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.

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.

18,000 BTU Stealth Comfort Designer Floor or Ceiling Mounted Single Zone Air Handler
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.
