sensors installed. Ensure that both the sensor connector and sensor port on the
cable are clean and dry and stay that way during this entire procedure.
3.
Install the conductivity/temperature sensor as follows:
a.
Locate the C/T port and, if replacing, remove the old sensor using the
installation tool to loosen the stainless steel retaining nut. Once the
stainless steel retaining nut has been completely unscrewed from the
bulkhead, remove the old sensor from the bulkhead by pulling the
sensor straight out of the bulkhead.
b.
Apply a thin coat of o-ring lubricant to the o-rings on the new sensor.
c.
Align the connectors of the new sensor and the port and push the sensor
in towards the bulkhead until you feel the sensor seat in its port. You
will experience some resistance as you push the sensor inward.
d.
Gently rotate the stainless steel sensor nut clockwise with your fingers,
Do not use the tool. The nut must be screwed in by hand. If the nut is
difficult to turn, STO P, as this may indicate cross threading. If you feel
resistance or cross threading at any point, unscrew the nut and try again
until you are able to screw the nut down completely without feeling any
resistance. Damage to your cable/sensor may occur if you force the
parts together.
e.
Once completely installed, the nut will seat flat against the bulkhead.
At this point, use the included tool to turn the nut an additional ¼ to ½
turn. DO NOT overtighten. Refer to the sensor installation sheet that is
included with the conductivity/temperature sensor for detailed
instructions.
4.
Install the 1001 pH sensor in port 1 as follows:
a.
If an old sensor is installed, remove it by twisting counter-clockwise.
b.
Apply a dab of grease to the new sensor o-rings.
c.
Unscrew the cap from the sensor storage bottle to relieve tension on the
o-ring and then remove the bottle. Replace the cap on the storage
bottle with the full cap that came with the new sensor to prevent
spilling the storage solution. Pat the sensor dry with a kim wipe.
d.
Push the sensor into the connector on the cable until it is properly
seated and only one o-ring is visible. Failure to properly seat the probe
may result in damage.
e.
Twist the sensor clockwise to engage threads and finger tighten. Do not
use a tool. This connection is waterproof. Refer to the sensor
installation sheet included with each sensor for detailed instructions.
5.
Install the 1004 ammonium sensor in port 2 as follows:
a.
If an old sensor is installed, remove it by twisting counter-clockwise.
b.
Apply a dab of grease to the new sensor o-rings.
