23、arameters cannot satisfy the user request, the user can act according to the actual operating mode to set various parameters, or selects ways such as hand control, automatic timing control to carry on the work correspondingly. When runs for the first time, please carry on according to the below st
24、ep: Inspects the filter whether to be at the normal work condition: Whether the pollution discharge tube has been connected, length of blowdown pipe can’t surpass 15 meters, cannot have the upward inclination angle, in order to avoid has the back pressure. Examine each joint whether reliable.
25、Examine that the electric cabinet is dry. Power-on, the green power light turn bright, indicated that electrical controlled part is at the normal work condition, the equipment can put into service Notes: maintain hands dry while inserts the electric power source. Meanwhile maintain electric contr
26、ol part is dry during the filter working, cannot let the water enter into. 9 Install and transport 9.1 Power connection Please choose power socket following the hints about voltage and power on the nameplate, select 1.5 mm2 or 2 mm2 wire and switch-in input terminal to the bottom of the electri
27、cal cabinet, as shown in picture 3. Please install the triphase power according to the picture 3. Picture 3 9.2 The connection about control box (1) Electrical motor connection: The electrical motor triple-phase line switch-in U3, V3, and W3 separately; the groundwire switch-in PE. As shown in

31、 water flow direction. The filtration needs to be installed by this direction. 2) Sewage pipe should be French connected onto the water solenoid valve. The pipe should not be longer than 15 meters and no angles allowed in order to avoid the pressure difference. 3) There are two ways of filter in
32、stallation. See Picture 5—7. Please note the water flow direction must be correct and the water solenoid valve should be installed at a horizontal level or at lower place in order to have a full cleaning. Picture 5 Picture 6 4) The
33、 filter should use a tandem combination. To guarantee uninterrupted water supply when overhauling the device for water treatment, We suggest you established the bypass in the system, the inlet and outlet of filter and the bypass should install the cut-off to use the valve, for example: The cut-off v
34、alve, the reed valve and so on. 5) The selection of filter specification should match to the pipeline installation. For example: The system caliber is 10, thus you may choose filter of specification 10. When the flow rate cannot satisfy the pipeline requests, users may use the way of parallel conne
35、ction, as shown in picture 7 Picture 7 6) The filter should install before the water equipment which system need to be protected, the installation should approach to the protected device as far as possible. 7) Install the check valve in the outlet of the filter in the
36、 place may cause backflow. 8) In the dynamic system, the filter should install between the pump and the equipment, more approaches the equipment to be better. If pressure between the pump and equipment surpasses filter's EP, should install the filter before the pump, and approach the pump as far a
37、s possible. 9) Installation of the electrical Controllers: When electric control leaving the plant, to be fixed according to default position. If the actual position is different from the default position, users can dismantle four erection bolts used fixed electric cabinet, after adjusting the elec
38、tric cabinet bracket and electric cabinet’s correct direction, and then fix the four erection bolts. 10) Choose the reasonable installation environment, pay attention to waterproofing, rainproof, and moisture-proof. 11) Before leaving the plant, the products have been debugged, user should not d
39、isassemble or debug at will. 10 Operation ST series has manual and automatic way of cleaning. The control panel is as follows in the picture 10. Picture 10 10.1 Manual Turn manual/auto to manual position. See picture 10. Motor and water control are connected to the power. The water valve
40、opens and it stars to clean. Turn the manual/auto to auto the system goes into automatic process. Manual control is a way to check whether the motor and water valve work properly. If the system can’t clean normally when it is under manual and it can’t do under auto. 10.2 Auto Turn to auto posi
41、tion. Set the filtration time and cleaning time on timer. The set up figures are displayed in the bottom of the timer and the counting figures are displayed on the top of the timer. Timer setting: Press the select button and the first digit pipe flashes. Press the “up” button to adjust the figure
42、and press the select button. The second digit pipe flashes. Use this way to adjust all figures for the time. When the setting is done the digit pipe will flash 8 times and the figures are saved to the memory where all data won’t be lost even the power is off. Press the start button the timer begins
43、to count the time. If the power is off the timer will count the time when the power is back next time. The filtration time measures in minute. The maximum time is 9999 minutes. The cleaning time measures in second. The maximum time is 99.99 seconds. Turn to auto state when the power is on. The fil
44、tration process starts for a duration that sets in the timer. In the meanwhile the pressure difference switch also compares the pressure difference between the real situation and the figure that is set up initially. If the duration of time for filtration is up but the pressure differences haven’t me
45、t then the system also starts to open the cleaning valve and begin to clean. The time of cleaning is being counted. When the time of cleaning ends the cleaning valve closes. New cycle begins. In the other situation, if the of duration of time set on the timer hasn’t elapsed and the pressure differen
46、ces have met each other then the system also open the cleaning valves and starts cleaning. The filter stops counting and cleaning process starts to count the time. The system will repeat the process time by time. Picture 11 Adjustment of Pressure difference indicator (Picture 11) The pressure
47、 difference indicator has been set in the factory and the pressure difference is 0.5 Bar. There is an adjusting screw on the low pressure end of the indicator. One clockwise turn increase the pressure difference by 0.06Bar. One anticlockwise turn decrease the pressure difference by 0.06Bar. E.g. If
48、the current pressure difference is 0.5Bar and needs to be changed to 0.2Bar, 5 anticlockwise turns are needed. Vice versa. Adjustment of pressure difference: the indicator can be uninstalled from the system and connect its high pressure end to the pressure-increase equipment and pressure meter if
49、the indicator needs to be adjusted. Observe the movement of indicator. Increase the pressure to the figure needed on the high pressure end. E.g. 0.5Bar is needed for the pressure difference indicator. Turn the adjusting screw when the pressure meter reads 0.5Bar. If the screw moves to the figure of
50、0.5Bar it is the figure for the pressure difference indicator. Service Promise Beijing Luolun (Excel Ethics) filtration Equipment technology Co., regards quality and credit standing as life, insists on the corporate principle “Create with heart, Based on the market”. Aim at meeting
