Myron L 729II - Manual (Page 15)

D. SENSOR INSTALLATION
The pH/ORP Sensor’s mounting orientation must provide a
continuous and adequate circulation flow to prevent the trapping
of air bubbles within the Sensor’s electrode area. Failure to do so
will result in conditions that will prevent the Sensor from
functioning properly.
1. INSERTION MODE (in-line installation)
Use one of the following as a guide. The Heavy Duty pH or ORP
sensor may be installed in any direction including inverted (sensor
UP). Substitute ORP sensor for pH where applicable.
Use approved sealant, i.e. Teflon tape as required.
1. Insert the Sensor Fitting assembly into the “T” fitting as
shown in one of the figures below.
2. Tightly secure.
2. IMMERSION OR DIP SENSOR ASSEMBLY
Use approved sealant, i.e. Teflon tape as required.
1. Insert and pull the Sensor’s cable through the extension
tube as shown in figure II.D.2.
2. Tightly attach extension tube to Sensor assembly as
shown in figure. II.D.2.
The sensor cable may be extended as necessary.
Additional cable may be ordered: Part Number pHCRD-(length)
Example: pHCRD-300(90m)
NOTE: 1000 ft/300 meter cable lengths have been tested with no
adverse affects on the readings. However, unusual conditions
may be experienced when extended long distances, i.e. power or
ground reversal. These conditions are beyond the control and
responsibility of the Myron L Company. A clean installation is
required. If you are experiencing errors, check the
Monitor/controller with a 10 ft/3 meter cable before contacting
your distributor or the Myron L Company.
