▼ 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
suffi cient space all the way around the hydraulic unit
(fi g. 19).
• Fix the hydraulic module to the ground
(fi xing system not supplied).
Other cautions
Be careful not to bring fl ammable gas
near the heat pump during installation,
in particular when brazing is required.
The appliances are not fi reproof and should
not therefore be installed in an explosive
environment.
To prevent risks of humidity in the exchanger,
it is pressurized with nitrogen.
- 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 fi nal connection, take care to
put the caps back in position to avoid any pollution
of the refrigeration circuit (sealing with adhesive is
prohibited).
