AESFill AF1C Machine Manual 48/58 Cleaning & Accessories
Exchanging Nozzles & Pumps 10.1
Cleaning a nozzle and pump is not difficult. However, many customers order extra
nozzles and pumps so they can quickly change over to a new product with a fresh
pump and nozzle while the other set is being cleaned.
The pump and nozzle can be removed from the machine all in one piece and taken to
the clean-up areas, then disassembled there.
If the product is very viscous or needs a solvent in order to effect cleaning, the solvent
can be run through the AESFill AF1 in order to begin the cleaning process. (Based on
compatibility with the elastomeric seals.)
