Pressure safety.
Water heaters are equipped with a certified safety valve in terms of pressure values standards. Without the need to
remove discharge pipe, a check-valve is used to drain the unit when required.
2-9
Freezing Safety.
When water temperature in your water heater falls below 5°C, heating resistance is automatically activated and heats
the water up to 16°C. In the meantime, lamps with anti ice and heating coil signs illuminate and indicate the
temperature of the water. The anti-freeze safety system activates while the water heater is in stand-by. Install the
water heater in a location safe from risk of freezing. “This safety system is only available in electronically controlled
models.”
2-10
Bacteria Prevention System.
Researches show that when the water is kept under below 60°C for a long time it will become suitable for bacteria
growth. While the device in stand-by, to prevent bacteria from growing the water is heated at least once a week above
65°C and kept at this level for 1 hour. “This safety system is only available in electronically controlled models.”
2-11
Dry Operation Safety.
If your device is operating without water for any reason whatsoever, the system will be activated automatically and
generate E3 error code in the display. In this case disconnect the device using V-automated switch and ensure that the
water heater is filled with water. After ensuring that it is filled with water reconnect to the mains supply, the water
heater will commence its normal operation. “This safety system is only available in electronically controlled models.”
2-12
Low Voltage Protection.
If voltage is dropped to a level harmful for the device due to mains fluctuations, then the low voltage safety system is
activated and E2 error code is displayed. After the voltage is restored to desired level E2 error will disappear and the
water heater will commence its normal operation. “This safety system is only available in electronically controlled
models.”
