Funnel 
20 Litres of clean distilled water (maximum amount required if reservoir empty) 

Procedure 

(Refer to Figure 8.3.1) 

1.  Switch off the KMW200CCD. 

2.  Disconnect the plug from the mains power supply. 

3.  Close the inlet and outlet valves. 

4.  Place a bucket beneath the water inlet valve. 

5.  Holding the filter cover unscrew the lower retaining nut. 

6.  Unscrew the filter cover whilst holding the upper retaining nut. 

7.  Remove the filter. 

8.  Clean the filter under clean running water. 

9.  Place the filter back in the filter cover. 

10.  Check the position of the washer is correct inside the nut. 

11.  Screw the filter cover into the upper retaining nut. 

12.  Screw on the lower retaining nut. 

13.  Open the outlet and inlet valves. 

14.  Re-connect the plug to the mains power supply. 

15.  Switch on the KMW200CCD. 

16.  In order to de-aerate the filter unscrew the filter cover momentarily and then re-tighten it. 

17.  Check for water leaks. If there are any leaks: remake the connection.
