Grounding
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
Be sure to ground all this equipment:
Pump: Use a ground wire and clamp as shown in F
Fluid hoses: Use only electrically conductive hoses.
Air compressor: Follow manufacturer’s recommenda-
tions.
Fluid supply container: Follow the local code.
IG. 1.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the valve firmly to
the side of a grounded metal pail, then trigger the
gun/valve.
To ground the pump: remove the ground screw (Z) and
insert through the eye of the ring terminal at end of the
ground wire (Y). Fasten the ground screw back onto the
pump and tighten securely. Connect the other end of the
ground wire to a true earth ground. See Fig. To order a
ground wire clamp, order Part. No. 222011.

Installation
1. Install the pump on the drum cover so that the
pump’s fluid intake is 1/2 inch. (13 mm) off the bottom of the drum. (F
IG. 2)
2. On Models 204254 and 222087, screw the bung
adapter tightly into the drum cover’s bung hole,
adjust the position of the pump in the drum, and
tighten the bung adapter screw to hold the pump,
System Accessories
Refer to FIG. 2 for the following instructions.
Four accessories are required in your system: an air
shut-off valve/air bleed device, fluid drain valve,
thermal relief kit, and ground wire. These accessories
help reduce the risk of serious bodily injury, including
fluid injection, splashing in the yes or on the skin,
injury from moving parts if you are adjusting or repair
the pump, and explosion from static sparking.
• The air bleed device relieves air trapped between it
and air motor after the air supply is shut off.
Trapped air can cause the motor to cycle
unexpectedly, causing serious injury if you are
adjusting or repairing the pump. Use either a
bleed-type master air valve (A) or a
quick-disconnect coupler (M) and fitting (L). Install
them near the pump air inlet within easy reach from
the pump.
• The fluid drain (H) assists in relieve fluid pressure
in the displacement pump, hoses, and dispensing
valve. Triggering the valve to relieve pressure may
not be sufficient.
• The thermal relief kit (R) assists in relieving
pressure in the pump, hose, and dispensing valve
due to heat and expansion.
• The ground wire (F) reduces the risk of static
sparking.
NOTICE
Do not hang the air accessories directly on the air
inlet (E). The fittings are not strong enough to support
the accessories and may break. Provide a bracket on
which to mount the accessories.
1. Install a pump runaway valve (D) to shut off the air
to the pump if the pump accelerates beyond the
pre-adjusted setting. A pump that runs too fast can
be seriously damaged.
NOTICE
Never allow the pump to run dry of fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself, and it may get very
hot.
2. Install an air line lubricator (N) for automatic air
motor lubrication.
3. Install a bleed-type master air valve (A) to relieve air
trapped between the valve and the motor. As an
alternative, you can install an air line quick-disconnect coupler (M) and fitting (L) to serve as an
air-bleed device. See F
IG. 2.
4. Install a Thermal Relief Kit (K) on the dispensing
valve side of the pump.
5. Install the air regulator (C) to control pump speed
and pressure.
6. Install an air line filter (B) to remove harmful dirt and
contaminants from the compressed air supply.
Install another bleed-type master air valve (A) to isolate the accessories for servicing.
7. Install a drain valve (H) near the pump fluid outlet.
8. Install a suitable fluid hose (P) and dispensing valve
(J).
NOTE: Install the air line accessories in the order shown
in F
IG. 2.
306518ZAC 5
Operation
Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
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 spraying and before
cleaning, checking, or servicing the equipment.
1. Close the pump air regulator and bleed-type master
air valve (required in the system).
2. Hold a metal part of the dispensing valve firmly to a
grounded metal waste container and trigger the
valve to relieve the fluid pressure.
Start and Adjusting the Pump
5. If your pump accelerates quickly or is running too
fast, stop it immediately and check the fluid supply. If
the supply container is empty and air has been
pumped into the lines, prime the pump and lines
with fluid, or flush it and leave it filled with a compatible solvent. Be sure to eliminate all air from the fluid
lines.
NOTICE
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself, and it may get very
hot.
NOTE:
• The low-level cut-off valve accessory (K) closes
the pump fluid intake when the fluid level is low,
which prevents air from entering the system.
• A pump runaway valve (D) should be installed
on the air line to automatically shut off the pump
if it starts to run too fast.
6. Read and follow the instructions supplied with each
component in the system.
1. With the air regulator (C) closed, open the
bleed-type master air valves (A), or, if so equipped,
join the quick-disconnect coupler (M) to the male fitting (L).
2. Open the dispensing valve (J) into a grounded metal
waste container, making firm metal-to-metal contact
between the container and valve.
3. Open the pump air regulator (C) slowly, just until the
pump is running. When the pump is primed and all
air has been pushed out of the lines, close the dispensing valve.
NOTE: When the pump is, and with sufficient air supplied, the pump starts when the dispensing valve is
opened and shuts off when closed.
4. Adjust the air regulator until you get sufficient flow
from the dispensing valve. Always run the pump at
the lowest pressure necessary to get the desired
results. Do not exceed the maximum working pressure of any component in the system.
7. If the pump will be unattended for any period of
time, if there is an air supply interruption, or at the
end of the work shift, shut off the system and always
relieve the pressure. (See Pressure Relief Procedure)
