Product details

Description

Overview

The Tosot Aoraki 18,000 BTU ceiling cassette mini split is a complete single-zone heat pump system: indoor unit, inverter outdoor unit, remote and installation package. It uses a high-efficiency inverter compressor, runs on 208/230V single-phase power and uses R32 refrigerant.

Ceiling cassettes sit flush in a drop ceiling and spread air in several directions, which suits open offices, retail space, restaurants and large living areas.

Key Features

  • Commercial-grade airflow: High-CFM indoor sections for large rooms, open plans, shops and offices.
  • DC inverter compressor: Smooth, efficient capacity control with R32 refrigerant.
  • Wi-Fi control: TOSOT+ app control and scheduling.
  • Built-in safety: Refrigerant leak detection and condensate overflow protection where equipped.
  • Wide operating range: Reliable cooling and heating across extreme outdoor temperatures.
  • Up to 21 SEER2 & 9 HSPF2 with R32 Refrigerant
  • ENERGY STAR Certified with tax rebate eligibility
  • 8-way airflow with 7-speed fan control for customized comfort
  • Built-in condensate pump with 47.2" lift
  • Operates in Extreme Temperatures from -40°F to 140°F

Performance & Efficiency

Capacity is matched to the room size listed below. The inverter compressor ramps up quickly to reach the setpoint, then slows down to hold it, which avoids the on/off cycling of single-speed equipment and cuts power use.

Comfort & Control

Every indoor unit includes a wireless remote, and the TOSOT+ app adds Wi-Fi control, scheduling and voice control through Alexa or Google Home. Sleep, quiet and turbo modes, auto restart after a power outage and a dehumidification (dry) mode are built in.

What's Included

  • Indoor unit
  • Outdoor unit
  • Wireless remote controller
  • 16 ft pre-flared copper line set, signal cable and power cord

Installation

Plan the indoor unit location, line set route, condensate drain and a dedicated electrical circuit before ordering.

Frequently Asked Questions
