It can also be ordered from a SIGRIST representative in your country (Instruction Manual
“Customer service information”).
1.8 Proper use
The ScrubberGuard has been developed for monitoring the scrubbing water in exhaust gas
cleaning systems. It is designed for measuring the turbidity, oil in water, pH value and tem-
perature according to MEPC.259(68). The ScrubberGuard has been developed specially for
use on ships.
1.9 User requirements
The instrument may be operated only by trained technical personnel who have read and un-
derstood the content of the Instruction Manual.
1.10 Declaration of conformity
Current technological principles were followed in designing and manufacturing the instru-
ment. They comply with the applicable guidelines concerning safety and duty to take due
care.
EU: The measuring instrument meets all applicable requirements within the European Union
(EU) for carrying the CE mark.
Please refer to the separate declaration of conformity for details. Section 1.4
1.11 Use restrictions
EXPLOSION
HAZARD!
Operation in an inappropriate environment.
Use in explosive areas can cause explosions, which can lead to the death of persons in the
vicinity.
It is not permitted to operate the instrument in explosion hazardous areas or rooms.
It is not permitted to use the instrument with explosive sample substances.

1.12 Removing the casing from the ScrubberGuard
Usually, the ScrubberGuard is equipped with a protective casing. In order to gain a better
understanding of the inner workings of the ScrubberGuard, the system is shown without a
casing throughout this document. The casing can be fitted and removed using a Torx screw-
driver.

1.13 Dangers when not used properly
DANGER!
Operation when not used properly.
Improper use of the system can cause injuries to persons, process-related consequential
damage, and damage to the system and its peripherals.
In the following cases, the manufacturer cannot guarantee the protection of persons and
the instrument and therefore assumes no legal responsibility:
The system is used in a way not included in the described area of application.
The system is not properly mounted, set up or transported.
The system is not installed and operated in accordance with the Instruction Manual.
The system is operated with accessories which SIGRIST-PHOTOMETER AG has not ex-
pressly recommended.
Improper changes have been performed to the system.
The system is operated outside the defined specifications.
The system is exposed to vibrations, shocks or other mechanical forces. These can be
largely absorbed by the rubber buffer and springs used, provided servicing is carried out
according to the servicing schedule (Section 9.1).
