Pump Failure! 

 

 

 
 
 

 

Following a pump test failure, the instrument will shut itself off. 

In the event of a pump failure, perform the following steps: 

1.  Remove the probe assembly from the instrument and turn 

the Cannonball3 back on.  If the pump test passes, 
proceed to step 2a below.  If the pump test fails, proceed 
to step 2b below. 

2a  If the pump test passes, then the leak is in the probe 

assembly.  Inspect the probe assembly and look for leaks.  
Replace filters or probe part as necessary. 

 

Figure 6.2.3  Pump/tubing assembly diagram

  

2b  If the pump test fails, then the leak is inside the 

instrument.  If the leak is inside proceed to step 3. 

3.  Verify that the pump itself is correctly installed with the 

gasket seated correctly around the base of the pump.  
Retest.  If the test fails proceed to step 4. 

4.  Remove the retention screw on the replaceable internal 

filter assembly and check the filters.  Replace them as 
needed and reinstall the assembly.  Retest.  If the test fails 
proceed to step 5. 

5.  Open up the instrument and check that all hoses are 

correctly attached (see the hose diagram below)  Retest.  
If the pump test fails again, either replace the pump 
entirely, or return the instrument to Sperian 
Instrumentation. 

6.2.4. 

Can’t resume normal operation after a “Low Flow” 

shut down 

Possible causes: 

1.  Sample probe or internal pump filters need replacement. 

2.  Sample hose is kinked. 

3.  Sample probe and probe assembly contains fluids. 

Solution(s): 

Turn off Cannonball3, remove pump, disconnect sample probe 
an hose assembly, allow any trapped fluids to drain; replace 
filters as necessary, examine hose to make sure there are no 
kinks blocking normal flow. 

If these measures fail to resolve the problem, the pump itself 
may be the cause.  In this case, the pump assembly should be 
removed from the Cannonball3 and returned to Sperian 
Instrumentation. 

6.3  Sample probe assembly

 

The sample probe handle contains moisture barrier and 
particulate filters designed to remove contaminants that might 
otherwise harm the instrument.

 

CAUTION:  Never operate the Cannonball3 without the 
sample probe and hose assembly.  The sample probe 
handle contains replaceable filters designed to block 
moisture and remove particulate contaminants.  If the 
pump is operated without the probe assembly in place 
particulate contaminants may cause damage to the pump, 
sensors and internal components of the Cannonball3. 

Particulate contaminants are removed by means of a cellulose 
filter.  The hydrophobic filter includes a 0.1 

μ

m Teflon

™

 barrier 

which blocks the flow of moisture as well as any remaining 
particulate contaminants.
