Operation
12 3A5311D
Shutdown and Care of the
System
1. Stop the pumps at the bottom of the stroke to pre
vent fluid from drying on the exposed displacement
rod and damaging the throat packings.
2. Set the ram director valve on the supply pump to the
down position. See Figure 7.
3. Follow the Pressure Relief Procedure on page 12.
4. Always flush the pumps before the fluid dries on the
displacement rods.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Lock the dispensing device of the equipment that is
being used with this supply system.
2. Turn off the main air supply and disconnect the
main air line from the air shut off valve (K) on the
machine.
3. Set the ram director valve to the down position. The
ram slowly drops.
4. Quickly move the ram director valve up and down to
bleed air from the ram cylinder.
5. Unlock the dispensing device.
6. Hold a metal part of the dispensing device firmly to
the side of a grounded container and trigger the
device to relieve pressure.
7. Lock the dispensing device.
NOTICE
Never leave water or water-based fluid in a carbon
steel pump overnight. If you are pumping
water-based fluid, flush with water first, then with a
rust inhibitor, such as mineral spirits. Relieve pres
sure, but leave rust inhibitor in the pump to protect
parts from corrosion.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid, and moving parts, follow the
Pressure Relief
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.
