Re: New Thread on A54 fridge pumps (ATTN: OLIVER Vela Nautica)
Porter, According to Frigoboat, the pump selected should move at least 6 liters/min. A 24-volt pump rated at 12 liters/min. running half speed on 12 volts will pump about 6 liters/min. I am not the electrical expert that Dean Gillis is, but I will try to answer your question. In this schematic, the relay has a 12-volt coil that activates an internal switch. The switch could switch either 12 volts or 24 volts. In the schematic, you will note that only the positive is switched. Dean, feel free to edit or correct. That relay in the schematic is a very ordinary "Bosch style" normally open 4 pin relay which uses 2 pins (85 & 86) to activate the coil, meaning when 12 volt positive is connected to 85 and 12 volt negative is connected to 86, a switch is closed between 2 pins (30 & 87). There are 2 types of 4 pin relay available; normally open or normally closed. A normally open relay will switch power ON for a circuit when the coil is activated. A normally closed relay will switch power OFF for a circuit when the coil is activated. You want a normally open relay for this project. To further confuse, there are 5 pin relays which allow either normally open or normally closed depending on whether you use 87 (normally open) or the fifth pin 87a (normally closed). This is a package of 6 4-pin relays with sockets and wire: https://www.amazon.com/PACK-Pin-SPST-Relay-Harness/dp/B07X1R18QS/ref=sr_1_1_sspa?dchild=1&keywords=Relay+4+Pin&qid=1594563018&s=automotive&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExVzkxWjQ5OTBBMjcyJmVuY3J5cHRlZElkPUEwNjYyMDMxMlA0MU85WDRTVURSNCZlbmNyeXB0ZWRBZElkPUEwNjEwNTc4OUdOQVJGUVQzVDdPJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

Re: Is there a valve for the water intake for the washing machine?
Along the same lines, I had a sink faucet fail last year, and had no way to shut water off to one faucet. On my list is to put a shutoff valve on every faucet. I didn't know there was a shutoff valve for the washer. Gotta find that. Kent Sm243 Kristy

Re: New Thread on A54 fridge pumps (ATTN: OLIVER Vela Nautica)
Hi Scott,
Yes, it does seem a bit counter-intuitive that warmish water is more efficient than cold water. Here is a paraphrase from my system's technical manual that may help in understanding it. The reason (that 90F sea water is optimum) is that in the refrigeration cycle, after the high pressure liquid refrigerant has passed through the expansion valve and gotten cold by converting to a gas, then passed through the cooling coil and taken on the heat of the refrigerated area and then gone back through the compressor, it is about 140F and only needs to be cooled to about 120F to condense back to liquid and repeat the cycle. Thus 80-90F cooling water is all that's needed. In colder water the liquid refrigerant is too cold and is stored in the condenser and the system operates with a much lower suction pressure as the pressure difference across the expansion valve is reduced. This will substantially decrease the capacity of the system and increase the running time. That same manual offers corrective solutions for operating in cold open ocean water by using a gate valve or a water by-pass to restrict the flow of too cold water and get the drier and receiver temperature up to about 95F. From just an everyday non-technical vantage point, consider that the marine market is absolutely insignificant to the global refrigeration market (no special refrigerants, etc. - there is no such thing as "marine refrigeration" outside of the marketing department). Nobody has cold water cooling - Eskimos don't need it! Household refrigerator cooling coils have ambient temps in the 70's or 80's or more (room temp). Apartments and buildings have water source cooling tower ambient temps in the 80's and 90's (or 100's here in Florida) and, therefore, cooling water temps are the same. Those systems are, in fact, at maximum efficiency because they are providing cooling at the condensing temperature of the refrigerant - 80 to 90 ish, depending on the refrigerant. And, oh by the way, I just Googled Windy.com, clicked on the water temperature, and from 20 S to 20 N, including the entire Caribbean, the water is in the 80's. At my dock in Florida it's 92F. My A/C and refrigerator love it! As do all those cruisers who used to be there before Covid. I would assert that no marine refrigeration system is designed to operate in extra-tropical ocean cold water temperatures - unless it has a gate valve or by-pass for cold water use. That pump life has been seen to be inversely correlated to ambient temperature is perfectly understandable. It's not the cold cooling water, it's the cool ambient temperature. The cold cooling water is actually increasing the running time and fighting against the cool ambient temperature that is decreasing the running time. It would be fun to experiment with a system with a gate valve or by-pass valve in a cold place. Run the system with 55 degree water for a few days and log the run times. Then throttle down the valve to get 95 degree water for a few days and log that. Then check Oliver's fancy logging system and see what it shows. Dollars to donuts the warm water will see less pump usage. Fun topic for a locked down Covid evening, thanks for initiating the discussion, Cheers, Craig

Re: Hardtop for Amel 54
Hi Mohammed, Thank you for the info, Unfortunately I will not be going to the US for some time. My thoughts are that we are going to be here for some time. I really like the hardtop on Caduceus, I will look into this, will need a stainless steel welder, a fibre glass moulder and a canvas/sail maker. Could be a challenge here in Le Marin! By that I mean that getting work done is a challenge and slow, took 3 months to get 4 brackets made for my new lift up windscreens, The early 54's only had one hydraulic lift arm on each lift up screens at 300N, I am changing to two hydraulic lift arms per screen as per your 54 at 170N each. If I was still in Greece I would be able to find these workers, Preveza has a young chap, very good at stainless work. The hardtop on Ruedi and Sabina's Amel 54 might be insulated. Contact Ruedi and he will give you all the info. It looks very well made. Very Best Barry and Penny "SV Lady Penelope II" Amel 54. #17 Sainte Anne anchorage Martinique

Re: New Thread on A54 fridge pumps (ATTN: OLIVER Vela Nautica)
Scott SV Tengah
HI Craig,
I'm a little surprised that you're stating that our water cooled Danfoss refrigeration systems perform optimally with water temps above that which we experience in the tropics. That begs the question - why didn't they design it for maximum efficiency given a water temperature that you would actually experience in the ocean? My primary concern is pump life, which is directly related to pump duty cycle. Oliver logs his pump duty cycle (fancy computerized system) and noted that it went from 15% in colder waters to about 75% duty cycle when he got to the Caribbean. I surmise the hot ambient air temps around the cooling box contribute to that, but for the purposes of comparing pump life for those in warm climates vs. pump life for those in cool climates, pump life seems to be inversely correlated with temperature. Those reporting super long pump lives seem to be in colder areas. While I don't have Oliver's fancy logging system, I can attest that our refrigeration system uses considerably more power per day and our pumps lasted for much less time when comparing our experiences in the Caribbean vs. the Med. That implies to me that, when all is considered, colder temps mean the system is running less often. -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com

Re: Is there a valve for the water intake for the washing machine?
Willem Kroes
Thank you Bill,
I found the valve behind the cleaning stuff. I did not expect it on this side,but must admid that I failed to consult the manual. Anyway, the problem is solved (also with the water intake valve at the washing machine side). I am very happyt to be on my boat again after so many months of lock down. The Greek authorities made a great leap foreward with their digital system. There are also some very reliable Greek websites for updates on the Covid-19-situation in Greece, like this one: https://www.atoz-guides.com/coronavirus-in-greece-update/ Thanks again and stay healthy!

Thanks Barry;
I got permission from the previous owner of Caduceus A54 #56 to share the pictures of his hardtop. The following is the link to the pictures.
https://www.dropbox.com/sh/fr8okwqm43p6hsb/AADBRqNQw4VXvNSKDCVNT4afa?dl=0
Martin circumnavigated with this design and was very happy with it. I now see that Emek Marine has also installed one on a 54 in Turkey. Here’s the link:
The hardtop makes sense in a lot of ways. As shown in the new Amel designs. I’m very interested in finding out your daily average Amp Hour output from your solar panels on your bimini top. This is where we would like to install ours and avoid an arch and the associated weight and interference with the sleek design, on the transom.

Hello dear Amelians,
Finaly on board again of my SM in Greece, I want to start sailing today, but there appeared a small problem. The inlet valve of the washing machine will not close for 100%. So I looked for a valve in the water intake line. I can't find it. Is there a valve (like the one for the dish washer; this one is easy to see)?
