Storage
SPI units should be stored in a clean and dry environment. They should be protected against condensation
inside the packaging. Direct contact with wet timber pallets and packing cases should be avoided. Storage
temperature should be between 0°C and 40°C (32°F and 104°F).
SPI design life is 40 years from manufacture date, inclusive of storage duration.
