PRECAUTIONS FOR DECRYSTALLIZATION
• Cycle the chilled or hot and cooling water pumps off and on during the melting pro-
cess.
• Remove any sensors that are sensitive to heat before you start the melting operation.
The temperature of the chilled or hot and cooling water that remains in the absorption
chiller-heater may rise to about 158°F.
• When you start the chiller-heater after melting the crystals, discharge the chilled/hot
water and cooling water first. If that water is left in the machine, the paint on the inside
walls may be peeled off.
