®
Run through a wash, making sure detergent level is full. If cells are still dirty, safely
removing cells and manual cleaning/spraying may be necessary. If air compressor
is available on site, spray out cells thoroughly of any dust and debris.
Safely remove cells and make sure they are installed correctly, ensure the cell
pushers are installed tightly with no slack in the cable. Cable could short out on
collector ionizer rods to the ground if installed incorrectly, see page 7.
IONIZER should be connected to the RED spark plug cable (Ionizer is the spiked
smaller plates that face the inlet of the unit) COLLECTOR should be connected to
the BLUE spark plug cable. GROUND cable should be connected to the BLACK
spark plug cable. Cells have been labeled by the laser to indicate each spark
plug connection.
If the unit dry portion of the wash cycle was bypassed, the cells may still be wet.
Run the fan for 60 – 90 minutes to dry out the cells.
Possible faulty or incorrectly programmed power supply. Contact factory for
further troubleshooting assistance.
Switch the leads on the LEDs located on the cover of the terminal enclosure(s).
Test voltage to LEDs and to input power of power supply when unit is on.
Replace LEDs/power supply if faulty.
Ensure spark plug style cables are properly connected, and that the cell pusher is
properly installed.
Check to see if there is a low detergent alarm, refill detergent if empty
Make sure detergent used is the recommended Zep X701
Increase wash sequence times
Make sure water temperature is 140°F and 40 psi
Fans need to be turned off before wash can be started
Check for fire micro-switch wiring (normally-closed contact between C1 and
NC1).
Confirm wash is running by referencing keypad/touchscreen. Check hot water
shut off valves feeding the unit.
Review wash history pages on controller, see page 17-18 for more details.
