Split System Air Conditioner

[Lord-Data]

Does anyone know if these are installable without a lisenced installer? From
my understanding, they are a standard powerpoint plug? Can anyone confirm
this?

In particular, this is a 1HP Mistral split system .. Is it something that
just wired into power and has a pipe put thru the wall to the outside unit?

Thanks in advance!

**Are all the lines charged? If they're not, you'll need to pay someone to
evacuate the system and charge it. Wiring it up is child's play. Of course,
you SHOULD employ a professional for this too.

The split system I had installed was gassed on site after all the

plumbing was put in. The power was the easy bit. I believe there's an
expansion valve in the wall unit and a compressor and heat exchanger
outside.

No licence required to install a domestic a/c -- unless the police
states have different rules. Wiring changes will need a licenced
electrician, who isn't likely to be the best person to commission it.
There's no reason why you can't run a small unit from a 10A GPO (check
its starting current from the spec sheet).

Ours (Daikin) came with the refrigerant charge (R22) pre-installed in
the compressor unit -- which is pretty much standard AFAIK. After
connecting the pipes it's necessary to evacuate the wall unit and
pipes and leak test before opening the valves on the outside unit. I
did my own using automotive a/c equipment (no licence required for
that either) -- electrician wired it as it's a largish unit (3kW
IIRC).

Be particulary wary of installers who don't use a vacuum pump (heaps
don't). The cheapskate trick is to use some of the refrigerant in the
compressor to flush the evaporator. Not only will you finish up with
a reduced charge containing air and moisture -- you'll also void the
manufacturer's warranty. FWIW the electrician who wired ours thought
that was the correct way as it was the only way he'd previously seen
it done.

Assuming you want to know the legal side of it:
Needs fixed wiring complying with AS/NZ 3000 so rules say must use an
electrician (all states).

Flaring of lines required for refrigerant, also have to open valves to
release
R22, so by law supposed to have someone accredited to use refrigerants.

Having said that, everyone thinks they can do it anyhow, just like fixing
your own car!.

BTW, the Mistral units are about as good as LG!
Cheers.

I've managed to find and download the install manual in PDF, it really seems
to be aimed at someone who plans to DIY .. The manual just mentioned
"discharging the air within the unit" as:
Remove screw cap closing valve gas chagring hole
Open closing valve with allen key, and push in the gas charging hole for
about 10 seconds, until a gas like fog appears
screw down the screw cap charge hole
check for leaks

No mention of vacing anything

Mentions that you only need to add refidgerent if your hoses are longer than
7m.

Having said that, everyone thinks they can do it anyhow, just like fixing
your own car!.

BTW, the Mistral units are about as good as LG!

Is that a good or bad thing?

It is for a very small room that can be closed off, so even if its a lower
spec/quality unit, it should do me fine, and its a damn good price at the
moment (Kmart)

Cheers.

and the hoses are optional extra, good luck trying to buy any.

As someone else mentioned the lines 'should' be pulled down with a vac pump
to ensure all air is removed.

The method outlined above sounds like "purging", works but not the correct
way to do the job. ( have to wonder what the EPA would say about HFC's being
released into the atmosphere!)

Mentions that you only need to add refidgerent if your hoses are longer
than
7m.

Hoses will turn out to be annealed copper tubing, liquid line probably 1/4

inch
gas line either 3/8 or 1/2". You get to make your own flares on the pipes
as well.

Just a smart alek comment
LG doesn't have the best reputation..

spec/quality unit, it should do me fine, and its a damn good price at the
moment (Kmart)

Should be fine, I didn't mean to insinuate it was a POS per se, just that
its not the best brand available. Having said that Mistral have good
warranty and won't be gone tomorrow if it does develop a fault.

Cheers.

If you have to handle refrigerant (which you will either
purging/vacuuming/charging your system)
http://www.findlaw.com.au/Legislation/legislationhtml.asp?id=43491
Any fixed wiring has to done by a licensed electrical contractor.

All that aside, there are few things to be aware of when installing splits:

1. make sure the service valves (gas and liquid lines) are opened fully on
commissioning
2. take particular care when installing the drain, as this pipe is under a
slight vacuum
from the head blower, any slight elevation will cause the pipe to block
backing
up condensate to leak from the head.
3.never pull on the liquid/gas line at the head as they facture easily
4.it is easiest to install the head on a wall that is common with the
building exterior for the purpose of the drain.
5.allow the condensate to drain into a tundish before connecting to a sewer

Best of luck

ROFLMA

He could always move to Queensland which has no licensing requirement
(as well as a lack of federal agents engaged in the detection such
offences).

Or else move to R290, which isn't a CFC, HCFC, HFC, PFC or halon, and
isn't therefore covered by the above legislation, and will no doubt
become a popular alternative in the police states after July 1. It's
performance is similar, if not superior to R22 (which is currently
being phased out for a vastly inferior alternative).

R290 is not only endorsed by Greenpeace, it's also so widely available
that most households already have at least one 9kg container on hand.

Yeah, should make leak testing a lot easier too, if you smoke that is ;o)

Seems to have gone the complete loop, NH3 and R290 were the primary
refrigerants
used before Freon..... I think the motivation away from ammonia, propane,and
petrol ether was an
obvious one then, I wonder why not now?
