INTRODUCTION:
The Ultra Precise ATO (Automatic Top Off) unit works as either an ATO (Fill
mode) or as a sump pump (Drain mode). It has an integrated peristaltic
pump that is capable of pumping approximately 180 ml/min when
running at full speed. This may be regulated by changing the pump speed
in 10 steps, from minimum to maximum. You may further alter the rate
of flow by changing the Duty Cycle. The Duty Cycle consists of recurring
20-second cycles. The default setting is for the pump to run for the entire
20-second cycle. The user may change that setting to allow the pump
to run for as few as 2 seconds during each cyle, in even increments (i.e.
2,4,6,8, etc.). This feature can be extremely useful to dial in exact dosages
when using the ATO as a delivery pump for Kalkwasser, etc.
There are many advantages to the integrated perstaltic pump. The liquids
themselves never come in contact with the internal workings of the pump.
This contributes to the extremely long lifespan of the peristaltic pump. Also,
since the pump does not rely on the liquid being pumped for lubrication,
there are no deleterious effects if the pump is run dry. The LLC-UPLC-ATO
is also capable of pumping liquid to a level of 60 feet above the pump
itself or 300 feet horizontally. This is very handy if your sump is located on
a different floor or in a different room than your aquarium or if you can’t
mount the pump in close proximity.
The ATO comes complete with a liquid level Sensor Tube which allows
the user to set the levels of operation for the pump. In “Fill” mode, it turns
on when the lower level is reached and turns off when the upper level is
reached. It also includes a separate high limit Sensor Tube which works as
a safety backup system. This sensor operates off of a separate circuit which
will function even if the main processor and/or the pump switch were to
fail. If the water level ever reaches the high limit sensor, the pump will be
de-energized and will stay off until the water level drops below the low
water level that has been set by the user.
The sensor tubes are held in place by a proprietary rustproof magnetic
probe holder. This has been designed to hold the sensor tubes securely in
place on tank walls up to 3/4" in thickness.
FAMILIARIZING YOURSELF WITH THE ATO:
The ATO comes “out of the box” ready to move water from your storage
reservoir to your display tank. The Pump will be running at full speed (10)
and will be constantly ON.
Before you connect the ATO to its Storage Reservoir and Display Tank,
take a few minutes to familiarize yourself with the operation of the ATO.
It is most convenient to locate the ATO near the Display Tank, within the
reach of the two airline tubes that are part of the Sensor Tube Assembly.

You can cut the tubes in two and extend them with 1/4" OD x 1/8" ID vinyl
tubing to an additional distance of fifteen feet.
There are 6 lights, arranged vertically along the left side of the ATO. They
are numbered 0, 2, 4, 6, 8 and 10. They are used in different modes to
display various values and settings.
There are two buttons, UP ( ) and DOWN ( ). They are used to modify
the runtime characteristics of the pump. Repeated presses of the UP button
steps the indicator lights up to light 10. One more press of the UP button
returns to light 0. Likewise, with the light 0 blinking, one press of the
DOWN button will return the display to light 10. This is the most common
way to quickly switch the pump from off to on and back to off.
During normal operation, the lights will indicate the SPEED at which the
pump is running and the state of the pump — on or off. When the light(s)
are solid on, the pump is on, when the light(s) are blinking, the pump is
not running.
When the Primary Sensor Tube senses the water level dropping below
the “lower limit” point, the pump will turn on and stay on until the Primary
Sensor Tube senses the water level rising to the “upper limit” point. At that
time, the pump will turn off and stay off until the level drops below the
“lower limit” point again.
If the water level EVER reaches the high limit sensor tube, the pump will
be stopped and all six lights will blink rapidly in unison until the water level
is lowered.
When power is normally applied, the ATO will quickly go into its main
mode of normal operation. During normal operation, the lights indicate
the SPEED of the Pump in 10 steps, with 10 representing FULL SPEED and
0 representing OFF. Pressing the UP and DOWN buttons step the lights
through the sequence from 0 to 10. There will be some maximum vertical
distance where the pump may stall when it is set to a speed setting of 1.
Increase the SPEED to 2 or even 3 for reliable operation.
During normal operation, the Primary Sensor Tube is positioned in the
receiving vessel so that the expected high and low levels fall within the
length of the Primary Sensor Tube.
FAMILIARIZING YOURSELF WITH THE ATO: (CONT.)
QUICK SETUP
The Quick Setup should be performed with the High Limit Sensor Tube
out of the water and the Primary Sensor Tube inserted into the water as
shown on Page 5.
With the pump off, hold the DOWN arrow button and apply power. After
3 seconds, release the button. All 6 lights will blink three times in unison.
The pump will then start to run in a normal mode with a pump speed of
10 and a duty cycle of 20 seconds. The water level will now be maintained
to within one-tenth of an inch (±0.1") of this point.

SETTINGS
When the ATO is initially plugged in and powered up, the bottom light
(0) will blink rapidly for three seconds before engaging the pump. At this
time, the pump may be set for FILL or DRAIN mode.
NOTE: Setting the high and low levels may be performed at a table using
a large glass of water. We recommend using a waterproof marker
to indicate your set points on the Primary Sensor Tube. This will
assist you when installing the Sensor Tube Assembly in your SUMP.
FILL MODE SETUP
1. Power up the ATO unit
2. Within 3 seconds, while light 0 is blinking, press the UP button for
two seconds, then release it. The three lower lights (4,2 and 0) will
blink in a downward sequence.
3. Position the Primary Sensor Tube in the water at the point on the
tube where you want to set the “lower limit”. This will be the level
where the pump will turn on. We recommend that you set this so
that it is at least one inch from the open end of the tube.
4. Press the DOWN button to set the lower limit.
5. The three upper lights (6, 8 and 10) will now blink in an upward
sequence.
6. Position the Primary Sensor Tube in the water at the point on the
tube where you want to set the upper limit. This will be the water
level where the pump will turn OFF. We recommend that you set
this between 0.2 to 4 inches above the lower limit point.
7. Press the UP button to set the upper limit.
8. All six lights will turn on briefly to indicate success. These settings
are remembered even after power is removed from the unit.
DRAIN MODE SETUP
1. Power up the ATO unit
2. Within 3 seconds, while light 0 is blinking, press the DOWN button
for two seconds, then release it. The three lower lights (4,2 and 0)
will blink in a downward sequence.

SETUP: (continued)
3. Position the Primary Sensor Tube in the water at the point on the
tube where you want to set the “lower limit”. This will be the level
where the pump will turn OFF. We recommend that you set this so
that it is at least one inch from the open end of the tube.
4. Press the DOWN button to set the lower limit.
5. The three upper lights (6, 8 and 10) will now blink in an upward
sequence.
6. Position the Primary Sensor Tube in the water at the point on the
tube where you want to set the upper limit. This will be the water
level where the pump will turn ON. We recommend that you set
this between 0.2 to 4 inches above the lower limit point.
7. Press the UP button to set the upper limit.
8. All six lights will turn on briefly to indicate success. These settings
are remembered even after power is removed from the unit.
DUTY CYCLE SETUP
1. Power down the ATO unit.
2. Press and hold the UP button
3. Power up the ATO unit
4. All six lights will flash twice to indicate that you are in Duty Cycle
Mode, then one or two lights will blink rapidly, indicating the
current setting for Duty Cycle Mode. (See Page 7 for explanation.)
5. Press the UP and DOWN buttons to adjust this setting.
6. To quit this setup mode, simply remove power from the ATO. This
setting will be remembered.
SETTING PUMP SPEED
During normal operation, the lights will indicate the SPEED at which the
pump is operating and the state of the pump — on or off. Solidly lit lights
indicate that the pump is running; blinking lights indicate that the pump is
not running. In both instances, the lights indicate the SPEED setting of the
pump. Whenever the pump is running, you may use the UP and DOWN
buttons to adjust the pump SPEED. (See Page 10 for further details.)

PUMP SPEED SETTINGS
The pump has been set at the factory to run at full
speed when you first turn it on. At this setting, it
will pump at the rate of about 180 ml./min. This
may be adjusted in 10 steps. Step “1” is as slow as
the pump can safely run. When set at Step “10”,
the pump is running at full speed. During normal
operation, the lights will indicate the speed of the
pump. You may use the UP and DOWN buttons
to adjust the speed of the pump. When two
adjacent lights are lit, it indicates that the step is
the number between these two. (e.g. If the lights
next to 6 and 4 are both lit, the pump is running
at Step “5”.)
NOTE: The High Limit Sensor Tube acts as a safety
backup. It is on a separate circuit that will
operate even if the main processor and/or the
pump switch were to fail. If the water level
reaches the High Limit Sensor tube, the pump
will stop and all six lights will blink rapidly in
unison until the water level drops back below
the level of the High Limit Sensor tube. If the
processor is disabled, the pump will still turn
off but the lights will not blink.

DUTY CYCLE SETTINGS
Duty Cycle is a function that will limit the time the pump is on in a 20-second
recurring period. This function adds more precision when controlling the
amount of liquid that is being pumped.
e.g. Typically, when the LLC-UPLC-ATO is running at full speed, it is
pumping about 180 ml./min. (2.85 gallons per hour). If the Duty Cycle is
set to “1” (2 seconds), the overall rate will be about 18 ml./min.

Duty Cycle Duration Times
These values represent the number of seconds the pump
will run during a 20-second duty cycle. The number values
are doubled since this is based on a 20-second duty cycle.
When two adjacent lights are lit it represents the value
between the two numbers.
NOTE: The Duty Cycle will not allow a setting of 0 seconds.

SYSTEM STARTUP
1. Before installing your ATO, turn the unit on and run it dry for 20
minutes in order to break the pump in.
2. Use 1/4" tubing to connect the Storage Reservoir to the rubber
tube end of the ATO.
NOTE: Be sure the tubing cannot escape from the Storage Reservoir.
3. Push the tubing into the end of the rubber tubing on the pump.
4. Use 1/4" tubing to connect the right angle fitting on the ATO to
the Display Tank. Firmly push the tubing into the quick connect
fitting until it hits the bottom of the fitting.
NOTE: Be sure the tubing cannot escape from the Display Tank.
5. Mount the Sensor Tube Assembly to the side of your Display Tank
or sump. (See diagrams on Page 5.)
SERVICING THE PUMP MODULE:
These instructions apply to ALL SpectraPure Pump Products. It is
recommended that the pump head be inspected and cleaned, or the
tubing replaced per the following procedure. (Refer to images on pages
14-15)
1. If you are just inspecting the pump head, it is not absolutely necessary
to disconnect the two tubings from the head, but it might make this
task easier (Fig. B-1).
2. Use the provided 3/32" Allen Hex Key to remove the three bolts in
the pump head and lift the pump head away from the motor shaft.
(Fig. B-2)
3. Remove the three white rollers from the pump head. (Fig. B-3)
4. If they are dirty, clean the three white rollers, tubing, head and base
plate with a cloth soaked in De-Solv-it®(available in most grocery
stores), acetone, or petroleum spirits. Make sure you remove all
gummy deposits, then rinse parts with water and dry. Next, wipe
the motor shaft clean. Be careful not to spill solvents on the plastic
case or it will damage the finish. Keep cleaning fluids away from the
bearing at the base of the motor shaft.

5. If you are replacing the tubing assembly, remove the tubing from
the pump head as shown in Fig. B-4. Replace the tubing assembly
with a new tubing assembly. Reinstall by firmly inserting the tubing
into the outlet port of the pump head as far as possible. (Fig. B-5)
6. Pinch the other end of the tubing and insert it through the slot at
the inlet port of the pump body. Manipulate the tubing so that it
conforms to the inside diameter of the pump body. Be sure that the
tubing is completely pushed down into the output port so the tie-
wrap is within 1/16" of the pump body and the plastic “wear strip”
is positioned to the inside so the rollers will contact the wear strip
evenly. (Fig. B-6)
7. Place two of the three rollers into the pump body, pushing them
against the tubing. (Fig. B-7) Hold them in position with your left
thumb and then push the third roller into place. (Fig. B-8)
8. Carefully line up the locator pin with the slot in the inlet port. (Fig.
B-9)
9. Press the pump head firmly against the pump plate and check for
proper alignment. (Figs. B-10 and B-11) Use the 3/32" Allen Hex Key
to reinstall the three pump head bolts. (Fig. B-12)
10. Replace the union connector on the output port stud. The final
assembly should look like Fig. B-1.
11. Run the pump dry for 20 minutes. Be sure to observe the rollers
revolving around the rotating motor shaft through the hole in the
end of the pump head.

TROUBLESHOOTING:
Excessive Noise
1. Make sure that the Pump Module is not attached to or sitting
atop a box or enclosure that will act as a “speaker” and amplify
the vibration of the pump.
2. Secure the attached tubing so that it does not vibrate against
nearby walls, cabinets, or other objects.
No LEDs are lit
1. Replace power supply
Lights are on but rollers are not turning
1. Look through the observation hole at the end of the pump head
and see if the shaft is turning. If not, call SpectraPure Technical
Support.
2. If the shaft is turning, follow the instructions on pages 12-13 for
servicing the pump head.
Pump is running and rollers are turning but no fluid is being pumped.
1. Check the ends of the tubing for obstructions.
2. Check for a loose connection on the suction side which will
cause the pump to lose its prime.
