A number of Flotec pump manuals are available here: http://www.flotecpump.com/ResidentialResourcePage_resourcepage_ownersmanuals.aspx
. The site lists a FP4022-10 pump with the direct link to the manual here: http://www.flotecpump.com/resources/images/514.pdf
For this type of pump, there should be a priming plug or priming tee. Remove the plug (or tee) and pour water into the pump. Keep adding water until the pump and all of the piping to the well is full of water. If a priming plug or tee was also added on the suction side of the pump, open that section and fill all of the piping on the suction side with water. Replace the plugs/tees then open a faucet in the house. Start the pump. After 2-3 minutes, turn off the pump if no water has come through the unit. Add more water through the priming plug or tee (or multiple plugs and tees). Then repeat closing the priming ports and start the pump after opening a faucet. Once the pump is actually pumping water, turn off the open faucet. Wait for the pump to shut off once it reaches full pressure. Open one or two faucets to check that the pump is properly sensing the pressure changes and maintaining system water pressure.
If the unit didn't pull water from the well, check the piping for air leaks. See the full trouble-shooting guide in the manual. Page 9 has the priming information and page 10 has the trouble-shooting guide.
I hope this helps.
