3.2 Heater/Stirrer Set-Up and Programming
3.2a General Information
Circulator Pump
Pump speed is selected via the Main Menu. The MINIMUM setting is used for DGGE applications.
MAXIMUM is recommended where temperature varies frequently and there is a need for fast recovery or when
pumping to multiple external units.
Speed Maximum Pump Outlet Ratings Maximum Pump Outlet Ratings
Selection Line Frequency = 60Hz Line Frequency = 50Hz
MAXIMUM 30 LPM / 5.0 PSI 22 LPM / 3.4 PSI
HIGH 24 LPM / 2.5 PSI 20 LPM / 1.7 PSI
MEDIUM 20 LPM / 1.7 PSI 17.5 LPM / 1.2 PSI
LOW 18 LPM / 1.2 PSI 15.8 LPM / 0.8 PSI
MINIMUM 15.7 LPM / 0.8 PSI 15 LPM / 0.7 PSI
The data in the table above are based on the following criteria:
a. Maximum pump outlet ow rate is measured in liters per minute (LPM) with no restriction on the pump outlet.
b. Maximum pump outlet pressure is measured in pounds per square inch (PSI) at no ow.
c. Water was used as the circulation uid. Water has a viscosity of one centistoke. High viscosity or low-density uids will change
these gures.
Filling the Reservoir
A liquid level that fully covers the heater coil, pump, over-temperature sensor, and at least one inch
(25mm) of the temperature sensor must be maintained. For heating applications, the DTSK tank must
have at least 23 liters of buffer. When running the system with two dual cassettes, buffer volume should
be 24 liters.
