TECHNICAL INFORMATION Electrical accumulation water heaters are designed to work with pressure of the water supply pipeline. The appliance is not meant for persons (including children) of reduced psychophysical abilities, unless under supervision of persons responsable for their safety, i.e. for persons not skilled for use of the appliance. Improper use of the appliance, especially from the side of children, should be prevented.

Water heaters are made according to valid standards and tested and certied by

authorized laboratory. Product technical characteristics are given on the sticker „Table with Characteristics“ between connection pipes.

INSTALLATION Only authorized persons are allowed to perform installation / connection of water

heaters to water and power supplies. All types of water heaters are xed to the

wall by 2 or 4 screws of 8 mm minimum diameter. Thin and delicate walls should be reinforced prior to water heater installation

The tank is insulated with quality polyurethane insulation providing that water stays hot

for long. Enamelled tanks are extra protected from corrosion by the magnesium anode.

Water from enamelled and stainless steel tanks is physiologically pure and therefore usable also for food preparation.

Left water heater MB 80 HL Right water heater MB 80 HD

Horisontal water heaters could be mounted as left or right depending on the position of the thermoregulator, and this models are designed to be mounted only on wall (not ceiling ) ,

so pipes are toward oor.

Page 8

Input of cold water for electrical water heater is marked with blue ring, while hot water output is marked with red ring, which is to be respected when connecting water heater to water supply. Accumulation heater works under preassure (closed system) and it is possible to use water at more than one point in the house.

The ttigns/mixing pipes appropriate for work under pressure have to be used with this water

heater. On each accumulation water heater there have to be mounted a safety valve (see Picture 3)

to keep pressure in the tank from exceeding the limit. Such safety valve should be checked

every two weeks. By moving the lever or unscrewing the nut (depending on valve type)

exceeding water from return safety valve should come out meaning the valve is working

correctly. Non-return valve prevents tank to empty in case of pressure fall in water supply pipeline. If regular water pressure in the pipeline is higher than 0,6 Mpa (6 bar) a reduction valve has to be mounted on the cold water inlet connection.

CONNECTION TO WATER SUPPLY

1. Safety valve

2. Test valve

3. Non-return valve

4. Reduction valve

5. Interlocking valve CW cold water HW hot water

An interlocking must not come between the safety valve and the water heater, as it would disable safety valve function. Fill the water heater with water before connecting it to electric

power supply. During the lling operation open the hot water pipe. When water starts coming

out the hot water pipe the water heater is full.If hot water is used on more than one spot in the house it is recomandable to make internal pipeline as short as possible so that heat losses are minimum.

The water heaters with heat exchanger are connected to water supply in the same way like regular water heaters. Water heaters with heat exchanger are ment for connection to other

energy sources (centralized heating system, solar heating and heat punps). Entrance point

of heated media to the heat exchanger is marked with red, while exit is marked with blue. Water heating with electrical heater and heat exchanger could function contemporary or separately. Water heaters with heat exchanger are not designed for central heating systems which uid temperature exceeds 110°C. Due water heating, water pressure

in water heater increas up to safety valve set limit, and water drops come out the valve. The drip can be piped to the drain by installing a catching unit just below the

safety valve.In case the existing plumbing does not enable you to pipe the dripping water

Page 9

from the return safety valve into the drain, you can avoid the dripping by installing a 3-litre

expansion tank on the inlet water pipe of the boiler. Water may come out in drops from the exhaust pipe of pressure reduction device i.e, safety

valve, this pipe has to be open and positioned downwise, to prevent freezing of the water in the pipe. By regular function of the safety valve it should be possible to remove limescale sediment as well as to check if it is bloacked. Safety valve is delivered with the water heater and the sheme shows how to install it. At installation of a water heater and its connection to water supply, it is recomanded to use new set of hoses, old ones should not be used. CONNECTION TO POVER SUPPLY Electric accumulation water heater is connected to power supply by valid standards for

electrical installations, with a plug cable 3x1,5 mm H05VV.

Before connecting power supply cable, unscrew the two screws and remove protection cap of the electric water heater. The electric water heater is not delivered with a device to cut off the power from the supply permanently. A separating element of all the poles from the supply should be included, according to local installation rules. Such separating means have to be included in the electrical installation.

1. Thermoregulator

2. Heater

3. Connection clamp

4. Signal lamp L – phase N neutral Ground

WARNING: Before any intervention the water heater must be disconnected

from the power supply line.

USE, CONTROL, MAINTENANCE OF ELECTRIC WATER HEATERS

After connecting it to water and power supplies the water heater is ready to use. For types

without external heater regulation (no button on the cover), water temperature is regulated

by a preset thermoregulator. It is recomanded not to change the set temperature (t=55°C) being optimal for saving energy and minimum limestone sedimentation. Should the user

however want to change the temperature of water heating, the water heater should rst be

disconnected from power supply line, protection cap on the bottom should be taken off, and by turning plastic button directly on the thermoregulator, water heating temperature can be set to be lower or higher within the range 20 to 70±5°C.

Page 10

For water heater types with external regulation, by simple turning the button desired

water heating temperature can be set within the range 20 to 70±5°C. When desired/ set temperature is reached inside the the tank the thermoregulator will cut the power circuit automatically, and the signal lamp which has been on during the heating time, will go off.

WARNING: before using hot water from water heater turn it off from elecrical power

supply.

Water heaters also have thermometers with metal cap and bimetal showing the temperature of the water. If water heater will not be used for longer period it is recomanded to disconnect it from power supply line. If water inside the water heater could freeze while not used it is recomanded to empty the tank. The miantenance tips should be respected, especially check-up for how much Mg anode is consumed, at least every 36 months, and replace it if needed. The limestone sediment should be removed regularly. For such interventions tank must be emptied. To empty the tank please proceed as follows:

- Disconnect the water heater from power supply

- Close the inlet cold water valve

- Open the hot water pipe

- Unscrew the safety valve mounted on the cold water inlet, and wait for water to go out.

After that the unscrew the nut of the heater counterange, take out the ange with the heater,

remove the limescale and replace Mganode. If you use chemical products for limescale removal, they must not come into contact with Mg-anode (anode should be taken out).

Afterwards the tank should be rinsed and relled with water.

WASTE DISPOSAL – WHAT AFTER YOUR WATER HEATER IS NO MORE USABLE

The accumulation water heaters and the packing are made of recyclable materials. After your water heater is not usable any more, it is forbidden to dispose it as non-selected waste. For waste disposal, the water heater

plactic and rubber parts should be separated from metal parts, classied

and left for recycling or

nal disposal according to loacal regulations.Only by waste separation and

management you will protect the environment.
