14 、One booster pump, the power is 1.1KW , the lift is 30-50 meters, and there is another pool with a volume of 3-4 cubic meters.

5, equipment standard configuration:

6 , customer self- installed machine accessories ( circulation cooling system ) :

    1. Three-phase air switch 400A                 One

2. Power connection flexible cable 90 mm2            a few meters

3 . Cooling tower 30 tons      1;

4. Pump 3.0kw/head 30-50 meters 1 set;

5, equipment inlet and outlet water pipes: high pressure enhanced water pipe outer diameter 16 mm, inner diameter 12 mm several meters

6, water pump inlet and outlet water pipe: 1 inch (inner diameter 25 mm) within the wire high pressure reinforced pipe several meters

7. Operation steps of the equipment :

1, electrical connection: access to a dedicated power supply line, respectively, three-phase air switch. Then connect the ground wire. ( Note that the three-phase electric power should be able to meet the use of the equipment, and the wire thickness should be used according to the instructions )

2, water: (depending on continuous working time and workload) select the cooling water system to achieve water circulation cooling.

3, through the water: open the waterway, and check the equipment every water to see if there is water outflow, the flow and pressure is normal .

4, power: first open the control power switch , then open the air switch behind the machine, and then turn on the power switch on the control panel.  

5. Startup: The heating power potentiometer should be adjusted to the minimum before starting the first furnace. After the start, the temperature should be adjusted to the required power. Press the start button to start the machine. At this time, the heating indicator on the panel lights up, and the prompt sound of normal operation and the work light flash simultaneously. 
6. Observation and temperature measurement: During the heating process, it is mainly determined by visual means to determine when to stop heating.

7. Shutdown: Shutdown, the control device switches off first, then turn off the main power external switch, then delayed until about 1 hour after the furnace temperature down; then off equipment cooling water, heat the inside of the machine and to facilitate induction coil Heat is emitted. 
8. In the area where it is easy to freeze in winter , it should be noted that after each use, compressed air should be used to blow out the water in and out of the equipment to prevent water from cracking internal fittings and water pipes inside the equipment .
