Normal Operation
NOTE:
Low Temperature Coolers operate at maximum cooling performance.
IMPORTANT:
To protect the compressor from damage, the Low Temperature Cooler
incorporates a special safety switch that delays compressor startup for 10 minutes whenever
power is applied. This 10 minute delay will occur even when power is only momentarily
disrupted.
Immersion Probe Coolers
1. Place the Power Switch / Circuit Breaker in the ON position.
2. Immerse the Cooler’s immersion probe in the fluid to be cooled. Periodically check the temperature of the
fluid to determine if it is dropping at a reasonable rate.
CAUTION:
The IP-60 Immersion Probe Cooler is designed to reduce the temperature
of a fluid in a Dewar flask and can also be used for cold traps in vacuum systems and other
applications. It is intended for use only at temperatures between -60° and -20°C; the
IP-60
IMMERSION PROBE COOLER SHOULD NOT BE OPERATED AT TEMPERATURES ABOVE
-20°C
for extended periods of time.
CAUTION:
Moving the Immersion Probe Assembly while the unit is operating may result in
damage.
Flow Through Cooler
1. Set the circulator’s temperature control to the desired temperature and allow a few minutes for the bath
fluid to begin circulating through the system.
2. Place the FT-25’s Power Switch / Circuit Breaker in the ON position.
3. Periodically check the circulator to determine if the temperature is being controlled as expected.
