Operation
Pressure Relief Procedure | Daily Shutdown |
Follow the Pressure Relief Procedure whenever you see this symbol.
This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.
This procedure describes how to relieve pressure from the dispense valve. See the supply system manual for instructions on relieving pressure from the entire sys- tem.
1.Shut off material supply pumps.
2.With the valve pointed into a grounded metal pail, use the lever (H) to open the inlet ball valves (J) and relieve the fluid pressure.
3.If the valve nozzle or fluid hose is clogged or if pres- sure has not been fully relieved after following the steps above:
a.Use lever (H) to close dispense valve inlet ball valves (J).
b.VERY SLOWLY loosen the static mixer nut (G) from the outlet manifold (F) or the hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or nozzle obstruction.
c.Use lever (H) to open dispense valve inlet ball valves (J).
NOTE: For brief shutdowns, leave the cured mixer in place until it is time to use a fresh mixer.
When you finish using the 2K Manual Dispense Valve, clean the outlet manifold (F) and protect it from drying or crystallization as follows:
1.Perform Pressure Relief Procedure, page 10.
2.Remove and properly dispose of the static mixer.
3.Dispense one shot of material into a waste con- tainer to clear any crossover in the outlet manifold (F).
4.Wipe the nose with a clean rag, being careful not to let the materials contact each other.
5.Install PTFE night capt (19) and retaining nut (G).
Flushing
Flush the valve regularly to remove material build up.
1.Perform Pressure Relief Procedure, page 10.
2.Remove static mixer.
3.To maintain ground continuity, press and hold a metal part of the dispense valve against the side of a grounded metal pail then pump solvent through the gun into the grounded metal pail until clean sol- vent is dispensed. Use the lowest pressure possible while dispensing solvent.
