Page: 2 / 68

■ Installation and maintenance rules
The appliance must be installed and maintained by
an approved professional in accordance with the
prevailing regulations and code of practice.
■ Handling
The outdoor unit must not be in a horizontal position
during transport.
Transport in a horizontal position may damage the
appliance by moving the refrigerant and damaging
the compressor's suspensions.
Damage caused by transportation in a horizontal
position is not covered by the warranty.
If necessary, the outdoor unit may be tilted during
manual handling (to go through a door or use a
staircase). This operation must be conducted very
carefully and the appliance must be immediately
restored to the upright position.
■ Hydraulic connections
The connection must comply with good engineering
practices according to the regulations in force.
Reminder: Make the assembly seals according to
good engineering practices in force for plumbing
work:
- Use suitable seals or gaskets (fibre seals, O rings).
- Use Teflon or hemp tape.
-Use sealant (synthetic as required).
Use glycol water if the min starting temperature set
is lower than 10°C.
Use glycol water if the outdoor hydraulic links are
subject to a frost risk.
For the outdoor hydraulic links, use an insulator
which is suitable for outdoor use and is UV-resistant
(usage temperature -20 to +70 °C).
If glycol water is used, carry out an annual check of
the quality of the glycol. Use monopropylene glycol
only. The recommended concentration is 30%
minimum.
Never use monoethylene glycol.
• In certain installations, the presence of different
metals can cause corrosion problems; in this
case, the formation of metal particles and
sludge in the hydraulic circuit is seen.
• Use a corrosion inhibitor in the proportions
recommended by its manufacturer.
• It is also necessary to ensure that the treated
water does not become aggressive.
