1. Installation of inductor: For holistic type the inductor connect with secondaryjoint of main control tank directly; for separate please connect the inductor with transformer well and guarantee good contact. The interface of the transformer and inductor should have no water leakage.
2. Connection of cooling water: The inlet and outlet pipe should be connected reliablyaccording to the tablet indication on the engine case. Please make sure that there are no wrong connection, aleak phenomena and seeper in chassis. Please do not sprinkle water into chassis. If it happens please cut off thepower supply and drying it.
3. Connect to earth: The frame must be reliable protective bonding to neutral withmore than 6mm2 copper wires for three-phase four-line system. It should comply with the standard of electric work.
4. Please connect feet switch with the interface of remote control switch.
5. For separate type induction heating equipment please connect the main control tankwith the transformer as the line number accordingly. Please connect the induction coil joint with the transformer secondary joint.

IV．Operation Precautions
1. Please ensure the casing connects to earth in accordance with the standard of electricwork to prevent from electric shock.
2. Dismantle and installation of inductor must be done after stopping heating.
3. Firstly connect the equipment with water and then connect it with power. The innerof equipment and inductor must be cooled down with clean water to prevent the cooling pipe from blocking. If the equipment supplies water with pump, please install filter screen at pump intake. Temperature of cooling watershall not be higher than 37℃ with water flux 10T/h (It is better to use intenerated water), or else will lead to equipment alarm even overheating damage.
4. The equipment must be avoided insolation, drench, dampness and dust. Please carrythe serving and maintenance after power off one hour.
5. Please make sure the induction coil is clean to avoid short circuit between theturns of inductors.
6. The equipment cannot use loop inductor, which will make inductive reactance toolow and lead to damage of equipment. Under special circumstance, please consult with manufacturer.
7. The cooling water must be clean without impurity. It is prohibited to be shortof water under work condition. Please set a filter at the entrance of suction stroke.
8. Descale the waterway of equipment with the detergent (we supply it) every fourmonths. Please clean immediately when the alarm indicator lamp for water temperature is on frequently or water current from the out water gap is decreased patently.
9. Clean the inner of equipment: Blow it clean with compressed air or blowing machine.Clean the circuit board with brush and then blow it.
10. Inductor connect board must be polished with a sand paper to keep good electricalconductivity if you replace inductor.
