1. Brief operating instructions
Even if you find these brief instructions initially sufficient please read the subsequent sections, especially
Section 4: "Safety devices and warning notes".
Check the Water circulation cooler and accessories during unpacking for any transport damage and if
necessary inform the carrier.
Assemble the unit according to Section 6 and add extra items as appropriate.
When setting up the unit there must be a spacing of at least 0,5 m between the grills and any object which
could interfere with ventilation.
With the pump connections open fill the bath up to the top mark on the level indication: in the case of
WK 230 up to about 20 mm below the bath cover plate. Check that the drain valve on the back wall is
closed.
Connection of the hoses to the pump connections:
Connect the connecting hose to the external device. Protect the tubes with hose clips against slipping off.
Use only tubes suitable for the liquid used and for the maximum operating pressure!
Check the supply voltage against the details on the label. Insert the mains plug.
Test the sense of rotation of the three-phase alternating current connection at WKL 7000 (W) and
WKL 10000 (W).
Check that the tube connections have been made according to Item 1.5 and that the unit has been filled
according to Item 1.4! Switch on the mains switch (I). The temperature indicator on the control panel shows
the current bath temperature.
Press the key , the operating temperature setpoint appears on the display.
Set the temperature with the keys or .
Enter the new value with the key .
The indication shows if the compressor is running, i.e. if the unit is being cooled down or not.
The pressure gauge shows the pump pressure at the outflow connection (outlet) of the unit. The pressure
can be adjusted with the bypass valve at the back of the unit (see 8.4). Not on WKL 230, WK 500, WK 502,
WKL 600, WKL 603, WKL 700 und WKL 703!
