Before cleaning please make sure that the oil/water cooler has cooled down.
Touching the heated components causes burns.
Rinsing allows to remove most of the soft deposits/dirt blocking the interior space. A solution used for rinsing
should be a soft acidity with a concentration of less than 5 %, e. g. phosphoric acid.
Rinse with 1.5 times the flow rate compared to regular operation, if possible, reverse the flow direction after 30
minutes.
Please note that the use of solutions being too acidic with rinsing is not suitable for
oil/water coolers. Damages caused by corrosion cannot be excluded.
Before you start-up the system again, rinse the oil/water cooler with fresh water.
Clean the oil/water cooler regularly.
Preventive maintenance operations have to be regularly performed by the user.
The maintenance intervals mainly depend on the operating period and the water speed reached. In case of
frequent standstill and low volume of water short maintenance intervals are necessary.
•
Inspect the oil/water cooler for leakages.
•
Proper fastening of the oil/water cooler has to be assured.
•
Inspect the oil/water cooler for damages.
!
Leakages have to be eliminated immediately.
Oil which has escaped has to be removed properly, since oil residues may vaporize on hot
components and ignite.
We recommend to store major spare parts on site to ensure the readiness for use of the machine in case if an
oil/water cooler fails.
Contact addresses of the KTR partners for spare parts and orders can be obtained from the KTR homepage at
www.ktr.com.
KTR does not assume any liability or warranty for the use of spare parts and accessories
which are not provided by KTR and for the damages which may incur as a result.
