Safety hazard symbol notice
The symbol indicates a potential hazard. Consult the documentation for important
information about the hazard and the appropriate measures to prevent and control the hazard.
Considerations specific to the Column Heater-Active
Warning: To prevent burn injuries, set the column temperature to Off, and then allow
the column compartment and its components to cool for 60 minutes before touching
them. Monitor the column compartment's internal temperature to ensure that all
components are cool.
Warning: To avoid combustion, do not use the column compartment with solvents
whose autoignition temperatures are below 150 ºC.
See also: For safety considerations regarding specific system modules, consult the appropriate
information on the user documentation CD.
FCC radiation emissions notice
Changes or modifications not expressly approved by the party responsible for compliance, could
void the user's authority to operate the equipment. This device complies with Part 15 of the FCC
Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received, including interference that
may cause undesired operation.
Canada spectrum management emissions notice
This class A digital product apparatus complies with Canadian ICES-001.
Cet appareil numérique de la classe A est conforme à la norme NMB-001.
Equipment misuse notice

Audience and purpose
This guide is intended for individuals who install, operate, and maintain the column heater with
the active pre-heater (CH-A).
Intended use of the CH-A
Waters designed the CH-A for use in liquid chromatography (LC) applications. The CH-A is not
intended for use in diagnostic applications.
Calibrating
To calibrate LC systems, adopt acceptable calibration methods using at least five standards to
generate a standard curve. The concentration range for standards must include the entire range
of QC samples, typical specimens, and atypical specimens.
Quality control
Routinely run three QC samples that represent subnormal, normal, and above-normal levels of a
compound. If sample trays are the same or very similar, vary the location of the QC samples in
the trays. Ensure that QC sample results fall within an acceptable range, and evaluate precision
from day to day and run to run. Data collected when QC samples are out of range might not be
valid. Do not report these data until you are certain that the instrument performs satisfactorily.

EMC considerations
Canada spectrum management emissions notice
This class A digital product apparatus complies with Canadian ICES-001.
Cet appareil numérique de la classe A est conforme à la norme NMB-001.
ISM classification: ISM group 1 class B
This classification has been assigned in accordance with CISPR 11 Industrial Scientific and
Medical (ISM) instrument requirements.
Group 1 products apply to intentionally generated and/or used conductively coupled radio-
frequency energy that is necessary for the internal functioning of the equipment.
Class B products are suitable for use in both commercial and residential locations and can be
directly connected to a low voltage, power-supply network.
