Maintenance and repairs:

If no water exits during heating of the water heater or in the event of a permanent leak of the safety valve,

an attempt must be made to loosen the valve by repeated operation of the venting facility or to rinse out

any possible foreign object (e.g. fur particle) on the sealing unit.

If this cannot be achieved, appropriate repairs by a plumber must be initiated. The complete safety valve

must be replaced in the case of any damage to the valve seat or sealing ring.

Implementation: plumber

Time interval: yearly

To test the non-return valve, the shutoff valve is closed and no water must run out of the opened test valve.

The storage tank is operated using the hot water valve of the service fitting (mixer tap). As a result, the sto-

rage tank is constantly under line pressure. To protect the internal boiler from overpressure during heating,

the appearing expansion water is discharged through the safety valve.

In order to avoid damages to the hot water tank from overpressure, it is absolutely necessary to replace

any furred safety valves. The non-return valve prevents the hot water from flowing back into the cold water

supply net in the case of a loss of line pressure, thus protecting the boiler from heating up without water.

Using the shutoff valve, the storage tank can be separated in relation to water and thus also from the cold

water supply network, and emptied through the drain valve, if required.

In order to allow for a trouble-free repair, a removal or exchange of the device, it is necessary to establish

the connection of the tank by means of a detachable connection (Dutch). Tank leaks as a result of an im-

proper connection and resulting damage and consequential damage are excluded from the warranty and

product liability.

NON-PRESSURE CONNECTION

In cases in which fittings are used for non-pressure connection (mixer units), a non-pressure connection

can also be made for pressure-resistant storage tanks.

No safety valve is required in the cold water inflow pipe, although a back-flow valve, shut-off valve and

drainage valve are! This type of connection is beneficial when just one hot water extraction point is requi-

red.

With the control device (mixing unit), the operation of the storage tank takes place via the hot water valve

- this acts as a shutoff device in the storage tank's cold water inlet pipe. This means that hot water abs-

traction from the storage tank will be caused by the hot water valve opening and cold water being forced

from below into the heat storage boiler and in this way the hot water will flow out freely through the hot

water outlet via the mixing unit.

The operating mechanisms for non-pressure connection are constructed in such a way that the hot water

outlet remains open even if the hot water and cold water valves are closed and thus the storage boiler is

connected with the external air. The excess water which occurs during the heating process can flow un-

hindered through the hot water outlet. If necessary, the storage tank can be separated from the cold water

pipe system using the shut-off valve and can be drained via the drainage valve.

Remark: If a pressure-resistant storage tank is connected without pressure, there may be an overrun of

several litres of water after the tapping process has ended which is due to construction reasons (the quan-

tity depends on the volume of the tank). This does not constitute a defect.
