<1>Wait for 10 seconds on power supply before start the system. Flush for 1
minute, and 30 seconds flush after tank with full water. Before the next water
production, flush for 15 seconds.

B. Preset value for motor water making time.
C. Motor outlet pressure and flushing pressure steering (YES, NO).
D. Standby flushing time setting(YES, NO).
E. Fixed compulsory flushing.

1. Depress setting key 3 seconds to enter setting mode, the first display TDS (
000PPM)setting, then press the second display motor water making time
setting H00(YES,NO), then press the third display motor outlet pressure
and flushing pressure P=0 setting (YES, NO), than press the fourth display
full-water standby flushing F00 setting time (YES, NO).
2. To change settings, select a required mode display window, press (flush / 0
adjustment) to change settings value, automatically restore to normal
display after 5 seconds to represent setting is completed.
A. TDS vate be set from 000ppm to 100ppm.
B. Water production period set from H09 to 99. Hoo represents invalid
function.
D. Under full-water standby, it can set (F01-12) hours for flush setting, and
flushing action time is 1 Minute or setting (F00) this function as
ineffective.
Note: setting time automatic flushing to prevent machine from no
operation for long time.
E. When power is off, depress setting key and strong flush key without
release, then energize to wait the display flashing with bi sound, then
release, after 13or bi sounds starts to control fixed flushing action to
conduct film pipe acid washing action, when power is turned ON / OFF it
restores to normal operation action.
F. Manual forcible flushing should require to depress strong flush key

Note: such function is to protect water tank from making water without
stopping caused from abnormal operation on switch.
C. Motor outlet pressure and flush pressure setting(P=1, 0), (P-1
represents action, P-0represents malfunction).
Note: such function is to protect when motor makes water but fails to
achieve normal pressure to cause Motor idle running and to stop water
making.
