•  The SMC unit has a leaving water temperature range of 30°F (-1°C) to 65°F

(18°C). Do not attempt to run the SMC unit outside this temperature range or
damage to the unit may occur.

 

•  When operating the SMC unit between 30°F (-1°C) and 40°F (5°C), you must

use a solution of 75% water and 25% industrial-grade ethylene glycol with a
suitable corrosion inhibitor to protect the SMC unit from freeze-up. See
Figure 5 on Page 17 for more information. Such damage is not covered by
the Sterlco warranty.

;

  Process cooling water supply and return connections are made at the pipe stubs at the rear of

the chiller.

;

  Warm water returns from the process and enters the reservoir tank.

;

  The process water is pumped through the evaporator where it is cooled.

;

  The coolant flows to the process and returns to repeat the cycle.

;

  A chilled water bypass assembly (patent pending) between the supply and return lines

guarantees a constant flow through the evaporator during intermittent low or no-flow
conditions.

;

  A flow switch in units without pumps will prevent the compressor from running without

adequate flow through the evaporator

„

  Liquid refrigerant from the condenser passes through a filter/dryer which removes moisture

and other contaminants.

„

  The refrigerant then passes through the thermal expansion valve which allows the

refrigerant to expand and cool the inside of the heat exchanger. The refrigerant flows
through the suction line to the compressor.

„

  The refrigerant gives up its heat as it re-condenses to a liquid in the condenser and the cycle

starts over again.
