DESCRIPTION SG1 Smart Bluetooth flush controller New technology design of hardware, professional properties, and high reliability make the SG1 the most efficient solution for the management of the SG filter. Main features PD based flushing cycle activation The controller monitors the pressure differential between the inlet and outlet by means of a PD sensor and triggers flushing cycles accordingly.

DESCRIPTION Main parts Manual flushing button Battery compartment PD sensor (underneath the battery compartment) Cable gland PD sensor control tube nuts Wiring Manual flushing button Aquative operator (solenoid) PD sensor Battery compartment or external power supply (5v DC) Option: Filtron 1-10 flush controller Optionally, SG filters can be supplied equipped with the Filtron 1-10 flush controller for additional control features.
DESCRIPTION Control tubes The PE 8 mm command tubes are factory-installed and do not require any intervention during installation of the filter. The control-tube connection scheme below is to be used as reference while troubleshooting the filter. Legend a. From the filter inlet pressure point to the pressure gauge 3-way valve.
INSTALLATION Pre-installation preparations Design Recommendations If a long pipeline fill time causes a temporary high flow and low pressure situation, it is recommended to install a pressure-sustaining valve (PSV) downstream from the filter. The PSV will ensure a controlled fill-up of the line. It is highly recommended to install isolation valves upstream and downstream from the filter for maintenance and troubleshooting purposes.
INSTALLATION Hydraulic installation ATTENTION The inlet pipe should be of a diameter equal to or larger than the filter inlet diameter. Never connect a the SG filter to an inlet pipe of a diameter smaller than the filter inlet diameter. Ensure the direction of flow is according to the arrows marked on the filter inlet and outlet.
INSTALLATION Bluetooth flush controller activation Insert batteries into the Bluetooth flush controller NOTE Always use a whole set of 4 new batteries. Never use new and old batteries together. 1. Open the flush controller box using a cross-head The controller should turn on automatically. screwdriver.

FOR MANUAL ACTIVATION: PRESS BUTTON FOR 5 SEC. INSTALLATION POWER SUPPLY: 6 VDC (4XC batteries) Download the SG filter application to your Smartphone SCAN QR CODE FOR MANUAL FLUSH, BYPASSING 1. Scan the QR code (also on the flush controller) or download it from the appropriate THE CONTROLLER: app store and install it.
INSTALLATION Power the flush controller by an external power supply If electricity is available at the filter location, the flush controller can be powered by an external 100-240v AC to 5v DC power supply (not supplied). 1. Open the flush controller box using a cross-head screwdriver.
8. Perform 2 additional consecutive manual flushing cycles to evacuate air from the system. 9. Monitor the upstream pressure during the flushing cycles, it should not drop below 2.0 bar (30 PSI). If this cannot be ensured, consult Netafim™. NOTE The filter flushes in two, separate consecutive flushing cycles with a few seconds pause between them (During the pause the filter does not flush).

4. Make sure the filter flushes in two, separate consecutive flushing cycles with a few seconds pause between them. In case a clear pause between the two flushing cycles is not noticeable, consult Netafim. At the end of the irrigation season 1.
MAINTENANCE Screen assembly cleaning Disassembly: 1. Unscrew nuts (A) with a 17mm wrench 2. Remove washers (B) 3. Remove Piston Cover Assembly (C) and gasket (D) 4. Pull out suction assembly (E) 5. Pull out screen assembly (F). 6. Flush screen assembly (F) with pressurized fresh water and remove dirt. If the screen is still dirty, separate the flushing assembly from the screen assembly and flush screen assembly (F) from the inside out with pressurized water and remove remaining dirt.
MAINTENANCE Replacing the batteries in the Bluetooth flush controller The controller is powered by 4 x 1.5v C-size batteries (6v DC): NOTE Always replace the whole set of 4 batteries. Never use new and old batteries together. 1. Open the flush controller box using a cross-head 4.
