Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure is
relieved manually. To help prevent serious injury
from injection, splashing, or moving parts, follow
the Pressure Relief Procedure when you stop
pumping and before you clean, check, or service
the equipment.
1. For enclosed pneumatic control:
a. Turn off pumps by moving pump speed
selector switch (C) to the off (middle) position.
b. Close the air supply valve (L) to the pumps.
c. If used, open all user-supplied system fluid
drain valves that are downstream of the
pumps.
d. Either raise the ram to the top
position and engage safety latch (see
Engaging Safety Latch, page 16) or lower all
the way down.
e. Turn both ram up pressure (G
) and ram down
pressure (J) regulators to
zero psi.
f. Cycle ram position selector (A) up and down
until gauge (G6) on pilot check valve reads
zero psi.
g. Close the control panel supply valve (K).
2. For electro-pneumatic control:
a. Stop evacuation activity.
b. If used, open all user-supplied system fluid
drain valves that are downstream of the
pump.
c. Either raise the ram to the top
position and engage safety latch (see
Engaging Safety Latch, page 16) or lower all
the way down.
d. Navigate to the
System Configuration screen, page 48.
Press the Shutdown/Depressurize icon.
When pressed, a depressurizing pop-up
screen appears. The user must acknowledge
this screen to proceed.
e. When the system has completed
depressurizing, a pop-up screen will appear
(will take up to 1 minute). The user must
acknowledge this screen to proceed. Close
the air supply valves (CE and CF).
Flush the Pump Before First Use
The pump was tested in water. If water could
contaminate the fluid you are pumping, flush the
pump thoroughly with a compatible solvent. See
pump manual for flushing instructions.
