Installation and maintenance work shall 

only

 be performed by a qualified 

person, familiar with local code and regulation, and experienced with this 

type of appliance.

All field wiring must be installed in accordance with the national wiring 

regulation.

This appliance is not intended for use by persons (including children) with 

reduced physical, sensory or mental capabilities, or lack of experience and

knowledge, unless they have been given supervision or instruction 

concerning use of the appliance by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the 

appliances.

Do not

 attempt to repair the appliance yourself.

The electrical water heater must be installed with a mono-directional 

Pressure Relief Valve at the inlet pipe. The pressure relief device is to be 

operated regularly to remove lime deposit and to verify that there is no 

blockage.

The water may drip from the Discharge Pipe of the pressure relief device 

and that this pipe must be left open to surrounding air. A Discharge Pipe 

connected to the pressure-relief device is to be installed in a downward 

direction and in a frost-free environment.  

The electrical water heater must be prefitted with isolation barriers at both 

inlet and outlet connections. 

The heater must be permanently connected to the electricity supply through 

a double-pole-linked switch with a contact separation of at least 3mm in

all poles incorporated in the circuit.

If the supply cord is damaged, it must be replaced by the manufacturer,  

service agent or a similarly qualified personnel in order to avoid hazards.

In order to avoid hazards due to inadvertent resetting of the thermal cut-out,

this appliance can not be supplied through an external switching device, 

such as a timer, or connected to a circuit that is regularly switched on and 

off by the utility.
