START-UP AND FIRST OPERATION
1. Make sure that water flood direction coincides with the arrows indicated on the equipment.
2. A backflow valve has to be installed if it is foreseen reflux in the filter in order to protect the
device from water hammer. STF is not responsible for any damages occurred on the
equipment, in case of water hammers or pressures superior to the maximum design
pressure.
3. Butterfly valves have to be placed in the filter inlet and outlet to drain off the pipe and carry out
the maintenance. (The outlet butterfly valve will depend on the equipment placement in the
installation).
4. Disconnect the equipment.
5. Turn the circuit breakers to ON.
6. The equipment is already adjusted to operate correctly, (0.8 m.c.a pressure differential; 8 hours
between safety backwashings).
7. The pipe has to be object-free. The filter rotation has to be started before there is water flow in
the pipe.
8. Backwash manually when filling in the installation, until the pipe is pressurized completely.
