Note: All diagrams are strictly for guideline purposes only. Always consult an expert before installing
the FPUDT600 into specialized systems.
The FPUDT600 should be serviced by qualified persons only.
4.1Mounting Location
Choose an area located near the chemical supply tank, chemical injection point and electrical supply.
Install the pump where it can be easily serviced.
!
Mount the pump to a secure surface or wall using the enclosed hardware. Wall mount to a solid surface
only. Mounting to drywall with anchors is not recommended.
!
Keep the outlet (discharge) tubing as short as possible. Longer tubing increases the back pressure at the
pump head.
!
Do not mount the pump directly over your chemical container. Chemical fumes may damage the unit.
Mount the pump off to the side or at a lower level than the chemical container.
!
Mounting the pump lower than the chemical container will gravity feed the chemical into the pump. This
“flooded suction” installation can reduce the time required to prime the pump. Install a shut-off valve,
pinch clamp or other means to halt the gravity feed to the pump during servicing.
!
Your solution tank should be sturdy. Keep the tank covered to reduce fumes.
!
Be sure your installation does not constitute a cross connection with the drinking water supply. Check
your local plumbing codes.

4.3How To Install the Tubing and Fittings
CAUTION: PROPER EYE AND SKIN PROTECTION MUST BE WORN
WHEN INSTALLING AND SERVICING THE FPUDT600
4.3.1Inlet Tubing - Locate the inlet fitting of the pump head, see fig 4.7. Remove the tube nut. Push the
clear PVC suction tubing onto the compression barb of the fitting. Use the tube nut to secure the tube.
Hand tighten only.
4.3.2Footvalve/Strainer -Trim the inlet end of the suction tubing so that the strainer will rest in a vertical
position, approximately one inch from the bottom of the solution tank. This will prevent sediment from
clogging the strainer. Loss of prime may occur if the footvalve is permitted to lay on the bottom of the
solution tank in a horizontal position. Slip the ceramic weight over the end of the suction tube. Press
the footvalve/strainer into the end of the tube. Secure the ceramic weight to the strainer. Drop the
strainer into the solution tank.
4.3.3Outlet Tubing - Locate the outlet fitting of the pump head, see fig 4.7. Remove the tube nut. Push the
rigid outlet (discharge) tubing onto the compression barb of the fitting. Use the tube nut to secure the
tube. Hand tighten only.
Trim the other end of the outlet tube leaving only enough slack to connect it to the Injection/Check valve
Fitting (FIG. 4.9). Increasing the length of the outlet tube increases the back pressure at the pump head,
particularly when pumping viscous fluids.
Keep the inlet and outlet tubes as short as possible.

4.3.4Injection/Check Valve Fitting Installation - The Injection/Check valve fitting is designed to install
directly into either 1/4” or ½” female pipe threads. This fitting will require periodic cleaning, especially
when injecting fluids that calcify such as sodium hypochlorite. These lime deposits and other build ups
can clog the fitting increasing the back pressure and interfering with the check valve operation. See
section 6.0.
Install the Injection/Check valve directly into the tee fitting. Do not install the fitting into a pipe stud
and then into the tee. The solution must inject directly into the flow stream.
Use Teflon thread sealing tape on the pipe threads. Push the opaque outlet (discharge) tubing onto the
compression barb of the Injection/Check valve fitting. Use the tube nut to secure the tube. Hand tighten
only.

5.0How To Operate The FPUDT600
5.1 Adjusting the Pump Output
The FPUDT600 flow rate can be adjusted within a range of approximately 10%-100% of maximum output (27:1
turndown ratio) by means of a mechanical, cam type mechanism. The mechanism adjusts the pump’s stroke length to 1 of
27 settings within the flow range. The pump’s output is affected by the pressure of the system , the amount of suction lift,
and the viscosity of the fluid being injected into the pump must be over-sized to allow for these factors. Sizing the pump
to allow adjustment within the midrange is preferred to maintain accuracy. Consult the factory for individual pump model
output curve data.
To adjust the pump output:
1. Make sure the pump is off before adjusting.
2. Loosen the wing nut.
3. Turn adjusting knob so the pointer is on the desired setting. Note: pump less chemical at first, then re-adjust.
4. While holding the knob, tighten the wing nut to keep the knob at the desired setting. Note: wing nut must be tight.

5.2Priming The Pump
Each pump is factory tested with water. The test water is sealed in the pump head keeping the valves wet to aid in
priming. If the valves have dried or priming is difficult due to back pressure, do the following:
1. Remove the opaque discharge tubing from the top valve fitting in the pumphead.
2. Remove the top and bottom valve fittings and immerse in water to wet the valves. Reinstall the fittings.
3. With the discharge tubing removed, start the pump. Stop the pump when the fluid enters the pumphead.
4. Attach the discharge tubing to the top valve fitting.
5. Be sure the footvalve/strainer is attached to the suction tubing and is installed in a vertical position.
If your installation is at high altitude, priming may be more difficult since the atmospheric pressure is decreased. When
the suction line is dry, the diaphragm may not create enough pull. If this is the case, do the following:
1. Remove the clear suction tube from the bottom valve fitting and fill completely with water.
2. While the pump is running, attach the tube (filled with water) to the bottom valve fitting.
3. When the fluid enters the pumphead, place the foot valve in the solution tank.
4. Be sure the footvalve/strainer is attached to the suction tubing and is installed in a vertical position.

5.3 Measuring the Pump’s Output - Volumetric Test.
This volumetric test will take into account individual installation factors such as line pressure, fluid
viscosity, suction lift, etc. This test is the most accurate for measuring the injector’s output in an individual installation.
1. Be sure the Injection Fitting and Footvalve/Strainer is clean and working properly.
2. With the injector installed under normal operating conditions, place the Footvalve/Strainer in a large
graduated cylinder.
3. Fill the graduated cylinder with the solution to be injected and run the injector until all air is removed
from the suction line and the solution enters the discharge tubing.
4. Refill the graduated cylinder, if necessary, and with the Footvalve completely submerged in the
solution, note the amount of solution in the graduated cylinder.
5. Run the injector for a measured amount of time and note the amount of fluid injected. A longer testing
time will produce more accurate results.
5.4 Timer Equipped Model
1.The pause control knob adjusts the cycle timer’s time on. The FPUDT600 standard cycle time is set at
one minute. (+-10%) Other cycle lengths are available.
2. To adjust the amount of time on,turn the pause control knob to the correct setting. ½ equals
approximately 30 seconds on. 3/4 equals approximately 45seconds on, etc.

6.0How to Maintain the FPUDT600
6.1Routine Inspection and Maintenance
The FPUDT600 requires very little maintenance. However, the pump and all accessories should be
checked regularly. This is especially important when pumping chemicals. Inspect all components for
signs of leaking, swelling, cracking, discoloration or corrosion. Replace worn or damaged components
immediately.
Cracking, crazing, discoloration and the like during the first week of operation are signs of severe
chemical attack. If this occurs, immediately remove the chemical from the pump. Determine which
parts are being attacked and replace them with parts that have been manufactured using more suitable
materials. The manufacturer does not assume responsibility for damage to the pump that has been
caused by chemical attack.
6.2How to Clean the FPUDT600
The FPUDT600 will require occasional cleaning, especially the Injection fitting, the Footvalve/Strainer,
and the pump head valves. The frequency will depend on the type and severity of service.
When changing the diaphragm, the pump head chamber should be wiped free of any dirt and debris.
]
Periodically clean the injection/check valve assembly. Dirt and other build ups can clog the fitting,
increase the back pressure and interfere with the check valve operation. See section 4.3.4. FIG. 4.9.
]
Periodically clean the suction strainer. FIG. 4.8.
]
Periodically inspect the air vents located on the back of the motor compartment. Clean if necessary.
