Operation and maintenance, Discfilter HSF2600 - 2,3 series with PFLC
6. MAINTENANCE/SERVICE
This chapter describes how maintenance and servicing is to be carried out. Chapter 7 describes
how often the various components require servicing.
6.1 Filter cover
NOTE! Prior to servicing, read section 2.7. The filter cover for the Hydrotech Discfilter HSF2600
series is controlled from the operator panel and can be opened from two directions, depending
on which side of the filter needs to be accessed.
6.1.1 Hinge
Before the filter cover is operated from the operator panel, its hinge must be locked on the cor-
rect side. The locking pin (A) must lock the hinge lock (B) securely as shown in Figure 6.1a below.
Make sure that the filter cover is completely closed and that the hinge lock (B) shown in
Figure 6.1a surrounds the shaft (C) in Figure 6.1b.
The locking pin (A) and the hinge lock (B) must ALWAYS sit on the two outermost hinges (E), as
shown in Figure 6.2 or on the opposite side depending on which direction you want the cover to
open in.
In order to access the backwash pipe, the hinges must be locked (E in Figure 6.2) on the side of
the cover on which the drive unit (F) sits (see Figure 6.2), and the hinges must be open (see Figure
6.1b) on the opposite side, i.e. the backwash pipe side.

Figure 6.2 Shows the location of the lockable hinges and the drive unit.
