This is a single-zone ductless mini split system for cooling and heating one room without ductwork. It's built for homeowners adding comfort to a bedroom, addition, or office that central air doesn't reach.
The Air-Con Titanium 9000 BTU system pairs a wall-mounted indoor head with a matched outdoor condenser, AHRI-certified as a set for reliable rated performance. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
System Components
- Outdoor Condenser: ATUCI4H1S09 (9,000 BTU, 19 SEER, 208-230V)
- Indoor Unit: ATUEM4H1S09 — wall-mounted air handler
Installation Requirements & Accessories
- Voltage: 208-230V — confirm your electrical circuit matches before ordering. Not compatible with 115V-only circuits.
- Line set size and length: [NEEDS VERIFICATION] — not provided in manufacturer data supplied for this listing.
- Line Set Sold Separately — this system does not ship with a pre-charged line set.
- Not a listed match for indoor/outdoor combinations outside the ATUCI4H1S09 / ATUEM4H1S09 AHRI-certified pair.
- Wall mounting bracket for the indoor head — confirm inclusion against the manufacturer's packing list in the Resources tab; not confirmed in data supplied here.
Pro-Installer Tip
Flare connections on 9K systems are a common source of slow refrigerant leaks if torqued by feel rather than spec. Under-torquing leaves a gap that bleeds refrigerant charge over months, eventually triggering low-charge fault codes and robbing the system of rated capacity. Use a digital torque wrench set to the flare nut manufacturer's specified value, not a generic "snug plus a quarter turn." Confirm the line set has been evacuated below 500 microns with a calibrated micron gauge before opening service valves — this is standard EPA Section 608 practice and directly protects the system's rated 19 SEER efficiency.
Key Benefits
- Inverter-driven compressor for variable-speed comfort rather than blunt on/off cycling
- Wall-mounted indoor head suited to bedrooms, additions, and offices without existing ductwork
- Rated 19 SEER efficiency on the 9,000 BTU pairing
- AHRI-certified matched indoor/outdoor combination for verified rated performance

FAQ
What breaker size do I need for this system?
Breaker size is [NEEDS VERIFICATION]. The system operates on 208-230V; confirm exact breaker and wire gauge requirements against the installation manual under the Resources tab before rough-in.
Is professional installation required to keep the warranty valid, or is this a true DIY kit?
This is a standard flare-connection system, not a pre-charged DIY kit. Installation by a licensed HVAC professional is required to maintain the warranty.
Is the line set included, and if not, what size do I need to buy?
The line set is not included. Exact line set size (diameter and length) is [NEEDS VERIFICATION] — confirm against the installation manual for the ATUCI4H1S09 / ATUEM4H1S09 pairing before purchasing.
Does this system work in cold climates (low-ambient heating)?
Low-ambient heating performance data is [NEEDS VERIFICATION] for this model. Refer to the manufacturer's Product Specifications for confirmed operating temperature ranges.
Compliance & Warranty
Installation by a licensed HVAC professional is required to maintain warranty. Refrigerant handling and line set evacuation must be performed by an EPA Section 608-certified technician. Full warranty terms are detailed in the manufacturer's documentation — see the "Resources (System Manuals and Warranty)" Tab above for complete coverage terms.
