6. Connect the pump motor to the electrical supply following the instructions in the pump manual.
7. To prevent any water leakage from the vessel, make sure the drain plug (13) is in place.
Note 1: Do not use force when connecting the union to the valve.
Note 2: Use Teflon tape for sealing the threads.
Note 3: If connecting the vessel to a d50 mm pipeline, use a suitable cleaning agent and glue for those
connections.
STARTING UP THE FILTRATION UNIT
IMPORTANT: ONLY CHANGE VALVE POSITIONS WITH THE PUMP SWITCHED OFF.
Before changing the position, wait about half a minute after switching off the pump for any churned up
impurities to settle.
1. Check the tightness of all connections and wash the filter sand.
2. Press the valve control lever down and turn it to the position BACKWASH. Always press the lever down
first and only then turn it; otherwise, the gasket may be damaged.
3. Fill the pump with water and start it. CAUTION: The inlet and outlet pipelines must be clear;
otherwise, there is a risk of material damage or serious injury! Switch it off once clear water starts
coming out of the waste pipeline. This initial rinsing will remove any dust particles and impurities from the
filter sand.
4. Turn the valve control lever to the position RINSE. Start the pump again for about 10-20 seconds to force
any impurities out of the valve interior.
5. Then switch off the pump, put the valve control lever in the position FILTER and switch on the pump
again. This position is used for normal water filtration.
6. Check the whole assembly to see whether there are any water leaks, and tighten the unions and bolts as
needed.
7. Note down the initial pressure shown by the pressure gauge on the valve when the filter is clear (this
value differs between swimming pools depending on the pump used and pipeline length and shape). After
some time, sand contamination will reduce the water flow rate and increase the pressure. If the pressure
has increased 70 kPa from the initial pressure, the filter sand needs to be washed (see above).
Note 1: Initial filtering of new swimming pool water will require more frequent washing of the filter sand, as
the water contains more impurities.
Note 2: Clean the filter screen and skimmer baskets periodically to ensure correct operation of the filtration
system.
Note 3: Installations containing heaters or cleaning systems with nozzles are very sensitive to hydraulic thrust
because they operate at high pressures. Their installation must include all measures to reduce the risk of
hydraulic thrust.
