Common questions about manuals, registration, and support for this brand.
Yes, the device must be completely filled with water and all air purged from the lines by running the hot tap before connecting or turning on the electrical supply. Failure to do so can cause the heating elements to burn out immediately.
Most Thermoflow models require a minimum switch-on water pressure of 0.05 MPa (about 7.3 PSI). Ensure your water supply line meets this requirement to trigger the heating mechanism.
Turn off the main electrical power, open the hot water tap on the connected faucet, turn on the water supply to fill the unit, and let the water run continuously until no more air bubbles emerge.
Verify that the main circuit breaker is turned on, the minimum water pressure/flow rate is being met, and that the cold (blue) and hot (red) water lines are correctly connected. If issues persist, check the internal filter screen for debris or refer to the troubleshooting section of your manual.
For standard zero-pressure installations, a low-pressure tap fitting with three connection hoses must be used, and a flow restrictor should not be installed on the tap spout to prevent pressure buildup inside the device.
