pressure is necessary for timely start of cleaning.
CLEANING
• If the pump is equipped with a strainer, visually check whether the strainer is clogged and
contains a large amount of coarse dirt. Blockage can also be found under the state of pressure
on the gauge because it shows lower value than the initial pressure. If the strainer is clogged
with dirt, it must be removed, cleaned and flushed. Before cleaning the filter, always close all
the valves of the tank.
• If the pressure gauge shows a value of 8-10 psi, the filtration is clogged with dirt and it is
necessary to clean the filtration sand in the container using BACKWASH mode. Make it the
same way as outlined in the Commissioning paragraph. If after backwash the pressure on the
gauge doesn’t decrease and therefore the throughput sand will remain small, it is necessary to
replace the sand.
• Exchange and check filter sand.
• Check the sand at least once a year. It must always be loose, with no lumps, crusts, algae and
other contaminants
• Before replacing the sand always close all the tank valves. Loosen and remove the clamp
connecting the container with the valve. Drain the water from the tank by drain valve on the
bottom part. Empty the old sand. Clean the suction container and filter tube. Wash and rinse
the inside of the container and fill with new sand as described in the Assembly paragraph.
NOTE : Follow the recommended for sand grain size. Sand with higher granularity cannot
perform well the function of the filter. Conversely, a filter with lower granularity would be
washed away.
PREPARING FOR WINTER AND SHUTDOWN
WARNING: Never expose filtration to the frost!
• During long-term period, you first need to clean the sand very thoroughly using the BACKWASH
mode. Then, disconnect the hoses leading to the valve, except for the pump hose. Turn the
valve to the WINTER mode. Then, using the drain valve, drain all the water and clean the pre-
filter (if the pump is equipped with it). After draining the water, check the sand and replace it
if necessary or disinfect.
STORAGE
1. Empty swimming pool and disconnect the hose from the pool and the filtration unit.
2. Remove and clean the insert according to the procedure mentioned above.
3. Empty the filter housing and all parts dry.
4. For the new season, we recommend to use a new filter element. Prepare it.
5. All seals lightly grease to preserve their flexibility.
6. For storage, we encourage you to save and use the original packing carton.
7. Parts of the filter unit and store in a dry ventilated place.
SERVICE AND SPARE PARTS
• Have your device serviced by a qualified repair personnel using only identical replacement parts.
