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 contact the manufacturer.)
Sequencing for Various Filters:
Air Filters (Iron & Sulfur)
1. Backwash Air
2. Backwash
3. Regenerant Draw Down (Air draw)
4. Return to service
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
����
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
����
again.
2. Pushing and holding the
�����
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.
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
�����
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
�����
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
�����
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. Turn on a cold water faucet wide open, 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.
