Service
Regular servicing will ensure the contin-
ued accuracy of your moisture analyzer.
The optimum length of the interval
between service visits depends on the
operating conditions at the place of
installation and on your requirements.
Repairs
!
A defective moisture analyzer must be
disconnected from the power supply
immediately (unplug the cord from the
wall socket). Repair work must be per-
formed by authorized Sartorius service
technicians using original Sartorius
spare parts. Any attempt by untrained
persons to perform repairs may result in
considerable hazards for the user.
!
If a cable is damaged or defective,
replace the cable as a complete unit
with all its connectors.
!
Do not open the LMA200PM moisture
analyzer while it is carrying current.
Allow approximately 10 seconds to
elapse after disconnecting the equip-
ment from power before opening the
equipment housing. Because the integ-
rity of the fitting surfaces is essential
for safe operation of the LMA200PM,
always exercise caution when opening
and closing the equipment housing.
!
When replacing the battery on the PCB,
the same or an equivalent type of
battery (approved by the manufacturer)
must be installed.
To prevent hazard of explosion, make
absolutely sure the polarity is correct.
Cleaning
!
Disconnect the LMA200PM moisture
analyzer from power (unplug the cord
from the wall outlet (mains)) and dis-
connect any data cables.
!
Do not permit liquids to penetrate the
housing of the moisture analyzer. Install
the protective plug/transport locking
device before cleaning the moisture
analyzer.
!
Do not use any aggressive cleaning
agents (solvents or similar agents).
!
Do not wash down the equipment with
water or dry it with compressed air.
§
Clean the moisture analyzer using a
piece of cloth that has been dampened
with a mild detergent (soap).
$
If used in the food industry, make sure
the cleaning agent is suitable for use in
the particular working environment.
§
Dry the moisture analyzer with a soft
cloth.
Cleaning the Sample Chamber
§
Open the cover.
§
Remove the adapter and the sample
retainer.
§
Insert the protective plug before clean-
ing.
Make sure that no liquid remaining
on the sample retainer penetrates the
weighing system.
§
Use a lint-free, anti-static laboratory
wipe or cleaning cloth to carefully
clean the sample chamber, including
the inside of the cover. Make sure the
sealing surface between the sample
chamber and the cover is clean and free
of damage. If a detergent is necessary,
use a gentle cleaning agent.
§
After cleaning, wipe the entire the sam-
ple chamber dry, including the inside of
the cover.
!
Use of a sharp-edged object to clean
surfaces in the sample chamber or, in
particular, the sealing surfaces between
the upper and lower parts of the sample
chamber is not permitted, as this will
damage the PTFE coating. If any part of
the sealing surfaces between the upper
and lower parts of the sample chamber
is damaged or contaminated, operation
of the moisture analyzer will place the
operator at risk of physical injury. Make
sure no liquid penetrates the safety lock
on the analyzer cover.
§
If necessary, remove the adapter from
the sample retainer carefully and clean
it. When cleaning the sample retainer,
make sure that no liquid remains on
the sample retainer that could penetrate
the analyzer housing.
After cleaning, wipe the sample retainer
dry and then carefully replace it on the
analytical weighing system and turn it
slightly until it clicks into place.
Safety Inspection
Each of the following conditions indi-
cates that safe operation of the moisture
analyzer is no longer ensured:
– Visible damage to the device or power cord
– Defective built-in power supply, cooling
fan or safety switch on the analyzer cover
– Blockage of the analyzer cover or any
of the cooling fans
– Damage or defects to the PTFE
coating of the sample chamber or the
sealing surfaces between the cover
and sample chamber
– Storage of the moisture analyzer for a
relatively long period under unfavorable
conditions (e.g., extreme moisture)
If there is any indication that safe opera-
tion of the moisture analyzer is no longer
warranted, disconnect the moisture ana-
lyzer from power (unplug the equipment
from the wall outlet (mains)) and lock it
in a safe place to ensure that it cannot be
used.
Maintenance and repair work may be
performed only by authorized Sartorius
service technicians who have access to
the required service and maintenance
manuals and have attended the relevant
service training courses.
!
The seals affixed to this moisture analyzer
indicate that only authorized Sartorius
service technicians are allowed to open
the equipment and perform maintenance
work so that safe and trouble-free opera-
tion of the equipment is ensured and the
warranty remains in effect.
Recycling
Packaging that is no longer required must
be disposed of at the local waste disposal
facility. The packaging is
made of environmentally friendly
materials that can be used as secondary
raw materials.
The moisture analyzer, acces-
sories and batteries, including
batteries on the PCB, may not
be disposed of with regular
household waste. Please
contact your municipal waste
disposal authority or waste management
company. Prior to disposal and/or scrap-
ping of the equipment, any batteries
should be removed and disposed of in
local collection boxes. Sartorius,
its affiliates, subsidiaries, dealers and
distributors will not take back equipment
contaminated with hazardous materials
(ABC contamination) – either for repair
or disposal.
