5. START UP AND OPERATION
5.1 Check procedures during start-up
1. Check that the drive unit cover is installed correctly.
2. Turn the pump switch to the OFF (0) position (see F in Figure 5.1).
3. Set the main power switch to the ON (1) position (see J in Figure 5.1).
4. Set the mode selector to the HAND position (see E in Figure 5.1).
5. Open the water supply partially so that water slowly flows into the filter drum. Make sure that
the difference in water level between the inside and outside of the filter drum does not exceed
550 mm (see section 5.2.1).
If the filter cloth becomes clogged, it may be necessary to fill the filter tank/chamber with water
from an external source or to remove a filter panel and fill the filter tank/chamber with unfilte-
red water.
WARNING! A difference in water level between the inside and outside of the filter drum
greater than 550 mm will damage the filter.
6. When the water level inside the filter tank/chamber reaches the pump suction pipe (or the
pump if a CRK or MTR pump is installed), the pump switch must be set to 1 (ON) position. NB Also
read section 2.7.
WARNING! The backwash pump must not be started until the water level has reached the
suction pipe (or pump if a CRK or MTR pump is installed), otherwise the pump will run dry
and fail.
7. When the water level inside the filter tank/chamber reaches the overflow wall, the mode se-
lector switch should be turned to AUTO mode.
8. Open the water supply fully. The filter is now run in the mode for automatic level control. It
may be necessary to adjust the level sensor so that the filter can be run optimally (see section
5.2.4).
