3-2. Installation precautions

• Choose the location of the appliance after discussion with the client.
• The installation space should comply with the 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.
• Fix the hydraulic module to the ground.
• 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 prevent risks of humidity in the exchanger, it is pressurized with nitrogen.
• To avoid condensation inside the condenser, remove the refrigerant circuit caps only when making
the refrigeration connections.
• If the refrigerant connection is only performed at the end of the installation, make sure that the re-
frigeration circuit caps (hydraulic unit side and outdoor unit side) remain in place and tight through-
out the installation.
• 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.)
