1 - Description
PS 80 ZC Wall-hung thermal store is designed for storing and subsequent distribution of heat/cold. It is suitable as
a buffer tank for inverter heat pumps to ensure sufcient water volume during evaporator defrosting. The tank has
four G 1ʺ M connections to connect sources of heat/cold and a heating/cooling system. It comes with vapour-proof
non-detachable insulation and parts for hanging the tank on a wall.
When needed, an electric heating element without thermostatic head of max. 7.5 kW output can be installed into
the tank, for codes see the Catalogue.
1.1 - Tank protection
The inner surface has no surface nish, no anticorrosion protection. On its lacquered outer surface there is a hard
PU foam insulation covered with alacquered metal sheet.
1.2 - Connection points on the tank
4x G 1“M connection for connecting a heat/cold source and a heating/cooling system
1x G 1/2“ F connection for an air vent valve
1x G 6/4“ F connection for an electric heating element
2x sensor sheaths, diam. 12.6 mm
1.3 - Packaging
The tanks are wrapped in foil and delivered in a box lled with polystyrene.
2 - General Information
This 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. Installation may be done only by qualied staff in compliance
with valid rules, standards and Manufacturer‘s instructions.
This appliance is designed to accumulate and distribute heat/cold. It shall be connected to a heating/cooling system
and sources of heat/cold.
Using the tank for other purposes than stated in this Manual (e.g. as a hot water storage tank) is forbidden
and the manufacturer accepts no responsibility for damage caused by improper or wrong use.

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.
Before installing the tank, check the load-bearing capacity and material of the supporting structure with regard to
the weight of the tank full of water, i.e. 113 kg. Fix the mounting plate to the support structure with two 8x80 mm
hex head screws into 12 mm diameter dowels. All these parts are included in the delivery - see Fig. Then hang the
tank on the mounting plate.
Should the tank be equipped with an electric heating element, it is recommended to install it before
connecting the pipes of the heating system.
After the tank is installed and connected to an existing heating/cooling system, it is recommended to clean the
entire heating/cooling system using a suitable cleaning agent for heating systems.
It is recommended to add protective anti-corrosion uid into the heating system. The respective item codes can be
found in the Catalogue or at www.regulus.eu.
6.1 - Connection to sources of heat/cold
Hang the tank on the wall as close to the heat source as possible (the minimum hanging height of the tank from the
oor when installing a 7.5 kW heater must be at least 650 mm). Connect the source of heat/cold and the heating/
cooling system to inlets and outlets. Install an air vent valve at the highest point of the system. Insulate all the
connection piping.
When using the tank for storing cold or when using it alternately for storing both heat and cold, thoroughly insulate
all parts of the piping, including ttings and equipment connected to the tank (heating element, thermostats etc.)
with vapor barrier insulation to prevent condensation on the surface of these parts.
6.2 - Installation of an electric heating element
The thermal store can be equipped with an electric heating element without thermostatic head (e.g. ETT-A) of
output up to 7.5 kW, max. length 635 mm.
It is recommended to use an encased adjustable thermostat with 1.5m long capillary, code 10772, for switching the
heating element. Place the thermostat sensor into the bottom sheath C2.
Electric heating elements with no thermostatic head shall be protected by a safety thermostat.
It is recommended to use an encased safety thermostat with 1.3 m capillary, code 19548.
Place the thermostat sensor into the sheath C1.
Electric heating elements must be wired by a qualied person only.
6.3 - Commissioning
The tank shall be lled up together with the heating/cooling system, respecting valid standards and rules. In order
to minimize corrosion, special protective additives for heating systems should be used (see the Catalogue). The
quality of heating water, of top-up water and the frequency of topping has a strong inuence on the lifetime of heating
systems. Poor quality of heating water may cause problems like corrosion and incrustation.
Fill the system with the appropriate uid and air-bleed. Check all connections for leaks and verify the system pressure.
Set the heating/cooling 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 before cleaning. 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.
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 Center. 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.
