Has anyone had any experience of problems with Cruisair air con, if so what do I need to look for/check I am looking at buying a new[to me]ship with this installed..
Who would be the dealers on the South Coast?
 
Cruisair is Dometic yes?

I've had a couple of problems. A control board failed, the one mounted on the compressor, plus I have an as yet undiagnosed problem that the saloon unit just stops sometimes, and resets itself later. I assume its an overheat, but have checked the cooling water flow and its fine.
 
If your condenser side (cooling water) is OK you may find that it's cycling on its low (refrigerant gas) pressure switch. Often high pressure cut-outs are manual reset where as low pressure switches can be auto-reset. Get a fridge engineer to check it for leaks and trim charge if required. Could also be cycling on compressor overload or a faulty room thermostat!
 
Dometic, is airsystems as well, dont know if they are cruisair.

Just fitting an airsystems 12k BTU, unit seems simple enough.
 
I have 2 Cruisair boxes - supplied new with the boat in 2001.
Use them frequently - even in Brixham!
The one in the main cabin as been perfect. The one in the saloon:
a) always been perfect on heating
b) frequently ices up when trying to cool (not enough flow from the fan to keep the fins from blocking with ice). It then cycles to melt the ice and clear the fins.
c) The base trays on 2001 variants (and earlier) were steel, which rust easily and aren't made for replacing.........they switched to stainless on later models I hear.
But most aggravating to me
d) Quite frequently the mains water pump (impeller type) won't get the raw water flowing through...... This is either an installation issue (pump not low enough - it won't suck) or the wrong type of pump (should be a flexible vane pump)...

That's my 2 cents! Definitely worth having though!!
 
With regard to your system B): In cooling mode if the evaporator section (usually indoor - heat absorbing section) is icing up, this can sometimes be due to a lack of refrigerant charge which lowers the pressure in this part of the system and hence evaporating temperature. Parts of the coil then drop well below the due point temperature of the air passing over it, which condenses forming ice. The ice starts to block the flow of air further across the coil reducing the load, exacerbating the problem. It can also sometimes be due to over condensing, due to too much sea water flow through the condenser coil. This lowers the high pressure side too much with a corresponding drop in gas pressure to the low pressure side, causing a similar problem! Offered just in case increasing the air flow does not cure your problem!
