the connector of at least 3 mm. The water heater should be connected to the network through a fix

connection.

THE THERMOSTAT

This water heater is a rather good quality equipment that is built, controlled and tested thoroughly. Its only

task is to keep and to limit water temperature at a pre-selected value. The water heater thermostat is sealed

and therefore it is forbidden to perform any possible (re)controls or reparations other than the ones executed

in our factory, except for normal control through turning the hands, which can only be performed by a

professional technician after the appliance has been put into operation, in a voltage free state.

Neglecting this instruction leads to losing the allowance of warranty. In case of any difficulties (special

failures), the thermostat should be simply replaced. The water heater should be handled with special care.

In order to ensure economic usage of electric energy, the operation control temperature should be set around

C, so that corrosion resistance should be improved and risk of scale deposit should be reduced. Until

reaching the set temperature, terminals 1-2 are closed, while after reaching the set temperature, terminals 1-3

are closed.

THERMIC SAFE SEPARATION OF THE HEATING CIRCUIT

The thermal safety of the water heater should be provided in the boiler circuit!

ANODE PROTECTION

- As a supplementary accessory, the hot water tank is equipped with an active anode to protect it

against corrosion. The life expectancy of the active anode depends on the conditions of water and operation.

The state of the anode has to be checked during periodic maintenance measures targeting scale removal or at

least in every second year.

- The date of repeated check is defined by the repair technician. If the diameter of the anode shrinks to

10 mm at any points, it has to be replaced.

- The replacement of the active anode can only be performed by a contracted service shop (see the

commercial warranty!).

- After the replacement of the active anode, its earthing has to be set according to its original state.

- It is extremely important to ensure a good metal contact between the active anode and the earthing

screw.

IN CASE OF NEGLECTING THE ABOVE INSTRUCTIONS THAT CAUSES DAMAGE TO

SAFETY AND USAGE FEATURES OF THE WATER HEATER, YOU LOSE YOUR GUARANTEE

AND WARRANT RIGHTS.

MAINTENANCE

Practically, the water heater does not require any maintenance. In case of locations where the hardness of

water is above average, it is recommended to remove scale from the appliance every year according to the

followings:

- The water heater should be annealed from voltage and the tank should be separated from the cold

water pipeline system through closing the closing valve.

- The water should be drained from the water heater through opening the combined safety valve in a

way that a hot water tap is opened in the same time, then the electric parts should be disassembled. Then the

screws of the closing cover should be removed, as well as the closing cover itself.

- The scale deposited in sedimentary or laminar form should be removed from the tank and the parts

of the appliance should be cleaned carefully. The wall of the tank should not be harmed as it is equipped with

an effective anti-corrosion protection.

- After cleaning, the closing cover and the electric parts should be assembled back with a new sealing,

then earthing should be mounted and electric connection should be performed.

Then the process of putting the water heater into operation should be performed in the same way as in

the case of putting a brand new water heater into operation.

DRAINAGE IN CASE OF DANGER OF FROST

The water heater should be absolutely drained when it remains inoperative at a location which is exposed to

danger of frost. Therefore:

1. The water heater should be annealed from voltage.

2. The cold water inlet tap should be closed.
