Guide to the Installation and Adjustment of the Low-Temperature Closed-Flash Point Tester: 1. Place the instrument on the workbench platform, and first conduct a visual inspection to check for any damage to the various components, ensure that the fasteners are tight, and verify that all accessories are present. 2. Connect the prepared liquefied gas cylinder to the gas connector on the back of the instrument using a hose. 3. Plug in the power supply and turn on the power switch; a slight \"click\" sound indicates that the pneumatically controlled solenoid valve has received power, which suggests that the instrument is functioning properly. 4. Open the valve on the liquefied gas cylinder, light the igniter, and adjust the gas control knob on the testing box as well as the small knob on the lid mechanism – turn it clockwise to reduce the flow and counter-clockwise to increase it (it is usually already adjusted at the time of manufacture). This should allow the ignition flame to take on a spherical shape with a diameter of 3–4 mm (i.e., the flame shape specified in the guidelines). Check for any signs of gas leakage. 5. Connect the instrument to the cooling water using a hose. If all the above conditions are normal, the instrument can operate properly.
