Questions
Questions about ELIOS cassettes.
4-way or 1-way?
The 4-way blows in every direction from a ceiling square of 600 to 900 mm depending on size. The 1-way is long and narrow (430 × 1,300 mm opening) and only 335 mm deep: handy when space between joists is limited.
Is the grille included?
Not on the 4-way: ELIOS lists it as a “required grille”, sold separately (K0918AGRL for 9,000 to 18,000, Q2448AGRL for 24,000). The 1-way ships with its grille.
Where does the condensate go?
A built-in pump lifts it: up to 75 cm above the ceiling for the 4-way, 53 cm for the 1-way, per the ELIOS manuals. We plan the drain during the visit.
Is Wi-Fi included?
Yes on the R-454B cassettes: a wired wall controller with Wi-Fi is in the box, on top of the remote.
Why does the 9,000 have no LogisVert?
Hydro-Québec requires an outdoor unit of 12,000 BTU/h or more; the 9,000 is not on the Oct. 25, 2026 list.
What warranty?
ELIOS publishes 1 year on parts and 5 years on the compressor, with optional 10-year coverage. ELIOS publishes no labour warranty.
