Returning the Melter Setup to Factor y Settings
By returning the melter to its factory setting many common melter problems
can be isolated to either a problem with the melter settings or the melter
hardware.
To return the melter to its factory settings, switch the melter off,
simultaneously press the Setup and Right Display Scroll Down keys, and
then switch the melter back on, holding the Setup and Right Display Scroll
Down keys until the letters PUR appear on the right display.
NOTE: If PUR does not appear upon a first attempt at factory reset, switch
the melter off, simultaneously press the Reservoir and Clear/reset keys,
and then switch the melter back on, holding the Reservoir and Clear/reset
keys until the letters PUR appear on the right display. This will reset the
melter as a PUR melter.
