HI Neil
[1]Both pics seem to indicate quite a large space each side & o top of the FRIDGE
ALL BAD place for hot air to accumulate & massive cooling air loss by passing the condenser ,even withe a fan on the grills
Solution
ON top,
force some styrofoam sheeting into the top gap to completely fill it if you can THAT will also ADD extra insulation
ON the sides,
the picture is a bit decieiving as it appears The cabinet inclosure sides are angled but I suspect they are parallel to the fridge sides??
Again pack as much Styrofoam sheeting as you can in that space,making sure that they are in contact with the FRIDGE sides
IF it as wide as I suspect THAT will realy add some insulation& reduce losses
ITdoes appear that the fridge rear is pretty close to the van side wall can you measure THAT clearance at the closest point??
The
actual location of the top vent does not look too bad
If there is an air gap between the chip board & theTOP section of the vent grill vent, it would not be a probem , IF you fit fans at the bottom of the condensor
I cannot see the actual boiler, exhaust flu etc?
Does it have a direct connect to the outside via the top grill
Please post
pic if you can of that section LOOKING DOWN INTO IT& the top grill itself
IT may be advisable to fir some horizontal baffles
From what I can see,MY recommendation would b
Again to ENSURE as little as possible HOT air is recirculatede to make a small wooden frame
say 50mm deep, the length & width of the condenser
If necessary slot it to fit over piping
Attach two or three Small computer or similar type 12V fans to the under side of the wooden frame
Fit the WHOLE lot as close as you can to the UNDERSIDE of the CONDENSER
Connect ALL the fans in parallel to the FRidge 12Vsupply via a thermostat JAYCAR part #ST3831 Fitted directly to the top of the condensor fins about MIDWAYalong with say a 5Afuse fuse in the pos linewhere you take it off from the FRIDGE 12V SUPPLY terminals
I cannot see any problem with the bottom vent
Except the wiring mess
Could you let me KNOW what the marking are on those terminal blocks???AS I havenot seen the rear of that model !!!
That INSTALL
well & truely FAILED to meet the GAS regs
It is Frightening what some /most van makers do!!!
Come back if necessary AT ANY TIME

Thanks Peter,
I don't have the van at
home at the moment as Dometic are still looking at it. Here is the original
pic which I hope you can see the details of connectors.
The cavity sides are parallel to the fridge and have been packed with insulation material as
well as above the cabinet.
The rear of the fridge is, to my mind too far from the van side also. From memory it could be at least 80mm closer if the copper gas pipe were modified. When I get the van back I plan to pack blocks of polystyrene foam to almost fill that gap. I will also try to get a
pic looking down from the top vent.
The exhaust flue exits the van via a separate outlet which is different to the usual (older) style. I will get a
pic when I get the van back.
I don't know if you are aware but Dometic now actually fit a fan below the cooling fins as standard which, via a thermostat blows upward to help expel hot air.
Thanks also
Ross & Keir, I will let you know how it progresses.
Cheers Neil

HI Neil
80mm is far to much space the current
You should try to fit a full width horisontal baffle level with or just below the condenser fins
Again with the idea of ALL the cooling air IS being drawn through the condenser fins by NATURAL draft as much as possible
But you foam blocks could do the same thing
The boiler exhaust Flue is OK, that is what I hoped for!!

Yes I believe I made reference to that in an earlir post
IT has only taken them something like 40+ years to see its advantage & offer that option
BUt ONE van without good baffling will not do much good
IT will ,to a large extent, recirculate hot air
I did that with my first van's absoption ELECTROLUX fridge way back in the late 50S early 60S
IT was a common practise with absorption fridges, when they became very popular post WW2 ,[old Silient Knight C.Hope's "Cold Flame' etc]all improved when air was forced over the condensor
PeterQ
But GOOD Condenser cooling was recognised looong before that
A OLD coalmining ghost town in FAR Nth Qld,had several large semi coimmercial absorption frigdes laying around that had the condensors immersed in tanks of water which were tricle feed.
That town closed down in 1928!!
ps even with te NEW unit it will pay you to consider ALL the suggested mods
