Water Monitoring System
Ver.5.0.1 – Revision August 2022 Page 15 of 111
3 Safety Aspects
Before operating the system, read and understand the entire operating manual.
WARNING/ATTENTION
Follow the instructions.
• Please ensure correct connection of all power and signal cables before operating
the water monitoring system.
• The PAH sensor module and Turbidity sensor modules use UV and IR light. Please
do not stare into the lenses – it can cause damage to your eyes.
The pH/Temperature sensor uses an electrode which is
stored inside the system in a separate container to
maximize electrode lifetime. The electrode is delivered
with a safety cap on to ensure the electrode is kept moist.
The electrode will be damaged if it dries out. The cap must
be removed prior to start-up of the system. The
pH/temperature sensor is also fitted with a plug to prevent
moisture from entering the electrical connection. The plug
must be removed, and the electrode fitted prior to start-up.
• The suction line must not be blocked when the pump is running. The pump will be
damaged if the suction line is blocked.
• Do not run pump dry.
• Avoid air in the sampling system due to risk of air lock leading to flow alarm and
damage of the pump.
• Always ensure a positive suction pressure and keep discharge pressure as low as
possible in order to maximize pump lifetime.
• Pay attention to the temperature of the pump. Time to cool down can be needed
prior to attempting restart.
• Do not block the drain or outlet from a safety valve. Damage of components will
occur.
• Check the function of the safety valve to ensure correct operation. Follow the
planned maintenance program.
• The system is only suitable for installation in a safe, non-hazardous area and is not
suitable for use with flammable sample liquids. Non-wetted components such as
cabinet enclosure etc. must be kept dry and clean.
