CO- 4.1.0 CENTRAL DELIVERY (SDS) CHECK VALVES INSTALLED?

a) Remove the hydraulics from the cabinet!

b) Figure (below), if check valves (with white inserts) are installed in the Acid and / or Bicarb Pump input

and/or output tubing REMOVE them completely and reattach all tubing with straight fittings!

CAUTION! The check valves at the UF PUMP must NEVER be removed.

c) See procedure number CO- 4.2.0 (page 376).
