The specifications shown in the above table are for units without heaters. For units with heaters, refer
○
to the installation instructions or the construction instructions of the indoor unit.
Switchgear of Circuit breaker capacity which is calculated from MAX. over current should be chosen
○
along the regulations in each country.
The cable specifications are based on the assumption that a metal or plastic conduit is used with no
○
more than three cables contained in a conduit and a voltage drop is 2%. For an installation falling
outside of these conditions, please follow the internal cabling regulations. Adapt it to the regulation
in effect in each country.
