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 modifications to the water heater's construction
and electrical circuitry are forbidden. If such alterations or
modifications are found during inspection, the appliance's warranty
shall be considered as null and void. Alterations and modifications
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.
•
These instructions also apply to water heaters equipped with a heat
exchanger.
•
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
qualification, to avoid any risk.
•
