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.
