being pumped.
WARNING
HAZARDOUS FLUIDS
Improper handling of hazardous fluids or inhaling toxic vapors can cause extremely serious injury or
death from splashing in the eyes, ingestion, or bodily contamination. Observe all the following
precautions when you handle hazardous or potentially hazardous fluids.
D Know what fluid you are pumping and its specific hazards. Take precautions to avoid a toxic fluid
spill.
D Always wear appropriate clothing and equipment, such as eye protection and breathing appara-
tus, to protect yourself.
D Store hazardous fluid in an appropriate, approved container. Dispose of it according to all Local,
State, and Federal guidelines for hazardous fluids.
D Secure the fluid outlet hose tightly into the receiving container to prevent it from coming loose
and improperly draining the fluid.
D Pipe and dispose of the exhaust air safely, away from people, animals, and food handling areas.
If the diaphragm fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation on
page 5.
FIRE AND EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the pump and hose. If the equipment is not
properly grounded, sparking may occur. Sparks can ignite fumes from solvents and the fluid being
pumped, dust particles, and other flammable substances, whether you are pumping indoors or
outdoors, and can cause a fire or explosion and serious injury and property damage.
D To reduce the risk of static sparking, ground the pump and all other equipment used or located in
the work area. Check your local electrical code for detailed grounding instructions for your area
and type of equipment. See Grounding on page 4.
D If you experience any static sparking or even a slight shock while using this equipment, stop
pumping immediately. Check the entire system for proper grounding. Do not use the system
again until you have identified and corrected the problem.
D Pipe and dispose of the exhaust air safely, away from all sources of ignition. If the diaphragm
fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation on page 5.
D Do not smoke in the work area. Do not operate the equipment near a source of ignition or an
open flame, such as a pilot light.
United States Government safety standards have been adopted under the Occupational Safety and Health Act.
You should consult these standards—particularly the General Standards, Part 1910, and the Construction Standards, Part 1926.

Installation
Tightening Threaded Fasteners Before
First Use
Before using the pump for the first time, check and
retorque all external fasteners. See Torque Se-
quence, page 18. After the first day of operation,
retorque the fasteners. Although pump use varies, a
general guideline is to retorque fasteners every two
months.
Use a compatible thread sealant on all male threads.
Tighten all connections firmly to avoid air or fluid leaks.
CAUTION
To avoid pump damage, do not overtighten the
fittings to the pump.
Grounding
To reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of equipment.
Acetal Pump Grounding Instructions
For polypropylene and PVDF pumps, see the
warning above.
Ground all of this equipment.
Pump: Connect a ground wire (A) and clamp, Part No.
222011. See Fig. 1. The pump grounding locations
are on the manifold between the inlet and outlet ports.
Use the nut (B) and bolt (C) that are provided with the
pump, and install as follows:
1. Place the nut in the nut catcher on the underside
of the manifold.
2. Insert the bolt through the loop end of the ground
wire.
3. Insert the bolt through the hole on the pump manifold and tighten it into the nut that you positioned
in step 1.
4. Connect the clamp end of the ground wire to a
true earth ground.
WARNING
FIRE AND EXPLOSION HAZARD
This pump must be grounded. Before
you operate the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 3.
The acetal pump contains stainless steel fibers
which make the wetted parts conductive. Attaching
the ground wire to one of the grounding locations
grounds the wetted parts.
The polypropylene and PVDF pumps are not
conductive. When you pump conductive flammable fluids, always ground the entire fluid system
by making sure the fluid has an electrical path to a
true earth ground. See Fig. 1. Never use a polypropylene or PVDF pump with non-conductive
flammable fluids as specified by your local fire
protection code. Consult your fluid supplier to
determine the conductivity or resistivity of your
fluid.
US Code (NFPA 77 Static Electricity) recommends
a conductivity greater than 50 x 10
ter (mhos/meter) over your operating temperature
range to reduce the hazard of fire. Consult your
fluid supplier to determine the conductivity or
resistivity of your fluid. The resistivity must be less
than 2 x 1012 ohm-centimeters.

WARNING
TOXIC FLUID HAZARD
Read the USING HAZARDOUS FLUIDS
and FIRE AND EXPLOSION HAZARD
sections on page 3 before you operate
this pump.
Be sure the system is properly ventilated
for your type of installation. You must
vent the exhaust to a safe place, away
from people, animals or food handling
areas when pumping flammable or
hazardous fluids.
If the diaphragm ruptures, the fluid being pumped
is exhausted with the air. Place a container at the
end of the air exhaust line to catch fluid in case the
diaphragm ruptures, and disconnect the pump.
Mountings
.
ti10662a
Fig. 2
D Be sure the mounting can support the weight of the
pump, hoses, and accessories, as well as the
stress caused during operation.
CAUTION
The pump exhaust air may contain contaminants.
If needed, ventilate to a remote area to reduce
possible fluid contamination. See Air Exhaust
Ventilation on page 5.
D Mounting Bracket:
The pump is shipped with a 90 degree mounting
bracket (60). Mount the pump to the bracket using
the four screws (61) provided. Secure the opposite
portion of the mounting bracket to a horizontal
surface. The mounting bracket must be used for
proper pump performance.
D For all mountings, be sure the pump is secured with
screws and nuts.
WARNING
To reduce the risk of serious injury, splashing in
the eyes or on the skin, and toxic fluid spills,
never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the Pressure Relief Procedure on page
8 before you move or lift the pump.

Installation
Air Lines
WARNING
Bleed-Type Master Air Valve and Fluid Drain
Valve
A bleed-type master air valve and a fluid drain
valve are required on your system.
The bleed-type master air valve relieves air
trapped between itself and the pump. Trapped air
can cause the pump to cycle unexpectedly, which
could result in serious bodily injury, including
splashing in the eyes, injury from moving parts, or
contamination from hazardous fluids.
The fluid drain valve reduces the risk of serious
bodily injury, including splashing in the eyes or on
the skin, or contamination from hazardous fluids.
Install the fluid drain valve close to the pump’s
fluid outlet to relieve pressure in the hose if the
hose becomes plugged.
Fluid Lines
Fig. 3. On each end of the fluid manifold are a fluid IN
port and a fluid OUT port. NOTE: Make sure the fluid
OUT port on the fluid manifold is mounted up. This
will assure proper pump priming. Fluid-in and fluid-
out lines can be connected on the same end, or
opposite ends of the manifold. Plug ports that are not
used (plugs provided).
1. Mount the air line accessories on the wall or on a
bracket. Be sure the air line supplying the accessories is grounded.
a. The pump speed can be controlled in one of
two ways: To control it on the air side, install
an air regulator. To control it on the fluid side,
install a fluid valve near the outlet.
b. Install a bleed-type master air valve down-
stream from the air regulator, and use it to relieve trapped air. See the Bleed-Type Master
Air Valve and Fluid Drain Valve warning
above. Locate another bleed-type master air
valve upstream from all air line accessories,
and use it to isolate the accessories during
cleaning and repair.
c. The air line filter removes harmful dirt and
moisture from the compressed air supply.
2. Install a flexible air hose between the accessories
and the pump air inlet. Screw the air line fitting
into the air inlet.
