Daikin FTXD35AV1H 1.5 HP 420 R32 Inverter Heat Pump Wall-mounted Split Air Conditioner

The Daikin FTXD35AV1H is a 1.5 HP R32 inverter heat pump wall-mounted split air conditioner in the 420 series, combining cooling and heating in one unit. Its outdoor unit is 420mm high and can be installed in the position of an existing window unit, suiting households that want to regulate room temperature all year round with a single unit.

Cooling 11,000 BTU/h, heating 14,400 BTU/h, Grade 1 energy label for both cooling and heating

Cooling capacity is 3.22kW and heating capacity is 4.22kW. CSPF is 5.0194 and HSPF is 4.3277; annual cooling energy consumption is 324kWh and heating energy consumption is 42kWh. Inverter technology controls the compressor speed to keep the room at the set temperature, without the repeated starting and stopping of a fixed-speed unit, which reduces energy consumption.

It has auto cooling/heating changeover; when heating with the heat pump, it takes about 3 minutes to warm up after switching on before warm air is delivered. When choosing the horsepower, consider not only the room size but also the number of occupants, sunlight and insulation; west-facing rooms, top-floor rooms and rooms often used by several people may need a higher cooling capacity.

Streamer discharge and Gin-ION silver-ion filter

In the 420 series, only the FTXD cooling and heating models have Streamer discharge, which releases high-speed electrons during discharge to oxidise and break down harmful chemicals, thereby killing bacteria and eliminating odours. The Gin-ION silver-ion filter works mainly on the filter surface: it breaks down and deactivates viruses attached to the filter, destroys the cell membranes of bacteria, and filters dust, pollen and allergens.

420 series outdoor unit, suited to narrow window ledges

The outdoor unit is 765mm wide and 291mm deep and weighs 24kg; it can be installed on the existing window unit platform. The pipe and cable connection point is at the back of the outdoor unit and can be reached from indoors, simplifying the work and reducing the space required; scaffolding may not be needed during installation, depending on actual circumstances and the building structure.

3D all-round airflow and smartphone control with Daikin Mobile Controller

It swings automatically up and down and left and right, and together with the power-airflow flap and extra-wide airflow angle distributes air evenly to every corner of the room. Maximum airflow is 10.19m³/min for both cooling and heating, and the indoor unit noise level is 31-41dB(A).

Daikin Mobile Controller is standard. With an internet connection and wireless LAN coverage at home, you can use your phone to switch the unit on and off, set the mode and temperature, schedule a weekly timetable and monitor the air conditioner remotely. An ARC485B2 remote control with luminous buttons is also included.

Comparing horsepower options in the same series

The FTXD25AV1H is 1 HP, with cooling of 8,800 BTU/h and heating of 11,000 BTU/h; its outdoor unit is 695mm wide and 418mm high, shorter and narrower than this model. The FTXD50AV1H is 2 HP, with cooling of 17,100 BTU/h and heating of 15,400 BTU/h, and an indoor unit 990mm wide. If you only need cooling, consider the cooling-only model FTKD35AV1H, also 1.5 HP.

Before you buy

• The indoor unit measures 770 x 288 x 234mm (W x H x D) and weighs 9.5kg.
• Maximum piping length is 20m and maximum height difference is 10m.
• When defrosting during heating, the frost on the outdoor unit melts into water; when cooling or dehumidifying, moisture in the air also condenses into water on the refrigerant pipes of the outdoor unit.
• R32 is a mildly flammable refrigerant. It must be installed and serviced by technicians with relevant experience, who must confirm the indoor unit installation height and the minimum room area.
• Warranty: the indoor unit and outdoor unit must be purchased together. Register online with Daikin within 1 month of purchase to receive a 2-year full unit warranty and 5-year compressor warranty; without registration the warranty is 12 months.
• Other horsepower options in the same series: FTXD25AV1H (1 HP), FTXD50AV1H (2 HP).
