Step 1:
Check plug is dry first, then connect lead into power outlet, switch on.
Step 2:
Remove clear cover from timer face by pulling the two black lock pins outward.
Depress the red knob
(Fig. 14)
and rotate anti-clockwise to backwash position,
release red knob, wait for valve drive to index to backwash position, (if not
already in this position) spindle fully out.
(Fig.11).
Step 3:
Just open inlet isolating valve approximately 1.1/2 turns. Allow unit to fill slowly
(water will issue to drain) continue to run until the unit automatically indexes to
Pause position which may take up to 20 minutes. All air must be removed.
Step 4:
Depress the red knob and turn anti-clockwise until the microswitch trips into the
fast rinse position. Allow the valve to move fully into this position
ie. Fig. 13
.
Further rotate the red knob anti-clockwise so that the arrow tip is pointing at
about a seven o'clock position. Then allow the red knob to advance electrically
around to the Service position. This may take up to 10 minutes.
Step 5:
Depress the red knob and turn anti-clockwise to start, release, the unit will now
go through each cycle - Backwash, purge and back to service automatically.
NOTE
:
A small amount of media may pass to drain during the initial backwash,
this is considered normal.
Step 6:
Check with site supervisor that unit can go on line. If so - slowly open outlet
isolating valve fully, check that manual bypass valve is fully closed. This unit is
now on line.
Step 7:
Check for and report any leaks.
Step 8:
Set the backwash frequency to Tuesday, and Saturday for Carbon Filter if
frequency of backwash has not already been calculated. To set, PUSH the
skipper pins IN on the skipper wheel on days Backwashing is required.
Note
: This is only a guide for initial setting and should be altered to suit each
individual installation in accordance with load conditions.
Turn the dial to the correct day of the week on which you are setting the dial. Now
depress the pins for the desired day/s for backwash required.
