For example, the nominal consumption flow rate is 10L/min, the water supply flow rate should be not less than 15L/min. 2. Do not start the machine if there is no or short of water supply. 3. The inlet pressure of the water supply should be not higher than 0.3Mpa (3 bar), otherwise there is a risk to break the pump or other parts. If the inlet pressure higher than that value, it should be installed a pressure regulating valve the set the inlet water pressure on proper value. 4. In some areas, the water quality is not so good, it is easy to generate the incrustation, please contact professional water treatment firm for help. 5. The machine should be supplied with clean water, Do Not use dirty, rusty or sandy water. --- type of jet round jet This type can generate powerful cylindrical jet flow, it applies for cleaning the very dirty object。 Caution: Do Not shoot the water against people. sectorial jet This type can generate the small sectorial angle and of powerful jet flow, with high efficiency, it applies for quickly cleaning big dirty area. If cleaning the soft object, please keep 20CM safety distance chapter 3 operation instruction Read the machine schematic diagram and operation manual before use, understand each part and its function. Check if the lubrication oil level. 1. Connect well the inlet and outlet water hose. The temperature of the inlet water is not higher than 40°C 2. Connect the water hose on the hydraulic giant Connect the power supply. 3. Connect the water supply, turn the select switch to “cold water” ，then start the machine. 4. Make sure there is no any impurity with outflow water, then mount the jet. 5. Turn the select switch to ”hot water” to heat water. Pay attention: the machine is with the 30s delayed stop function. This function will start when the system pressure is lower than 50 bar to protect the plunger pump. In the first time ， the machine needs a few seconds to establish the working after the pump started. If the pressure can not be established within 30s, the pump will be stopped automatically, and please turn the select switch to “Stop”, then turn to”cold water” to restart the machine till the working pressure established. stop the machine 1. Turn the select switch to “Cold water” to stop the heating. 2. Keep the motor running till all hot water is emitted out, then turn to”Stop” to stop the motor 3. Disconnect the power and water supply. 4. Freeze-proofing, damp-proofing if necessary.
