Questions about Fujitsu mini split evap

[lp13-30]

I have a chance to get a new 1.5 ton Fujitsu mini split evap at a very reasonable price. My plan is to add a txv to it and use a regular cond unit which I already have. I had done that with a made in Thailand POS that Goodman was selling. I just put a transformer and contactor in the storeroom next to the breaker box and wired the system just like a regular a/c, powering the contactor with the green circuit. It worked fine, but it was only a 1 ton and I really need a 1.5, and was also kinda dissapointed in the noise level of it. The Fujitsu is supposedly

230 volt, so I should be able to hook it up the same way. Anybody familiar with this unit and have an comments about it-- good, bad, average. No comments on my Frankenstein installation though :) Aaah WTF, any comments welcome. Larry

Why bother ripping the gut's out in order to put a tev? Keep it simple by using the existing exp device in the condenser and running the line sets as per spec but not forgetting to insulate the small line. This makes for a far cleaner installation and the outdoor works as it was designed too -i.e. with a pre-expansion line.

I can see the American market adopting the pre-expansion idea in the domestic market as it makes the install way easier and much quicker.It also deskills the install as the need for all those silly charging charts is gone when the condenser comes precharged for 30metres etc

I know for example that Daikin are looking very closely at this market and would expect something along these lines very soon.

We use these a/c condensers for cellar coolers where the outdoor needs to be very quiet -proper refrigeration ones are hellishly expensive- and we've found that with a fridge evap sized correctly remembering to derate the condenser for the lower temps they work really well.

Fujitsu are pretty good, Daikin and Mitsubishi are better but for your job it should be fine. I don't know if you get inverter ones there yet but these will not work in this set up so it needs to be the old fixed speed one.

Not familiar with the unit. Have fun, and let us know how things work out.

The only "unit" you are familiar with is the bosses.
