Electric Combination Boiler User Manual 

CARE AND BOILER CLEANING 

 
Regular maintenance is required by expert teams according to the manufacturer's instructions for the 
efficient operation of your system. 

Regular checks: 

 

The water level must always be checked. The pressure gauge must be marked after the first 
filling of the system. When the water is cold, the water pressure level should be checked. If 
the water level or pressure has fallen below the static pressure or system setting, water should 
be added to the system (when the appliance is cold). To protect the system and the device 
from  corrosion,  the  water  to  be  fed  into  the  system  must  be  softened  according  to  local 
settings. 

 

Check the electrical cables for wear, peeling, or a problem due to external influences. 

Cleaning the appliance: 

 

The outer skin panels of the device can be cleaned as required. 

Maintenance: 

Contracted service of the system before each working season; we strongly recommend that you call 
our  authorized  service  to  check  the  device,  installation,  electrical  connections.  Do  not  do  any 
maintenance work without the help of an expert. At least once a year the authorized service must be 
checked and maintained. In electrical devices, loosening of connection points can occur over time. In 
order to avoid any problems, it is appropriate to carry out the aforementioned checks. 

ASSEMBLY 

 

The  boiler  must  be  placed  in  a  protected  place  against 
freezing. Precautions should be taken to prevent water 
from freezing, especially if it is not used for a long time in 
cold areas. 
If the mains water is higher than 6 bar, pressure regulator 
must be placed in the domestic water inlet. If the water 
pressure of the domestic water is less than 0.8 bar, the 
pressure will not be sufficient. 
It is compulsory to place a dirt trap (filter) at the entrance 
of the combi boiler from the radiators. The strainer will 
prolong the life of the combi boiler because it will hold 
possible  particles  that  may  come  into  the  combi  parts 
from the radiators.
