Figure 46: cleaning the filter
Note
The filter sponges must be wet before inserting, so that no air drawn from the
sponges into the system.
If there is no water flow into the filter or the pump does not promote water, please
turn off temperature controller switch, open both ball valves and drain some water to
carry out any air bubbles from the system. Then close the ball valves and turn on
temperature controller switch again. (Repeat above procedure if necessary.)
Fill the basin with water before inserting the filter
cartridge. The screen must be dry to prevent the for-
mation of air bubbles under the screen!
