2.3 Installation of the hydraulic unit
2.3.1 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 to allow access to the
various components, we recommend that you provide
su󰀩cient space all around the hydraulic unit (gure 15).
• According to EN 378-1 standard (heat pumps: safety
and environmental requirements), the room where
the HP is to be installed shall have a minimum
volume of: machine charge in kg / 0.44kg/m
3
.
If not, it must be ensured that:
- Either the room is mechanically ventilated,
- Or the room's door remains open while the installer is
working on the HP.
• 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)
- 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).
