Fujitsu | Reverse Cycle Split System 3.5kW Cooling Lifestyle Range | R32 Refrigerant Wall Mounted
The Fujitsu ASTG12KMTC is a wall mounted reverse cycle split system air conditioner rated 3.5kW cooling and 3.7kW heating, charged with R32 refrigerant. The indoor head pairs with the AOTG12KMTC outdoor unit and is supplied as a matched indoor and outdoor set. The ASTG12KMTC runs on a 220-240V single phase 50Hz supply and sits in the Fujitsu Lifestyle range.
Small to medium rooms swing hard between summer humidity and cold winter mornings, and an undersized head labours at both extremes. The ASTG12KMTC addresses that with 3.5kW cooling and 3.7kW heating capacity, appropriate for bedrooms, studies and compact living areas. A rated EER of 3.93 and COP of 4.68 hold running costs down across extended cycles. Outdoor operation continues from -10 degrees Celsius in cooling and -15 degrees Celsius in heating, well outside typical Australian conditions.
Installers specify the Lifestyle range because the refrigeration pipework and the compliance paperwork both stay simple. The matched set carries 15 metres of precharged refrigerant against a 20 metre maximum pipe run, which covers most retrofits without extra charging on site. Fujitsu supports the equipment with a 5 year manufacturer warranty, and the set code is approved under the Victorian Energy Upgrades program. Specifying several heads across one house stays straightforward because mounting and controller operation remain consistent across the range.
Features
- 3.5kW cooling, 3.7kW heating — rated output modulates from 0.80kW to 4.10kW in cooling and 0.90kW to 6.10kW in heating, so the ASTG12KMTC trims back once the room settles.
- R32 refrigerant — carries a lower global warming potential than R410A while holding the same performance from the unit.
- EER 3.93, COP 4.68 — star rated 4.5 cooling and 3.5 heating in hot zones under the 2019 GEMS determination for units under 65kW.
- Human sensor control — the indoor unit switches to energy saving operation after 20 minutes with no movement detected, then reverts once someone returns.
- Super quiet mode — drops indoor sound pressure to 19 dBA in cooling and 21 dBA in heating, against 40 dBA and 42 dBA on high fan.
- Apple-Catechin filter — Sensitive Choice approved filter media absorbs fine dust and mould spores by static electricity, then inhibits further growth.
- Blue Fin heat exchanger — corrosion treatment on the AOTG12KMTC outdoor coil improves service life in coastal air.
- Demand response ready — the ASTG12KMTC switches to the matching operating mode when an electricity supplier activates a demand response signal.
- 20 metre pipe run — 15 metres comes precharged and maximum height difference between units is 15 metres, using 6.35mm liquid and 9.52mm gas connections.
- Weekly and program timers — separate on and off times can be set across seven days, alongside sleep timer, auto restart and auto-changeover.
- Up and down louvre only — the ASTG12KMTC has automatic vertical swing but no left and right or double swing action, unlike the larger Lifestyle models.
- 5 year manufacturer warranty — warranty runs from the invoice date and is void unless a licensed installer commissions the system.
Where to use
- Bedrooms — 19 dBA quiet mode on the ASTG12KMTC keeps night running well under the noise level of a standard ceiling fan.
- Home offices and studies — human sensor control winds the unit back when the room empties through the middle of the day.
- Small to medium living areas — 3.5kW suits open plan spaces of roughly 20 to 35 square metres, subject to insulation, glazing and orientation.
- Granny flats and studio units — a single ASTG12KMTC head handles both cooling and heating for a self contained space on one circuit.
- Rental turnovers and reno upgrades — the 20 metre pipe allowance suits retrofits where the outdoor unit lands well away from the head.
- Coastal properties — Blue Fin treatment on the outdoor heat exchanger stands up better to salt laden air than an untreated coil.
- Victorian Energy Upgrades jobs — SET-ASTG12KMTC is on the approved list for the VEU program in Victoria.
- Multi head house fitouts — several Lifestyle heads can be specified across a house with consistent mounting and a common controller layout.
The ASTG12KMTC is not sized for large open plan areas or whole of house duty, where a higher capacity head or a ducted system is the correct selection. Outdoor operation is limited to -10 degrees C in cooling and -15 degrees C in heating, so alpine sites need a check against local design temperatures. Installation, commissioning and any refrigerant handling must be carried out by a licensed and appropriately qualified professional.
