Removing a Nozzle
Several types of nozzle may be installed on a high‐speed Universal
applicator. In some cases, the nozzle is installed on an adapter. Follow this
procedure to remove or install nozzles and/or adapters as needed. You will
need the following items:
S appropriate tools, including a torque wrench
S drain pans and disposable rags
S replacement adapter and/or nozzle, if applicable
NOTE: Refer to Parts for the part numbers of parts, tools, and supplies.
1. Heat the system to application temperature.
2. Relieve system pressure. Refer to Relieving System Pressure in
Section10, Filter.
3. Trigger the applicator solenoid valves to relieve any remaining pressure.
4. Shut off the module‐actuating air.
5. Decrease the pattern air pressure. Leave just enough air pressure to
prevent adhesive from entering the pattern air outlet on the module.
6. To remove a CF disk or unibody nozzle:
NOTE: A CF disk nozzle is two‐piece nozzle that consists of a nozzle
disk and a retaining nut. A CF unibody nozzle is a one‐piece nozzle.
See Figure 9‐7.
a.. Use a wrench to loosen the nozzle‐retaining nut.
NOTE: Do not use a torque wrench to loosen or remove a nozzle.
Doing so will cause the torque wrench to become uncalibrated.
b.. Remove the nozzle by hand.
