Operation and maintenance, Discfilter HPF2200-series PFLC
5. START UP AND OPERATION
5.1 Check procedures during start-up
1. Check that the drive unit cover is installed correctly.
2. Set the mode selector to the HAND position (see F in Figure 5.2).
3. Set the main power switch to the ON (1) position (see I in Figure 5.2).
4. Start the drum rotation on the operator pa-
nel main menu (see Figure 5.1 and Figure 5.2).
5. Open the water supply a little so that the
water can slowly run into the filter drum. Make
sure that the difference in water level between
the inside and outside of the filter drum does
not exceed 450 mm (see section 5.2.1). If the fil-
ter 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 unfiltered
water.
WARNING! A greater difference in water level between the inside and outside of the filter
drum than 450 mm will damage the filter.
6. When the water level inside the filter tank/chamber exceeds the suction pipe of the pump (or,
the suction pipe if a CR- pump has been installed), the pump must be started by pressing “Start”
on the operator panel main menu (see Figure 5.1). NB Also read section 2.7.
WARNING! The backwash pump must not be started until the water level has reached the
suction pipe of the pump (or, the suction pipe connected to the pump if using a CR- pump),
otherwise the pump will run dry and fail.
7. If the water level inside the filter tank/chamber reaches the overflow wall, turn the mode se-
lector from HAND position to either REMOTE or AUTO (see section 5.2).
8. Open the water supply fully.
If the filter is operated using automatic level control, it may be necessary to calibrate the level
sensor in order for the filter to be run optimally (see “Automatic System Manual HPF2200”).
