With assembly, operation and maintenance of the oil/water cooler it has to be made sure
that the entire drive train is secured against accidental switch-on and the plant is
unpressurized. You may be seriously hurt by hot or pressurized hydraulic oil or water.
Please make absolutely sure to read through and observe the following safety indications.
•All operations on and with the oil/water cooler have to be performed taking into account "safety first".
•Please make sure to switch off the oil supply and water supply as well as the power pack before you perform
your work on the oil/water cooler.
•Secure the power pack, oil and water supply against accidental switch-on, e. g. by providing warning signs at
the place of switch-on or removing the fuse for current supply and lock the oil and water supply.
•Do not reach into the operation area of the machine as long as it is in operation.
•Secure the oil/water cooler against accidental contact (risk of burns). Please provide for the necessary
protection devices and covers.

You may only assemble, operate and maintain the oil/water cooler if you
•have carefully read through the operating/assembly instructions and understood them
•are technically qualified and specifically trained (e. g. safety, environment, logistics)
•are authorized by your company
The oil/water cooler may only be used in accordance with the technical data (see chapter 1). Unauthorized
modifications on the cooler are not admissible. We will not assume liability for any damage that may arise. In the
interest of further development we reserve the right for technical modifications.
The oil/water coolers PHE described in here correspond to the technical status at the time of printing of these
assembly/operating instructions.
The oil/water coolers are supplied in preserved condition and with painting and can be stored at a dry and roofed
place for 6 - 9 months.
!
The storage rooms must not include any ozone-generating devices like e. g. fluorescent
light sources, mercury-vapour lamps or electrical high-voltage appliances.
Humid storage rooms are not suitable.
Please make sure that condensation is not generated. The best relative air humidity is less
than 65 %.
!
In order to avoid any injuries and any kind of damage please always make use of proper
transport and lifting equipment.
The oil/water coolers are packed differently each depending on size, number and kind of transport. Unless
otherwise contractually agreed, packaging will follow the in-house packaging specifications of KTR.

Operating temperature -10 °C to +200 °C
Oil/water cooler (plate heat exchanger) made of stainless steel 1.4401 soldered with copper.
Please observe boiling and freezing point.
!
Please note that there may be sharp metal edges on the oil/water cooler due to
manufacturing.
Please wear safety gloves.

Please make sure that the lines are connected with zero potential. For that purpose refer to
table 2 for the torques required for the connection.

With assembly of the lines make sure that
•a liquid generally flows within one letter code only
•the liquids are positioned in the opposite direction, for example:
oOil to be cooled:
▪Inlet A1
▪Exit A2
oCooling water:
▪Inlet B2
▪Exit B1
oSide B is provided with one more drain on site which allows to fully
enclose the hot medium. The cooling capacity is fully used in this
way.
oSide A is intended for connecting the medium with the highest
temperature.
•Rinse the plate heat exchanger with the same liquid/medium as the
other system.
•Filter the liquid/the medium after rinsing.
Illustration 2: Connection of lines

Please make sure that the medium used does not show any dirt. In order to avoid any
blockages or damages on the oil/water cooler you have to make use of a filter.
A mesh size of filter of approx. 20 µm is usually sufficient.
!
Please note that the use of chlorous water, salt water etc. is not suitable for oil/water
coolers. Damages caused by corrosion cannot be excluded.

For fastening the oil/water cooler we
recommend to use a fastening retainer as
per illustration 3.
From size 200 two fastening retainers per
oil/water cooler are recommended.

The oil/water cooler can be used for various coolants:
•Coolant
•Water
•Oil
!
Please note that the use of chlorous water, salt water etc. is not suitable for oil/water
coolers. Damages caused by corrosion cannot be excluded.
Any generation of frost or ice will damage the oil/water cooler. Make use of a water-glycol compound if the
temperature is close to the freezing point or below. Please observe the operating temperature.
In respect of environmental protection we would ask you to dispose of the packaging or products on termination of
their service life in accordance with the legal regulations and standards that apply, respectively.
•Metal
Any metal components have to be cleaned and disposed of by scrap metal.
•Gaskets
Gaskets can be disposed of by residual waste.
•Nylon materials
Nylon materials have to be collected and disposed of by a waste disposal company.

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.
