Blue-White A-100N FLEXFLO Peristaltic Pump - Manual (Page 21)

6.7 Mode 5 - Pulse input (Batch) - In this mode, when the total number
of accumulated pulses is equal to the programmed pulse input value (Hz) ,
the pump will run for the programmed on time.
Two values must be programmed:
1) ON-T = The amount of time the pump will run when accumulated pulses
is equal to the programmed pulse input value (Hz).
2) Hz maximum = The number of input pulses that will trigger the batch.
+ Set the pump for mode 5. Press the MODE button until MODE 5 is

7.0 How to Maintain the A-100NE
7.1 Routine Inspection and Maintenance
The A-100NE requires very little maintenance. However, the pump and all
accessories should be checked weekly. This is especially important when
pumping chemicals. Inspect all components for signs of leaking, swelling,
cracking, discoloration or corrosion. Replace worn or damaged compo-
nents 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.
7.2 How to Clean and Lubricate the A-100NE
The A-100NE will require occasional cleaning and lubricating. The amount
will depend on the severity of service.
]When changing the pump tube assembly, the pump head chamber, roller
assembly and pump head cover should be wiped free of any dirt and debris.
]The pump head cover bearing may require grease periodically. Apply a
small amount of grease (Aeroshell aviation grease #5 or equivalent) when
necessary.
]Although not necessary, 100% silicon lubrication may be used on the
roller assembly and tube assembly.
]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.
]Periodically clean the suction strainer.
]Periodically inspect the air vents located under the motor compartment
and on the rear panel. Clean if necessary.
7.3 500 Hour Service Warning Timer
The A-100NE is equipped with a tube life warning timer. After approxi-
mately 500 hours of accumulated running time, the SERVICE icon will light.
This is a reminder that the pump tube is nearing its minimum life expec-
tancy and should be replaced. Your actual tube life will depend on many
factors such as the chemical used, back pressure, temperature, viscosity,
and motor RPM.
CAUTION: Proper eye and skin protection must be
worn when installing and servicing the pump.
