System Components

2.1.1 TruDose Chemical Controller
The TruDose Chemical Controller allows automatic
monitoring and adjusting of pH and ORP (adjusting
requires an optional saltwater chlorinator connected)
levels through a simple, user-friendly interface, resulting
in easier management of water balance in swimming
pools.
It can be easily installed into your existing pool
environment and equipment and monitors and displays
the pH and ORP levels using LEDs and digital readouts
on the front panel of the unit. In addition, four separate
function buttons allow simple pushbutton control of
these individual parameters:
• Mode - Auto (running), pH settings, ORP settings.
• Set level - pH or ORP level to be maintained.
• Dose Time - Dose time (seconds) for pH.
Overfeed time (hours) for ORP.
• pH Cal - pH calibration for variation in pH sensors
The controller has a peristaltic pump that feeds liquid
acid. The acid pump will turn on if the pH measured is
higher than the setpoint defined by the user.
When the ORP measured by the ORP sensor is lower
than the setpoint defined by the user, the controller
turns on the chlorination from the optional saltwater
chlorinator to produce chlorine and reach the desired
ORP. When the ORP reaches the setpoint, the chemical
controller has the ability to turn off the chlorination from
the saltwater chlorinator. The saltwater chlorinator is not
provided with the TruDose chemical controller.
2.1.2 Flow Cell with Flow Switch
The flow cell houses a flow switch and holds the pH
and ORP sensors. These sensors connect to the chemical
controller to monitor the pH and ORP levels in the water.
The flow switch verifies that water is flowing during
a feed cycle and sends the controller instructions to
deactivate the feed if water is not flowing. Operation of
this controller without a functioning flow switch may
result in under-dosing or over-dosing of chemicals.

Other Components

• pH sensor - standard (use only part number
R0894300)
• ORP Gold Sensor - standard (use only part number
R0894400)
• Fittings - for tapping installation of flow cell input/
output
• In-line Filter - install prior to the flow cell to protect
the flow switch and the pH and ORP sensors.
• Tubing - 25 feet of 3/8" and 20 feet of 1/4" for
providing acid to and from the acid tank.
• pH Pump - including tubing and fittings - integrated
peristaltic pump for pH-controlling acid.
• Mounting Board - ABS plastic with mounting holes
and stainless hardware (18" x 10").
• 1/4" NPT tap (included)
NOTE:
Using undiluted acid could lead to corrosion
or overfeeding issues. Use muriatic acid only
(not provided). Dilute the acid 4:1 following
the safety recommendations of the chemical
manufacturer, and use personal protective
equipment. For example: For a 5 gallon tank,
there would be 4 gallons of water and 1 gallon
of muriatic acid.
