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 com-
pletely 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.
6.0 How to Maintain the C-1500N
6.1 Routine Inspection and Maintenance
The C-1500N 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.
6.2 How to Clean the C-1500N
The C-1500N 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 and pump head cover
should be wiped free of any dirt and debris.
] Periodically clean the injection/check valve assembly, especially when injecting
fluids that calcify such as sodium hypochlorite. These lime deposits 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. 4.8.
] Periodically clean the suction strainer. Fig.4.7
] Periodically inspect the air vents located under the motor compartment and under
the pump head. Clean if necessary.

Proper eye and skin protection must be worn
when installing and servicing the pump.
