Aircon Water-Cooling Pump System

After a bit of tooing and froing with Groco over hose fittings and positioning of the strainer (it can be above the waterline, if the raw water inlet cock is fitted with a shut-off valve), I started on the water supply system for the to-be-bought (either this one or this one) aircon system.

I managed to buy some 1″ (hose is always inside dia, whereas fittings are outrside dia) water hose from West Marine in Corpus Christi and worked out that I could fit the pump and strainer under the sink, both below the waterline.

I was planning to fit the pump vertically, but decided that it could go horizontally. I also toyed with putting the pump in the old fridge compartment, but that would mean drilling bigger holes to route the water inlet hose, which is around 1.5″ o.d. The water hose to the a.c unit is 5/8″ , so around 1″ o.d. – a lot smaller and easier to route.

I need to build a cabinet that will fit into the hold where the fridge used to be. This cabinet will shield the a.c. from the engine bay and from any bilge fumes, so that I don’t end up recycling bad air. The unit will sit in the cabinet, which is to the left of the cooker (the pump is to the right, hence my concerns about routing the water hose). Waste seawater and condensate will be pumped to the transom and overboard.

The pump installation is not quite finished yet, and I may move the strainer to the left and down a tad. But we have progress!
