Required pump size depends on chiller model, water volume and rate of circulation. Recommended
pump sizes for effective water chilling are within the following ranges:
CHOOSING THE CORRECT EXTERNAL PUMP
Water level inside the reservoir is correct and there are no leaks in any hoses or connections.
Power supply is correct and the plug is inserted completely into the outlet.
Double-check the whole system to make sure there are no breaks or clogs.
For the most effective water cooling and energy efficiency, locate chiller below water level. If chiller
must be placed above reservoir level, make sure height above pump does not exceed 26 ft. (8m).
For best performance, keep hoses as short as possible. The sum of all hose lengths should not
exceed 25 ft. (7.6m).
TYPICAL INSTALLATION
This chiller does NOT have an internal pump for system circulation.
