What To Do
• Complete the Sanitizing Procedures on page 15.
• At completion of regeneration cycle (approx. 2 hrs), run water
from faucets to purge the salty water.
Check pressure.
• Drain height 8' or less, pressure should be minimum of 20 psi.
• Drain height above 8', pressure should be minimum of 50 psi.
• Clean and reconnect drain line.
• Check for kinks in drain line.
• Complete the Sanitizing Procedures on page 15.
• This is normal. High water flows in backwash cycle, flushes
minerals and sediments from resin tank.
• This is normal.
• This is normal. This is the sound of various valves opening and
closing as valves cycle through regeneration cycle.
• Will go away after it runs for a while.
