Flushing
Flush before changing colors, at the end of the day, before storing, and before repairing the equipment.
Flush with a fluid that is compatible with the fluid you are pumping and with the wetted parts of your system. Check with your fluid manufacturer or supplier for rec- ommended flushing fluids and flushing frequency. Relieve the pressure after flushing.
Do not allow paint or solvent to sit in the system for extended periods. Fluid could dry in the regulator and cause leakage. If leakage occurs, relieve pressure, then disassemble and clean the regulator.
Cleaning and Repair
When changing fluids or colors, the regulator should be disassembled and cleaned. Regular cleaning and inspection of the internal parts is necessary to keep the fluid regulator working properly.
1.Relieve all air and fluid pressure in the system.
2.Remove the regulator from the system.
3.Disassemble the regulator (see the parts drawings on pages 14 through 19).
4.Clean and inspect all parts.
CAUTION
Be very careful when handling the carbide balls and seats. Damage will cause poor operation and leak- age.
5.Inspect the diaphragm, packings,
6.Lubricate packings,
