6 Care, Cleaning, and Maintenance
6.1 Cleaning
The diaphragm valves need to be cleaned if:
- idle periods of the dispensing system exceed seven days, and/or
- a different type of product is to be dispensed and/or
- valves are disassembled for replacement of spare parts.
Liquid residues may be removed with several solvents. Chlorinated hydrocarbons will obtain
optimum results; acetone would be the best alternative among non-CHC solvents.
If chemical products are not properly handled, damage to health can result.
• Observe general safety regulations for the handling of chemicals!
If the diaphragm valve is cleaned after prolonged idle periods or for a switch to a different
product, be sure to place new Loctite
®
product bottle into the tank. See operating manual of the
reservoir used.
For priming of the feed line, see operating manual of the controller used.
For setting of dispensing parameters, see operating manual of the controller used.
