Electrode Installation - Advantage Controls MicroTron Manual

Electrode Installation

MicroTron tower controllers may come configured for various recirculating water systems. Listed below
are instructions for typical cooling tower installations. Your specific installation requirements may differ but
should conform to these instructions as much as possible for proper operation.
The standard probe(s) and/or flow assembly for cooling tower installations is constructed of schedule
80 PVC and supplied with ¾" slip fittings for installing into a sample line. To insure proper operation the
sample line must have a flow rate of 3-10 gpm. Inlet pressure must be higher than outlet pressure in order
for water to flow past the electrode(s) at the required rate. The probes are temperature compensated for
increased accuracy.
NOTES:
1. Install an isolation valve on either side of the flow assembly so electrodes can be
easily isolated for removal and cleaning.
2. A line strainer is recommended upstream from the probes to protect against fouling
and damage.
3. Mount pH electrodes vertically.
4. Units with a flow switch require the needed flow rate to operate the relay outputs.
5. Tap points for sample line should not be at the top or bottom of the supply piping to
reduce air or debris introduction to sample line.
WARNINGS:
1. Electrodes are O-ring sealed, which if damaged will cause a leak.
2. Do not allow pH sensor tips to dry out, damage will occur.
3. Do not exceed a water temperature range of 32°F to 140°F.
4. Do not exceed a maximum pressure of 150 psi.
