The purpose of the technical description and operation manual is to acquaint
you with the product and the conditions of its proper installation and use. These
instructions are also intended for quali ed technicians who will perform the initial
installation or disassembly and repairs in the event of a breakdown.
Please consider that adherence to the present instructions will primarily be
of interest to the consumer, but along with this, it is also one of the warranty
conditions, speci ed in the warranty card, so that the consumer can bene t from the
free warranty services. The producer is not responsible for damages of the appliance
resulting from operation and/or installation which are not in compliance with the
instructions in this manual.
The electric water heater conforms to the requirements of EN 60335-1, EN 60335-2-21.
I.
INTENDED USE
The appliance is intended to supply hot water to households equipped with a piping
system with pressure below 6 bar (0.6 Mpa).
It is designed to operate only in closed and heated premises where the temperature
is not lower than 4°C and it is not designed to operate in a continuous protracted
regime. The appliance is designed to operate in regions where the water hardness
is not more than 10°dH. If it is installed in a region where the water is harder, it is
possible limestone precipitation to accumulate very fast. This can cause speci c
IMPORTANT RULES
III.
•
The water heater must be mounted only in premises with normal re resistance.
•
Do not switch on the water heater unless you have ensured that it is lled with water.
ATTENTION! IMPROPER INSTALLATION AND CONNECTION OF THE APPLIANCE WILL MAKE IT HAZARDOUS WITH
GRAVE HEALTH CONSEQUENCES AND MAY CAUSE EVEN DEATH OF USERS. IT MAY ALSO DAMAGE THEIR PROPERTY,
THAT OF THIRD PARTIES, AS A RESULT OF FLOODING, EXPLOSION, FIRE. Installation, connection to the water mains
and connection to power lines must be carried out by quali ed technicians. A quali ed technician means a person
who has appropriate competencies pursuant to the regulations of the relevant state
•
Upon connecting the water heater to the electric mains care must be taken to correctly connect the
safety lead (for models without power cord with a plug).
•
If it is likely for the temperature in the room to fall below 0°C, the water heater must be drained (follow
the procedure described in section V, subsection 2 ''Water heater's piping connection"). For models with
possibility for adjustment, anti-frost mode can be used following the conditions in section VII.
•
During use (water heating mode), dripping of water from the safety return-valve's drainage opening is
normal. The latter must be left open to the atmosphere. Measures should be taken to lead and collect the
leakages in order to prevent damages, ensuring that this meets the requirements described in item 2 of
section V.
•
During heating the appliance may produce a hissing noise (boiling water). This is normal and does not indicate
any damage. The noise gets louder with time and the reason for this is the accumulation of limestone.
•
To remove the noise the appliance must be cleaned from limestone. This type of cleaning is not covered
by the warranty.
•
In order to secure the water heater's safe operation, the safety return-valve must undergo regular
cleaning and inspections for normal functioning (the valve must not be obstructed), and for the regions
with highly calcareous water it must be cleaned from the accumulated lime scale. This type of cleaning is
not covered by the warranty.
All alterations and modi cations to the water heater's construction and electrical circuitry are forbidden. If
such alterations or modi cations are found during inspection, the appliance's warranty shall be considered
as null and void. Alterations and modi cations mean the removal of elements incorporated by the
manufacturer, incorporation of additional components into the water heater, replacement of elements by
similar elements unapproved by the manufacturer.
•
If the power supply cord (of models that have one) is damaged, it must be replaced by a service
representative or a person with similar quali cation, to avoid any risk.
•
This appliance can be used by children of 8 years of age and above, and also by persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they are supervised or
have been instructed about the use of the appliance in a safe way and understand the hazards involved.
•
Children should not play with the appliance.
•
Cleaning and user maintenance should not be performed by children without supervision.

noise during heating, as well as fast damaging of the electrical part. For regions
with harder water yearly cleaning of the limestone precipitation in the appliance is
recommended, as well as usage of not more than 2 kW of heating power.
