WARNING @When the sewage treatment device Is stopped to use, empty it after cleaning the inside of the sewage treatment tank. If sewage has been left in the tank, the sewage will go bad, resulting In the production of a poisonous gas. The | _ inhalation of the gas may cause death, @When the inside of the sewage treatment | tank is inspected, check the concentration | of the gas, then carry out the work after | _ safety has been verified. @A place where the sewage treatment device has been installed must be well ventilated. Since a large quantity of air is fed to the device, there is a possibility that the surrounding area falls into a hypoxia state. @in handling a disinfectant, follow the disinfectant handling standards. The wrong handling of the disinfectant may cause the accidents involving a human life. @WWhen the discharge pump. the aeration blower or the level switch is examined, tum off the control panel breaker. Also, turn the control switch off. In addition, tag the control panel as "Energizing Is Prohibited’ , so that the switch is not tured on by mistake. @When the discharge pump, the sewage pipe and valve, are overhauled, carry out the work under ventilation, since sewage may contain a poisonous gas. @in climbing on the sewage treatment tank, wear a heimet and the gloves and shoes with a slide stop function. Also, when the work is carried out at a high place, wear a safety belt. A fall from the place may ‘occur, result in the accidents involving a human life. @The work for maintaining and checking the inside of the control panel should be carried out by electrician with expert knowledge. The accidental contact with the high-voltage current may cause the death by an electric shock. @Do not use chemicals for cleaning of toilet. The chemicals will affect and kill the microorganisms in the tank. This will cause loss of the purification ability, resulting in the production of a poisonous gas or a bad smell. Use a cleaner which does not give damage to the microorganisms. @The aeration blower should be run continuously. The interruption of its continuous running will kill the microorganisms within the sewage treatment tank. This will cause loss of the purification ability, resulting in the production of a poisonous gas or a bad smell. Also, there is a possibility that the air discharge nozzle clogs. @Do not put fingers or objects into the rotaty parts of the discharge pump and the aeration blower. There is a possibility of injury. (@Sewage may leak aut from the shaft seal part of discharge pump due to the termination of its service life. The sewage that leaked out will go bad and then produce a poisonous gas, resulting in the accidents involving @ human life, or in corrosion or failure of implements. Clean the area under ventilation, and stop the leak by replacing parts with new ones. @The inner surface of the sewage trearment ‘tank has been coated with tar-epoxy. Do not bring fire close to the tank, or the coating will be damaged, thereby causing sewage to leak out from damaged portions. of the tank, @Close the manhole of the sewage ‘treatment tank so securely that sewage or ‘odor will not leak out. @Check the air vent pipe for the clogging because of sewage or dewing. If the pipe clogs in this way, the toilet seal water trap will be broken by the back pressure of the aeration blower, thereby causing the toilet water to splash and at the same time resulting in the emission of e poisonous bad smell. Also, the splashes dirty your clothes and the surrounding area, @The paper to be used in the toilet should be soluble in water. Stutfs which are insoluble in water, such as sanitary product, should not be thrown into the toilet but be thrown into a waste-basket placed in the toilet. These stuffs may cause the clogging or failure of the pump.BLSEWAGE TREATMENT DEVICE SBT 1.

Level Probe 11.1 General Scope of Level Probe This Sewage Treatment Device equips a. capacitance type level probe in the sterilization compartment. This level probe which is series of sensors detects the level of water in the sterilization compartment at each level, gives the signal for starting and stopping the discharge pump, and provides warning for abnormal high water level to the level switch unit. Since the sterilization compartment is isolated, visual check is not possible from the outside. Therefore, the water level can be only checked by the lighting of level indicators on the level switch unit inside of the control panel as shown below. Timers are incorporated in each sensors for the pump start level and high water level ‘The former has the function to automatically stop the pump if the sensor in pump stop level fails: it will be adjusted depends on sterilization compartment's size (MAX 20 seconds). The later is designed to avoid any undesirable activation due to water splash: the timer provides warning signal 15 seconds after the sensor was sunken into the water. 11.2 Working Principle This level probe detects the difference of boundary surface between the water and the air as variation of capacitance and transmits the signal to the level switch ut The value of dielectric constant significantly changes between the water and the air. This variation is turned into the strong ” weak circuit transmit voltage and is applied as on / off signal of the relay circuit in the level switch unit. 11.3 Confirm Operation Pump Ston Water Level ~ Lamp 'L’ Lights Pump Start Water Level ~ Lampe ‘LH Light IGH Water Level ~ All Lamps Light Adjustment Trimmer OF ‘Timer For Pump Stop (max 20s) eleclanler ole] Level Convallor Ineicator Lampired? CHE} Fig.6 Level Switch Unit (inside Of The Control Panel) 11.4 Abnormal working If the automatic starting and stopping of pump and high level alarm is not working normally, we suppose that the cause of above is by the problem of Level Prove. In this case, please carry out the following investigation. 8. Open the cap of level prove, and disconnect the wiring of terminal “P” and “E”. All LSU operation lamps of “L”, “H’ and "HH" in control panel are put off at the disconnection of wiring. If above lamps are not put off, the LSU Is defected so that there is need to replace it. b. If there is no defected for the LSU, there is possibility that the level prove is out of order. It is possible to pull out the censer part by take off two (2) screws that is fitted beside of level prove terminal box. Please check whether there is any breaking of wire or otheres defected part ‘on each censer part or not. c. Wiring the sensor line under the condition that the sensor part is pulled out, Each sensor line is corresponded to the operating light that is installed on LSU in the control panel. (in order L.H, and HH from bottom side) If you clasp the sensor L, the operating light of L is output. If you grip the sensor H with grasp the sensor L, the operating, light of L and H are output. (if you only clasp the sensor H, the operating light is not output.) If you grip the sensor HH more than 15 seconds, the operating light of HH is output. (If you only calsp the sensor HH, the operating light is output) d. If you clasp the sensor, and the operating lights are not output normally, the Level Prove is out of order. Therefore, there is need to replace all of them. @. If there is no abnormal part on level prove by above inspections, there is possibility ‘that some material is stuck on the level prove pipe so that please remove them by ull out the level prove. f.
