Pressure Relief Procedure

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 and splashing
fluid, follow the Pressure Relief Procedure when
you stop dispensing and before cleaning, checking, or
servicing the equipment.
NOTE: Always discharge fluid into an approved con-
tainer or location.
1. Shut off all fluid and pneumatic lines (A, K, & P)
using the two fluid shutoff valves (H) and the pneu-
matic needle valve (B).
2. Slowly loosen the fluid lines to (K & P) at the pump
outlets (L & M) to bleed off any residual pressure.
3. Disconnect the fluid lines (K & P) from pump outlets
(L & M).
