This is a single-zone ductless mini split heat pump for cooling and heating one room without ductwork. It's built for homeowners adding comfort to a bedroom, addition, or garage that central air doesn't reach.
This Blizzard Series system pairs the outdoor condenser (model ABZCI4H4S09) with the matched indoor wall-mounted head (model ABZEM4H4S09) as an AHRI-certified combination — the two model numbers are not interchangeable with other capacity pairings in the Blizzard lineup. The wall-mounted indoor unit mounts on an interior wall (not a ceiling) and uses inverter-driven compressor technology for variable-speed comfort and dehumidification at low power draw. 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 unit: ABZCI4H4S09 (heat pump, inverter-driven, 208-230V)
- Indoor wall-mounted head: ABZEM4H4S09 (9,000 BTU/h, matched to outdoor unit above)
- Handheld remote control (included)
- 15' copper line set (included with this kit)
- 15' signal and power electrical cable (included with this kit)
Installation Requirements & Accessories
- Power supply: 208-230V — this system is NOT compatible with 115V-only circuits.
- Line set: 15' copper line set is included in this kit — no separate line set purchase is required for this configuration.
- Breaker size / circuit amperage: [NEEDS VERIFICATION] — confirm against nameplate data before installation.
- Not included: dedicated breaker/disconnect box, wall mounting bracket hardware beyond factory-supplied, and licensed installation labor.
- Not compatible with the ABZCI4H4S12 / ABZEM4H4S12 12,000 BTU outdoor/indoor pairing — those are separate matched units.
- Professional installation is required; this is not a pre-charged DIY quick-connect system.
Pro-Installer Tip
Flare connections on the 15' factory line set are a common leak point if torqued by feel instead of spec. Under-torquing (or over-torquing, which deforms the flare) allows slow refrigerant loss that shows up months later as reduced cooling capacity or an "E1" communication/protection code at the indoor head. Use a digital torque wrench matched to the flare nut size supplied with this kit, and always pull the line set down below 500 microns with a calibrated micron gauge before opening the service valves — a rushed vacuum is the single most common cause of comeback calls on inverter systems. This work falls under EPA Section 608 refrigerant handling requirements and must be performed by a certified technician.

FAQ
What breaker size do I need for this system?
Breaker size is [NEEDS VERIFICATION]. The system runs on a 208-230V power supply; confirm exact breaker/circuit amperage against the indoor unit ABZEM4H4S09 and outdoor unit ABZCI4H4S09 nameplate data 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 quick-connect kit. Professional installation by a licensed HVAC technician is required, including vacuum evacuation of the line set and refrigerant charge verification.
Is the line set included, and if not, what size do I need to buy?
Yes. This installation-ready kit includes a 15-foot copper line set along with 15 feet of signal and power electrical cable, the indoor wall-mounted head, the outdoor condenser, and a remote control.
Does this system work in cold climates (low-ambient heating)?
Yes. The Blizzard Series is rated for low-ambient operation down to 5° F for cooling and -4° F for heating.
Compliance & Warranty
Installation by a licensed HVAC professional is required to maintain warranty. Refrigerant handling, line set brazing/flaring, and evacuation must be performed by an EPA Section 608 certified technician. This unit is Energy Star qualified and carries an AHRI-certified indoor/outdoor matched performance rating. Full warranty terms are available under the "Resources (System Manuals and Warranty)" tab above.
