Enhanced Comfort
Stealth Designer Series Single Zone mini split systems provide the flexibility to use any of the available indoor unit types in a single zone application. Standard wall-mounted, flush mounted ceiling cassettes, floor-mounted and totally concealed ducted units are all available. You still get the precise temperature control, near-silent operation and maximum efficiency you expect from Stealth. There’s no more waiting to get exactly the system you want for your project.
OVERVIEW
The Stealth Designer Series Single Zone SC-18Z-UM heat pump condenser has a Gen 3 variable inverter compressor, for even, predictable cooling and heating without temperature swings or noisy on/off cycling. The condenser ships with a pre-charge of eco-friendly R410a refrigerant.
QUICK FACTS
18,000 BTU, 23 SEER
A system this size is suitable for rooms up to 750 square feet depending on climate in your area. The SEER rating of 23 means you pay less for this amount of heating and cooling compared to systems with lower SEER values. Stealth means elite performance and everyday prices.
14 Year Warranty
The Stealth Emerald Series features a 14 warranty with online registration. The standard warranty on the SC-18Z-UM is a 5-year parts and 7-year limited compressor warranty. With online registration and an installation following state and local installation codes, the compressor warranty increases to 14 years.
Durability and Reliability
Rugged construction, combined with an acrylic resin fin coating adds up to a long, trouble-free service life. Precision engineering is behind every Stealth Designer Series model, resulting in powerful performance across a punishing range of conditions. This SC-18Z-UM provides continuous heating down to an outside temperature of -31 degrees Fahrenheit.
Installation and Maintenance
Every Stealth Designer Series condenser includes a pre-charge of eco-friendly R410a refrigerant, enough for 25’ of line set per air handler. The line set fittings are compression-type and will require evacuation prior to refrigerant release. Line set kits- including both refrigerant lines, control wire and drain hose extensions, are available under Accessories on this page. Stealth Designer Series features self-diagnosing electronics. Should the system detect a fault, error codes will display on the front of the unit.
Please note:  
This system includes only the outdoor condenser, indoor air handler and wall mounted, or remote thermostat (depending on model) as depicted in the photo above. Additional Accessories are required to complete the installation. Each air handler requires a separate refrigerant line set, control wire and condensation control. The condenser requires connection to household power, wired through a disconnect switch and flexible, weatherproof conduit (whip). Additional optional accessories are also available. For help configuring your system, call (888) 377-2850
Stealth Designer Series Floor or Ceiling Mount Air Handlers can be surface mounted vertically or horizontally* for ultimate flexibility in placement.  The wider, flatter form factor makes it a good solution when you only have vertical wall space that is close to the floor, such as in an attic room.  Surface mount on the ceiling is also possible but may require a separate condensate pump to remove water. 
Please note: This air handler must be connected to an outdoor condenser in order to function.
