READ ALL INSTRUCTIONS BEFORE OPERATING EQUIPMENT
TROUBLESHOOTING
Always wear appropriate personal protective equipment (PPE) when
troubleshooting unit.
Unit does not begin fill process
1. Check that the can / User-pack is placed firmly on top of the
whisker valve. If the can / User-pack is not holding the whisker
valve open the system will not run. If the valve has been bent
it may need to be straightened by bending it back into place so
that the can / User-pack can properly contact the whisker valve.
2. Check the door. The system will not run if the door is not
properly closed. There is a secondary air switch that needs to be
contacted for proper operation of the unit.
3. With the door closed, switch the filling station on. Undo the
thumb screws on the control box to access the regulators. The
gauge on the right should read 60 to 80 PSI (4.1 to 5.6 bar). If
no pressure is indicated, turn the system off and proceed to
No Pressure Detected, below. If the pressure is correct, skip to
Pressure Dectected.
No Pressure Detected
1. Adjust the regulator below the gauge on the right.
2. Check the Air In connections. Open the door and check the lines
running to the door switch and from the door switch to the
control box. This line is labeled "AIR IN" at the control box.
3. Check your compressed air system.
Pressure Detected
1. Check if the door switch can be depressed. It should move when
pressed and spring back to its resting position when released.
2. Make sure the door switch is fully depressed when the door is
in the closed position. If the bracket is bent the switch may not
contact the door and the bracket will have to be readjusted to
contact the door when the door is in the closed position.
3. With the system off, open the control box and verify that all
the tubes are correctly and securely connected. Also check the
air connection behind the whisker valve and the air connection
from the control box to the pump. Make sure air lines are not
kinked.
4. Verify that the LST14 level sensing tube is not plugged or
creased. The PSI on the level sensor regulator (located in the
control box) should be set to 0.5 to 2 PSI. If the regulator is set
too low the system will not dispense chemical.

Can / User-pack is not being filled completely
1. Check the height of the LST14 level sensing tube.
2. Check the chemical levels.
Can / User-pack is being over filled
1. Make sure the LST14 level sensing tube is inside the can / User-
pack. If it is outside the can / User-pack it will not detect the
level.
2. Check the height of the LST14 level sensing tube. It should be
about 1 in (2.5 cm) below the full line of the can / User-pack
when the fill tube is in the can / User-pack.
3. Check the left gauge inside the control box. It should be set to
0.5 to 2 PSI. If it is set above 2 PSI the system will not shut off
properly.
Air passes through the pump, but does not dispense
chemical
1. Verify that HV60 ball valve, located at the top of the suction
lance, is in the open position.
2. The pump must be replaced.
To change pump
Always wear appropriate personal protective equipment (PPE) when
changing pump. There may be chemical still in the system.
1. Rinse the system thoroughly with water to clear out remaining
chemical.
2. Turn system OFF.
3. Disconnect the red air line from the pump.
4. Disconnect the suction line from the pump.
5. Undo the 3 screws along the bottom edge of the black plate.
6. Carefully remove the plate by pulling the bottom edge out, then
pulling down.
7. Disconnect the chemical dispensing line from the pump.
8. Remove the 4 screws holding the pump to the plate.
9. Install replacement pump by following steps 3 to 8 in reverse.
