Dang you have a sharp eye!! Thats a 3/4 strainer which is all I could find on board yesterday. The unit came with a 1" stariner bushed down and of course, it showed up as I was reaching down for the breaker to turn on and fire the unit up. We do have a LOT of grass in the water here, so more capacity is a good thing! Right now the discharge hose is through the clamshell vent until I get the proper thruhull installed.
The little pump took about 5 minutes to fill the system, and after that was a good steady flow. Due to time, temperature and space constraints, the hoses are a little barbaric, but we have air in the master. Of course it dropped down to 65 last night and we didnt even turn it on! Today is beautiful, but I am sure the fireball is gonna nix that later.
I shot you an email yesterday, but I guess you only work part time LOL! The unit is mounted now as pic'd. I tried turning the blower "up" but it wouldnt clear the water pipes… about a 75 degree turn. I returned it to the OEM position and went from there.
So heres some info on the unit… Startup amps are about 24 and she settles down to 22 when on line. Water "in" is 74 F and "out" is 86. Cabin amb. temp is down to about 74 after 15 minutes from 88F with temp in at 75 and out at 57F. The water pump motor case is about 85F. All temps were shot with an IR gun.
Unit was making a fair amount of condensate as it was about 87 RHI. Since I only have a 50A 220 inlet so hotel load sharing is the norm.
Theres some pics on the Flybridge, but I like to post them here too if thats OK. People need to see this stuff to comprehend whats going on. Thanks again for your guidance; it makes it easier and gives me confidence! Bill

Dont ya just love it when somebody sez, " You really know yer stuff…"? We ran that AC for a full day and sure enough, the strainer loaded up with grass. The back of the boat is in 12 feet of water so it must be floatsam. Cleaned it out and all was good until bedtime last nite when the water output was marginal, again. Pulled the screen and it was clean. Opened the valve and NADA. Pulled the hose from the valve and we had a gusher. The 3/4" hose was packed solid with grass. The 3/4 seacock is marginal too I believe.
The inline strainer is a GROCO unit. I installed it with the arrow in the right direction, but find this morning the plastic POS was cast wrong ! Needless to say, the unit wont pass enough water to keep the hose clear. I found my other strainer that came with the AC unit. Still a 3/4 but way more capacity. So now, I am gonna pull water from the adjacent 1-1/2 valve with a 1-1/2" hose to the bigger strainer and reduce it to the AC unit pump from there. It should pass de grass into the screen which I monitor and can clean daily if need be. ws

Par is correct in how they labeled the strainer, but as I tried to explain earlier…They never intended that strainer for your kind of duty….

if you think about that little POS…How would you see debris inside the screen instead of ouside…Oh thats right…That's all that it is, is a screen…It's not a real basket….

How many cleanings/disassemblie/assemblies do you think the little plastic POS was designed for….It's main purpose is to protect a diaphram type bilge pump…Specifically to protect that pump's check valves…It was never built for the volume of debris/water, or continous operation of A/C pump duty….If someone tells you differently…I say they are Full O' Shwrt too…GET RID OF IT !!!….A $15 plastic strainer (screen) is not suitable for protecting a $410 A/C pump…Not to mention it's dangerous, and could turn your boat into a SUB again !!!

There I said it    Now do what you want with it…

So the "new" strainer set up seems to be doing fine. Its the unit that was insatalled with the AC unit from the factory. I have a bad habit of turning the T stat down all the way and retiring for the night. In all reality, it doesnt get any colder, so now I set it for 72-74 and let it go. It probably reaches that and shuts down in the night sometime when I am in a land far far away!! No more frozen intake… ws

also got a pic of the triggers and pump relay (?) I ned to test this as well and see if it picks up AND transfers load.

That is the factory provided strainer (for now) with the 12K unit (!?) Its merely there until I find a 1-1/2" groco unit. This coming week, I am doing a fuel tank wash AND polish job plus an oil change. I'll finally have a chance to look around some of the A.C. stuff.
Looking at the compressors the other day, I found there to be four 110vac units and the biggie 220 unit. I am sure thats the salon unit, and guessing it also feeds the air handler next to the lower helm. (?) The 110 jobs are for the V berth, master SR, Guest SR, and the upper salon that I pulled out last week for the rehab up there.
Heres some tag pics off the units… ws
