ACD · CCD ceiling cassette · 3 sizes
The ACD CCD cassette sits in a drop ceiling: only its square grille shows in the room. The 12,000 and 18,000 bodies are 231 mm tall, the 24,000 body 241 mm. A built-in pump lifts the condensate water. Enter the space you have: the “My drop ceiling” tool draws the cassette in your ceiling.

Nominal capacities, heights, grilles and weights: ACD multi-zone sheet (MPD-22). Pump and lift: CCD cassette manual (X62410), pp. 19 and 20. The margin only compares the body height with your space; at the on-site assessment we also check the structure, the drain, the refrigerant lines and the clearances.

Both hide in the ceiling and connect to the same MPD outdoor unit. Same nominal cooling, within 54 BTU/h; the rest differs.
Cassette · CCD18KCHVS-I
Ducted · SMD18KCHVS-I
Per the ACD multi-zone sheet, above the ceiling the 18,000 cassette needs 231 mm of height over 569 × 569 mm; the 18,000 ducted unit, 201 mm over 899 × 615 mm. The cassette lifts its own water (built-in pump, under 280 mm); the ducted unit’s manual keeps its drain lift under 850 mm. The ducted unit gives more heat (18,700 vs. 17,000 BTU/h).

Float
The CCD cassette manual describes a drain pump built into the cassette, with a float switch.
ACD CCD cassette manual (X62410), p. 19280 mm
Per the CCD manual, the cassette’s drain lift must stay under 280 mm (11 in.).
ACD CCD cassette manual (X62410), p. 20648 / 950
The 12,000 and 18,000 cassettes share a 648 mm square grille; the 24,000 takes a 950 mm grille.

The ACD cassette body is 231 mm tall in the 12,000 and 18,000 sizes, and 241 mm in the 24,000. That is the body alone; the installation clearances are checked on site. Below the ceiling, only the grille shows: 648 mm square and 48 mm thick, or 950 mm and 58 mm for the 24,000.
ACD multi-zone sheet (MPD-22), p. 3; ACD CCD cassette manual (X62410), p. 20The CCD cassette manual describes a built-in drain pump with a float switch. It lifts the water to the drain, with a lift under 280 mm (11 in.). The drain route is checked at the on-site assessment.
ACD CCD cassette manual (X62410), pp. 19 and 20The ACD cassette starts at 12,000 BTU: on the MPD 18,000, it only fits in the 09 + 12 pair. The 18,000 cassette, still on the 648 mm grille, needs at least an MPD 24,000; the 24,000, the only one with a 950 mm grille, an MPD 36,000 or 42,000 (the Multi-zone page compares them). In the ordering example of the MPD-22 sheet, the 18,000 cassette is the one that completes a five-head MPD 42,000.
Combinations printed in both ACD multi-zone sheetsThe ACD sheet prints 42 / 46 dB(A) for the 12,000 and 18,000 cassettes, and 35 / 39 dB(A) for the 24,000, even though it moves more air (500 to 694 cfm vs. 265 to 353). Both multi-zone sheets give the same values.
