• Air and fluid hoses: Use only grounded hoses with a
maximum of 500 ft (150 m) combined hose length to
ensure grounding continuity.
• Air compressor: Follow the manufacturer’s recommendations.
• Fluid supply container: Follow the local code.
Mountings
1. Install the air line accessories as shown in FIG. 3.
Mount these accessories on the wall or on a
bracket. Be sure the air line supplying the accessories is grounded.
a. Install an air regulator (C) and gauge to control
the fluid pressure. The fluid outlet pressure will
be the same as the setting of the air regulator.
b. Locate one bleed-type master air valve (B)
close to the pump and use it to relieve trapped
air. Locate the other master air valve (E)
upstream from all air line accessories and use it
to isolate them during cleaning and repair.
c. The air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
2. Install a grounded, flexible air hose (A) between the
accessories and the 1/2 npt(f) pump air inlet (M).
Use a minimum 3/8 in. (9.5 mm) ID air hose. Screw
an air line quick disconnect coupler (D) onto the end
of the air hose (A), and screw the mating fitting into
the pump air inlet snugly.
CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. See Air Exhaust Ventilation
on page 8.
• Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
• For ease of operation and service, mount the pump
so the air valve cover (2), air inlet, and fluid inlet and
outlet ports are easily accessible.
Air Line
A bleed-type master air valve (B) is required in the
system to relieve air trapped between this valve and
the pump. Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury
including splashing in the eyes or on the skin, injury
from moving parts, or contamination from hazardous
fluids. See F
IG. 3.
Do not connect the coupler (D) to the fitting until you
are ready to operate the pump. Connecting the coupler too early can result in unintentional operation of
the pump, leading to serious injury from to moving
parts, splashing fluid in the eyes or on the skin, and
contact with hazardous fluids.
Fluid Suction Line
1. Use flexible, grounded fluid hoses (G) where possible.
2. For best sealing results, use a standard Tri-Clamp®
style sanitary gasket of a flexible material such as
EPDM, Buna-N, fluoroelastomer, or silicon.
3. If the fluid inlet pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in inefficient pump operation.
6 310622L
Installation
4. At inlet fluid pressures greater than 15 psi (0.1 MPa,
1 bar), diaphragm life will be shortened.
Fluid Outlet Line
A fluid drain valve (J) is required to relieve pressure in
the hose if it is plugged. The drain valve reduces the risk
of serious injury, including splashing in the eyes or on
the skin, or contamination from hazardous fluids when
relieving pressure. Install the valve close to the pump
fluid outlet. See F
IG. 3.

Air Exhaust Ventilation
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, food handling
areas, and all sources of ignition when pumping flammable or hazardous fluids.
Diaphragm failure can cause the fluid being pumped
to exhaust with the air. Place an appropriate container at the end of the air exhaust line to catch the
fluid. See F
The air exhaust port is 3/4 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
To provide a remote exhaust:
1. Remove the muffler (P) from the pump air exhaust
port. See F
IG. 5.

2. Install a grounded air exhaust hose (T) and connect
the muffler (P) to the other end of the hose. The
minimum size for the air exhaust hose is 3/4 in. (19
mm) ID. If a hose longer than 15 ft (4.57 m) is
required, use a larger diameter hose. Avoid sharp
bends or kinks in the hose.
3. Place a grounded container (U) at the end of the air
exhaust line to catch fluid in case of a diaphragm
rupture. See F

Operation
Operation
Pressure Relief Procedure
1. Shut off the air to the pump.
2. Open any available outbound fluid valve to relieve
fluid pressure from the pump.
3. If fluid is still in the outbound fluid lines, isolate this
fluid as follows:
a. Close the outbound fluid valves.
b. Slowly remove the fluid connections from the
pump, and have a container ready to catch any
fluid that runs out.
Sanitizing the Pump Before First Use
The pump was built and tested using a food grade
lubricant.
It is the user’s responsibility to properly sanitize the
pump before first use. It is up to the user whether this
will include disassembling and cleaning individual parts
or simply flushing pump with a sanitizing solution. As
necessary, follow the steps under Starting and Adjust-
ing the Pump below, under Flushing on page 11, or
under Disassembly in the Service section on pages
19, 21.
2. Check connections to be sure they are tight. Tighten
fluid inlet and outlet connections securely.
3. Place the suction tube (if used) in fluid to be
pumped.
If fluid inlet pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in inefficient pump operation.
4. Place the end of fluid hose (L) into an appropriate
container.
5. Close the fluid drain valve (J).
6. Back out the air regulator (C) knob, and open all
bleed-type master air valves (B, E).
7. If the fluid hose has a dispensing device, hold it
open while continuing with the following step.
8. Slowly increase air pressure with the air regulator
(C) until the pump starts to cycle. Do not exceed the
maximum operating air pressure as listed in the
Technical Data section on pages 34 and 37. Allow
the pump to cycle slowly until all air is pushed out of
the lines and the pump is primed.
Pump Shutdown
At the end of the work shift, relieve pressure.
Starting and Adjusting the Pump
1. Be sure the pump is properly grounded. Refer to
Grounding on page 5.

Maintenance
Maintenance
Lubrication
The air valve is designed to operate unlubricated, however if lubrication is desired, every 500 hours of operation (or monthly) remove the hose from the pump air
inlet and add two drops of machine oil to the air inlet.
CAUTION
Do not over-lubricate the pump. Oil is exhausted
through the muffler and could contaminate your fluid
supply or other equipment. Excessive lubrication can
also cause the pump to malfunction.
Flushing
Insert suction tube into cleaning solution. Open air regulator to supply low pressure air to the pump. Run the
pump long enough to thoroughly clean the pump and
hoses. Close the air regulator. Remove the suction tube
from the cleaning solution and drain pump. Place suction tube in the fluid to be pumped.
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Flushing schedule will be based on what
the pump is being used for. Use a compatible cleaning
solution and always cycle the pump during the entire
flushing process.
Routine Cleaning of Product Contact
Section of Pump
The pump and the system should be cleaned in
accordance with your state sanitary standard
codes and local regulations.
1. Flush the system. See Flushing above.
2. Relieve pressure in the system. See Pressure
Relief Procedure on page 10.
3. Disassemble the fluid section of the pump and
accessories. See Check Valve Repair on page 19
and Diaphragm Repair on page 21.
4. Using a brush or other C.I.P. methods, wash all
product contact pump parts with an alkaline detergent at the manufacturer’s recommended temperature and concentration.
5. Rinse these parts again with water and allow parts
to completely dry.
6. Inspect the parts and reclean any soiled parts.
7. Immerse all product contact parts in an approved
sanitizer before assembly. Leave the parts in the
sanitizer, taking them out only one by one as
needed for assembly. See Check Valve Repair on
page 19 and Diaphragm Repair on page 21.
8. Lubricate the clamps, clamping surfaces, and gaskets with waterproof sanitary lubricant.
Always flush the pump and relieve the pressure before
storing it for any length of time.
9. Circulate the sanitizing solution through the pump
and the system prior to use. Cycle the pump as the
sanitizing solution is circulated.
Tightening Connections
Before each use, check all hoses for wear or damage,
and replace as necessary. Check to be sure all connections are tight and leak-free.
