STARTUP INSTRUCTIONS
FLUSHING OF SYSTEM:
To flush the system of any debris and air after installation is complete, please perform the following steps:
1. Rotate bypass handles to the bypass mode (see Fig. 2 of page 4).
2. Turn on inlet water and check for leaks in the newly installed plumbing.
3. Fully open a cold water faucet, preferable at a laundry sink or bathtub without an aerator.
4. Wait two to three minutes or until water runs clear, then turn water off and follow start-up instructions.
System regeneration sequence is in the following order. Some sequence differences may be noticed depending upon
local conditions. (If it is desired to change this sequence, please refer to the Dealer Manual or contact the manufacturer.)
Sequencing for Various Filters:
Air Filters (Iron & Sulfur) Backwashing Filters (Carbon & Turbidex) Acid Neutralizers (Calcite & Corosex)
1. Backwash Air 1. Backwash 4. Rinse 1. Backwash 5. Filtering
2. Backwash 2. Rinse 5. Return to service 2. Filtering 6. Rinse
3. Regenerant Draw Down (Air draw)
3. Backwash 3. Rinse 7. Return to service
4. Return to service 4. Backwash
The system is now ready for filling with water and for testing for Air Filters.
NOTE: The “filling” sequence below represents the start-up procedure for Air Filters.
Please reference “Sequence for Various Filters” for proper regeneration sequence (shown above).
1. Place the bypass valve into the bypass mode (Fig. 2 on page 4).
2. Press and hold the REGEN button until the motor starts. Release button. Put the valve into “BACKWASH” position.
(Please see note above.) Unplug the transformer so that the valve will not cycle to the next position. Open the
inlet handle of the bypass valve very slightly allowing water to fill the tank slowly in order to expel air.
CAUTION: If water flows too rapidly, there will be a loss of media to the drain.
Certain medias such as carbon, or other dry medias, should not be backwashed
immediately for extended periods of time. These medias need to “soak”
in the water for a 24-hour period prior to full backwash conditions.
Dry media exposed to water too quickly in backwash will result in media plugging
the drain and valve assembly.
3. After the water is flowing steadily to the drain, clear and without the presence of air, slowly open the inlet valve. Restore
power and momentarily press the REGEN button to advance the control to the “REGENERANT DRAW DOWN” position.
4. With the bypass still in the diagnostic mode (Fig. 3 on page 4), there should be a slow flow to the drain.
5. Press REGEN button in sequence until display returns to “TIME.” Place bypass valve in the normal operating mode
(Fig. 1 on page 4) by opening the outlet bypass handle.
6. CONDITIONING OF MEDIA:
To flush any remaining debris and air from the system again:
1. Full open a cold water faucet, preferably at a laundry sink or bathtub without an aerator.
2. Wait two to three minutes or until water runs clear, then turn water off.
3. Turn on hot water and check for air, then turn water off after air is discharged.
7. Place unit into regeneration and allow to complete a full cycle. Upon completion, unit will deliver treated water.
Inch Worm Feature:
Air filter units are programmed with the backwash air
cycle feature (nicknamed “inch worm”). This unique
feature allows for small movements or “inching” of
the piston towards the backwash cycle. As the piston
approaches this cycle, the backwash port opens slightly
with each advancement, allowing air to escape to
drain. This cycle is twelve very small mini steps of the
piston which take place twenty seconds apart. Usually
midway between the twelve positions, the air begins to
be released very slowly to the drain in normal operating
conditions.
When first starting up an air sulfur or air iron, it is advised
to step through these positions and go to the normal
backwash cycle in order to fill the unit.
To Advance in Backwash Air Cycle:
1. Pushing the NEXT button will advance to each of the
twelve mini steps within the backwash air cycle. While
there are usually twelve steps to this cycle, the valve
may make two or three movements for each step. Wait
for these movements to complete before pressing NEXT
again.
2. Pushing and holding the REGEN button for three
seconds while in the Backwash Air cycle will skip the
remaining mini steps and proceed to the next cycle of
regeneration which is usually Backwash.
