Pour in the 1 cup of water (Whether you have potatoes or veggies or not.
Place a large sheet of foil on your counter (It must be big enough to wrap your ham)
Put your ham in the foil. Do not wrap the top. You will leave it open to pour in your sugar and pineapple mixture once it is in the pressure cooker.
Mix the packet ingredients or the brown sugar, cinnamon, nutmeg with 1/2 cup of the pineapple juice from the can of pineapple. You can use the pineapples later or put them on the ham in the pressure cooker. Our kids like their pineapples not cooked with their ham. I like mine cooked so I do half and half.
Then put down the trivet. If you do not have a trivet the sling made of foil or the silicon one will work. If you do not know how to make a sling. This is an excellent post How to Make A Sling
Place the foil wrapped ham on top of the sling
Make sure the foil will contain the liquid you are about to add.
Pour in the liquid mixture.
Close the Foil
Shut the Pressure cooker
Turn it to 10 minutes for your pre cooked ham that is 6-7 lbs
Let the pressure release when it is done
Use your mits to take off the top
unwrap your ham and let it cool
