The oil/air cooler may only be used in the locations marked in the type label of the oil/air
cooler and motor and pump. The element with the least favourable class is decisive.
The decision of assessment of the place of operation is subject to the user.
The start-up of the coolers is permissible by qualified personnel only.
•
It has to be made sure that oil supply and discharge are properly connected.
•
The connections as well as the cooling element and pump have to be tested for leakages after start-up.
•
The electric motor is to be connected such that the torsional direction marked on the oil/air cooler is observed
as described in
Electrical connection
.
•
The cooler has to be grounded separately in the place marked (equipotential bonding of cooler).
•
Inspect the oil motor for leakages.
!
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.
•
When the motor is running vibrations and unusual noise (frictional noise, squeaking, etc.) must not arise.
!
With vibrations inspect the screw connection of motor and pump.
If the damage has not been repaired, the oil/air cooler must not be operated any longer.
Please consult with KTR.
