Quick Setup Guide
1 Introduction
The METTER TOLEDO InTrac
are intended for use in conjunction with specified METTLER
TOLEDO electrodes / sensors, namely pH and redox (ORP)
combination electrodes as well as dissolved oxygen (DO),
conductivity or turbidity sensors. Please read through this
quick set-up guide and the operating instructions carefully
before commissioning, in order to ensure trouble-free use.
Operating and maintenance should be carried out only by
trained personnel and staff who have read and understood
the operating instructions.
2 Safety instructions
h Notice: Before every start-up, the housing must be
checked for:
– Damage to the connections, fastenings, etc.
– Leakage
– Perfect functioning
– Authorization for use in conjunction with other plant
h Notice: The manufacturer / supplier accepts no
responsibility for any damage caused by unauthorized
attachments or for the incorporation of spare parts
which are not of METTLER TOLEDO provenance.
The risk is borne entirely by the operator.
a
Caution: Before the housing is put into operation, the
operator must have already clarified that use of the
sensor in conjunction with the other associated
equipment and resources is fully authorized.
a
Caution: A defective housing may neither be installed
nor put into operation. Faulty containment or
installation out of conformance with regulations and
instructions can lead to the escape of medium or to
pressure surges (explosion), potentially harmful both
to persons and to the environment.
a
Caution: The housing may only be operated together
with the specified electrodes / sensors. If an elec-
trode / sensor is broken it must be replaced immedi-
ately.
a
Warning: Before dismantling the housing or
commencing any maintenance work on it, ensure that
the equipment in which the housing is installed is in a
safe condition (depressurize, no explosion risk, empty,
rinse, vent, etc.).
a
Warning: The electrode or sensor may only be removed
from a mounted retractable housing when this is in the
"service" (retracted / withdrawn) position and the ball
valve is closed, since if the electrode / sensor is missing
from the housing there will be path for the process
medium to escape to the environment.
a
Warning: The housing may only be moved to the
"measure" position when a sensor is fitted and the ball
valve is open. The maximum permissible temperature
and pressure specifications must not be exceeded. The
values depend upon the design and type of the
retractable housing. The relative specifications are
given on the label of the individual housings.
