Caution: the refrigerant connections must always be completed by
qualified personnel who have the qualifications and authorisations
required by local regulations, using appropriate personal protective
equipment (PPE), who are aware of the necessary precautions and who are
able to correctly and safely complete all required operations.
Residual risk of expulsion of pressurised fluids/bursting of equipment
if the instructions regarding the maximum pressure limits in the low
pressure circuit are not observed when checking for leaks with nitrogen
following welding on site.
Caution:
before charging the refrigerant circuit with nitrogen to
check for leaks or charging the refrigerant, check that the safety valve
outlet is correctly piped to an area where there are no residual safety risks
to people or objects.
Caution: the refrigerant circuit compartment closing panel is
connected to the rest of the structure by an earth wire (yellow/green). If
this wire is removed during installation, before closing the panel make sure
to connect it again, to ensure earth continuity between the panels.
4.5 Electrical connections
Caution:
the electrical panel closing panel is connected to the rest
of the structure by an earth wire (yellow/green). If this wire is removed
during installation, before closing the panel make sure to connect it again,
to ensure earth continuity between the panels.

4.9.1 Electrical panel inputs/outputs
Refer to the wiring diagram supplied with the Heos Box and the table
below for correct connection of the inputs and outputs to the Heos Box
electrical panel.
The mains power disconnect device must have a contact opening
distance that allows complete disconnection in overvoltage category III
conditions; it must also be incorporated into the HEOS BOX power supply
line in accordance with national regulations. It is compulsory to follow the
instructions on the wiring diagrams and comply with the minimum sizes
of the multi-core cables shown in the table below before connecting the
devices managed by the electrical panels.
