  2. PREPARATION FOR QUICK LIFT AND FURTHER TESTING
    • Attach stream straightener and water choke valve to front 2 ½" discharge on panel side
    • Attach (2) 100' 2 ½" hoses to far side outlets
    • Attach (1) 50' 2 ½" hose to panel (1250 GPM
    • Attach (2) 50' 2 ½" hoses to panel (1500 GPM
    • Attach proper tip to collector nozzle (as found on chart
  3. QUICK LIFT TEST
    Water should attain pressure in a maximum of 30 seconds for?
