BIO hydraulic kit installation
In option a
BIO hydraulic kit
, within the kits range offered by
DOMUSA TEKNIK
, could be connected
to
Bioclass iC DX
boiler. In that way the features of the boiler will be increased.
Look at the following instructions for a correct installation:
•
Unplug the boiler and the hydraulic kit from the main power supply.
•
Connect the communication between the boiler and the hydraulic kit, connecting the
J4
electrical strips of both devices (see "Connection Diagrams"), for which, you must use a 2-
wire electrical hose and the 2-way strip
(+ A / -B)
supplied together with the Kit (in the
documentation bag).
To assure the correct running of BIO hydraulic Kit it is essential
to respect the polarity of the connection. The same wire must be connected to the
+A terminal of the boiler as well as to the +A terminal of the hydraulic Kit. Same
operation with the –B terminals.
•
After connecting the communication between the boiler and the hydraulic Kit, plug the
BIO
hydraulic Kit
to the main power supply. It is recommended to plug the Kit before the boiler
to assure a correct running of the system.
•
Plug the boiler to the main power supply.
Follow the instructions provided with the kit to assure a correct installation.
IMPORTANT: It is compulsory to respect the polarity of both wires of the cable to assure
a correct running of BIO hydraulic Kit.
NOTE: In order to have a correct communication between the boiler and the BIO Hydraulic
Kit, it is necessary to connect first the Kit to the mains and then the boiler.
2.9
Loss of pressure in the boiler
To correctly size the hydraulic installation and choose the correct pump operation and pump operation
curves, the pressure loss caused by the boiler should be taken into account. The following graph
describes the pressure loss curves according to the model of
Bioclass iC DX
boiler:
