Turn on the main disconnect switch and start a stopwatch.
IT:1-2 Does water flow from BOTH the float cylinder rinse nozzle and the 3-way
valve drain port?
IT:1-3 Does water flow from EITHER the float cylinder rinse nozzle or the 3-way valve?
IT:1-4 Does water flow through the float cylinder rinse nozzle?

NOTE: When electric power is turned ON at the main disconnect switch with the
panel ON/OFF switch OFF. an automatic 3-minute blow-down cycle starts. Use
the stopwatch to check that the 3-minute timer stops the blow-down cycle in three
minutes.
NOTE: During the automatic blowdown cycle, the water fill, rinse, and drain
valves are open. Fresh water flushes the float assembly and drains into the steam
generator. Water rushing through the 3-way drain valve pulls water from the steam
generator (Refer to Drain Valve Operation on page xx).
If water flows from BOTH the float cylinder rinse nozzle and the 3-way valve
drain port; the 3-Minute Timer, the water fill, rinse, and drain (3-way) valves are
functioning properly. Continue the procedure with test IT:1-6.
During the blowdown cycle, the 3-Minute Timer activates the fill
NOTE:
and rinse solenoids opening the valves. If the timer malfunctions neither
solenoid will activate and open its valve.
No water flow from both the float rinse nozzle and the 3-way valve
indicates three possible malfunctions:
• The 3-Minute timer is malfunctioning.
• Both the rinse and fill solenoid valves have failed simultaneously.
• Both the rinse and drain solenoid valves have failed simultaneously.
A single component failure is more probable than a double, simultaneous
failure.
Test the 3-Minute timer according to component test CT:2.
1.
2. If the 3-Minute timer is working properly according to component test
CT:2, proceed to IT:1-4. and begin testing the fill solenoid valves.
If water does not flow through the rinse nozzle:
1. Check the rinse nozzle, solenoid valve and associated plumbing for
blockage.
2. If the float rinse nozzle, plumbing, and valve are not blocked, refer to
component test CT:3 and test the rinse solenoid valve.
