Step 1: Check plug is dry first, then connect lead into power outlet and switch on. Check
that the brine throttle/stop valve is closed.
Step 2: Fully open the control valve electrical cabinet cover and hold in this position with
a temporary tie cord. Depress the red knob (Fig. 5) 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).
Depress red knob and rotate anti-clockwise to brine position, release, wait for
valve drive to index to brine position. Depress red knob and rotate to brine refill
purge position and release.
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
Service position which may take up to 10 minutes. All air must be removed.
Step 4: Open brine throttle/stop valve approximately 1.1/2 turns, fully open inlet isolating
valve. Open the cold water isolating valve and allow brine tank to fill until brine
float valve shuts off. A period of four (4) hours soaking should elapse after filling
with water before commissioning to allow the brine to saturate. Depress the red
knob and turn anti-clockwise to start, release, the unit will now go through each
cycle - Backwash, brine rinse, purge and back to service automatically, the full
cycle will take approximately 90 minutes.
NOTE : A small amount of media may pass to drain during the initial backwash,
this is considered normal. When unit commences brine and rinse cycle, adjust
brine throttle/stop valve to the correct draw down rate.
The draw down rate is determined by dividing the float setting height, selected
from Table 5, by 20. eg if 300mm is the float height selected, the draw down rate
is 15mm per minute. Draw down is measured with a tape measure in the brine
well, and is the distance in ‘mm’ that the brine level drops in one minute.
Step 5: 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 6: Check for and report any leaks. Go to nearest tap, now on soft water, open and
allow to flow for a few minutes. Using test kit to test for soft water - refer testing in
back of these instructions. It may take several minutes for the soft water to pass
to the tap. If hard water persists refer to the Service hints in these instructions.
Check that the brine tank is full and that the float has shut off.
