Electrical Power
Before installing the melter, ensure that the melter will not be overloaded and
that the plant's electrical service is rated to handle the power required by the
melter and the hoses and applicators that you plan to use.
Refer to Appendix A, Calculating Melter Power Requirements, for information
about how to calculate the maximum allowable hose lengths and applicator
wattages that can be used in your manufacturing application.
WARNING! Risk of electrocution! Install a lockable power disconnect switch
between the electrical service and the melter. Failure to install or properly
use the disconnect switch when servicing the melter can result in personal
injury, including death.
Other Considerations
Consider the following additional factors when determining where to install
the melter.
S The maximum distance between the melter and each applicator is
dictated by the power requirement of each hose. Refer to Appendix A,
Calculating Melter Power Requirements, for information about how to
determine the maximum allowable length.
S The operator must be able to safely reach the control panel and
accurately monitor the control panel indicators.
S The operator must be able to safely observe the level of hot melt inside
the tank.
S The melter must be installed away from areas with strong drafts or where
sudden temperature changes occur.
S The melter must be installed where it will be in conformance with the
ventilation requirements specified in the Material Safety Data Sheet for
the hot melt being used.
