Important instructions for the user
Safety instructions
— Installation and start-up should only ever be performed by an approved
installer or authorised installation firm.
— Before using the appliance, please read through these instructions
carefully. The manufacturer cannot accept any liability for damage
resulting from failure to follow these instructions.
— Fittings and connections may get hot. Therefore keep children well
The appliance is only suitable for household use and should only ever be
used for heating and drinking water
Operating the appliance
The Electrolux IH Instant Water Heater heats the water as the latter
continuously flows through it. When the hot water tap is opened, the
appliance switches on. When the hot water valve is closed, the appliance
switches off again.
The outlet temperature depends on the respective amount of water flowing
through the appliance and the temperature of the cold water flowing in.
One or more tapping points can be supplied with hot water.
Part ioad switch
Two power levels can be selected by the part load switch.
Position 1: 2/3 power
Preselect this setting for washing hands and
showering in the summer months.
Position 2: full power
For to do the dishs, take a bath or shower.
If the hot water temperature is too low
the flow volume must be reduced.
If the outlet temperature is too high, cold water should be mixed in.
If the flow pressure is too low, select position 2 for a convenient shower.
Hot water flow rate
To ensure its trouble-free operation, the continuous flow heater requires a
specific minimum flow pressure (see technical data on page 6).
If this pressure is to low, the appliance will not switch on. The inadequate flow
pressure may be due to air bubbles being included in the fittings. They must
therefore be regularly cleaned and decalcified.
The hot water outlet temperature fluctuations depend on the season because
of the different inlet temperatures.
Care and maintenance of the appliance
Clean the plastic housing if necessary with a damp cloth and dilute soap
solution. Never use any abrasive, aggressive, and solvent-containing
The Instant Water Heater generally needs no maintenance. Regular
inspection of the appliance by a trained engineer will ensure its operational
reliability and prolong its service life.
Scale deposits in the outlet of fittings reduce the amount of water flow.
The air bubbles of the fittings or hand shower head must therefore be
cleaned from time to time.

*) In addition to the flow pressures of the continuous flow heater itself, con-
sideration must be given to the pressure losses in the household pipe-
The nominal operating pressure is 1MPa. If this value is exceeded, a
pressure reducing valve should be provided in the household pipework.
A safety valve is not necessary.
The bare wire resistance heating system has a high efficiency. Its low
weight and extremely low water content also make it suitable for hard, line-
containing water qualities.
Safety switch
In the event of a fault, the inbuilt safety switch isolates the appliance from
the mains supply on all contacts.
Before the appliance is switched back on, a trained engineer must
ascertain and eliminate the cause of the fault ( see page 17)

Using the appliance for the first time and checking
The unit must be installed and started up by an approved installer which
accepts liability for safety and proper function.
Before the appliance is energised (connected to the electricity supply),
it should be thoroughly flushed with cold water and tightness of the screwed
joints checked.
After the continuous flow heater is energised (connected to the
electricity supply), it should be inspected by a trained engineer to
ensure that it is in proper working order.
Important note: After any work carried out on the water supply unit,
the appliance should also be thoroughly flushed with cold water
(vented) before being switched on again. Only then should the
appliance be reconnected to the electricity supply.
After initial startup, the user should be familiarised with the
operation of the appliance.
The assembly and operating instruction are to be considered and be handed
over to the user for the attention and keeping.
Maintenance and faults (important instructions for the trained engineer)
Electrolux Instant Water Heaters generally require no special maintenance.
To maintain full operational reliability, however, the power- and water-
distributing components should be inspected every 2 years. Specifically the
strainer in the cold water inlet, the water switch unit, the heating system,
and the safety switch should be checked.
