02 · Did you know

Three things to know before choosing

01

One cabinet for four sizes

From 9,000 to 24,000 BTU/h, the cabinet keeps its 48.0 × 27.6 × 8.9 in. You pick the size for the room, not for the space.

TOSOT Bathica leaflet, “Floor-Ceiling” page.

02

11 lb more for the 24,000

The 9,000, 12,000 and 18,000 weigh 88.1 lb; the 24,000, 99.2 lb. On the ceiling, that is the weight being hung.

TOSOT Bathica leaflet, “Floor-Ceiling” page.

03

The 24,000 size on a 42,000

On the 42,000 BTU/h multi-zone compressors, the TOSOT brochure keeps the 24,000 head for cassettes, ducted units and floor-ceiling units, not wall units.
