1.4 Safety notes
1.4.1 Electrical safety
Electrical safety when handling the 837 IC (Eluent/Sample/Combi) De-
gasser is guaranteed within the scope of Standard IEC/EN 61010-1
(protection class 1, degree of protection IP30). However, please ob-
serve the following points:
• Mains connection
Set the mains voltage and check the mains fuse and mains con-
nection in accordance with the instructions in section 2.5.
• Opening the instrument
Inside the instrument there are no parts which must be set or adjusted
by the user.
The instrument may only be opened by specialized staff of Metrohm. If
the 837 IC (Eluent/Sample/Combi) Degasser is connected to the
mains supply then it must neither be opened nor should any parts be
removed from it, as otherwise the risk of contact with current-carrying
assemblies exists. This is why the instrument should be separated
from all voltage sources before being opened. Please make sure that
the mains cable is pulled out from mains connector 13!
• Protection against electrostatic charges
Electronic components are sensitive to electrostatic charges and can
be destroyed by a discharge. Before touching any assembly within
the 837 IC (Eluent/Sample/Combi) Degasser you should ground your-
self and any tool you are using by grasping a grounded object (e.g.
the instrument housing or a radiator) in order to eliminate any electro-
static charge which may be present.
1.4.2 General safety measures
• Liquid handling
Check all inlet and outlet tubing for leaks at regular intervals. Observe
the appropriate regulations concerning the handling of flammable
and/or toxic solutions and their disposal.
