Electric installation
Afterthe connection towater and electric networkthe heater is ready for use.

By turning the knob
of
thermostat
at
the front side
of
the protecting cover, the wished
temperature ofwaterbetween
25°C
and
75°C
is chosen. We recommend theadjustment
of
the knob to the position "E". Such an adjustment is the most economic; with
it
the
temperature
of
water shall
be
about
55°C,
the excretion
of
lime-stone and thermal loss
shall be smalleras
by
adjustmentto highertemperature.
The operation
of
electric immersion heaters isshown
by
pilot light. Onthe perimeter
of
the
water heaterthere is a built-in thermometer which isshowing the temperature ofwater.
When the heater shall not
be
used during a longertime, its contents must
be
protected
against freezing so that the power supply (electricity) shall not
be
switched off, but the
thermostat knob shall beadjusted to the position "*".With this adjustmentthe heatershall
maintain the watertemperature byabout 10°c. But when the heater is switched-off from
the electric network,
at
risk forfreezing, the watermust
be
emptied from it.
Before draining water heater should be disconnected from main supply. Than hot water
valves on taps should beopened. Water heateristo be drained through inletconnection.
Forthis purpose it is recommendable to put special fitting or a drain valve between inlet
connection of water heater and safetyvalve. If this is not the case water can be drained
directly through safety valve by putting the lever
or
screw cap
of
safety valve
to
"Test"
position. Afterdraining through inlet pipethere issmall quantity
of
residual waterwhich is
to be drained bytaking off
of
heating flange."
The outside
of
thewaterheater is cleaned
by
a mild solution
of
detergent. The solvents
or
rough cleaning means should not be used.
By regular service
check
of
impeccable operation must
be
assured and a long lifetime
of
the water heater. The first
check
must be performed byan authorised service workshop
after about two years after the first connection. At check, the use
of
anti-corrosion
protecting anode is checked and if necessary lime stone must
be
cleaned which with
regard to the quality, quantityand temperature
of
the waterused is gathered in the inside
ofthe water heater. Service workshop shall after check recommend also the date
of
next
check
of
the water heaterwith regard tothe established results.
Never try
to
repair any possible faults
of
the
water heater by yourself, but inform
about it the nearest authorised service workshop.
