Appliance function
The fully electronically controlled ELECTROLUX IH instant water heater is a
pressurised appliance for the supply of one or more tapping points and heats
the water as the latter continuously flows through it. A flowrate sensor switches
on the heating at a flowrate of around 3 l/min and off again at around 2,5 l/min.
The microprocessor controlled electronic system automatically adapts the
heating power with regard for the inlet temperature, the temperature set on the
temperature selector knob, and the water flowrate. The user thus has hot
water available in an energy-saving system giving the exact temperature required
without any time limitation whatever.
The nominal operating pressure is 1 Mpa. 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, lime-containing
water qualities.
Safety temperature and pressure limiter
In the event of a fault, the inbuilt safety
temperature limiter 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). Then
carefully press in the contact rocker with a
screwdriver until it audibly engages.
Important! The safety temperature and pressure limiter should never
be adapted or modified in any way!
Important: Don't block up the contact rocker!
