VIII. Maintenance and Cleaning
1. To guarantee trouble-free use for many years it is necessary to clean the dispenser
regularly. If there is any sign of a potential malfunction (e.g. piston is difficult to move)
never use force. Immediate cleaning should be carried out.
2. Do not leave the dispenser empty without cleaning to avoid clogging the valve balls!
If this does happen soak the dispenser for some hours in cold water or clean it using
ultrasound. Once the piston can be moved, dismantle and remove any residual impurities
by cleaning with a normal solution.
Disassembly of the Dispenser:
a) Remove the intake tube.
b) Unscrew the discharge tube (caution- do not remove the thread nipple from the
valve block)

it by pulling it down
