Precautions for De-crystallization
• Cycle the chilled and cooling water pumps off and
on during the melting process.
• Remove any sensors that are sensitive to heat be-
fore you start the melting operation. The tempera-
ture of the chilled and cooling water that remains
in the absorption chiller may rise to about 158°F.
• When you start the chiller after melting the crys-
tals, discharge the chilled water and cooling water
first. If that water is left in the machine, the paint
on the inside walls may be peeled off.
