6. PRELIMINARY START-UP
After plumbing is completed, conduct the following test to determine if there
are any leaks in the system.
A. Turn main power ON
B. RUN-STOP switch to ON
C. FILL/CLEAN switch to FILL
D. Close cover
Push START button and gradually open the inlet valve you installed in the
rinse line to bleed the air out of the line; them immediately open valve
completely. The unit has a flow control valve which allows 3.5GPM, so it is
important that the inlet valve doesn’t restrict the flow to less than 3.5GPM or
the fill time will have to be increased. After 90 seconds, the fill solenoid will
close, and the water will be up to the overflow drain opening. Possibly, the first
time the inlet valve was not manually opened fast enough to allow 3.5GPM for
the entire 90 seconds. To test the overflow-rinse line, leave FILL/CLEAN switch
on FILL and push the start button and water will flow into tank for additional
90 seconds. Now you can check your plumbing for leaks.
CAUTION: When conducting this leak test, make sure the power module is not
under the plumbing in order to avoid getting the electronics wet.
To test the drain plumbing, move FILL/CLEAN switch to CLEAN and push
START button to start the ultrasonic cleaning cycles (make sure fan inlet and
outlet of power module are not obstructed). The clean cycle will cavitate for 10
minutes before the tank will drain. The entire clean cycle and times are given
in the procedure section. You can stop the clean cycle at any time by turning
the RUN-STOP switch to STOP and the program will revert back to the
beginning of the FILL CYCLE.
