9.3. Intensive Cleaning
Intensive cleaning must preceded by the standard cleaning procedure
(see chapter 9.2). This procedure must be followed if the hand wheels
are hard to move, or if the instrument is heavily soiled. For this pur-
pose, the instrument must be partially disassembled.
Warning!
Before disassemble, always preform the standard cleaning proce-
dure. To prevent injuries from chemicals, always wear eye protec-
tion, protective clothing and protective gloves. Avoid splashing of
reagent.
1. Pull off the telescopic intake tube and clean it with a soft bottle
brush. Replace if necessary, especially if cracked or worn.
2. Clean discharge tube with a soft brush. Replace if necessary,
especially if cracked or worn.
3. For instructions about cleaning the discharge/recirculation valves,
see chap. 10.
Note:
The intake mechanism including the internal valves can only be
serviced by trained and authorized service personnel. If continues
to be soiled after repeated rinsing, please send the instrument to
your authorized dealer for repair (see Chapter 16.1).
