To those that have replaced their cooling units
What did you do with the old core? I want to cut the old one up but no idea what the internal pressure is. How did you depressurize it ?

- If you're replacing it because it leaked, the internal pressure is the same as atmospheric pressure.
If it hasn't leaked, the internal pressures are quite high, I think I recall maybe 150 psi or more. I'd investigate hiring out the depressurization and ammonia capture if I were in your shoes. Concentrated ammonia is not something you want to be breathing or working with sans proper equipment or training. - Dont cut the old one up!!
I tried that years ago and found out the hard way there is A LOT of pressure in there..
Upon cutting into the line I heard a pop and commercial grade ammonia sprayed my leg and arms (burning) and a cloud enveloped my head. It took one breath to start losing consciousness. Just as my vision went to a tunnel I stumbled out of the garage and got a couple of breaths of fresh air.
I danged near killed myself doing something stupid. - It is illegal to remove the refrigerant here in NY, unless less you have been certified and licensed. Here it causes $30 - $50 to have it done, a small price to be safe see previous post.
- Dispose of it just like you would an old window air conditioner unit. We have a recycling center and cost us $20 to drop off anything with refrigerant in it.
- Got it, thanks... Thats what I was afraid of. With my recent 2 month stay in the hospital thanks mostly to Pneumonia, I am particularity aware of things that might damage whats left. I'll call me HVAC friend and see what he recommends since I'll have two of them by the weekend. I know the Freon rules but not Ammonia, Sulfur, etc.
- The only hazardous substance is the small amount of sodium chromate. The ammonia is really non-hazardous as far as disposal is concerned.
Of course, the sodium chromate is pretty much what the Erin Brockovich story was about. Chris Bryant wrote:

Thanks Chris- 300 PSI........

About 37,000 acres right now. They got control of the west end of the fire last night and are working on the East side over by Agua Dulce/ Acton. There's been a nonstop stream of equipment and personnel coming in and it sure showed yesterday. The suits are finally talking about buying a pair of super scoopers to keep in Van Nuys
300 PSI........

HERE is a time lapse of the death of the West flank yesterday. I put the iPhone in the window and went back to wiring the fridge for awhile- Man- be safe Jeff- given a choice, I'll take floods over fires any day.
