Note
Read the instruction manual carefully before use.
Note
If you wish to view specific information in detail, see the online
version of this manual.
2 Safety
2.1 Intended use
The pumps are intended for use with Struers cooling systems for recirculation of
cooling fluid. The machine is designed for use with Struers cooling systems.
The machine is for use in a professional working environment (e.g. a
materialographic laboratory).The machine must be operated only by
skilled/trained personnel.
Do not use the machine for the
following
Pumping of any type of explosive
and/or flammable material, or
materials which are not stable during
machining, heating or pressure.
Furthermore, the machine must not be
used with consumables (cutting fluids)
that are not compliant with function
and materials of the pump.
Model Cooling unit pumps
2.2 Device description
The pump is a machine used for recirculation of cooling fluid.
The pump is controlled via a Cooli-1 control box, which activates and stops the
pump. This means that it starts and stops based on the power output from the
Cooli-1 control box, and is on stand-by when circulation is not required.

If the Emergency stop is activated on the main machine, the Cooli-1 pump
also stops.
2.3 Cooling unit pumpssafety precautions
2.3.1 Read carefully before use
1. Ignoring this information and mishandling of the equipment can lead to
severe bodily injuries and material damage.
2. The machine must be installed in compliance with local safety
regulations. All functions on the machine and any connected equipment
must be in working order.
3. The operator must read the safety precautions and Instruction Manual, as
well as relevant sections of the manuals for any connected equipment
and accessories.
4. Only use original Struers consumables as this ensures maximum safety
and prolongs the machine's lifetime.
5. When working with cooling fluid always observe the safety regulations for
handling, mixing, filling, emptying and disposing of the cooling fluid
additive. Never use flammable cooling fluid. Note that the cooling fluid
can be hot and must therefore be handled with care.
6. Always wear protective gloves and safety goggles when you clean and fill
up the tank.
7. The recirculation pump must be disconnected from the electrical power
supply before it can be removed from the cooling unit.
8. All safety functions must be intact and in working order. If they are not,
they must be replaced or repaired before the machine can be used.
9. Always use the handle to close the cover.
10. Do not insert your hands through the openings into the water inlet ducts
on the cover.
11. Cooling fluid can be slippery - therefore always keep the area around the
tank clean.
12. If you observe malfunctions or hear unusual noises, switch off the
machine and call technical service.
13. In case of fire, alert bystanders and the fire brigade. Disconnect the
electrical power supply. Use a powder fire extinguisher. Do not use water.
14. Always switch off the electrical power supply and remove the plug or
power cable before dismantling the machine or installing additional
components.

• A small pump: use the adapter ring to decrease the diameter of the
connection.
• A large pump: remove the adapter ring to increase the diameter of the
connection.
Magnetic filter
• Mount the magnetic filter in the hole. See the section "Assembling the cooling
unit" in the Cooli System Instruction Manual.
Water level gauge
• Mount the water level indicator in the hole. See the section "Assembling the
cooling unit" in the Cooli System Instruction Manual.
7 Maintenance and service
Proper maintenance is required to achieve the maximum up-time and operating
lifetime of the machine. Maintenance is important in ensuring continued safe
operation of your machine.

Technical questions and spare parts
If you have technical questions or when you order spare parts, state serial
number and voltage/frequency. The serial number and the voltage are stated
on the type plate of the machine.
7.1 General cleaning
To ensure a longer lifetime for your machine, Struers strongly recommends
regular cleaning.
Note
Disconnect the machine from the power supply before cleaning
it.
If the machine is not to be used for a longer period of time
• Clean the machine and all accessories thoroughly.
7.2 Service and repair
We recommend that a regular service check be carried out yearly or after
every 1500 hours of use.
When the machine is started up, the display shows information about total
operation time and the machines service information.
After 1500 hours of operation time, the display will show a message
reminding the user that a service check should be scheduled.
Note
Service must only be performed by a Struers engineer or a
qualified technician (electromechanical, electronic, mechanical,
pneumatic, etc.).
Contact Struers Service.
Service check
We offer a range of comprehensive maintenance plans to suit the
requirements of our customers. This range of services is called
ServiceGuard.
The maintenance plans include equipment inspection, replacement of wear
parts, adjustments/calibration for optimal operation, and a final functional test.

7.3 Disposal
Equipment marked with a WEEE symbol contains electrical
and electronic components and must not be disposed of as
general waste.
Contact your local authorities for information on the correct
method of disposal in accordance with national legislation.
For disposal of consumables and recirculation fluid, follow
local regulations.
Note
Dispose of swarf according to the current local safety regulations for
handling and disposal of swarf and cooling fluid additive.
Note
The cooling fluid contains additive and cutting swarf and may not be
disposed of into a main drain. Cooling fluid must be disposed of in
compliance with local safety regulations.
Depending on which metals are being cut, it is possible that the combination of the
metallic swarf (cutting debris) from metals with a large difference in electrode-
positivity (a large distance apart in the electrochemical series), could result in
exothermic reactions when ‘favorable’ conditions are present.
Always bear in mind which metals you cut and the amount of swarf the cutting
produces. Some combinations of metals can result in exothermic reactions if a
large amount of swarf is collected during cutting.
