Before Installation

The accessories needed for installation must be retained in your custody until the installation work
is completed. Do not discard them!
After carrying in the unit, protect it with packing materials to prevent it from scratching until installation work
is done.
[1] Decide upon a line of transport.
[2] Leave the unit inside its packaging while moving, until reaching the installation site. Where unpacking is
unavoidable, use a sling of soft material or protective plates together with a rope when lifting, to avoid
damage or scratches to the unit.
Hold the unit by the hanger brackets (4) when opening the crate and moving it, and do not lift it
holding on to any other part (especially the refrigerant piping, the drain piping, the water supply
piping, and the duct connecting flange).
