Installation precautions
• Choose the location of the appliance after discussion
with the client.
• The installation space should comply with current
regulations.
• To facilitate maintenance and allow access to the
various parts, we recommend that you provide
sufficient space all the way around the hydraulic unit.

• 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: "fluid fill 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 fill 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 flammable gas
near the heat pump during installation,
in particular when brazing is required.
The appliances are not fireproof 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).
-After each maintenance operation on the refrigeration
circuit and before the final connection, take care to
put the caps back in position to avoid any pollution
of the refrigeration circuit (sealing with adhesive is
prohibited).

Positioning the hydraulic unit
-Fix the bracket S securely (4 screws and plugs) to a
