OPERATIONAL AND MAINTENANCE INFORMATION
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 close the in-line
valve in the main supply line. Depending on
installation, knob may point up or down.
2. 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.
3. 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.
4. Clean the reservoir as needed and repeat
the steps to pump it out if needed. Close the
shutoff valve.
5. Remove the hose and clean the filter. See
previous page for procedure.
6. Refill the reservoir with nutrient solution.
7. Open the in-line valve and turn on the pump
to resume operation. Knob may point in
opposite direction depending on how valve was
installed.
