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 re-

place it if needed. The limestone sediment should be removed regu-

larly. 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 counterflange, take out 

the flange with the heater, remove the limescale and replace Mg-

anode.

If you use chemical products for limescale removal, they must not 

come into contact with Mg-anode (anode should be taken out). Af-

terwards the tank should be rinsed and refilled 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 heat-

er 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, classified and left for recycling or 

final disposal according to loacal regulations.Only 

by waste separation and  management you will pro-

tect the environment.
