Service engineer with authorization from the manufacturer is obliged to make a verifiable
demonstration for the user of the boiler operation, its individual parts, safety components and control
methods prior to putting the boiler into operation and fill in the letter of guarantee and hand over this
Operation and Maintenance Manual to the user.
User is bound to observe the correct use of the boiler in accordance with this Manual; this is a basic
precondition for acknowledgement of the warranty. It is further strictly forbidden to interfere with any of the
sealed parts inside the boiler!
Warning:
The settings of the boiler output range and other parameters must be in compliance with the technical data.
Any excess loads or incorrect use of the boiler can cause damage to its components. Warranty does not apply to the
components which suffer this kind of damage!
♦ General instructions:
The following must be checked before the electric boiler is set into operation:
▪connection to the heating system
▪opening of the fittings separating the electric boiler from the system and securing them against
manipulation
▪charging (may be followed by pressurizing) the system by soft water and subsequent bleeding
▪electric connection and protection in line with the CSN standards. For further details refer to the Chapter
“Wall-mounting of the boiler”.
The procedure for setting the boiler into operation is as follows:
▪switch on the main circuit breaker (switch) in the power intake, switch on the boiler by pressing the O/I
button for heating actuation
▪set the desired outlet boiler temperature to maximum
▪check the correct functioning of all safety thermostats and control components
▪check the settings of the boiler output range, potentially adjust the settings on the basis of the heated
building.
Electric boiler operation is very simple and fast and does not require any special qualification. The boiler can be
nevertheless controlled only by adults who have been demonstrably explained the boiler function and
operation. This demonstration must be performed by the worker who carried out the installation and set the boiler
into operation.
▪If the display is turned on, the control supply voltage is fed to the boiler.
▪Set the room thermostat (or other control element) to the required temperature.
▪Display the current heating water temperature by pressing the Arrow Up button. To switch on the boiler
press the O/I button in the heating temperature setting section. Concurrently, the circular pump is switched
on which runs for the period defined by the set parameters. The heating function is indicated by the LED
pilot light in the left section of the control panel = “HEATING”.
▪After the set temperature has been reached, the automatic controlling system gradually switches off the
heating bodies in order to maintain the heating water temperature within the range specified by the
parameters.
▪First heating: maintain the highest possible service temperature of the heating medium in the system for the
first four hours. The system must be carefully deaereated while in operation to rid it reliably off the
remaining air after the previous bleeding in the cold state. When the system cools down, refill it with water.
