depends of the type of water and its heating temperature. When the
latter is higher than 60°С the quantity of separate limestone
increases. Accumulated limestone impedes the heater efficiency and
may even cause its failure, while increasing the time for water heating.
When using the appliance it is possible to hear some weak noise due to
the water flow through the pipelines and the appliance, as well as to the
natural process of expanding and heating.
When the heater is regularly used to heat water to a lower temperature,
it is recommended to turn the thermostat knob at least once monthly
to its maximum position, then to heat the water to maximum degrees
and keep it such at least for 24 hours. The purpose it to prevent
bacteria growth.
ADDITIONAL CORROSION PROTECTION
Enameled water heater tanks.
In each water heater with enameled
tank is installed additional corrosion protection. It consists of an anode
of special alloy operating only when the water tank is full. The anode is
a consumable (i.e. a device with normal wear during the appliance
operation) and its average operational life is up to 3 (three) years. This
period depends much of the type of operating the appliance and the
characteristics of the heated water. After the period of operational life,
a manufacturer authorized specialist or dealer service company must
check the conditions of the anode. Where necessary it should be
replaced with new one. Compliance with the inspection deadline and
timely replacement of the anode is important for the effective
protection of the tank from corrosion. Both the assessment and
replacement of the anode are not subject of manufacturer and seller
warranty liabilities.
Water heater with enamel tank and anode tester.
The availability of
the anode tester as control device is essential for the heater operation.
Some water heater modifications with traditional thermostat are
equipped with electromechanical anode tester (Fig. 9). It consists of a
arrow-indicating system with a scale and switch (button). The scale
has two sections - red and green. In tank normal operating condition
the tester pointer is in the red section - the tester is not switched on
and the anode is working properly. Checking the anode efficiency is
carried out when the water is fully heated (switched off thermostat, i.e.
the key is not lit) by pressing for few seconds the button on the tester.
The arrow shall depart in the direction of the scale green sector. The
magnitude of the variation is strongly affected by the parameters of the
water and its temperature, as the boundary between the two sectors
correspond to the water average values. The anode efficiency criterion
is its arrow deflection. When at the time of pressing the tester button,
the arrow does not divert or is hold at the beginning of the red section,
you should contact the specialists at your nearest manufacturer or
vendor authorized service company. Their specialist shall review the
tank corrosion protection and repair, if necessary. In some water
heaters modifications the electronic control board indicates the anode
efficiency and degree of wear with periodic regular display blinking.
With advanced wear the size of lighted part decreases. More specifically
the process is described in the additional instruction manual concerning
the electronic control board functions. Once the lighted part of the
display switches off completely you may contact the closest service
company to review and eventually replace the anode.
Water tanks of high quality chrome-nickel steel
. Corrosion protection
and guaranteed long life are secured by correct choice of steel, adequate
design and engineering construction during tank manufacture process.
SERVICE, PREVENTION, MAINTENANCE
In order to secure reliable operation of the water tank in areas with
highly calcareous water it is recommended to clean the limestone
accumulated within. This operation should take place at least once every
two years, while in areas with higher limestone content even more
frequently. The depositions on the enamel coating should not be
removed otherwise than wiped with dry cotton cloth and without using
hard tools. Regular limestone removal and cleaning is particularly
important for appliance reliable operation. It is recommended that
during this maintenance operation you carry out a review of the
enameled tank anode condition. These services are not subject to
warranty coverage and must be performed only by qualified person.
WARNING!
In order to ensure safe and trouble-free operation of
the water heater, the combined valve should be checked regularly for
reduction of its permeability. This is done by lifting the lever, and wait for
30-60 seconds from the side opening the valve to flow thick and strong jet
of water. This operation must be carried out after connecting the heater to
the plumbing and when filling of the tank with water, in the process of
using the heater not less than once every two weeks, as well as
eventually after stop and start of water supply. When at full tank by opening
the valve does not leak or water flow is weak, there is a failure and
probably the valve is clogged by impurities in the sewage. Using water
heater combined with a defective valve is strictly prohibited. Switch off
immediately the appliance from the power supply and contact the nearest
authorized by manufacturer service company. Otherwise, it will cause
damage to the water tank, and could cause tangible and intangible
damages in the room where the water heater is located.
When you are not certain about the temperature in the room where the water
heater is installed, i.e. that it may fall below 0°C, the water from the water
tank MUST be drained - please refer to section 'CONNECTION TO THE
WATER SUPPLY NETWORK’
The water heater outer shell and plastic parts can be cleaned using only a
slightly damp soft cotton cloth and never with invasive and/or abrasive
substances and preparations. Before cleaning the appliance, it MUST be
disconnected from the power supply with the additional disconnection device
or by unplugging the plug on the power cord. IT IS FORBIDDEN to clean the
appliance with steam generator. Particular attention should be paid to prevent
wetting of the appliance light switch on its control panel. The water heater may
be switched on in operation only after complete removal of moisture.
The rules for checking the corrosion protection and anode replacement
(please refer to previous section), as well as removal of the accumulated
limestone, must be strictly observed both during and after the appliance
warranty period.
During the appliance usage and maintenance do not damage the metal
plate with its technical data and serial number. Should you take it off, keep it
with the warranty form because it is the document serving to identify the
water heater.
FAILURES
When the heater does not heat the water, check if the external disconnecting
device is not switched off, if the lighting key is switched off and if the
thermostat knob is not turned to the lowest position.
If the power supply is in order, the lighting key is switched on and the
thermostat knob is turned to its highest position, but the water in the
appliance is still not warming (it is possible that the lighting key or the signal
lamp are lighted or not), using the external disconnecting device unplug the
heater and contact the nearest authorized service company.
In case when from the mixer at completely open tap for hot water there is no
leakage or water flow is weak, check if the filter at the mixer outlet is not
clogged, or whether the shut-off valve before the heater is not fully or
partially closed (4, Fig. 2), or if water supply is not stopped. If all listed above
causes are not the cause of failure, using the external disconnecting device
unplug the heater and contact the nearest authorized service company.
When the water heater is equipped with electronic control board, at the end
of the additional instruction manual are listed the error messages appearing
on the display in case of failure and what measures to take for each case. In
any other general case of failure, using the external disconnecting device
unplug the heater and contact the nearest authorized service company.
In case of failure of the power cord and/or plug for water heaters with such,
contact the nearest authorized by the manufacturer service company as the
cord with plug must be replaced by the manufacturer, its service agent, or a
person with similar qualifications in order to avoid danger.
