8. Installation, test and operation

8. Installation, test and operation(1)Installationa.The machine should be operated in the room with temperature of 5-40℃ and relative humidity of greater than 80%. Surrounding area of the machine should be clean, dry, free of corrosive gas, well ventilated and direct sunlight.★ Note: Special power line for the machine is recommended with short circuit protection and reliable grounding device. The section area of power cable and melt current of fuse are as follows:b.After unpacking check the machine for any missing parts and damages, check accessories and spare parts and technical document supplied together with the machine according to the packing list.c.Connection of air pipes: connect air supply pipe with the quick coupling(See Fig.1-10 )d.Check if drainage valve is off(See Fig.1-3 ) and pressure switch is at the position of “off”(Switch off position).e.Electrical connection: Check if power supply is normal. Insert the plug for the machine into power supply socket. Installation of the machine is completed.(2)Test run of the machinea.Close drainage valve (See Fig.1-14)and air supply value (Fig.1-4). Check if the reading of pressure gauge (Fig.1-14 ) is below 6 bar. Turn the operation handle of pressure switch to “ON” (Fig.1-9 ) the machine will start immediately. The reading of pressure gauge will slowly rise with increasing pressure inside the air tank. When the reading of pressure gauge reaches 8 bar, pressure switch activates, the power supper is cut off, machine stops running. At the same time the solenoid valve(See Fig.1-11) activates to release high pressure in the cylinder of compression machine so that the machine can be started again; b.During the period when the machine stops running observe if the reading of barometer is decreasing. If there is no leakage of air in the machine, open air supply valve to begin supply of compressed air. When the pressure in the air tank decreases to 6 bar, pressure switch resets and power supply resumes, the machine starts running again. The pressure in air tank increases again. If the machine can automatically stop and start, the machine works normally.
