Installation of the Optional Sample Cooler or Thermostat

Using the Sample Cooler or Thermostat in an Infinity II Sampler
Important Information
•
If the temperature is too warm or too cold in the chiller, check the air vents
first to make sure they are not blocked.
•
If frost and ice build up inside the sample cooler or sample thermostat,
defrost the chiller. This is best done overnight. After defrosting, first check
the drainages of the sample cooler or sample thermostat to make sure they
are not blocked.
•
Waiting for the autosampler to cool down can take 30 min - 45 min or more.
This slow ramping behavior is necessary to avoid icing inside the chiller.
•
If you turn the sample cooler or sample thermostat off:
a
Remove all sample containers or vials from the autosampler.
b
Let the autosampler temperature stabilize to ambient temperature (open
the door far enough for air to get in).
c
Clean the drawers of the sample hotel or the cold reservoir (underneath
the drawers) in the sampler, wipe them down, and dry them well.
N O T E
Do not use mechanical devices or other means to accelerate the defrosting process.
N O T E
Adjusting the sample cooler set points from a colder to a warmer set point will result in
some condensation.
N O T E
Adjusting the sample thermostat set points from a colder to a warmer set point will take
longer to avoid some condensation.
N O T E
Ramping up from 4 °C to 30 °C with the thermostat happens slowly. It takes more than 1 h
until the instrument reaches the setpoint.
