Description And Principle Of Work; Mounting And Switching On - TESY GCV7/4S Instructions For Use And Maintenance Manual

•
In order to secure the water heater's safe operation, the
EN
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.

DESCRIPTION AND PRINCIPLE OF WORK

IV.
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 (boiler tube). The boiler tube'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.

Instructions for use and maintenance
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 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.

MOUNTING AND SWITCHING ON

Qualified technicians must perform all technical and
electrical assembly works. A qualified technician is a
person who has the competence according the regulations of the
country in question.
1. Mounting
We recommend the mounting of the device at close
proximity to locations where hot water is used, in order to
reduce heat losses during transportation. In the event the
device is mounted in a bathroom, the selected location
must exclude the possibility of water spray contact from
the showerhead or portable showerhead attachment.
The appliance is affixed to a wall via the mounting
brackets attached to the unit's body (if the brackets are
not attached to the unit's body, they must be affixed in
place via the provided bolts). Two hooks are used for
suspending the appliance (min. Ø 10 mm) set firmly in the
wall (not included in the mounting set). The mounting
bracket's construction designed for water heaters
intended for vertical mounting is universal and allows a
distance between the hooks of 220 to 310 mm (fig. 1a).
For water heaters intended for horizontal mounting, the
distances between the hooks vary for the different models
and are specified in the table 1 to Fig. 1b.
In order to prevent injury to user and third persons in
the event of faults in the system for providing hot
water, the appliance must be mounted in premises outfitted
with floor hydro insulation and plumbing drainage. Don't
place objects, which are not waterproof under the appliance
under any circumstances. In the event of mounting the
appliance in premises not outfitted with floor hydro
insulation, a protective tub with a plumbing drainage must
be placed under the appliance.
