Clean the reservoir periodically to maximize plant growth and to minimize system contamination. The steps that follow can be used to change nutrient solution
and to pump the reservoir for cleaning and typical maintenance.
Cleaning the filter is strongly recommended after cleaning the reservoir.
RESERVOIR CLEANING AND MAINTENANCE
1. Turn off the nutrient pump and connect a
garden hose to the shutoff valve of the filter.
Place the end of the hose in a bucket or run it
to the desired location.
2. Open the shutoff valve on the filter and turn the
pump on to pump out the reservoir. Turn off the
pump once the reservoir is empty.
3. Clean reservoir. Repeat steps to pump it out if
needed.
4. Close the shutoff valve.
5. Remove the hose and clean the filter. See
previous page for filter cleaning procedure.
6. Refill the reservoir with nutrient solution. Turn
on the pump to resume operation. Check all
fittings, tubes, and filter for leaks.
