1. Description
The cooling unit OW 4002 is intended for the cooling of an oil circuit. Oil circulates between
the cooling unit and the heat source. The oil is re-cooled by a water-cooled heat exchanger.
Cooling hoses are connected to the cooling unit via screw and via hose nipples.
Coolant inlet and outlet are marked with symbols: Inlet:
O
↓
, outlet
O
↑
The oil flow is monitored by an adjustable flow switch, the oil temperature by an adjustable
thermal switch. The signals of the flow switch and the thermal switch are available at a po-
tential free safety circuit. The oil pressure is limited by an adjustable bypass valve.
The capacity of the cooling unit depends on the temperature difference between the cooling
water temperature and the oil outlet temperature.

3. Setting to work
Remove cover
Remove cap of oil reservoir and fill with oil up to the visible mark
Connect oil hoses to cooler.
Connect water supply to cooler.
Establish electrical connections according wiring diagram, use suitable leads.
Start water supply to cooler.
Start power supply for cooler
Exhaust valve open
Run oil cooler for approximately 10 minutes to
remove air from the oil circuit.
Exhaust valve close
Check oil level and refill if necessary
Stop cooling unit
Close cap of oil reservoir.
Mount cover.
Cooling unit is ready for use.
4. Maintenance
Check oil level at inspection glass monthly or more often, if necessary and refill oil.
5. Putting out of operation.
- Stop oil circulation by switching off pump.
- Disconnect equipment from mains.
- Lock oil supply and return pipes.
- Lock cooling water supply and return pipes.
- Drain water off the cooling system for frost.
