Important
Professional installation is recommended. This is an indoor unit intended to be paired with a compatible outdoor system. Confirm duct design/static pressure needs (ESP 0–0.8), electrical requirements (208–230V), line sizes (3/8" liquid, 5/8" gas), condensate routing (1" drain), and return/filter access before installation.
FAQs
What’s the key difference between high static and medium static slim ducts?
This model supports higher external static pressure (ESP 0–0.8), which helps maintain airflow in duct layouts with more resistance (longer runs, more fittings, or higher-effort registers) compared to medium-static units.
Does it support app control?
Yes. It includes a built-in Smart Kit for control via the C&H app.
What line sizes are required?
3/8" liquid and 5/8" gas.
Is it single-zone or multi-zone?
The indoor unit is listed as single-zone, and it can be used in multi-zone configurations when paired with a compatible outdoor unit.
Can it be installed horizontally or vertically?
The slim duct form factor supports flexible placement. Confirm clearances, condensate routing, and service access for your chosen orientation during installation planning.
