10 Instructions for use and maintenance

•

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 (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.

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.

V. 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.
