3.1.6. The radius of the sprue bush (RA) has to be adapted to the radius of the machine nozzle (RM). (RA > RM + 1); 3.1.7. After measuring the heights of all Hot Runner components, calculate the height of the frame plate according to the determined air-gap measure. - Page 7 B - Basic HR System The system is provided with the major components, manifold, nozzles, cylinders, etc., separately. The specific composition of each system is in accordance with the project drawing approved by the client. C - Pre Wired (PW) Eco Modu System The system comes pre-assembled (prewired), with rails, plugs, connections and raccords.
- Page 8 In any case the system has sensitive components which require extra care: - Electrical components - resistances, thermocouples, electrical coils - Tips and torpedoes with high thermal conductivity, but low mechanical strength. - Seals and gaskets susceptible to blows, cuts, or crushing. Identify the type of construction applicable to your system.

CAD file information. In case of doubt or unclear information contact YUDO. 2. Make sure the housing is in proper condition to receive the hot runner and correct position to proceed with assembling without risks for people and equipment. - Page 10 7. Place the system slowly on suitable surface. Take into account that the system has many hot spots that can be easily damaged. It is recommended that this is placed upon easels seating only the manifold. Any anomaly detected in the system must be reported to YUDO. UH-02-Aug16-ENG...
