Fujitsu Lifestyle ASTG09KMCA (2.5kW / 3.2kW) Questions & Answers

look up the specifications on their website

its more powerful on heat being 3.2

Call customer service. Sounds like it needs a service

For the pipes, yes. And the bracket holds the unit up. Of course you need to get a professional to install it anyway so speak to them about where you'd like to put it etc.

The KUCA is part of the designer range and has a sleeker looking indoor unit

Units for Melbourne temperature is in degrees Celcius or degrees Centigrade (°C). No idea about Part b of your question - sorry! (What would that indicate? Why would you need that info? - just trying to understand the rationale there)

Thanks Vic. My reference to 'the units' should have been 'the unit's', that is the ASTG09KMCA. The seasonal coefficient of performance (SCOP) is an annual measure of the efficiency of the unit for a particular climate (i.e Melbourne for instance). Each local climate can have a different SCOP and each different reverse cycle unit with the same COP (coefficient of performance, which may be calculated for the most efficient temp for the unit, but not the average or range the equipment may encounter in the heat sink (i.e. the outside air temp and humidity) A reverse cycle unit has a different SCOP in each specific climate. In rating the reverse cycle units in the EU, they use two 'standard' climates, one where the average low is 2oC and one where is is -2oC, which may not cover all climates, but does give an idea for most climates in AU near sea level (90% of AU population). The calculation will give the annual total electricity the unit will use for a 'standard' installation, but does not vary on the particulars of the room/unit installed in, such as insulation, air leakage rates, and window area (i.e. heat loss/gain of the particular living space). With this SCOP information, one can calculate the total electricity used for the 'standard' living space to give an idea of how much electricity it would take to heat and/or cool their space and indicate what savings could be gained by installing the unit instead of using a electric heater or a gas heater. In my case I was only interested in the heating SCOP because I have a ground floor unit with morning sun and can get along with fans on hot summer days (last year their were no days over 40oC in Melbourne I believe). Also at some temperature the unit may not be efficient enough to use because it costs more to get one unit of heat out of the air, in which case one would want the unit to turn off and instead use a electric space heater or gas heater (depending on availability and relative prices). None of this information is available from the current consumer 'information' required to be included by the manufacturer to sell these units in AU, although it is required in the EU and I assume many other countries. For my space, I calculated I use an additional 2100KWH of electricity in the cooler months, which would mostly be heating (a bit more lighting and a bit less refrigeration electricity). To justify installing a unit for $2000, I would have to save more than 10,000KWH of electricity to cover the cost which would take more than six years if it had a SCOP of 5 (using 1/5 of the electricity of an electric heater, saving ~1600KWH/year at $0.20/kwh (off peak electric price currently about $0.128/kwh) and no imputed interest on the money sunk into installing and no servicing costs). If the reverse cycle unit has a SCOP of heating of 2 (even though it has a cop of 4.9) and imputed some lost interest on the money invested in installing the unit, and some maintenance, it may take 15-20 years to pay for itself, way beyond the 5 year guarantee of the unit, therefore not be worth the effort.

I too have just purchased two myself, you have to remember that very few happy people leave reviews. Reviews are usually swayed by people who are upset and need to vent (nothing wrong with this). I have had a few Fujitsu units (ducted and split) in the past and never an issue.... not one.... However I have no experience with this model and will leave a review after it is installed.

Remember to do your research on the installer and don't go with the cheapest. The best system installed poorly will function worse than a cheap system installed correctly.
"It's not the machine that heats and cools your home, its the person who installs it"

Yes, you can but you will have to get zoning (isolating) solenoids installed in each room so as to zone them, unless you want to cool down the rooms together, which is not very economical.
The size of the outdoor unit (Keating/cooling capacity in Kw) depends on the size of each room.
The Unit you have mentioned will suffice probably only one room.

the answer here is incorrect. you cannot connect two indoor units to one outdoor unit unless it is a multi head type outdoor unit designed for this. these cost more than two separate units and are only used where space for outdoor units is limited, such as on the balcony of a unit.

I have had a multi head air conditioner and in the long term I would not recommend it. When it worked it was great but now that it has died during a heatwave, I have no air conditioning at all in any of the bedrooms. If you have separate units you dont lose everything. It actually worked out cheaper for me to buy 3 separate units rather than replace the original triple header.

NO NO NO - It depends what your room temp is at that moment.
Please renew the batteries in the hand held remote to a good quality Lithium type ASAP. Re-enter the time & day info. Switch on the air con with the remote & ensure it is set to Auto Mode, Auto Fan, Low Outdoor Unit Noise & Economy Mode. Only adjust the set temp range up or down as required. If necessary on a very hot day, set the temp to 18 deg C on start up & then after 10 mins switch back to Auto Mode for desired temp. Similar set to 30 deg C on a very cold day & then after 10 mins switch back to Auto Mode for desired temp. Using Auto Mode for the outdoor compressor unit will modulate the speed / power of the compressor as it nears the set temp. thereby saving money. Similarly using Auto Mode for the indoor head unit fan will modulate the fan speed / power as it nears the set temp. thereby saving money. This is how I operate all my 4 air con units. Bravo Fujitsu, keep it up.

All very confusing.
Why not be able to have "Cool Mode" or "Heat" - "Low Fan" - "Economy mode" and set the fan speed to whatever
instead of all the fiddle.
I have an 8-year-old Chinese model in the lounge and that's all I do with that though it doesn't have the economy mode
and if I turn it down to 18c I think it would throw ice blocks at me.
Not impressed.

The answer that begins with "NO NO NO" has some good info but may not help get your room to temp quickly.
Auto fan is good, however auto "mode" can occasionally swing from heat to cool, Weather set to heat, cool or dry, the system will only run at the speed required. Select your mode and the temp want and then press the "powerful" button, It will basically put the unit into overdrive and ignore the set temp for about 30 minutes, after this it will revert to the previous settings.
Settings such as economy or "low noise" limit the outdoor units operational capacity to about 70%, good when your comfortable, not the best when you need the extra capacity.
