8. The installation must be equipped, upstream of the appliance,
with a bipolar cut-out device (fuse, breaker switch) respecting
local regulations (30 mA earth-leakage breaker).
9. If the supply cord is damaged, it must be replaced by a special
cord or assembly available from the manufacturer or the after
sales service.
10. Mandatory installation of a safety device in a frost free location
(or any other new device which limits the tank pressure) to 0.7
or 0.8 MPa (7 or 8 bar) according to the nominal pressure, with
a size matching in the input of the water heater, respecting the
local regulations.
11. Operate regularly the discharge of safety device to prevent
scaling and check that it is not blocked.
12. Hydraulic accessories should not be located between the safety
valve and the cold water inlet. A pressure reducer (not supplied)
is required when the water supply pressure exceeds 0,5 MPa
(5 bar) and will be fitted on the main supply.
13. Connect the safety device to an unpressurised outlet pipe in a
frost free location, with a continuous slope to evacuate water
during heating up or draining the water heater. Each time
heating is operated, a flow occurs through the safety device
valve. Do not obstruct the flow.
14. The pipes used must support 1 MPa (10 bar) and 100 °C.
15. Never power the water heater without water.
16. To drain the device: Switch off the power and the supply of cold
water, open the hot water faucets and manipulate the safety valve.
17. The products described in this manual are subject to changes
at any time to be in accordance with technology and standards.
The devices comply with Electromagnetic Directive 2014/30/
UE, Low Voltage Directive 2014/35/UE, Directive 2011/65/UE
for RoHS and Regulation 2013/814/UE supplementing Directive
2009/125/EC for ecodesign.
18. Processing waste electrical and electronic equipment at
end of life (Applicable in member states of the EU).

pictogram means the product must not be processed
with unsorted household waste. An obligatory system
of disposal and processing of waste
