Temperature And Uv Intensity; Sensor Installation - Pentair BIOSHIELD Installation And User Manual

SECTION 3: INSTALLATION
Temperature & UV Intensity Sensor
Installation
Purpose
To instruct the operator how to properly install the
Temperature and UV Intensity Sensors.
Frequency
Required with new installation or when servicing the
unit during general maintenance.
Parts and Required Equipment
• Flare-Nut Wrenches
• Thread Tape
• Personal Safety Equipment
General risk due to electricity.
General risk due to pressurized piping and UV
vessel.
General risk due to suspended load.
Procedure
1. Install the Temperature and UV Intensity Sensors
into their respective port locations as labeled on
the vessel using Thread Tape to properly seal the
sensor threads in the vessel. To avoid possible
sensor damage from cable twisting, DO NOT
connect the sensor cables to the power supply
until after they are installed into the vessel. Leave
the sensor cables coiled up close to the sensor
during the installation process to allow the cable
to rotate as the sensor is being screwed into the
vessel. If the cable becomes twisted during the
installation process, untwist it before proceeding.
2. Use a flare-nut wrench to carefully tighten the UV
sensor and temperature sensor. These components
are made of soft polytetrafluoroethylene (PTFE)
and can be easily damaged. Leave the sensor
cables coiled up close to the sensor during the
installation.
3. Once the sensors have been installed into the
vessel you can attach cables to their respective
connection points located on the bottom of the
Power Supply Enclosure.
WARNING: Sensor-cables should be isolated from
other
electrical
sensor-cables must also be separated
from UV lamp cables to minimize
electrical interference.
NOTE: The Temperature Sensor must be installed
in the vessel with its water tight connector
properly connected to its respective port
located on the power supply enclosure.
A Temperature Sensor Cable connection
interruption will automatically shut down the
system.
