7 MAINTENANCE

Gabarrón electric boilers do not need any special maintenance, only the following should be checked:
-Check the pressure indicated by the pressure gauge frequently, ensuring that it is between 1 and 1.5 bar when cold.
- Never start the boiler when it is empty.
- Never start the boiler when the S.H.W. tank is empty; to fill it for the first time open a hot water tap and wait until
water comes out of it.
-Precaution against freezing. In dwellings that are frequently unoccupied or at risk of freezing, an anti-freeze of the
appropriate quality can be added to the water of the heating installation – the concentration must not exceed 30%
in volume.
- Clean the surfaces of the boiler with a damp cloth, having previously disconnected it from the mains. Do not use
solvents or abrasive products.
