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 guns 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 gun
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 i n personal
injury, including death.
Compressed Air
The melter must be connected to an air supply that is capable of providing a
maximum of 6.2 bar (90 PSI) of dry, nonlubricated air. The actual pressure
required for the melter to support your manufacturing process will depend on
such factors as the type of hot melt and gun you are using and the required
dimensions of the hot melt bead.
Nordson recommends that an isolation valve be installed in the plant air
supply line just before the melter.
