Maintenance; Troubleshooting - ThermoFlow 100 Serie Montage- Und Bedienungsanleitung

4. User instructions
The device must be filled with water before being connected to the electrical supply!
The device should always be connected to a 0.8 MPa pressure relief valve (8)!
If the water in the boiler is heated, the volume will increase. This is referred to as expansion water. The ex-
pansion water will drip away via the pressure relief valve. This is necessary and should not be prevented.

Maintenance

This device does not require any maintenance by the user. Professional maintenance should always be car-
ried out by an expert.
The pressure relief valve discharges expansion water through its funnel. This funnel must be placed in a
continuous downward direction and must always be left open to the atmosphere. A discharge hose is placed
between the funnel and sewer. This construction must always be placed in a frost-free environment.
Check the functioning of the pressure relief valve by turning the large knob on the pressure relief valve once
a year, allowing water to flow out, and closing it immediately. This will prevent the valve of the pressure re-
lief valve from getting stuck. Also check the drain for blockages. If it is blocked, unblock the drain or instruct
a third party to do so.
If you have a complaint or a technical defect, please do not try to repair the device yourself. Contact
Thermoflow customer service at: thermoflow@operatec.de or Tel .: 0355-493 88 50.
Alternatively, please contact your dealer.
Cleaning
The housing of the device can simply be cleaned with a damp cloth. Do not use aggressive cleaners or
cleaners with a scouring effect!
Legislation prevention
Do not use heated water as drinking water. After prolonged shutdown of the device for example due to holi-
days, the device should be fully heated up to the maximum temperature before re-using. It is recommended
to flush the pipes for one minute.

Troubleshooting

Note: in case of problems, always consult the troubleshooter!
If the water in the device is no longer heated, first check whether the plug is properly connected to the wall
socket and whether the fuse of the device group is still working. For all other failures, please consult the
troubleshooter on page. 17.
If the device no longer works because it was connected without being filled with water first, follow the trou-
bleshooter. The device has been overheated and needs to cool down, or possibly repaired.
If the device has been reset several times but still does not work, contact the device customer service or
your dealer.
