WARNING
To reduce the risk of serious bodily injury, including
fluid injection, your system must include a drain
valve installed near the pump fluid outlet to help re-
lieve fluid pressure in the displacement pump and
hoses when shutting off the pump. See Fig 2.
Install a fluid drain valve (B) and a grounded dispense
hose (A) to the
npt fluid outlet on the displacement
pump. Connect a suction hose to the
npt pump fluid
intake. See Fig 2.
Grounding
Ground the pump and system as described on page 3.

WARNING
Do not overpressurize the system
To reduce the risk of overpressurizing the system,
which could result in serious bodily injury, including
fluid injection:
l
NEVER exceed the maximum working pressure
of the lowest rated accessory in your system (hy-
draulic input or fluid output), or the stated maxi-
mum working pressures of this pump.
l
Regulate the hydraulic input and fluid output
pressures, as appropriate, to maintain safe work-
ing pressures.
WARNING
How to relieve pressure
To reduce the risk of serious bodily injury whenever
you shut off the pump, check, service, clean or repair
any part of the system, always follow the Pressure Re-
lief Procedure on page 2.
Be sure you ALWAYS shut off the supply line shutoff
valve first, and then the return line shutoff valve.
This is to prevent overpressurizing the reciprocator or
its seals. When starting up the hydraulic system, open
the return line shutoff valve first.
CAUTION
Hydraulic Oil Working Temperature
The recommended hydraulic oil operating tempera-
ture is 80
F (27
C). The reciprocator
seals will wear faster and leakage may occur if the
pump is operated at higher oil temperatures.
If the hydraulic oil temperature approaches
F
C), check the hydraulic fluid supply cooling
system, filters, etc. and clean or repair as needed.
WARNING
Be sure the entire system and flushing pails are
properly grounded before flushing. Always use the
lowest possible pressure, and maintain firm
to-metal contact between the gun and pail to re-
duce the risk of static sparking and splashing.
MAINTAIN FIRM
METAL-TO-METAL
CONTACT BETWEEN
GUN AND GROUNDED
METAL PAIL
Before you start the pump,
check the hydraulic fluid
level, and add fluid as necessary to fill the lines.
Flush the pump before using it for the first time
to re-
move the light oil which was left in after factory test. Be
sure the solvent used is compatible with the fluid to be
sprayed and the wetted parts of the pump.
Fill the displacement pump wet-cup (121)
full with
Throat Seal Liquid or a compatible solvent, to pre-
vent fluid from drying on the displacement rod or damag-
ing the packings. See Fig 3.
Fig 3
Pump Startup
1. Turn on the hydraulic power supply.
2 . Open the return line shutoff valve first, and then open
the supply line valve.
3 . Slowly open the flow control valve.
4 . Use the lowest pressure needed to get good fluid
flow or atomization. Higher pressures increase tip
wear and pump wear.
In a direct supply system, the pump will start when the gun
or valve is opened, and stall when it is closed.
In a circulating system, the pump will operate continuous-
ly until the hydraulic power supply is turned off.
