4.6 Pressure Relief Procedure
NOTE: The equipment stays pressurized until pressure is manually
released. To help prevent serious injury from pressurized fluid,
such as splashing fluid and moving parts, follow the “Pressure
Relief Procedure” when you stop dispensing and before cleaning,
checking, or servicing the equipment.
1. Push the STOP button.
2. Remove the applicator tip, and hold the applicator firmly against a
bucket.
3. Hold the pump direction switch in the REV position.
4. Allow the pump to run in reverse for several seconds while holding the
direction switch in the REV position.
NOTE: If the pump is stalled, do not run the pump for more than five
seconds at a time or the motor could encounter an overload error.
After multiple attempts to free the pump, allow the motor to cool for
one minute.
5. Push the STOP button after five seconds and release the pump
direction switch. The switch will return to its normal position.
6. Turn the main power disconnect switch to OFF.
7. Allow time for material to drain to relieve any remaining pressure.
8. If you suspect the applicator or hose is still clogged or that pressure
has not been fully relieved, proceed with the following steps:
a. Starting at the applicator, VERY SLOWLY open the coupling while
maintaining control of both the applicator and hose.
b. Clear the hose or tip obstruction. If there is still pressure trapped
down the line, work your way back to the pump by individually
opening each coupling between each hose connection. Maintain
control of each hose section and VERY SLOWLY open each coupling
until pressure has been fully relieved.
4.7 Flush
NOTE: Failure to flush prior to material curing in the system will
result in damage to the system and may require replacement of all
system parts in contact with material.
1. Remove the applicator tip and retainer.
2. Place the applicator outlet in a waste container.
3. Follow the steps below to flush material from the hopper and mixing
chamber:
