Thank you for choosing MEC from LVI. We are certain you will be
very pleased with your new radiator and find it extremely useful.
1. Installation
Diagram 1.
The wall brackets supplied are securely fixed in posi-
tion on the wall using the enclosed screws.The brackets should be
positioned approx. 10-15 cm from each end of the radiator. Note
that the brackets can be used to measure the height.
Diagram 2.
It is important to mount the radiator horizontally in
order for it to function correctly.The connector housing should be
placed as per diagram 2 and the minimum distance specified there
should be carefully observed. The radiator must not be placed
directly underneath a fixed wall socket or in a position where a
person using a bathtub, shower or swimming pool can come into
contact with live parts, e.g. the switch.
Diagram 3.
When the radiator is delivered with a terminal box
and a 5-pole plug, it should be connected by a suitably qualified
electrician. The terminal box is best positioned behind the radiator.
The terminal box has break-off openings for a conduit box, wiring
tubes and an external cable. Please refer to the wiring diagram on
the terminal box lid for the connection of the radiator.
Slave connection
Every radiator can be used as a master or slave radiator. For slave
operation, the radiator is to be connected on terminal blocks 2
and 4 in the terminal box. Thus, the thermostat is by-passed and
the slave radiator’s heat output is regulated by the thermostate of
the master radiator or a central control system. The total output
one master radiator can regulate, including itself, is 2300 W. When
a radiator with thermostat is connected as a slave radiator, the
green light will not indicate when the radiator is working.
Temperature reduction
The temperature set by the thermostat knob can be reduced
either manually or automatically with the MEC-radiator. Set the
thermostate knob at or to choose the manual or automatic
option. For the manual option , no special connection is re quired
in the terminal box. For the automatic option , a control con duc-
tor has to be connected on terminal block 3 in the terminal box.
It is also possible to have the temperature reduction of several/
all radiators in a building regulated by a central timer. The con-
trol conductor must be connected so that it receives N potential
when a temperature reduction is required (controlled N conduc-
tor). If you do not want to use a timer control, a permanently
connected N conductor can be used instead of the control con-
ductor. Temperature reduction is then connected/disconnected by
turning the dial from 0 to the re quired reduction temperature
for the times when you want a lower temperature and when it
should return to normal again. It is important that the phase and
N conductor are correctly connected.
Control system
When using a control system, which controls the room tempera-
ture, the radiator’s thermostat should be by-passed. Do this by
connecting the radiator as a slave radiator (i.e. the power supply
should be connected to the terminal strip 2 and 4).
Note!
If the model designation ends with a P, the radiator is deliv-
ered with an earthen plug and is to be connected to an existing
wall socket. Centrally controlled temperature reduction and slave
connections cannot be used in this version.
Diagram 4.
The enclosed plastic hook can be fitted to the wall to
coil up any surplus cable. (4A). It is very important that the plug
is pushed fully into position in the terminal box. (4B) The top of
the wall bracket can be pulled up and locked in its top position to
make it easier to mount the radiator. (4C) Make sure that the top of
the bracket is securely fitted into the slots in the frame.
2. Operation
Diagram 5.
At the top of the control section, inside the transparent
cover, there is a switch for turning the radiator on and off. The radia-
tor it turned on by setting the switch into position I. (5A)
The thermostat knob below the switch is used to select a room
temperature between 10°C to 30°C. At the lowest setting (
*
), you
achieve a frost protection temperature of about 7°C. The green light
indicates that the radiator is working with full output. Thus, it flashes
according to the required heating. (5B)
With the knob below the thermostat knob, you select between the
following temperature reduction options:
= no temperature reduction. The temperature is the one select-
ed by the thermostat knob, even if control equipment is set for
reduction.
= temperature is constantly reduced by -3,5°C in relation to
the temperature selected by the thermostat knob, but can never
drop below the frost protection temperature.
= temperature reduction is automatically switched on and off
by external control equipment. The reduction temperature can be
selected between 0°C and -15°C. The frost protection temperature
(7°C) is always the lowest possible room temperature. (5C)
With the lowest knob, the radiator’s maximum surface temperature
can be selected.
Setting N:
the radiator’s surface temperature reaches a maximum of
80°C.
Setting L:
the radiator’s surface temperature reaches a maximum of
60°C. In this setting, you obtain about 50% of the thermal energy
as compared to setting N. This should be taken into consideration
when rating the power dimensioning. (5D)
Diagram 6.
The transparent cover over the regulations can be locked
to prevent the radiator controls being tampered with.
3. Maintenance
Use only mild detergents for cleaning and wiping of the radiator.
4. Miscellaneous
The radiator’s overheating protection disconnects the current if the
radiator becomes too hot. The radiator is reset by switching off for
about 15 minutes. If the radiator repeatedly disconnects, check that
no parts of the radiator are covered. Otherwise contact a suitably
qualified electrician or the manufacturer.
“Do not cover” means that the radiator must not be used for
drying clothes, for example, by placing them directly on the radia-
tor.
This radiator is filled with an exact amount of environmentally
friendly vegetable oil. Any repairs that require the radiator to be
opened shall therefore only be carried out by the manufacturer or
its approved agent. Please contact the manufacturer or its approved
agent in the event of a leakage.
There is a selection of accessories including different control sys-
tems and a securing plate for the wall bracket. For double MEC
radiators, there are top grids and side plates as accessories. (See
picture 4)
The radiator is currently backed by a 2-year warranty.
Please contact the manufacturer or an authorised electrician if you
have any problems or need any repair work to be carried out.
