of polymer. This rate may be adjusted during operation to improve
clarity.

q.
Set SODIUM HEX valve to RUN position (fig. 2-66).
r.
Check that the vent product water valve (fig. 2-6) is in the OPEN position. The vent product water valve
allows air to escape from the product water line and lowers product water pressure. It should be closed once product
water has been produced.
s.
Check that the REGULATE PRODUCT flow valve (3, fig. 2-67) is fully open.
NOTE
You are now ready for full operation under normal circumstances. A few
more adjustments are required while you produce water and store it in
tanks for future use.
t.
Slowly close VENT VESSELS valve located behind VENT VESSELS outlet. This allows filtered water to
enter R.O. vessels.
