Installation
Fluid Line Accessories
Install the following accessories in the positions shown
in Fig. 2, using adapters as necessary:
D
A fluid drain valve (N) is required in your system
to relieve fluid pressure in the hose and gun (see
the WARNING at left). Screw the drain valve into
the open branch of a tee mounted in the fluid line.
Install the drain valve pointing down, but so the
handle points up when opened.
D
A fluid regulator (P) controls fluid pressure to the
gun/valve, and dampens pressure surges.
D
A gun or valve (S) dispenses the fluid. The gun
shown in the Typical Installation is a dispensing gun
for highly viscous fluids.
D
A gun swivel (T) allows freer gun movement.
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 4.
1.
Pump: use a ground wire and clamp. See Fig. 1.
Loosen the grounding lug locknut (W) and washer
(X). Insert one end of a 1.5 mm
@
(12 ga) minimum
ground wire (Y) into the slot in lug (Z) and tighten
the locknut securely. Connect the other end of the
wire to a true earth ground. Order Part No. 237569

2.
Air and fluid hoses: use only electrically conductive
hoses.
3.
Air compressor: follow manufacturer’s recommen-
dations.
4.
Spray gun/dispense valve: ground through connec-
tion to a properly grounded fluid hose and pump.
5.
Fluid supply container: follow your local code.
6.
Object being sprayed: follow your local code.
7.
All solvent pails used when flushing: follow your
local code. Use only metal pails, which are con-
ductive, placed on a grounded surface. Do not
place the pail on a nonconductive surface, such as
paper or cardboard, which interrupts the grounding
continuity.
8.
To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
gun/valve firmly to the side of a grounded metal
pail, then trigger the gun/valve.
