). Store away the remaining
gasket(s).
• Insert strainer (

4. Setting up the instrument
Water filter
In addition to the filter sieve supplied (item
3
in
Fig. 6)
Leica recom-
mends installing a sediment filter between the water extraction outlet
and ST5020, to guarantee that the instrument is only operated with clean
water.
This sediment filter should have the following properties:
Filter fineness:
25 µm
Rate of flow:
approx. 10 l/min (with 5 wash stations)
Pressure constancy:
10 bar
Connection to the filter output: 1/2" external thread
This filter insert must be checked and cleaned regularly.
If the filter insert is very dirty it must be replaced.
