Maintenance schedule

Performance
When this indicator lamp lights up, solve the problems according to instruc-
tions in the "Troubleshooting" section
Check above-ground container for leakage.
Press the illuminated key "acknowledge message", find the cause for the
fresh water use and alleviate it.
Clean the dirt collection basket in the floor.
Check inlets and outlets of the plant for clogging.
Check recycled water for odour and turbidity. See section on "troubleshoot-
ing" for measures against poor quality of recycled water.
Check the detergent dose at the washing unit if there is too much foam for-
mation.
Perform backwash, then check the filter pressure.
(If the capacity is too low, initiate a manual backwash and inform the after-
sales service if necessary.)
Check circulation and membrane ventilator for proper function.
If the ventilation is running, bubbles are visible in the pump basin.
Check the status of the float sensors; inform Customer Service, if required. Operator
After sludge has been collected, there should be no sludge in any of the ba-
sins. The sludge in the sludge collector should be maximum 1 m in height.
Check sludge level; pump out and dispose of the sludge, if required. Clean
the basin.
Empty and clean the recycled water tanks.
Clean float switch, submersible pump and membrane ventilator.
Determine additional amount of water per vehicle washed.
DANGER
Health hazard due to dust and microbial pollutants. Wear face masks and
gloves while changing the gravel.
Replace gravel if necessary; while doing so, clean upper and lower filter
sieve (rinse off with water).
Does enough water flow from the pipe to the sludge trap during backwash-
ing? Check pressure.
The flow rate is correct if the water level in the processed water tank does
not fall below level S9 at the bottom when the washing unit is being operat-
ed.
Empty, clean, and refill.
