Troubleshooting

• Incorrect handling of thermostat, safety valve or other valves may lead to tank rupture. When servicing the unit

follow instructions carefully:

•  Always turn off main power supply when water supply is being shut off.
•  Test the free operation of the safety valve regularly by opening the valve ensuring the water flows freely.
•  Electrical connection and all servicing of the electrical components should only be carried out by an authorized

electrician.

• Fitting and all servicing of plumbing fixtures should only be carried out by an authorized installer.
• When replacing the thermostat, safety valve or any other valve or part supplied with this unit, use only approved

parts of the same specification.
