(2)
Branch piping should always be arranged to have level or perpendicular
branch.
(See the above fi gure.)
Notes (1) For model FDCVA802, always use ø12.7 mm liquid pipes, when the length of the main “L” exceeds 40 m. If ø9.52 mm pipes are used in an installation having over
40 m piping, they can cause performance degradation and/or water leaks from an indoor unit.
When the pipe length measures 60 m or longer for the model FDCVA802, we recommend the use of a ø12.7 mm liquid main.
(2) One-way pipe length should measure 5 m at a minimum. If the pipe length measures less than 5 m, then reduce the quantity of charged refrigerant. If you need to
recover or recharge refrigerant, contact our sales agent found in your neighborhood.
