Yes, I believe it dissolves anything sensible it comes into contact with.

We could start a new thread on the uses of moronic acid. I have used it on occasion, unbeknownst to me at the time. But after further investigation it became obvious that it was the major ingredient in the mix. It mixes well with alcohol.

To get the temperature right for a freezer propane usually requires about 10-20% butane mixed with it.

Installing a sight glass is a fine idea , but on a boat spend the extra $2. and use an armored sight glass , a built on cover covers the glass area when not being observed.

You might save yourself a little money by finding the leak for the refrigeration mechanic. Always wear eye protection, liquid refrigerants can blind you, best leak detector is a bottle of Mr. Bubble and a small paint brush.
Good Luck

AC supply companies have a goo paint on product that stays together for micro leaks that blow up like a balloon over an hour or 2 that will also tell the tail. I usta be a bubble chaser for the pressurized cable systems with the the phone company and we mostly used soap like mr bubbles...he is right about the bubbles. Putting red dye In the system will also work. Another method, there is oil in there, clean everything with lacquer thinner, acetone..very clean then a day or 2 later or whatever spray it all with aerosol foot power and see what sticks...

Look for the name plate on the unit and see what the refrig type is,.Also amp draw.See what the comp is at when running,and if there is any temperature at the lines. If the suction is cool and discharge is warm then you may still have some refrigerant in the system.Does the cold plate get cold?You can get gauges at a auto part store or harbor freight,but to get the right refrigerant requires a license .R.12is very $$$$$ and R22 is only available with a license here in Florida. You can look for the leak at the flare nuts or any connection were oil is present with soapy water. I would also suspect that the leak was known to the past owner.

Moronic acid is used on politicians.

Lots of funnies with the moronic acid - going back to initial post I made. Update on my old cold plate unit (in '84 GB 42): had a very slow leak at the valve where you charge the unit. Rest of system ok, but all refrigerant had leaked it. Fixed the valve and recharged the system. So far so good almost 2 weeks later.

Glad you found the leak. Our system is 28 years old ('86 GB) and going strong.

I had the same problem, found out that the old Cruisaire charging valve was leaking thru the valve stem packing gland. Re-charged and made sure the valve was back seated and the gland nut was tightened.

Question - does your Cruiseair condenser unit run 24/7 or does it kick off and on per demand?

The water circulating pump that supplies water to the condenser is wired to go stop and start when the thermostat setting stops and starts the compressor. The air blower runs constant.
