 Insert the new O-rings into check valve retaining hole and the hole on the main manifold. Coating the O-ring with a
small amount of silicone grease will allow the check valve to ease into the block easier.
 Insert the check valves into the check valve block, verifying the proper direction. Attach to the main manifold. Insert
the four check valve block retaining screws and tighten the four screws in a uniform manner. Refer to figure 37.
 Repeat the procedure for both main module and the “B” station water & disinfectant manifold.
