1) Remove Adaptor A-15 with product hose P02 from the "First Pass Product
Water" distribution tank and quickly cap the tank inlet.
2) Remove adaptor A-15 and connect the product hose (P02) to the inlet at the top
of the NBC tank. Up to three hoses may be used.
CAUTION
Do not connect the product hose to the 2nd distribution tank until verifying the
product TDS and Chlorine.
3) Connect one end of the product hose set aside earlier to the outlet at the bottom
of the NBC tank. Place the other end near Adaptor A-15 on the 2nd distribution
tank. If two hoses are required, use the second hose set aside earlier.
