7. Important rules
The use of the appliance for any purpose other than that it is intended is prohibited.
Do not switch on the water heater unless you checked that it is filled with water.
The installation and maintenance must be carried out by a professional from the sector
in accordance with manufacturer’s instructions.
The water heater must only be installed in premises with normal fire resistance. There
should be a siphon connected to a plumbing drainage. The premises should be protected
from freezing and the temperature should never be lower than 4 °C.
Qualified P&P specialists and Electricians must only perform the connecting of the water
heater to the water supply and electric mains.
If the probability exists for the premise’s temperature to fall below 0°C, the water heater
must be drained via raising the safety return-valve’s lever.
During use (water heating mode), the dripping of water from the safety return-valve’s
drainage opening is normal. The same must be left open to the atmosphere.
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 service is not provided under warranty maintenance.
If upon turning the valve’s knob when the water tank is full, water do not start running
from the valve’s drainage opening, this is a signal of malfunction and the appliance’s use
must be discontinued.
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
It is necessary to maintenance the water heater regarding the described rules, to change
duly the anode protector and to clean the limestone also after the warranty period.
It is necessary to keep the rules for preventive maintenance, replacement of magnesium
anode protector and cleaning even after guarantee period.
Usage of this device at temperature and pressure level above prescribed leads to
warranty violation!
This device is intended for heating of potable water in liquid state. Using different fluids
in different states leads to warranty violation!
8. Periodic maintenance
Under normal use of the heater, under the influence of high temperature, lime scale, the so-
called lime scale layer, is deposited upon the heating element’s surface. This worsens the heat
exchange between the heating element and water. Due to these facts, the manufacturer
recommends preventive maintenance of your water heater every two years by an authorized
service center or service base. This protective maintenance must include cleaning and inspection
of the anode protector (for water heaters with glass-ceramic coating), which shall be replaced
with a new one if needed. Each preventive maintenance of the said type must be entered in the
appliance’s warranty card and must outline date of performing the preventive maintenance,
company performing the preventive maintenance, name of person performing the preventive
maintenance, and signature.
Non-fulfillment of the above requirement may terminate the free of charge maintenance of your
boiler.
The manufacturer does not bear the responsibility for all consequences caused by not
obeying the instructions, given hereby.
