1 Function of an Electrical Convector

A convector is a heating device the function of which is based on conversion
of electrical energy into heat and on the upward flow of warm air. It uses traditional
principles of electrical heating and the chimney effect in an advanced combination.

Thus, an electrical conveyor forms something like a small chimney fitted with
an electrical heating element in its bottom part. The element heats air which then
flows upwards inside the convector and into the room it is heating. Cooler air drops
down, the convector “takes it in”, reheats it and returns it back to into the room.
Therefore, we can call the convector a “chimney radiator”, which can function
without a fan, silently and efficiently. To achieve a pleasant temperature in a room,
only minimum consumption of 30 W per cu.m is required.

Te convector is a modern version of the tried-and-tested hot-air heating.

The convector is equipped with a thermostat for controlling the required room
temperature between 5°C and 30°C. If more than one convectors are used connected
to an independent power supply, the temperature can be regulated by a central room
thermostat or a programmable regulator. The convector is fitted with a thermal fuse
which cuts out the power supply to the convector in case of overheating.

3 Use

The electrical convector can be used:

- as an additional heating device to a current heating system (it can be easily plugged

into an electrical socket)

- for comprehensive heating of flats, houses, offices, etc. at the attractive electricity

rate BP.

4 Location and Installation

The convector is designed to be used in a normal environment AA5/AB5 as
per ČSN 33 2000-3 and ČSN 33 2000-5-51 (i.e. ambient temperature + 5°C to +
40°C, humidity – depending on temperature – up to max. 85%). The wall on which
the convector is mounted must be non-flammable (non-flammable materials classified
in group A as per ČSN 73 0832). The convector must not be installed in rooms with a
bath, bathrooms, wash rooms and showers, in zones 0, 1 and 2 as per ČSN 33 2000-7-

701. It may not be installed also in zones 3 if there is a possible occurrence of water
jets used for cleaning in municipal spas (municipal spas are baths and showers used in
schools, factories, sports clubs, etc., including any other such facilities for public use).

If used in zone 3, extra local interconnection must be done as per ČSN
33 2000-7-701.

Convector must not be installed directly under the mains plug !

Wiring to a power mains and electrical installation must be performed only by
an authorized person, qualified under Regulation No. 718/2002 Z.z.

Colour coding of conductors (to the fixed terminals in the preinstalled flush­mounted wall conduit box):

protective conductor – yellow-green
central conductor – light blue
phase conductor - brown
Electrical convector control is designed to be operated by persons without any

electro-technical qualification. The person operating the convector may adjust only
the controls specified in these Operating Instructions!

Assembly – suspension on a wall is depicted in Fig. 3.

Fig. 3: Wall mounting

In order for the convector to function to your absolute satisfaction, the
following conditions must be met:

- it must be mounted (we recommend suspended on a wall) so that the bottom edge

is at least 15 cm above the floor,

- the convectors bottom and top openings must be free of obstacles to allow for

unobstructed circulation of air,

- foreign objects (furniture) must not obstruct air circulation, and must be located at

least 20 cm from the front, top and side walls of the convector.

5 Operation
Start the convector by switching on the power switch (see Fig.2). Set the

thermostat controller to the maximum temperature position. Heat the room until the
required temperature is achieved (check the room thermometer). Then turn the
thermostat controller back towards a lower temperature until the convector switches
off. Leave the thermostat in this position. The room temperature shall automatically
be maintained at the selected value.

Caution:
During the first start up of the convector a slight odour might be perceived,

which is caused by the burn-off of residues inside the convector. After longer time of

not using convector (summer, holiday ....) after restarting up it could appear slight

dour caused by the burn-off dust on the heating elements.

Maintenance

The convector is fitted with a fuse that cuts out the power supply to the
heating element in case of convector overheating. This condition could arise only if
you prevent the free circulation of air through the convector (unsuitable location of

Failure and Repair

The convector does not require any special maintenance. We recommend
normal cleaning of the surface with a moist cloth and detergent. The convector

Delivery

In case of convector failure, first check that the convector switch is turned on,
and that the convector is plugged into a power socket. If it is, then check the
thermostat setting and free circulation of air. If these measures do not h
