Repairing the ALS Thermostat Module

Introduction into Repairing the Thermostat

Simple Repairs
The ALS thermostat is designed for easy repair.
Exchanging Internal Parts
Some repairs may require exchange of defective internal parts. Exchange of
these parts requires removing the ALS thermostat from the stack, removing
the covers, and disassembling the ALS thermostat. The security lever at the
power input socket prevents that the Thermostat cover is taken off when line
power is still connected.
To prevent personal injury, the power cable must be removed from the ALS
WA RN ING
thermostat before opening the Thermostat cover. Do not connect the power cable to
the ALS thermostat while the covers are removed.
Electronic boards and components are sensitive to electrostatic discharge (ESD). In
CAU TI O N
order to prevent damage always use an ESD protection (for example, the ESD wrist
strap from the accessory kit) when handling electronic boards and components.
Do not disconnect or reconnect the autosampler to ALS thermostat cable when the
WA RN ING
power cords are connected to either of the two modules. This will damage the
electronics of the modules.
Cleaning the Thermostat
The thermostat covers should be kept clean. Cleaning should be done with a
soft cloth slightly dampened with water or a solution of water and a mild
detergent. Do not use an excessively damp cloth that liquid can drip into the
autosampler.
