Hydraulic Connection - LAMINOX Idro TERMOBOILER Mini Series Instructions For Installation, Use And Maintenance Manual

5.4

Hydraulic connection

Connection of the boiler to the hydraulic system must be exclusively performed by qualified
personnel, who is able to perfectly perform the installation, complying with the regulations
in force in the Country of installation.
If the installation of the boiler requires interaction with another pre-existing system equipped with
another heating device (gas boiler, methane boiler, gasoline boiler, etc.), contacting qualified
personnel able to respond to the conformity of the system, according to the requirements of the law
in force regarding the subject, is more recommended.
The company denies any liability in case of damages to property or persons or in case of no
or incorrect operation if the aforementioned warnings are not complied with.
Caution: To connect the delivery pipe, return pipe, refilling pipe and drains arrange flexible hoses
at least 70 cm long and shut-off shutters in order to isolate the machine from the water system
should moving it to perform routine/special maintenance be required.
Connect the thermal safety drain of the machine to an appropriate drain funnel with no shut-off
valves.
In case of thermal safety drain valve operation, the water must be free to flow without causing
damage to persons and built-up area.
When the instrument is fully operational it produces hot water at a temperature necessarily lower
than the boiling one and therefore the thermal system must be designed in compatibility with the
machine specifications.
During installation and operation take into account that disposal of the minimum power delivered by
the machine must be ensured.
Make sure that the thermal hydraulic system is fitted with an additional and adequate closed
appropriately dimensioned expansion vessel.
For the installation of an additional expansion vessel take into account that usually 1 litre of vase
compensated 10 litres of system and at least 1 litre is always dedicated to the water inside the
boiler. The expansion vessel inserted inside the device is pre-charge at the pressure indicated in
the plate, adjust the pre-charged pressure of the expansion vessels to the operating pressure of
the thermal system.
We recommend installing a 1" anti-condensation valve with 55 °C opening and softener
systems.
It is best to keep in mind that deposit drastically lower performance due to their extremely low
thermal conductivity.
5.4.1 System filling
Before performing the boiler connections thoroughly wash the thermal system (pipes,
heating bodies, etc.) with appropriate paint or deposit removers able to remove any residues which
may compromise the correct operation of the boiler.
Hydraulic connections must be performed rationally using the connections of the boiler. The boiler
safety valve drain must be connected to a drain funnel. Otherwise, if the drain valve operates
flooding the room, the boiler manufacturer shall not be deemed responsible.
We recommend filling the system at a pressure of 1.0 - 1.2 bar (pressure is shown with the b
symbol on the boiler display) the boiler can still function from 0.6 bar to 2.5 bar.
In case of installation in spaces where temperature may drop below 0°C, inserting appropriate
.
antifreeze in the system is required since the boiler does not have an automatic antifreeze system
