TROUBLESHOOTING
Pump Runs Continuously
If the pump runs without being activated, replace the main PCB.
Pump is Running Backwards
Check that the polarity of the wires from the main PCB to the
motor is correct.
Pump Runs Too Slowly
1. Check that the squeeze tube or pump cartridge is not
jammed.
2. Check the chemical uptake line for kinks.
3. Verify that the chemical uptake line is not forming a seal
against the side or bottom of the chemical drum (See:
INSTALLING SUPPLY LINES in INSTALLATION
section).
4. If the liquid being pumped is very viscous the pump may
labor in order to move it. Using a less viscous chemical,
pumping shorter distances, setting longer run times, and
assuring that the squeeze tube is in good condition will help
address this issue.
For 115 VAC and 230 VAC Versions:
1. Verify that the correct line power is installed and adequate
power is arriving to the unit.
2. Check for 6.0 volts DC or greater at the motor connection
wires with the motor disconnected and the pump prime
button activated. If this voltage is present, replace the
motor gearbox. If the problem persists after the motor
gearbox has been replaced, replace the power PCB. If the
voltage is absent replace the main PCB.
For D-cell Battery Power Version
1. Check for 6.0 volts DC or greater coming from the battery
holder. If voltage is absent replace the batteries. If voltage
is present, proceed with step 2.
2. Check for 4.5 volts DC or greater at the motor connection
wires with the motor disconnected and the pump prime
button activated. If this voltage is present replace the motor
gearbox. If the voltage is absent replace the main PCB.
Pump Will Not Run
1.
Check that the squeeze tube or pump cartridge is not
jammed.
2. Check the chemical uptake line for kinks.
3. Verify that the chemical uptake line is not forming a seal
against the side or bottom of the chemical drum (See:
INSTALLING SUPPLY LINES in INSTALLATION
section).
4. Check to see that the motor connection wires are properly
connected from the main PCB to the motor gearbox.
5. Press the Program button once to assure that you are in Run
Mode. If you are in Run Mode the colon should blink once
per second. You must be in Run Mode for programmed
events to occur.
6. Push the Prime button and try to prime the pump. If the
pump does prime, check that events are properly
programmed.
For 115 VAC and 230 VAC Versions
1. Verify that the power is connected.
2. Check for 6 to 11 volts in the wire harness from the power
PCB to the main PCB. If the voltage is absent replace the
power PCB.
3. Check for 6 volts DC or greater at the motor connection
wires with the motor disconnected and the pump prime
button activated. If this voltage is present, replace the
motor gearbox. If the voltage is absent, replace the main
PCB.
For D-cell Battery Power Version
1. Make sure that the batteries are properly aligned.
2. Make sure that the polarity of the wires running from
battery pack to the main PCB is correct.
3. Check for 4.5 volts DC or greater coming from the battery
holder. If voltage is absent, replace the batteries. If voltage
is present, proceed with step 2.
4. Check for 4.5 volts DC or greater at the motor connection
wires with the motor disconnected and the pump Prime
button activated. If this voltage is present, replace the
motor gearbox. If the voltage is absent, replace the main
PCB.
For a programmed event to occur, the event
must be programmed at least 1 minute in the
future. If you return to Run Mode after the
start of a programmed event, that event will
not occur until the next programmed interval.
Clock Resets to 12:00 AM and Events are
Erased When Unplugged or Power is Lost
Replace backup battery.
Pump Will Not Operate When Programmed
Interval Occurs
Check event programming. If setup is correct, and the prime
switch activates the pump, replace the main PCB.
Pump Will Not Pull Liquid from the Supply
Container
1. If there is too much vacuum created, the pump will not be
able to move the chemical. This is easily recognized when
the squeeze tubing collapses. If this happens:
a) Check that the squeeze tube or pump cartridge is not
jammed.
b) Check the chemical uptake lines for kinks.
c) Ensure that the chemical uptake line is not forming a
seal against the side or bottom of the chemical drum
(See INSTALLING SUPPLY LINES in
INSTALLATION section).
d) Using a less viscous chemical, pumping shorter
distances, setting longer run times and ensuring that
the squeeze tube is in good condition will help address
the issue.
