Install the nozzle assembly at an appropriate position on the machine tool, and align the nozzle with the material to be coated. Use a round bar with a diameter of 0.5 inch (12.7mm) to fix the pneumatic needle valve nozzle assembly vertically or horizontally.

Note: The nozzle must be carefully protected when moving and installing the nozzle assembly.

·The connecting solenoid valve and filter/pressure regulating valve shall be installed on the nozzle assembly. The solenoid valve must be close to the nozzle assembly to avoid prolonging the switching time of its control nozzle assembly.

·Connect the connecting end of the insulation pipe and the hot melt glue machine to the glue outlet joint of the hot melt glue machine manually, then use an open-end wrench to properly tighten it, and then connect the power plug.

·The other end of the insulation pipe is connected and locked on the joint of the nozzle assembly, and the power plugs of the two should also be connected together.

Note: Do not keep moving the insulation pipe on the large and cold floor or metal surface to cause the temperature of the insulation pipe to be too low.

·Adjust the pressure on the pressure regulating valve to zero, and then connect the air duct.

Note: When the air pressure provided is transmitted through the filter/pressure regulating valve device, the minimum pressure shall be greater than 30psi (205kpa) to ensure that the nozzle combination can operate normally.
