Page 18 5. Cover nearby live sections. If liquid adhesive application system is left idle for extended periods (e.g. overnight or long breaks) Nordson recommends applying Vaseline to the application head nozzles to prevent them from drying out and becoming blocked as a result.
Page 19 Vaseline. Warm water is usually used to flush application systems with which water based liquid adhesives are processed. If the liquid adhesive manufacturer specially recommends a flushing agent, the manufacturer’s safety and disposal details must be followed. E 1995 Nordson Corporation Manual 56- -WM480- -MA- -02 All rights reserved...
Page 20 The use of liquid adhesives in Nordson’s liquid adhesive application systems therefore requires reference to the liquid adhesive manufacturer’s documents beforehand.

Intended Use valves of adhesive guns and proportional valves from Nordson-WALCOM. Any other use is considered as not intended. Nordson will not be responsible for any damages resulting from unintended use.
Page 24 Description The WM 480 is a user-friendly pattern control unit. It is needed to control 3. Introduction solenoid valves which are integrated in adhesive guns. The control is intermittent and independent of the speed of the production machine. In addition, proportional valves with integrated amplifying electronics for pressure control can be triggered.
Page 25 Description The following figure shows the principle use of a WM 480 pattern 4. Functioning controller in a complete system. The principle functioning is described here. All components used conform to the program example described in Operation. A substrate (9) should be applied with adhesive. The transport belt (10) carries the substrates under the guns (7, 14).
