6 - Installation and Commissioning
Installation must meet valid rules and may be done only by qualied 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
Hang the tank on the wall as close as possible to the heat source (minimum height of the tank from the oor must
be at least 650 mm when a 7.5 kW heating element is installed). Connect the heat source and heating system to
the inlets and outlets. Install an air vent valve at the highest point of the system. Insulate all the connecting piping.
6.2 - El. heating element installation
The thermal store can be equipped with an electric heating element without a thermostatic head (e.g. ETT-A), up to
7.5 kW output with a maximum length of 635 mm.
An electric heating elements without thermostatic head shall be protected by a safety thermostat.
The installation may be done by qualied staff only.
6.3 - 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, e.g. MR-501/F. The quality of heating water, top-up
water and the frequency of topping up has a strong inuence on the lifetime of the heating system. Poor quality of
heating water may cause problems like corrosion or incrustation.
Fill the entire system with the heating uid and air-bleed it. Check all connections for leaks and verify the system
pressure. Set the parameters of the used controller in compliance with the documentation and manufacturer’s
recommendations. Check regularly the proper function of all control and adjustment elements.

7 - 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 tank connections for leaks.
8 - Disposal
Packaging 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 Centre. Insulation
shall be recycled as plastic and the steel vessel as scrap iron.
9 - Warranty
This product is covered by warranty according to the conditions described in this Manual and according to the
Warranty Certicate. A Warranty Certicate is an integral part of the supply.
