Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from starting or dispensing 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:

Sare instructed to relieve the pressure,

Sstop dispensing,

Scheck or service any of the system equipment,

Sor install a new or clean the dispense gun tip/nozzle.

1.Lock the gun trigger safety.

2.Shut off the air to the supply pumps.

3.Turn off the power (air) to the proportioning pump.

4.Unlock the spray gun trigger safety.

5.Hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun to relieve pressure.

6.Lock the trigger safety again.

7.If you suspect that the dispense valve or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Wear protective gloves to avoid skin injection or burns. Now clear the tip/nozzle or hose.

8.Be sure the fluid is cool before disconnecting the hoses.

Operation

WARNING

This equipment should not be used with more than one type of fluid due to poten- tial compatibility issues which could result in an unpredictable reaction.

Graco recommends using new hoses when chemicals are changed or care

must be taken to assure that all traces of one chemical are removed before introducing a second chemical.

CAUTION

SDo not pressurize hose until operating tempera- ture has been reached.

SOperate at lowest possible temperature and pressure necessary for application.

SHose must be vented during startup and shut- down.

SThe dispense valve must be kept open over a waste container while the system is heating up and also when cooling down. This will prevent a pressure build–up caused by fluids or gasses expanding from the heat.

Refer to your system operation manual for complete startup and operating instructions.

Maintenance

WARNING

SKIN INJECTION HAZARD

Do not mend or repair any part of a hose

assembly. If the hose is damaged, replace it immediately to avoid serious

injury from fluid injection and electric shock.

If the hose is not heating, be sure the connector at the hose control box is firmly plugged in. If that does not correct the problem, relieve the fluid pressure in the pump and hoses, as instructed at left. If the hose is faulty or the problem not corrected, replace the hose. See Troubleshooting on page 8 for electrical mea- surements.
