*2 90m [295ft] is available. When the piping length exceeds 40m [131ft], use one size larger liquid pipe starting with the section of piping where 40m [131ft] is exceeded and all
piping after that point.

A water energy source system that allows switching
between cooling and heating
The CITY MULTI WY-Series provides all the benefits of the Y-Series using water-cooled heat source units.
Heat source units can be situated indoors for greater design flexibility with no limitations on building size. Depending on
capacity, up to 50 indoor units can be connected to a single heat source unit with individualized and/or centralized
control. The two-pipe system allows all CITY MULTI units to switch between cooling and heating while maintaining a
constant indoor temperature.
