Introduction to Maintenance and Repair
Introduction to Maintenance and Repair
The module is designed for easy maintenance. The most frequent
maintenances such as maintaining valve heads (if optional valve drive is
installed) or replacing low dispersion heat exchangers can be done from the
front with module in place in the system stack.
NOTE
There are no serviceable parts inside.
Do not open the module.

Cautions and Warnings
Cautions and Warnings
WARNING
Toxic, flammable and hazardous solvents, samples and reagents
The handling of solvents, samples and reagents can hold health and safety risks.
➔When working with these substances observe appropriate safety procedures (for
example by wearing goggles, safety gloves and protective clothing) as described in
the material handling and safety data sheet supplied by the vendor, and follow good
laboratory practice.
➔The volume of substances should be reduced to the minimum required for the
analysis.
➔Do not operate the instrument in an explosive atmosphere.
CAUTION
Hot heat exchangers
The column compartment has two heat exchanger assemblies that might be hot.
➔Allow them to cool down before starting repairs.
WARNING
Electrical shock
Repair work at the module can lead to personal injuries, e.g. shock hazard, when the
cover is opened.
➔Do not remove the cover of the module.
➔Only certified persons are authorized to carry out repairs inside the module.

Cautions and Warnings
WARNING
The module is partially energized when switched off, as long as the power cord is
plugged in.
Repair work at the module can lead to personal injuries, e.g. electrical shock, when
the cover is opened and the module is connected to power.
➔Always unplug the power cable before opening the cover.
➔Do not connect the power cable to the instrument while the covers are removed.
WARNING
Personal injury or damage to the product
Agilent is not responsible for any damages caused, in whole or in part, by improper
use of the products, unauthorized alterations, adjustments or modifications to the
products, failure to comply with procedures in Agilent product user guides, or use of
the products in violation of applicable laws, rules or regulations.
➔Use your Agilent products only in the manner described in the Agilent product user
guides.
CAUTION
Safety standards for external equipment
➔If you connect external equipment to the instrument, make sure that you only use
accessory units tested and approved according to the safety standards appropriate
for the type of external equipment.
CAUTION
Sample degradation and contamination of the instrument
Metal parts in the flow path can interact with the bio-molecules in the sample leading
to sample degradation and contamination.
➔For bio-inert applications, always use dedicated bio-inert parts, which can be
identified by the bio-inert symbol or other markers described in this manual.
➔Do not mix bio-inert and non-inert modules or parts in a bio-inert system.

Cleaning the Column Compartment
Cleaning the Column Compartment
To keep the module case clean, use a soft cloth slightly dampened with water,
or a solution of water and mild detergent.
WARNING
Liquid dripping into the electronic compartment of your module can cause shock
hazard and damage the module
➔Do not use an excessively damp cloth during cleaning.
➔Drain all solvent lines before opening any connections in the flow path.

Changing Column Identification Tags
Changing Column Identification Tags
The column compartment is equipped with a column-identification system,
that stores column specific information. Two identification tag readers are
incorporated in the heat exchanger assemblies.
Figure 25 Column-Identification System
1The identification tag can be easily removed from the column.
2The tag needs to be placed differently, depending on whether the column is
installed at the left or right heat exchanger, see Figure 26 on page 118 and
Figure 27 on page 118. The Agilent logo should always be at front.

Changing Column Identification Tags
When correctly placed on the heat exchanger, the distance between tag and
tag reader is 1 – 2 mm. This is the optimum distance for proper function.
Figure 26 Column-Identification Tag for Left Heat Exchanger
Figure 27 Column-Identification Tag for Right Heat Exchanger
3For columns with small diameter, a cable tie wrap should be used to fix the
column identification tag to the column. Assure that the tie wrap does not
block the front cover.

Adding Heater Devices
Adding Heater Devices
The additional heater devices can be arranged in the G1316C in various
locations depending on the application needs. Some examples are shown
below.

Adding Heater Devices
Figure 29 Typical positions of the low dispersion heat exchangers
The heater devices are mounted on a carrier that can be fitted to the left
and/or right heat exchangers.
NOTE
If the additional heater devices are used as shown above, the column identification system
cannot be used. If the column identification system is required, fix the heater devices in the
upper or lower locations or fix them right/left of the current location.
