Air pump for watering

Parts List1. Air Inlet Filter2. Spring3. Motor Coils4. Cylinder5. Rotor6. SF3 Piston7. Valve and Valve Base8. Air Outlet Adapter3InstallationPlace your air pump above the water level in a vertical OR horizontal position. If you place it below the water level you MUST use a valve, this way you will avoid any back flow of water when current falls.OperationNOTE: Your pump is not intended to be used in water. Never place the pump in water. DANGER: In case of accidental submersion in water, discon-nect the power cord before you remove the pump, in order to avoid shock.1. Connect air outlet to the distributer and start the unit. The outlet hose may be connected to the pipe distribu-tors for air stones or air curtains. Each unit can supply air to 6 - 12 pipes. (Fig. 1)2. In case the air exhaust is reduced or without air exhaust, check the connecting parts for leakage; or disconnect the plug, remove the front cover, the valve and the valve base, wash away the dust on them with water, remount with care after drying. (Refer to the cutaway view.) 43. If the unit does not work after connecting the power source, in most cases the connecting point of the diode is broken or obvious shifting happens between the gap of the motor’s piston and housing due to the rough trans-portation. Reassembly of the parts is needed for resum-ing normal operation. (Fig. 2)4. When making the connection, adjust the length of the air outlet hose between the compressor and the reservoir; and ensure the hose is not kinked or blocked. (Fig. 3)5. When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as possible.6. Inspect all mounting screws regularly and ensure that they are properly tightened. Should any of the screws be loose, tighten them immediately. Best of luck on your grows
