Air sealing oil

Give Ager Airconditioning a call in underwood - that is where I had that price - it was nearly two years ago now so it may have gone up

thanks for the info

Hey guys.
thanks for the info, gave me the confidence to install my 2 units this week, here's what i found.
Got my 2 at Kmart a month ago when they were on special for $299. Thay didn't come with the copper pipe (said so on box, saw some more at bunnings and was the same...??? go figure). Sourced some 1/4" and 3/8" paired pipe WITH insulation for $7.70 per metre! rented a pipe bender and flaring tool from hire place. mounted indoor unit on wall, drilled holes in wall, and bent pipes through to outside. ran drain and cables through. Ran to outdoor unit. i had one mounted on brackets up on the wall (second story), another on the ground.
Had a bit of difficulty flaring the pipes, not knowing how big to flare it etc...
Managed to find an aircon guy who i'd worded up a few days earlier, and he came out the same day i called! gotta be some kinda record. He vac'd both of them, had to redo my flares, and turned the gas on. only charged $120 for nearly 2 hours work.
After i finished the few little things remaining, plugged them in and turned them on. worked sensational!
So i recommend anyone to give them a go themselves. it's not too hard if you've done some diy stuff before.
all up INCLUDING units and parts, it cost me around $700.. not bad for something which would have cost me around $1700 if they'd done it all..:)

Hi Everyone, I bought one of the Mistral 1HP units from a local hardware and after reading a couple of informative threads about these units including this one decided to give installing it myself a go.
<O:p
Now everything went fairly well with the install and all the cables and pipes are connected properly as per the instructions but the unit won't heat. It seems to cool ok, it's a bit hard to try it properly as it's cold outside and in anyway but when it's turned on to heat the outside unit starts working but the inside unit doesn't do anything. After a while the inside unit coils develops a healthy covering of ice.<O:p</O:p
<O:p</O:p

No I've double checked the instructions, tested all the wire to make sure they're connected right but everything's seems ok. I was thinking I did something wrong with the air evacuation but then it should work at all?<O:p</O:p<O:p</O:p
<O:p</O:p

Does anyone know what the problem might be?

<O:p</O:p
Any help or advice (except the advice to call a professional) will be gratefully accepted.<O:p</O:p

Cheers Pedro :-)<O:p</O:p

I know this is stating the bleeding obvious, but have you made sure you have chosen the right settings. With our units, we crack the numbers up to about 27degrees celsius (I know that sounds way too high but it keeps the room a constant 20 degrees or so). The icon needed is the little thing like a sun, directly and just a few mm above the 2 of the 27. Works brilliant.

I'm just stating this because the instructions that came with our units were very confusing. I have heard they are better now.

Hi Arron, thanks for posting a reply, I'll give it another try but it does seem strange that the unit starts freezing the indoor coil in heat mode. My first thought was I've mixed up the wiring (the yellow and white wire are very similar in colour) so I tested but everything seems correct.

On the outside unit connections where there is an Allen Key underneath the capping nut how far do you have the Allen Keys unscrewed? My manual doesn't say much about this but a later vesion of the manual on the web says open both fully.

I think I'm going to have to call a Fridgie, I just hope I get a good one as my last couple of tradesmen haven't been the best.

Cheers Pedro :-)
