AireTile Slim MLZ One-Way Cassette Air Conditioner/Heat Pump – Residential
Description

The Mitsubishi Electric AireTile Slim MLZ One-Way Cassette is a ceiling-mounted residential heat pump designed to deliver discreet heating and cooling. At just 185mm high and 360mm deep, it is New Zealand’s slimmest one-way cassette on the market. It fits easily between standard New Zealand joist spacing and into tight ceiling cavities where bulkier units can’t, making it the most practical and widely compatible choice for residential builds such as townhouses, apartments and modern architectural designs.

The single-room split-system includes the indoor ceiling cassette, matched outdoor unit, and a flush-mounted white grille that integrates with contemporary interiors.

Available in 3.2kW, 4.1kW and 6.0kW heating capacities, it provides a compact alternative where ducted systems are not viable and wall-mounted units are not desired.

AireTile Slim can also be connected as part of a Mitsubishi Electric OmniCore Multi Room Heat Pump System, allowing multiple indoor units to run from a single outdoor unit.

Key Features
  • Slim body design at only 185mm high, enabling installation in tight ceiling cavities.
  • Dual-level airflow selection to suit different ceiling heights (standard 2.4m or high 2.7m).
  • Auto vane control for left/right and up/down airflow adjustment.
  • Horizontal airflow mode helps minimise draughts by spreading air evenly across the ceiling.
  • Quiet operation with sound levels from 26 dBA — New Zealand’s quietest single-split one-way cassette on the market.*
  • Optional Wi-Fi Control for remote operation, scheduling, and efficiency optimisation.
  • Uses environmentally friendly R32 refrigerant with lower global warming potential.
  • Available in three capacity sizes: 2.5kW, 3.5kW, and 5.0kW cooling / 3.2kW, 4.1kW, and 6.0kW heating.

*In Heating Mode on lowest fan speed. 

 

Scope of Use
  • Designed for residential and light commercial applications including bedrooms, studies, hallways, and small offices.
  • Suitable for installation in low ceiling cavities (185mm depth) and between standard floor joist spacings of 450–600mm.
  • Dual-level airflow settings allow use in standard (2.4m) or high (2.7m) ceiling spaces.
  • All units supplied with wireless remote controller and flush-mounted grille.

Available capacities:

  • MLZ-KP25VG — 3.2kW Heating / 2.5kW Cooling (small rooms)

Limitations on Use

Indoor Unit should not be used/installed where: 

  • Airflow is blocked 
  • Where the unit is exposed to direct/reflective sunshine 
  • At a distance 1m or less from the TV or radio. Operation of the air conditioner may interfere with radio or TV reception 
  • Where the unit is close to fluorescent and incandescent lights so the infrared remote control can operate the air conditioner normally 
  • Where the ceiling is not strong enough to withstand the weight of the unit 
  • Where air filter is inaccessible 
  • Where the unit is close to another heat or steam source 

The Outdoor Unit should not be used/installed where: 

  • The unit is exposed to continuous direct sunlight or other sources of heat 
  • Where the unit can be covered by snow 
  • Where the unit is closer than 3m from a TV antenna or a radio antenna (Otherwise, images would be disturbed or noise would be generated.)
  • Where a rigid wall or support is not available to prevent the increase of operational sound or vibration.
  • Where neighbours are annoyed by operational sound or hot air.
Statement of Building Code Compliance

The full range of Mitsubishi Electric products have been tested and registered in accordance with MEPS (Minimum Energy Performance Standards) requirements.

It is also important to note that any heat pump outdoor unit installed without a compliant cover within 1.2m of a balcony rail will fall outside of these requirements. Mitsubishi Electric highly recommend Heat Pump Covers Ltd products in these situations, and have many examples of successful installations on multi-story apartment balcony spaces using Heat Pump Covers Ltd products.
