▶Remove packaging.
▶ Remove casing lid and, if necessary, insulation.
▶ Remove the foil jacket and store it temporarily.
▶ Unscrew the cylinder from the pallet. Retain the screws for
alignment.
▶ Position the cylinder and align with the fixing screws.
▶ Fit the top insulation and casing lid.
▶ Remove the bung from the connector.
4.4 Hydraulic connection
Before installing the pipework:
▶ Install the thermal insulation/foil jacket.
Observe the technical guide when establishing the hydraulic connection.
DANGER
Risk of fire from soldering and welding!
▶ As far as possible, carry out any soldering and welding work before
installing the thermal insulation.
▶ Take appropriate safety measures when soldering and welding as the
thermal insulation is combustible (e.g. cover thermal insulation).
▶ Check the integrity of the thermal insulation after completing work.
NOTICE
Water damage from leaking connections.
▶ Fit all connecting pipework free from stress.
To avoid damage to the cylinder:
▶ Use installation material on the heat source side that is temperature-
resistant up to 90 °C.
▶ Only use the cylinder in sealed systems.
▶ Never use open, vented expansion vessels.
We recommend using screw fittings with shut-off valves to connect
pipework to the cylinder.
▶ Install a drain valve on site at the lowest point of the bottom
connection.
▶ Vent the heating water side of the cylinder during filling via the air
vent valve at the top of the cylinder.
4.5 Immersion heater (accessory)
▶ Install the immersion heater in accordance with the separate
installation instructions.
▶ Once the cylinder is fully installed, inspect the protective conductor.
This should also include the metal connection fittings.
5 Commissioning
NOTICE
System damage due to positive pressure!
▶ Observe the maximum operating pressure (tab. 20, page 20).
Commissioning must be performed by an approved contractor.
▶ Check the tightness of all connections ( Fig. 15, page 39).
▶ Commission all assemblies and accessories as specified in the
manufacturer's technical documentation.
5.1 Instructions for the user
▶ Explain the operation and handling of the heating system and
cylinder, making a particular point of safety-relevant features.
▶ Point out the need for regular maintenance, as the function and
service life depend on this. The cylinder itself is maintenance-free.
▶ When there is a risk of frost and decommissioning is necessary,
drain the cylinder completely, including the lower section of the
container.
▶ Explain the function and how to check the pressure relief valve.
▶ Hand all enclosed documents over to the user.
6 Decommissioning
DANGER
Risk of scalding from hot water!
Hot water can cause serious burns.
▶ Allow the cylinder time to cool down following decommissioning.
NOTICE
Cylinder damage from frost!
If there is a risk of frost when you are away from home, we recommend
the following:
▶ Leave the cylinder in operation.
or
▶ Take the cylinder out of operation and drain it.
▶ If an immersion heater has been installed (accessory), isolate the
cylinder from the power supply.
▶ Switch off the temperature controller at the control unit.
▶ Drain the cylinder completely.
▶ Decommission all assemblies and accessories of the heating system
as specified in the manufacturer's technical documentation.
▶ Open the system drain valve.
▶ For ventilation, open the air vent valve. The air vent valve is located at
the top of the cylinder.
▶ Close the shut-off valve.
To prevent corrosion:
▶ Leave the connector pipes open, so that the interior can dry out well.
