ATTENTION!
Pipe/plumbing fittings do not constitute an element of the boiler’s original factory
fittings/equipment. The purchase of such devices and their connection to the boiler is
entirely the responsibility of the user.
Once the boiler is installed, it is necessary to:
−
Fill the entire heating circuit with water.
−
Carefully deaerate the entire central heating system and the boiler. This step will
need to be repeated a number of times during the first few days of operation of
the completed central heating system (it is recommended to supplement manual
deaeration with the introduction of fixed automatic deaerators into the system).
−
Precisely verify the leaktightness of the connection between the boiler and the
central heating system.
Do not install thermostatic valves on heaters located in the room in which the room
temperature regulator is to be installed, this because:
−
Temperature control is taken over entirely by the regulator which works together
with the central heating pump and boiler.
−
In the event of any change of the temperature set with the regulator, it would be
necessary to correct the settings of the thermostatic valves.
−
In the event of an inconsistency in this setting, the valves could close and cause
the boiler to function abnormally.
−
Thermostatic valves may be installed in all other rooms, and may be used to
regulate the temperature as required.
4.6. Guidelines concerning water quality
The quality of water used to fill the boiler and the system is of critical importance for
their longevity and trouble–free operation. Inappropriate boiler water parameters will result in
the deposition of boiler scale and may result in the production of corrosion foci, which may in
turn lead to equipment failures. The guarantee does not cover boiler damage due to
corrosion or the deposition of boiler scale. The water used to fill the boiler and the entire
heating system should satisfy the requirements set forward in pertinent standards and local
regulations.
The treatment technology applied to water intended for filling the boiler and the system
should allow attainment of the following parameters:
•
pH value > 8.5
•
Total hardness < 20°f
•
Free oxygen content < 0.05 mg/l
•
Chloride content < 60 mg/l
4.7. Connection to the electrical system
Bio-max Plus boilers can be powered from alternating current line 230 V/50 Hz fitted
with a protective conductor. The power lead and all ancillary devices (pumps, mixing valves,
room regulator, etc.) are to be connected through the terminal strip. The pertinent technical
details and locations of the corresponding terminals have been presented in the following
diagrams and described in the instruction manual and the documentation attached to the
controller. The power lead and ancillary devices are to be connected in accordance with the
markings on the terminal strip, paying particular attention to the order of the “L” and “N”
terminals.
