Hi Jesper Do you have pictures of the evaporator and the routing of the tubes from the compressor? Kjeld

Kjeld,
The evaporator has the exact same measures as the original one. I mounted it in the exact same position. I even kept the blue "cold plate". The routing of the pipes were pretty straightforward. On the second last picture in my previous post you can se how the pipe is routed behind the fridge (covered with insulation) and then thru the bulkhead where the ventilation duct use to be. The 3rd picture shows where the compressor is mounted. On the same picture you can se a amp-meter and a nipper. They are located on the section of the sofa that I removed. So, first picture is taken from the saloon with that section of the sofa removed. The thrue hull is located in the same position as the old one but drilled to right size. I drilled a few holes from the storage where the compressor is located for the pipes. Finally I secured the pipes with cable ties. Jesper

toholthe,
Looks great! Did you add door switch for both lid an door? I would also consider connecting the fan to the compressor terminal for fan. Then it will only run while the compressor is running and doors are closed. Jesper

Hi Toholthe
Many thanks for this. All looks good - but as you say a little more expensive at around GBP620 vs GBP450 for AGM. One concern I'd have is the ability of the Mastervolt Chargemaster 12/50-3 to handle the combination of both AGM & Li-on batteries. I'd still have 3 AGM batteries left (engine & 2 thrusters) after changing out the 2 house batteries. Best wishes Richard |

Jeb,
The fan is connected to the light in the fridge. It will still run if I open the lower door.
Richard, You need to go trough the charging when switching to lithium, but I did not change anything. I have a Sterling charger with three outputs. Works well.

Toholte: I made the same observation as you that the fridge gets good and cold - but has a hard time when full. Considering putting in a fan like you did. How did it work out for you? Have you been able to maintain a lower temperature when full with the fan?

Hi,
A fan helps circulate the cold air underneath the evaporator. I changed to a “PC fan” which is connected to the steel bar wall just inside the door. I believe it helps to keep all parts of fridge cooler, but not the power consumption.

Hello everyone. I'm talking to you with a translator because I'm not good at English. I have a Hanse 400 from 2006. Would anyone have made a modification under the freezer to evacuate thawing water?

Putting a properly functioning thermostat and an internal air circulation fan has made huge difference to my H315 fridge. My fan is a brushless motor 12v PC fan runing on abut 6 volts, its very effective witout adding much heat. Check my post :- note your Arduino program should/must allow a waiting time; in order that the compressor only pumps gas. The main reason of poor performance with old aneroid capsule type thermostat was short cycling, turning on compressor too early. Regards Perry Cowes, Isle of Wight UK
