3.3.2 Preparation and connection of the remote installed spa pack (option)

A) Selecting the installation site and running the lines
The spa pack may be installed at a distance of up to 7.5 m from the spa.
The spa pack must not be installed at a height lower than 1.5 m below the water level. It must however be
installed at a height below the water line.
The installation site should be:
• Well- ventilated,
• Sheltered against the elements,
• Protected against dust,
• Not subject to streaming or the accumulation of rain water,
• Allows the pipes and tubing between the spa pack and mounting plate to be run straight (no bends).
The pipes and tubing run between the spa pack and spa pack mounting plate should be protected against
trampling, impact, direct exposure to UV light and should not be in contact with sharp objects (sharp
stones, etc.).
They may be cut to length.
The path should be as direct as possible to facilitate the circulation of water between the spa pack and the
spa.
