Dear buyer, we thank you for purchase of our product.
PRIOR TO INSTALLATION AND FIRST USE, PLEASE CAREFULLY
READ THESE INSTRUCTIONS
This water heater has been manufactured in compliance with the relevant standards
and tested
by the relevant authorities as indicated by the Safety Certificate and the
Electromagnetic Compatibility Certificate. Its basic technical properties are stated upon
the nameplate, glued between theconnection pipes. The water heatermay be connected
to water and electric power supply only
by a qualified specialist. The reach in its inside
due tothe repair or removal of limestoneand checking and replacement of anti-corrosion
protection anode may be performed only
by an authorised serviceworkshop.
BUILDING-IN
The water heater shall be built as close as possible to the outlets. It has to be fitted to
the wall using appropriate rag bolts with minimum diameter of 8 mm. The walls with great
portabilitymust beat placewherethewaterheatershall hanged up be suitablyreinforced.
Due the universal construction the waterheater it can be fixed vertically
on the wall or
horizontally on the wall (output pipes must be on the left).

CONNECTION TO THE WATER SUPPLY
Inletand outlet ofwaterare on thewater heaterpipes markedwith colour. The supplyofcold
water is marked with blue, the outlet of
warm waterismarked with red. The water heatercan
be connected to the water supply in two manners. Closed pressure system of connection
enables the outlet ofwater on
several outlet spots, non-pressure system enables onlyone
outlet point.
With regard tothe system ofconnection chosen, also the suitable mixing taps
must be purchased. By open non-pressure
system it must before the water heatera non-
retum valve
be built-in preventing the running of water ofthe tank if in the networkthe water
runsshort.
By this system of connection, the cross-flowmixingtap mustbeused. In thewater
heater, due to the heating the volume ofwater is increasing, which causes the dropping of
water ofthe
mixing tap pipe. By strong squeezing of knob ofthe mixing tap the dropping of
water can not be prevented, but the
mixing tap can onlybe damaged.
By closed pressure system ofconnection on the outlet spots the pressure mixing tap must
be used. For safety reasons the supply pipe must be fitted with a return safety valve or
alternatively, a valve ofthe safetyclassthat preventsthe pressure in thetankfrom exceeding
the nominal pressure bymorethan
0.1 MPa.
The heating
of water in the heatercausesthepressure in the tank to increasetothe level set
bythe safety valve. h. the water cannot return to the water supplysystem, this can result in
the dripping from the outlet ofthesafety valve. The dripcan be piped to thedrain by installing
a catching unit just belowthe safety
valve. The drain installed below the safety valve outlet
must be piped down verticallyand located
in the environment that isfree from the onset of
freezing conditions.
In case the existing plumbing does notenable you to pipe the dripping
water
from the return safety valve into the drain, you can avoid the dripping by installing a
3-litre expansion tankon the inletwater pipe ofthe boiler.
You should ensure that the return safety valve is functioning properly by checking it on a
regularbasis i.e. every14
days. To checkthe valve, you should openthe outlet of the return
safetyvalve
by turning the handle or unscrewing the nut ofthe valve (depending on the type
of the valve). The valve is operating properly if the water comes out of the nozzle when the
outlet is open.

5-Closingvalve T - Hotwater
Between the water heater and non-return valve no closing valve may be built-in
because it would disable the operation of non-return safetyvalve.
The water heater may be connected to the water supply in the house without reduction
valve if the pressure in the network is lowerthan 0.5 MPa If the pressure in the network
surpasses 1.0 MPa, two reduction valves must be built-in, one afteranother.
Priorto
the electric connection, thewaterheater must mandatorily be filled with water. By
first filling the tap for the hotwaterupon the mixing tap must be opened. When the heater
is filled with water,
the waterstarts to run through the outlet pipe of the mixingtap.
CONNECTION OF THE WATER HEATER TO THE ELECTRIC NETWORK
Prior to the connection to electric networkin the water heaterthe connecting cable must
be built-in, for it the plate must be removed inserted in the front side of the plastic cover.
The plate is released
so that in theslotbetween inserting plate and protecting cover at first
at the knob of thermostat and than on the side opposite the knob, cautiouslya screwdriver
is pushed. When the plate is removed from both sides, it can
be removed by hand. In
order to take off the protecting plastic cover, also the thermostat knob must be removed
and both fixing screws screwed off. The replacement
of protecting plastic cover is done
in reversed order.
The connection
of the water heater to the electric networkmust be performed according
to standards for electric installation. Because the water heater has no component which
would permanently separate it from the electric network, upon the cable connection
between itand permanent installation a switch must be installed which breaks both power
supplypoles having between the opened contactsa gap at least 3 mm wide.
CAUTION: Prior to each reach in the inner of the water heater it mustabsolutely be
disconnected from the electric network!

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.
