Installation3-4Part 1032059B  2003 Nordson CorporationManual 41-DURABLUE-MA-02Electrical PowerBefore installing the melter, ensure that the melter will not be overloadedand that the plant’s electrical service is rated to handle the power requiredby the melter and the hoses and guns that you plan to use.Refer to Appendix A, Calculating Melter Power Requirements, forinformation about how to calculate the maximum allowable hose lengthsand gun wattages that can be used in your manufacturing application.WARNING: Risk of electrocution! Install a lockable power disconnectswitch between the electrical service and the melter. Failure to install orproperly use the disconnect switch when servicing the melter can result inpersonal injury, including death.Other ConsiderationsConsider the following additional factors when determining where to installthe melter. The maximum distance between the melter and each gun is dictated bythe power requirement of each hose. Refer to Appendix A, CalculatingMelter Power Requirements for information about how to determine themaximum allowable length. The operator must be able to safely reach the control panel andaccurately monitor the control panel indicators. The operator must be able to safely observe the level of hot melt insidethe tank. The melter must be installed away from areas with strong drafts orwhere sudden temperature changes occur. The melter must be installed where it will be in conformance with theventilation requirements specified in the Material Safety Data Sheet forthe hot melt being used.
