Pressure Relief Procedure
WARNING
HOT SURFACE AND FLUID HAZARD The material and equipment will be hot! To reduce risk of injury, wear eye
protection, gloves and protective clothing when installing, operating, or servicing this dispensing system.
SKIN INJECTION HAZARD
The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:
D are instructed to relieve the pressure D stop spraying/dispensing D install or clean the nozzle D check or service any of the system
equipment
This procedure describes how to relieve pressure from the automatic dispense valve. See your supply unit or system documentation for instructions on relieving pressure for the entire dispensing system. Use this procedure whenever you shut off the dispense valve and before checking or adjusting any part of the system, to reduce the risk of serious injury.
1. Shut off the material supply.
2. Shut off electrical power to the automatic dispense valve.
3. Close all self bleeding air supply valves for supply unit.
4. Have a container ready to catch the drainage, then bleed off material pressure by actuating the dis­pense valve.
5. Shut off air supply to valve.
NOTE: If you suspect that the nozzle or hose is
completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard,
retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Then clear the tip/nozzle or hose.
PRESSURIZED FLUID HAZARD
High pressures can cause serious per­sonal injury. Be sure to open the dis- pense valve during system heat-up to alleviate pressure which might occur in the system due to material expansion.
310538 11
Service
Prepare to Service Automatic Dispense Valve
If the unit is hot, determine whether or not you can service the unit after it has cooled down. Some mate­rials, like polyurethanes, may cure permanently when cooled and exposed to air, preventing you from disas­sembling the dispense valve. If you are working with such a material, service the unit while the material is at a temperature where the material is soft enough to work with. If the material can be reheated at a later time, you can service the unit after it has cooled, reheating the material as necessary.
Perform this procedure before servicing the automatic dispense valve.
1. Relieve the system pressure.
WARNING
To reduce the risk of serious injury, whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure (page 11).
2. Make sure material flow has been shut off.
3. Make sure system air has been shut off.
4. Remove power from the automatic dispense valve.
WARNING
HOT SURFACE AND FLUID HAZARD The material and equipment will be hot! To reduce risk of injury, wear eye
protection, gloves and protective clothing when servicing this dispensing system component.
5. If the material in the dispense valve can be re­heated, wait for the dispense valve to cool thor­oughly before servicing it.
If the material in the dispense valve cures perma­nently when cooled and/or exposed to air, service the unit while the material is at a temperature where the material is soft enough to work with.
