II. Unpacking
The Advantage MicroTron™ pump has been shipped to you as a complete metering package, ready for
installation. If shipping carton shows any signs of damage, notify the shipping company immediately upon
receipt. Advantage Controls cannot be held responsible for damage from shipping. Unpack the carton
and insure that the following items are present:
1. Metering pump
4. Instruction manual
2. Suction, discharge and prime tubing
5. Injector fitting
3. Foot valve and weight
6. Conductivity probe assembly
III. Safety Considerations
NOTE: All MicroTron™ pumps are primed with water before leaving the factory. If the pumped
solution is not compatible with water, disassemble the fluid end and dry before use.
A. Chemical Compatibility
MicroTron™ metering pumps are designed to work with most liquid chemicals. A chemical resistance
chart is available for determining specific compatibility with a wide variety of chemicals. If you have
further compatibility questions, contact Advantage Controls service department at 1-800-743-7431.
B. Safety Equipment and Preparation
Always wear the proper protective clothing and gear when working around chemicals and chemical
metering pumps. Safety glasses, gloves, and aprons are critical in preventing accidental exposure
to dangerous chemicals. Liquids under pressure can present a special hazard when a line or seal is
punctured resulting in the spraying of chemical many yards away. If a chemical spill occurs, consult
the Material Safety Data Sheet (MSDS) for specific instructions regardings the chemical being used.
IV. Installation
A. Location
The standard Model R is prewired for easy installation. Select a secure mounting location convenient
to electrical and plumbing connections that is accessible by the operator. Do not install the pump in a
location where the ambient temperature exceeds 120°F (50°C). The pump is suitable for most outdoor
installations, shielding from direct exposure to the elements is recommended. The properties of
solutions to be metered should also be considered concerning temperature changes and effects to poly
tubing. Accessory item R00225 (plastic mounting bracket) is recommend for a secure installation.
B. Electrode Installation
The standard Model R is provided with a TE-4A quick disconnect probe and T assembly on an 8’
lead. The tee has ¾ “ female slip connections. The probe must be installed in a sample line having
an inlet pressure higher than the outlet and 3-10 gpm flow for proper operation. Isolation valves on
both sides of the probe assembly are needed to allow for easy removal of the probe for cleaning.
See page 19 for probe and optional flow switch assembly diagrams.
NOTE: We recommend using schedule 80 pvc piping for the entrie sample stream assembly.
Using metal piping (copper, steel, etc), may cause electrical interference with the
conductivity sensor.
Chemical injection must be down stream from the probe!
