•
The valve and the elements linked to it must be protected from freezing.
•
During the heating the appliance could produce a hissing noise (the boiling water).
This is common and does not indicate any damage. The noise gets higher with the
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 service is not provided under warranty
maintenance.
All alterations and modifications to the water heater's construction and electrical
circuitry are forbidden. If such alterations or modifications are established during
inspection, the appliance's warranty shall be null and void. Alterations and
modifications shall mean each instances of removal of elements incorporated by the
manufacturer, building in of additional components into the water heater, replacement
of elements by similar elements unapproved by the manufacturer.
•
These instructions shall 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.
•
This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory or mental capabilities or lack of experience and
knowledge if they have been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved.
•
Children shall not play with the appliance.
•
Cleaning and user maintenance shall not be made by children without supervision.
IV. DESCRIPTION AND PRINCIPLE OF WORK
The appliance consists of a body, flange at the bottom side /for water
heaters intended for vertical mounting/ or at the sides /for water
heaters intended for horizontal mounting/, protective plastic panel
safety-return valve.
1. The body consists of a steel reservoir (water tank) and housing
(outer shell) with thermal insulation placed in-between made of
ecologically clean high density polyurethane foam, and two pipes with
thread G ½ '' for cold water supply (marked by a blue ring) and hot
water outlet pipe (marked by a red ring).
•
The inner tank may be of two types depending on the model:
Made of steel protected form corrosion by a special glass-ceramics
•
coating
Made of stainless steel
The vertical water heaters may be outfitted with a built in heat
exchange unit (serpentine tube). The heat exchenger's entrance and
exit are located at the sides and represent pipes with thread G ¾ '' .
2. The flange is outfitted with: electric heater and thermostat.
The water heaters with glass-ceramics coating are outfitted with a
magnesium protector.
The electric heater is used for heating the water in the tank and is
managed by the thermostat, which automatically maintains the set
temperature.
The thermostat has a built in overheating safety device, which switches
of power to the heater when the water temperature reaches excessive
values.
3. The safety-return valve prevents the appliance's complete
emptying in the event the cold water supply is interrupted. The
valve protects the appliance from pressure increases higher than the
English
allowed value during heating (! pressure increases upon an increase
of temperature), via release of excess pressure during the drainage
opening.
The safety-return valve cannot protect the appliance in the
event of water mains pressure in excess of the acceptable
pressure stated for the appliance.
V. MOUNTING AND SWITCHING ON
Attention! Improper installation and connection of the
appliance may make it hazardous for the health and life
of consumers. It may cause grievous and permanent
consequences, including but not limited to physical injuries and/
or death. Improper installation and connection of the appliance
may also lead to damage to the consumers' property /damage
and/ or destruction/, or to that of third persons, as a result of, but
not limited to flooding, explosion and/or fire.
Installation, connection to the main water and power supply, and
putting into operation must be carried out by certified electricians
and technical personnel certified in installation of this category of
appliances, who have obtained their license in the state where the
installation and commissioning of the appliance are carried out, and in
compliance with its local legislation.
