Pressure Relief Procedure

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever 

you see this symbol.

NOTE:

 The dispense gun is intended to be used with 

materials that are solid and at room temperature. The 

following procedure can only be performed when the 

system is hot.

1. Fully release gun trigger and engage gun trigger 

lock.

2. Shut off fluid supply pump.

3. Hold a metal part of the gun firmly to the side of a 

grounded metal waste container. Disengage the 

gun trigger lock, then trigger the gun. 

4. Fully release the gun trigger and engage the gun 

trigger lock. 

5. Open the pump drain valve. Triggering the gun to 

relieve pressure may not be sufficient. Have a 

container ready to catch drainage. 

6. If you suspect pressure has not been fully relieved 

due to the dispense gun being clogged:
a. VERY SLOWLY loosen the end coupling from 

the dispense gun to relieve pressure gradually.

b. Loosen the coupling completely.
c. Clear the obstruction in the dispense gun.

Trigger Lock

Always engage the trigger lock when you stop spraying 

to prevent the gun from being triggered accidentally by 

hand or if dropped or bumped. 

To engage the trigger lock, release the gun trigger and 

rotate the lock downward. 

To disengage the trigger lock, rotate the lock upward.

This equipment stays pressurized until pressure is 

manually relieved. To help prevent serious injury from 

hot pressurized fluid, such as skin injection or 

splashing fluid, follow the Pressure Relief Procedure 

when you stop spraying and before cleaning, 

checking, or servicing the equipment.
To help prevent serious injury from burns, do not 

touch hot fluid dispensing from the gun.
