2750 DryLoc pH/ORP Sensor Electronics
Mounting Position
Mounting Angle using GF Signet Fittings.
*
Avoid locations with air pockets and/or sediment (90° and 270°).
Wet-Tap electrodes, 2724, 2734, and 2774 series electrodes
• Vertical (0°) position optimum.
• DO NOT install within 30º of horizontal (Contact factory
for horizontal or inverted installation requirements).
2764 series electrodes MUST be mounted upright.
When mounting in a standard threaded
fi
tting, the electrode must
be mounted horizontal to 60 degrees below horizontal position only:
2.
Thread the in-line retaining nut onto
fi
tting to secure the electrode into place.
Chemical Compatibility Warning
•
The retaining nuts of pH and ORP sensors are not designed for prolonged contact
with aggressive substances.
•
Strong acids, caustic substances and solvents or their vapor may lead to failure of
the retaining nut, ejection of the sensor and loss of the process
fl
uid with possibly
serious consequences, such as damage to equipment and serious personal injury.
•
Retaining nuts that may have been in contact with such substances e.g. due to
leakage or spilling, must be replaced.
1.
Insert electrode into Signet installation
fi
tting.
Seat the electrode tabs into the alignment notches in the
fi
tting.
NOTE:
This procedure applies to systems using 2724-2726 and 2734-2736 electrodes.
If the 3719 pH/ORP Wet-Tap is used, refer to the 3719 manual for instructions.
