To ensure optimum cooling performance, the specified direction of flow in the
water oil­cooler must be observed. The cooling­water inlet and outlet must not
be reversed.
The pressure of the cooling water must not exceed 8 bar.
If the gear unit is being withdrawn from service for a longer period and if there
is a danger of freezing, the cooling water must be drained off. Remove any
remaining water with compressed air.
Add­on pressure monitors must be connected as shown in item 5.5.2.
Be especially careful when blowing with compressed air.
Wear protective glasses!
Depending on the order specification and application, the flange pump may have been replaced with
a motor pump.
For operation and maintenance, always observe the operating instructions indicated in
the order­specific appendix.
For technical data, refer to the order­specific list of equipment.
5.10.4.1 Pump
The pumps used are suitable for the delivery of lubricants. The flow medium must not contain abrasive
components and must not chemically affect the materials of the pump. A precondition of a proper
functioning, high reliability and long service life of the pump is in particular a clean and lubrifying delivery
medium.
5.10.4.2 Water oil­cooler
Water oil­coolers are suitable for cooling oils. The cooling medium used is water.
For connecting dimensions, refer to the dimensioned drawing of the gear unit. The
required cooling water quantity and the max. permissible inlet temperature are given on
the data sheet and/or the list of equipment.
5.10.4.3 Filter
The filter protects downstream aggregates, measuring and control devices from contamination. The filter
comprises a housing with connections and a sieve. The medium flows through the housing where the dirt
particles flowing trough the pipe are retained.
Dirty filter elements must be cleaned or replaced.
5.11 Heating
At low temperatures it may be necessary to heat the gear oil before switching on the drive unit or even
during operation. In such cases the use of heating elements is possible. These heating elements convert
electrical energy into heat which is conducted to the surrounding oil. The heating elements are located in
protective tubes inside the housing, thus making it possible to replace them without draining off the oil.
Complete immersion of the heating elements in the oil bath must be guaranteed.
The heating elements can be controlled by a temperature monitor which emits a signal when maximum and
minimum temperatures are reached; the signal requires amplification.
