• In accordance with EN 378-1 -2017 standard
(Refrigerating systems and heat pumps - Safety and
environmental requirements), the system's hydraulic
unit and all refrigeration connections passing through
inhabited areas must comply with the minimum room
volume requirements shown hereafter.
The minimum volume of a room (in m
3
) is calculated
using the formula: "uid ll load" (in kg) / 0.39.
Alternatively, you must ensure that
- the location has natural ventilation through another
room where the combined volume of the two rooms is
greater than "liquid ll load" (in kg) / 0.39 kg/m³. The
opening between the two rooms must have a door
clearance of at least 1 cm.
- or that the location is mechanically ventilated.
• Be careful not to bring ammable gas near the heat pump
during installation, in particular when brazing is required.
The appliances are not reproof and should not
therefore be installed in an explosive environment.
- To avoid condensation inside the condenser, remove
the refrigeration circuit caps only when making the
refrigeration connections.
- If the refrigeration connection is only performed at the
end of the installation, make sure that the refrigeration
circuit caps* remain in place and tight throughout the
installation.
* (Hydraulic unit side and outdoor unit side).
gure 17 - Mounting bracket
- After each maintenance operation on the refrigeration
circuit and before the nal connection, take care to
put the caps back in position to avoid any pollution
of the refrigeration circuit (sealing with adhesive is
prohibited).
2.3.2 Positioning the hydraulic unit
- Fix the bracket S securely (4 screws and plugs) to a
strong, at wall (not a light partition) ensuring that it is
correctly levelled.
- Hook the appliance onto its bracket S.
