3030226 Rev. D 3-10 System Operation
7. Once the product water temp reaches 176°F (80°C), the heaters cycle ON/OFF
maintaining the system at temperature for 30 minutes. The hold timer will
count down displaying the amount of heat hold time left in the cycle.
8. After the hold time is complete, the RO cools by convection or by introducing
small amounts of RO feed water. This is dependent on the cooling method you
have activated. When in Cool Down the operator can toggle between fast cool
and slow cool. When the ACTIVATE SLOW COOL or ACTIVATE FAST COOL is
grayed out, that indicates it is operating in that mode. To change, press the
green screen button and it will change cooling mode to the one selected.
9. After the system cools to a temperature of 120°F (49°C), the screen moves to a
POST HEAT RINSE screen. If the RO is in Fast Cool and water and drain are
supplied, the machine will automatically start in POST HEAT RINSE. If the RO is
in Slow Cool, the operator must connect the RO feed water and drain and press
START to begin the post heat rinse.
