Installation
Fluid Line Accessories
Install the following accessories in the positions shown
in Fig. 1, using adapters as necessary:
D
Install a fluid drain valve (L) in a tee near the
pump fluid outlet. The drain valve is required in your
system to relieve fluid pressure in the displacement
pump, hose and gun/valve (see the WARNING on
page 6). Install with the drain valve pointing down,
but so the handle points up when the valve is open.
D
A fluid regulator (M) controls fluid pressure to the
gun/valve, and dampens pressure surges.
D
A gun or dispense valve (N) dispenses the fluid.
The gun shown in Fig. 1 is a high pressure dispens-
ing gun for highly viscous fluids.
D
A gun/valve swivel (P) allows freer gun/valve
movement.
Air and Fluid Hoses
Be sure all air hoses (S) and fluid hoses (R) are prop-
erly sized and pressure-rated for your system. Use
only electrically conductive hoses. Fluid hoses must
have spring guards on both ends.
