I have mine mounted on the right hand side of the trailer, with the ducting running along the rear of the trailer equally spaced along the facia at the top of the rear cupboards.

How did you route the ducting given you have put it on the left side of the trailer and the ducts exit towards the left side of the unit?

Cheers

Anthony

I'm actually selling my 2.4k Yamaha if anyone's interested,  I have only used it once when power went out to run my fridge. its listed on gumtree.
http://www.gumtree.com.au/s-ad/ferntree-gully/other-tools-diy/yamaha-2-4k-generator/1106020600

I'm down sizing to the 2k Yamaha in camo, I believe the 2k would run the aircon no problems, the 2.4k i'm selling will run it 100% and more.

Out of matter of interested does anyone have a 2.4k geni they carry on there 490?

Also how do these units go?  I read that they done heat below 4degrees which is no problem really as diesel heater will, and the cooling not below 20 degrees?
so how good are they?

a 2kva will run the aircon no problems - my eu20i has no issues.

We were in the Birindellas when the temp got down to -5 degrees outside, the temp inside was not much better. The reverse cycle didn't work (they do have internal protection that will turn them off it if tempreture is to low) but the Webasto made it warm and toasty.

We did use it in Melbourne when temp was around the 4 to 5 degrees outside and it coped OK, but we had it plugged into mains - it did cycle almost constantly though. I also used the aircon (ran nonstop on max heat and fan for 4 days) to dry the trailer out when we had major flooding whilst we were in Tasmania. Sydney saw temps around the 10 degree mark and the temp came up to a very comfortable no jumper and shorts.

Overall though, I do think it is easier to use the Webasto to heat as it is "cheaper" to run.

I have also used it in some pretty hot spots as well. It cools exceptionally well, especially if you have the fans to circulate the air around and push it up to the front of the bed. In Darwin, the boys put jumers on as it was pretty cold in the trailer.

Cooling to 20 degrees is more than adequate. Most Business places only cool to 24 degrees and most homes are set to about 22 degrees. 20 degrees is quite cool when it is 38 degrees outside.

Overall, I am very happy with the money I spent having it installed. This was one of the  things my wife wanted in a trailer, and I wouldnt place an order for my initial trailer until it could be airconditioned. Originally, the air cons were 12 volt - but they didn't cut the mustard, infact, they were useless. My trailer was the first to have the rear mounted model - and this is the one they have stuck with. I now have the same model in my new trailer.

Cheers

Anthony

I would say allow >$3000...the units outright price is $2000 plus fitting...you can get one with a remote and a digital thermo display

I would alllow a bit more for fitting - will not overly difficlt, it does require 240v circuit to be installed (which needs to be certified and inspected by your licensing authority - affects licence and insurance if not done). Also the cutting and sealing of the big hole in the back is quite tricky.

I wouldnt go for the flash one with a remote - something else that needs batteries and gets lost. All i did was lengthened the switch cable and ran it to the front of the trailer on the panel near the door.

Cheers

Anthony

Hello Doyta,
Like you have been interested in the aircon , tried to track down the Climaster model not available anywhere here in QLD, the Saphir looks like the only alternative
Very similar but as you say takes a little more power, but it's 8.5 kilos lighter!! So that would be a bonus for us trying to keep the weight down.
I don't know if the installation would be similar but worth finding out .too late for us for this trip as we leave on Sat .
Cheers Joe

Ok I did a bit of research an I believe the aircon is a Truma Climaster retro fitted pls see the link as an example

http://etime.com.au/appliances/air-conditioners/dometic-truma-climaster-underbunk-reverse-cycle-air-conditioner.html

We bought the van with it already fitted but it was done through CA / Opposite Lock WA.

They have made a retro shell / extra cowling to make it work.

The van was a the same time insulated.

You are correct, it is a Truma Climaster Comfort. The cowling is a custom job to cover what won't fit into the locker section The bulk of the Unit is on the outside of the trailer.

The Climaster is still showing on the Truma website and various supplier websites, but many are saying it is no longer available. It is my belief that it is no longer available - but it would pay to check with suppliers.

There are some differences between the Climaster and the Saphir (which replaces it). I have added a specification comparison in the link below.

The Saphir is slightly smaller in physical size, more cooling, less heating, less weight and more power draw. The biggest difference is really the way it gets its air supply. The Climaster is vented externally through the back (the bit that sits on the outside of the trailer) where the Saphir vents through the bottom of the unit (through the floor in a motor home). I have included a link to the installation manual (second link below) that shows the two vents required (page 10 onwards).

This will may present some issues for installation. If the exhaust vent is sufficiently far enough back, the vent could go through the bottom of the firewood rack. If not, it will need to be ducted somewhere to the outside of the trailer.

Given the Saphir is designed to sit in a storage compartment, it could be placed somewhere other than where it is "traditionally" placed on the UEV it may be able to be fitted in one of the side tool boxes and duct through the rear lockers (this is where I was going to place the first aircon I looked at fitting). It could also be placed in the lockers above the table and vent through the rear wall (behind the tyre). Depending on the unit (if it can be mounted in any position ie vertical/horizontal) it could also be placed into one of the Jerry can holder space and be boxed in with a stainless cowling. This is where the 12vunits were placed (these were ineffective though).

The above is just me brainstorming solutions - I have not seen anything other than a Climaster (and the crappy 12v systems) fitted. I hope it helps people understand what we are all talking about.

I have also inclded two photos of the units so you can all see the two units. The White unit is the Climaster, the black/grey one is the Saphir.

Cheers

Anthony

Anthony...thought....you could create a box like mine in the same position with a removable rear cover to suit the Saphir ...not hard.
So I'm in agreement with you to fit it as a rear mounted unit.
Who ever fitted mine did a professional job at it and I guess OL outsourced someone to do it.

If anyone requires closer pics of mine and measurements pls let me know.
