COMMISSIONING OF THE BOILER
3.1
Prior warnings
Repair and maintenance of the boiler must be carried out by a qualified professional, authorised by
DOMUSA TEKNIK
. For optimum functioning and conservation of the boiler, it should be serviced
annually.
Carefully read this instruction manual and keep it in a safe, easily-accessible place.
DOMUSA TEKNIK
will not be liable for any damages caused by failure to follow these instructions.
Before any servicing, disconnect the boiler from the mains.
3.2
Filling the installation
The hydraulic installation must include a disconnector key, drain valves and the necessary hydraulic
components for correctly filling the installation.
Before filling the primary circuit, make sure that
the secondary (DHW circuit) is full.
To fill the installation, open the fill valve until the parameter
“Water pressure”
of
“User Menu”
shows a
pressure of 1 - 1.5 bars. The installation must be filled slowly, bleeding the air from the water circuit
using the drain valves provided on the same. Close the fill valve after filling.
Bioclass iC DX
boilers have a pressure sensor for controlling the pressure of the installation. If the
installation does not have the minimum pressure set at
P.19
parameter of
”Technical Menu”
(by default
0.5 bar), a low pressure alarm will appear ("
E-19
").
IMPORTANT: Switching on the boiler with no water inside could result in serious damage.
3.3
Initial calibration of the feed auger
Bioclass iC DX
boiler is equipped with a feed auger to supply the fuel. Follow the instructions described
in
"Installing the hopper”
section
to install it correctly. Due to diversity of feed augers and the range of
different hoppers, it is needed to calibrate the feed auger minimum twice to assure the correct running.
Follow the instructions described in “
Feed auger calibration”
section of
“Setup menu”
to assure a correct
calibration.
