Foundation and distance to the wall 
◆ Foundation requirements: The smooth concrete pavement of 100mm in the thickness above the original ground is all right and it’s unnecessary to reserve the foot foundation.
◆ Requirements for distance to the wall: It’s required the distance to the wall is not less than 500mm with the span of more than 1m above the top of the equipment for the convenience of the equipment maintenance.
Wiring requirements: 
The power supply of the equipment control part is of 220V/50Hz and the electric valve is of AC220V/50Hz or AC380V/50Hz. The power supply control cabinet and the equipment can be connected with the hard cable spool or by soft connection according to the actual conditions on the site.
Operation state display: 
The filtering indicator, back-washing indicator will be lighting when the equipment is in the filtering or backwashing state. The voice and light alarm will be flashing and buzzing in case of the equipment alarm. The dosing pump indicator will be lighting when the dosing pump in working state and the low fluid level indicator will be lighting in case of the dosing fluid used up in the dosing barrel.
Fault 
◆Breaker tripping and short circuit: please examine whether there is short circuit of the equipment cable.
◆Electric actuator failing to be in place and fault alarm: generally, the valve plate is blocked by debris or other objects, which should be cleared. It is also caused possibly by the electric limiter block failing to be in place. The limiter block should be adjusted after opening the top cover of the actuator.
Operation descriptions (operation notes) 
Such water treater is the comprehensive equipment with integrity of the fully automatic comprehensive water treater and the automatic dosing device.
Fully automatic water treater operation procedures:
◆Starting: to examine whether the Manual/OFF/Automatic rotary knob on the equipment panel is in OFF position before starting the equipment; to switch on the air switch of the power supply in the cabinet and the green filtering indicator will be lighting and the red back-washing indicator will goes out after starting. Meanwhile the electric valve will operate automatically and adjust to the normal filtering position after the starting and the equipment will be in normal filtering operation mode.
◆ Washing pressure difference automatic setting: The pressure difference should be set up within the adjustment range of 0.1­2.0kg/cm²;
◆ Inlet and Outlet pressure measurement and indication: the pressure sensor is used to make sampling of inlet and outlet pressures and the programmable controller will make measurement and treatment automatically. The monitor will display the water pressures at the inlet and outlet simultaneously with the unit of kg/cm²;(The monitor will display the inlet and outlet pressure values after starting)
◆Automatic control: (Manual/OFF/Automatic switch: on the operation position of Automatic ) When the pressure difference of the inlet and outlet exceeds the setting value continuously, the equipment will make back-washing automatically with the green filtering indicator going out and the red back-washing indicator lighting. The equipment will ① turn on the bypass valve; ② turn off the inlet valve; ③ shut off the equipment electrical assembly power supply; ④ turn on the blowoff valve; ⑤ make back-washing according to the setting time and then the equipment will enter returning program after the blowing off; ⑥ turn off the blowoff valve; ⑦ turn on the equipment electrical assembly power supply; ⑧ turn on the inlet valve; ⑨ and turn off the bypass valve. The equipment will make filtering after turning off the bypass valve and the green filtering indicator will be lighting and the red backwashing indicator will go out. The equipment will return to the filtering monitoring operation state after the completion of the whole abovementioned procedures.
◆Manual back-washing: (Manual/OFF/Automatic switch: on the operation position of Manual) the equipment will make the backwashing with the same abovementioned procedure when the Manual/OFF/Automatic switch in the manual control state.
◆ Automatic washing control mode selection: the equipment can make backwashing automatically in two modes of the inlet and outlet pressure difference and the set time, which can be selected by the monitor. The control mode can be changed by pressing SHIFT+F7 or SHIFT+F8 on the automatic washing control mode selection page. The number of 1 indicates the current control mode of the equipment. For example, the pressure control mode is displayed by 1 and the time control mode is displayed by 0 in case of the pressure control mode being current (defaulting setting). Then the control mode will be shifted into the time control mode by pressing SHIFT+F8. 
◆Equipment parameter: The equipment parameters are set up in default as follows with the values in brackets indicating the setting range:
Backwashing pressure difference: 0.8Kgf/CM2 （0.1-2.0 Kgf/CM2）
Pressure difference exceeding limit time: 50minutes (1-50minutes);
Back-washing time: 30s (1-50s);
Valve alarm time: 6min (4-30min);
Time automatic control mode back-washing interval: 100h (1-2,000h).
◆ Equipment parameters setting method: All parameters will be effective only after the manual setting (Note). All parameters will be set in corresponding text interfaces: to press ENTER in the text panel, then the parameter will display in inverse color; to press the ↑and ↓ to change the parameters and to press ENTER for confirmation.
◆ Equipment fault alarm: F6 is the trial key to test whether the buzzer can work normally when the equipment is not in alarm. When the valve fails to be in place within the set time, the buzzer will flash and buzz for alarm, informing the operator to make maintenance and repairs.
Automatic dosing device operation procedure:
① Starting: to examine whether the Manual/OFF/Automatic rotary knob on the equipment panel is in OFF position before starting the equipment; to switch on the air switch of the power supply in the cabinet and the dosing will stop.
② Manual control: (The equipment is controlled with the panel rotary knob when the equipment is controlled manually) to switch the Manual/OFF/Automatic rotary knob to Manual, the dosing pump will start to work in the manual operation mode.
③ Automatic control: (The dosing pump operates automatically according to the set time when the equipment in automatic control mode) to switch the Manual/OFF/Automatic rotary knob to Automatic, the equipment will operate automatically and the dosing pump will operate automatically according to the set time. The operation and stopping time of the dosing pump will be set on corresponding text interfaces to control the operation of the dosing pump. All parameters will be set in corresponding text interfaces: to press ENTER in the text panel, then the parameter will display in inverse color; to press the ↑and ↓ to change the parameters and to press ENTER for confirmation.
④ Alarm: The system will stop the operation of the dosing pump and make alarm to the operator to add the chemicals in time when the chemicals in the dosing barrel are used up.
Equipment operation notes:
① The equipment should have the sound ventilation and the voltage fluctuation should be not larger than 10%;
② The examination should be made on the operation performance of each electric actuator and dosing pump and whether the dosing pipelines are connected correctly before the equipment is put into operation. The equipment should be put into normal operation only passing the examination;
③ The air tightness examination should be made regularly on the valves and pressure meters of the equipment to avoid possible water leakage and corrosion.
