Other Considerations

Part 1024496_06
To achieve maximum hot melt output, 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.
NOTE: The minimum operating air pressure is 0.7 bar (10 psi). Operating
the melter with the air pressure set to less than 0.7 bar (10 psi) may cause
the pump to function erratically.
Nordson recommends that an isolation valve be installed in the plant air
supply line just before the melter.
Consider the following additional factors when evaluating where to install the
melter.
S
The maximum distance between the melter and each gun 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 so that it can be safely removed from its
sub‐base.
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.
S
The melter should not be exposed to excessive vibration.
S
P4 and P7 melters provide an auxiliary hose port at the bottom of the
manifold. If the auxiliary hose port will be used, the parent machine or
other support structure must provide clearance under the melter to
connect the hose to the auxiliary hose port.
