Instructions for use: 1. Bring a cooling box (barrel) of more than 30 liters. First connect the heater body and the submersible pump with a silicone grease hose, put the submersible pump into the cooling water bucket, turn on the power supply of the water pump, and wait for the water to circulate out. 2. After the thermostat is connected to the bending machine, connect it to the power supply, adjust the knob of the thermostat, clockwise to increase the temperature, and vice versa to decrease the temperature. When adjusting, it is not advisable to rotate too fast, so as not to damage the temperature control element. 3. When the heating tube reaches the required temperature, place the plastic plate that needs to be bent on the heating tank, bake the plate until it can be folded in half by hand, and then bend it at various angles. ?Packing list: Plastic bending machine x 1, circulating water pump x 1, silicone hose x 2, thermostat x 1, hose clamp x 1
