This is a single-zone ductless mini split heat pump for cooling and heating one larger room, open living area, or workshop without ductwork. It's built for homeowners who need higher-capacity comfort (30,000 or 36,000 BTU) in a single space that a smaller wall-mounted system can't cover.
The Tosot Starling series pairs a matched outdoor condenser and wall-mounted indoor head, rated by the manufacturer up to 22 SEER2 depending on capacity. Wall-mounted indoor units of this size are installed on an open wall section, not between ceiling joists, so joist spacing does not apply here. 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
- 30,000 BTU pairing: Outdoor condenser model TACCI7H4R30 with matched indoor wall-mounted unit model TACEM7H4R30.
- 36,000 BTU pairing: Outdoor condenser model TACCI7H4R36 with matched indoor wall-mounted unit model TACEM7H4R36.
- Indoor unit architecture: Wall Mounted, single indoor head per outdoor condenser (single-zone system).
Installation Requirements & Accessories
- Voltage: 208/230V, 60 Hz, single phase — this system is NOT compatible with 115V-only circuits.
- Line set size: 1/4" (liquid) & 5/8" (suction) for both the 30K and 36K variants.
- Line Set Sold Separately — not included with either variant.
- Wall sleeve and mounting bracket are not included; budget for these separately.
- Not a listed match for other Tosot Starling indoor/outdoor model families (e.g., ceiling cassette "EC" or concealed duct "EK" indoor units) — this configuration is a matched wall-mounted "EM" pairing only.
- Professional installation required; this is not a pre-charged DIY kit.
Pro-Installer Tip
Flare connections at the indoor and outdoor service valves are the most common source of long-term refrigerant loss on 208/230V systems like this one. A flare nut torqued by feel, rather than by spec, tends to loosen slightly as the copper cold-flows over the first few heating seasons, leading to slow leaks that show up as reduced capacity or an "E1"-style communication/pressure fault. Cut the flare square with an Eccentric Flaring Tool, inspect for surface scoring, and torque it to spec with a Digital Torque Wrench rather than an impact driver. Evacuate the line set below 500 microns and hold vacuum before opening the service valves — this is also the point at which EPA Section 608 certification requirements apply, since you're handling R32 refrigerant charge and recovery.
Key Benefits
- Variable-speed inverter-driven compressor for steady temperature control rather than on/off cycling.
- Rated for low-ambient heating down to -13°F, per manufacturer operating range.
- Higher-capacity single-zone coverage: choose 30,000 or 36,000 BTU depending on room size.
- SEER2 rating up to 22 (30K variant) for cooling season efficiency.
- R32 refrigerant.

- Outdoor condenser TACCI7H4R30 is matched exclusively to indoor wall unit TACEM7H4R30; outdoor condenser TACCI7H4R36 is matched exclusively to indoor wall unit TACEM7H4R36. Do not mix pairings across capacity classes.
- Not compatible with 115V-only circuits.
- Not a listed match for other Tosot Starling ceiling cassette (EC) or concealed duct (EK) indoor unit families — this listing covers wall-mounted (EM) indoor units only.
- Line set is NOT included with either variant — purchase 1/4" & 5/8" line set separately, sized to your installation run.
- Wall sleeve and mounting bracket are NOT included.
FAQ
What breaker size do I need for this system?
Breaker size is [NEEDS VERIFICATION]. The 30,000 BTU variant draws 11.8 amps and the 36,000 BTU variant draws 14.7 amps at 208/230V; confirm exact breaker sizing against the nameplate and local code before installation.
Is professional installation required to keep the warranty valid, or is this a true DIY kit?
This is a Non-DIY, flare-connection system. 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. Both the 30,000 BTU and 36,000 BTU variants use a 1/4-inch and 5/8-inch line set, purchased separately and sized to your run length.
Does this system work in cold climates (low-ambient heating)?
Yes. The manufacturer-rated operating ambient range is -4°F for cooling and -13°F for heating, on both variants.
