Safety and Operating Instructions The following safety precautions should always be followed to reduce the risk of breakdown and/or accident. ATTENTION To Prevent Electric Shock And Fire Don, t install the blower where it will be flooded with water. Electrical work must be done by a qualified electrician. The power supply should be the rated voltage shown on the label on the blower and be fitted with an earth leakage breaker and over current breaker. The power outlet used should be waterproof and include an earth connected to ground. 5 If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or similarly qualified person in order to avoid a hazard. 6 Don, t place any objects on the electric cable. 7 Be sure to unplug the blower before starting maintenance. 8 Be sure to put the Upper Case back after maintenance.

. Installation (Septic Tank Application). Installation site selection 5 6 7 8 Install our blower near the septic tank. If the pipeline is long, the sewage treatment may not perform well due to an insufficient airflow. Install in a place which is convenient for maintenance. Don, t install over a manhole or on soft ground. Avoid areas where wind-blown leaves and dust gathers. Install in a well ventilated place. Install at least 0cm away from the wall of a house. Installation in the shade is recommended to suppress heat generation of the blower. Don, t install the blower where it will be flooded with water. Make sure that the blower is installed over the water level ot the sewage tank/aquarium to avoid any backflow of the water. If the blower is installed under the water level a backflow valve must be used. Don, t install where there is excess moisture or humidity.. Method of Installation The base should be made of concrete strong enough to bear the weight and block vibration from the blower. The base should be at least 0cm above the ground level and 5cm larger than the external dimensions of the blower. Provide a separate power outlet to be only used for the blower. Electrical work must be done by a qualified electrician. 5 The power supply should be the rated voltage shown on the label on the blower and be fitted with an earth leakage breaker and over-current breaker. 6 The power outlet used should be waterproof and include an earth connected to ground. 7 Place the blower horizontally on the base. 8 A soft rubber hose must be used for connection between the air outlet of the blower and the pipe. The rubber hose must be fastened with hose clamps. 0 When making the connection, level the air outlet and the pipe to ensure the hose is not kinked or blocked. Before starting the operation of the blower, ensure that the water level in the septic tank is appropriate and the valves on the pipeline are properly opened.. Start operation Insert the power plug into the power outlet with full contact so that the plug itself does not wobble. Incomplete connection may cause an electric shock or a fire. After starting operation ensure that there is; No air leakage from the hose and the pipe connection. No abnormal noise from the blower. No vibration transmitted to the ground due to strained piping.

5. Maintenance (Refer the sketches on the next page). Cautions MEDO blowers are OILLESS. Never lubricate them. All blowers have already been precisely adjusted. Never disassemble them. (Do not try to loosen the Hex. bolts on the Endcap). Safety Instruction. Replacement of Filter Element Be sure to unplug the blower before starting the replacement work. Loosen the Bind Screw and remove the Filter Cover. Remove the Filter Element(s) 5 from the Upper Case 6 and replace with new One(s). At the same time, clean the air inlet of the Filter Cover and the Upper Case 6. Assemble the Filter Cover with the Filter Cover Gasket securely positioned. 5 Mount the Filter Cover to the Upper Case 6, then tighten with the Bind Screw(s). 6 Time to replace the Filter Element It is recommended that the Filter Element(s) is cleaned or replaced with new one(s) depending on the extent of its deterioration as determined by the atomospheric conditions around the application. The filter element(s) should be checked every three months and should be replaced jearly.. Replacement of Piston Set Assy Be sure to unplug the blower before starting the maintenance work. Remove the Upper Case 6, loosen all the Hex. Bolts on the Headcover 0 and remove it. In case it is hard to remove the Headcover 0 insert a flat head screwdriver to the slot(s) on the edge of the Headcover 0 and twist the screwdriver gently to open. Take out the Piston Set Assy(s). Replace all Piston Set Assys, Gasket A and Gasket B with new ones. Be sure to keep the Teflon Seal of the Piston away from any dust, swarf, water, oil or grease. Try not to touch the Teflon Seal of the Piston with your fingers. 5 Insert the Piston Set Assy(s) into the Pump Body. Install Gasket A on the Headcover 0 and Gasket B on the Pump Body, then fasten the Headcover 0 with the Hex. Bolts.Tighten the Hex. Bolts evenly and alternately then gradually fully tighten. 6 Before putting the Upper Case 6 back, start the blower and check if there is any air leakage along the Headcover 0 or the Nozzle Seal(s) by briefly blocking the air outlet. In case there is an air leakage along the Headcover 0, re-position Gasket A and Gasket B then re-fasten the Hex Bolts. In case there is an air leakage along the Nozzle Seal(s) chec k if the nozzle seal is installed on the airtank properly and press the pump body down to allow the outlet port of the Headcover to catch the Nozzle Seal(s) correctly. 7 Put the Upper Case 6 back after installing GasketC 8 on the Bottom Case properly. Fasten the Bind Screws/Torx Screws 7 evenly and alternately. Piston Slot 8 Piston Set Assembly replacement period It is suggested that the Piston Set Assembly is replaced every months resp. after 0.000 h depending on the extent of the blower s pressure and airflow deterioration. There is a groove on each Teflon Seal of the Piston indicating the degree of wear. If one or both grooves are worn away, replacement of the Piston Set Assembly is recommended.
