Normally it is enough when the heating temperature is over 20??. Instruction: 1, After unpacking, slightly shake machine and listen if there is noise inside, in order to make sure if any parts are loose inside. 2, Place machine in a ventilated dry place, and ensure machine is at a horizontal position. 3, Add proper amount of cleaning fluid (2/3 depth <L<3/4 depth) as needed. 5, Set ultrasonic work time:after powering on, rotate the right timer knob clockwise to set cleaning time.Indicator light up and a humming sound indicate the ultrasonic cleaner is working. 6, Set heating temperature ( select heating only when it is necessary):Clockwise rotate the left temperature knob to required temperature (20 degrees above is enough), then heating indicator lights up and heating element begin to work. 7, Power off after cleaning:After cleaning, turn off heating element first, then power off.After cleaning fluid is cool, drain it then mop the tank and shell clean using a cloth. Place the machine in a ventilated dry place. Note: 1, When ultrasonic cleaner is working normally, you should hear even sound by ultrasonic and tank's resonance, and there is no big surge on cleaning fluid surface, but only small ripples. If there is intermittent oscillation, please add a little cleaning fluid or discharge a little cleaning fluid, which can eliminate oscillation and good for cleaning. 2, If possible, keep it work intermittently and do not use heating function, because heating function and continuous long-time work would cause high temperature inside the machine and accelerate aging of electronic device. 3, Must not use flammable and corrosive detergent. 4, Must not turn on heating or ultrasonic function when there is not enough cleaning fluid in tank. 5, Prevent cleaning fluid and water from entering machine inside, otherwise electronic components will be burned out. 6, Any foreign objects that fall into the bottom of tank should be take out immediately (do not take it out with hand directly, in case of injury). 7, When replacing or draining cleaning fluid, the fluid temperature should be normal temperature, and make sure to power off and unplug the power cord.(after cleaning, tank should be drained dry) 8, Keep machine outside clean during cleaning, and keep machine inside and outside clean and dry after cleaning. 9, Each cleaning time should not be too long. Suggested to power on for 15 minutes then power off for 5 minutes to dissipate heat, in order to protect machine and prolong service life. Package Includes: 1 x Ultrasonic Cleaner
