1.5 Working with chemicals
2. Safety instructions
Non-observance of the safety instructions may have dangerous
consequences for the staff, the environment and the product and
may result in the loss of any claims for damages.
The operating software of control unit 382 does not contain any
safety-related functions.
Should you require further information, please contact Grundfos.
3. Receiving the product
3.1 Transporting the product
The temperature and humidity limits for device transport, which
are described in the section Technical data, are to be observed at
all times. The device shall not be exposed to strong impacts,
mechanical loads or vibrations. The device should be kept free of
corrosive or organic solvent vapours, nuclear radiation as well as
strong electromagnetic radiation.
Transport should be done in a packaging that protects the device
(original packaging or protective covering if possible). Before
transport, piping and flow cells have to be emptied, and sensors
removed and if necessary separately packed.
3.2 Scope of delivery
Immediately upon receipt, please check the received
consignment for completeness on the basis of the delivery note
and check for any possible damage incurred during shipping.
Please inform the delivering dispatcher and Grundfos
immediately in case of any damages in transit.
In case of incompleteness please contact your local sales partner
immediately!
3.3 Product updates, other
The manufacturer reserves the rights to implement, without prior
notice, technical developments and modifications in the light of
continuous product care.
4. Installing the product
4.1 Installation location
As the correct installation of the DID is an important prerequisite
for satisfactory operation the following checklist for the
installation can be used to ensure that all sources for potential
operational problems can be ruled out to the greatest possible
extent during the installation, allowing the DID to operate
properly.
• Easy accessibility (mounting, sampling, functional check,
demounting)
• Availability of sufficient space sensor, installation fitting,
control unit, etc.)
• No external interferences (i.e. no electric and electro-magnetic
interferences by leakage current, earth fault of pumps, electric
motors, high voltage currents, etc.)
• Best possible weather and splash water proof set-up
• The panel is to be protected from UV (direct sunlight) to avoid
premature aging of plastic components.
• Power supply for control unit (operational reliability, voltage,
power)
For environment limits of installed sensors please refer to the
sensor manual.
The DID is designed to operate with drinking water at pressures
up to 0.3 MPa (43 psi) and temperatures from 0 (non freezing) to
45 °C (32 to 113 °F). Enclosure class of CU 382 is IP65.
4.2 Installing of DID
All parts of the DID are mounted onto a flat panel (see section
7.3 Components ). The complete DID can be mounted quickly and
easily with spacer (min. 10 mm) onto a flat wall. The mounting
holes for bolts or screws have been pre-drilled and are indicated
in the dimensional drawings. For the correct dimensions and
space required for mounting please refer to the figure in section
12.4 Dimensions .
For DID versions with tank immersed sensors the control unit
CU382 is mounted directly on the wall. The drilling scheme is
shown in section 12.4_dimensions.
4.3 Installing of hydraulic system
Sample water inlet and outlet have to be mounted onto the DID,
which will require the following actions, in the order presented
below:
• Remove the two blind bolts used for transport from the inlet
threat and the outlet threat of the flow cell using a 10 mm
hexagon socket screw key (see Fig. 1 below).
• Mount the specific fitting onto the outlet
• Mount the customer inlet tube onto the 1/2" inlet fitting
Fig. 1 Outlet fitting
WARNING
Danger of personal injury due to contact with
chemicals!
Wear the stipulated personal protective
equipment (protective clothing, goggles,
respirator etc.) when handling chemicals!
Observe the chemical manufacturer's safety data
sheets (MSDS) and safety instructions of the
used chemicals!
WARNING
Electric shock
• Switch off the power supply before connecting the
power supply cable and relay contacts!
• Do not dismantle the device!
• Maintenance and repair must only be carried out
by qualified personnel!
WARNING
Toxic material
Because the DID can be installed in industrial and
waste water applications, one has to take care during
mounting and demounting of the system, as parts of
the device can be contaminated with dangerous
chemicals or pathogenic germs. All necessary
precautions should be taken to prevent endangering
of one’s health during work with the measuring
device.
WARNING
Electric shock
• Switch off the power supply before installing!
Enclosure class IP65 is only guaranteed if the
terminal cover is correctly sealed, if the front
panel of the terminal enclosure is closed and the
appropriate cable glands or dummy caps fitted
