1.3. INTENDED USE
4Y series balances are intended for precise mass measurement under laboratory conditions.
1.4. PRECAUTIONS
•Prior the first use, it is highly recommended to carefully read this User Manual, and operate the
balance as intended.
•Do not operate the touch panel using sharp-edged tools (knife, screwdriver, etc.).

- 13 -
•While loading the balance make sure that loads are placed in the very center of the weighing
pan.
•Load the weighing pan with loads, gross weight of which does not exceed instrument’s
measuring range (maximum capacity).
•Do not leave heavy loads on the weighing pan for a longer period of time.
•In case of failure, immediately unplug the instrument from the mains.
•Balances to be decommissioned, have to be decommissioned in accordance with valid legal
regulations.
•Do not use the balance is areas endangered with explosion. The 4Y series is not designed to
operate in EX zones.
1.5. WARRANTY CONDITIONS

•the balance does not bear company protective stickers.
F. Detailed warranty conditions are listed on a service card.
1.6. METROLOGICAL PARAMETERS MONITORING
Metrological characteristics of the balance require periodical inspection to be carried out by its user.
Inspection frequency is dependent on ambient conditions in which the balance is used, types of
performed processes and accepted quality management system in organization.
1.7. USER MANUAL SIGNIFICANCE
It is very important to read the user manual carefully before switching on and starting up balance
operation, even if you are experienced and have worked with this type of balance before.
1.8. BALANCE USER TRAINING
The balance has to be utilized and supervised only by users who are trained and experienced in
using such type of weighing instruments.

2.TRANSPORT AND STORAGE
2.1. DELIVERY CHECKLIST
Upon delivery it is necessary to check the package and the device, make sure that your package
bears no signs of damage. If it does contact the manufacturer’s representative.
2.2. PACKAGE
Keep all package elements should your balance be transported in the future. Remember that only
original packaging can be used for shipping purposes. Prior packing uncouple any cables, remove
any separable components (weighing pan, shields, inserts). Pack the device components into an
original packaging. The original packaging protects the equipment against potential damage during
transportation.
3.UNPACKING AND INSTALLATION
3.1. PLACE OF USE AND ASSEMBLING
•The balance has to be stored and used in locations free of vibrations and shakes, free of air
movement and dust.
•Ambient air temperature cannot exceed the range of: +10 °C ÷ +40 °C.
•Ambient relative humidity cannot exceed 80%.
•During balance operation, ambient temperature in the weighing room cannot change rapidly.
•The balance has to be located on a stable wall console desk or a stable working table which is
not affected by vibrations and distant from heat sources.
•Take special precaution when weighing magnetic objects, as part of the balance is a strong
magnet. Should such loads be weighed, use under-pan weighing option, which removes the
weighed load from area influenced by the balance’s magnet. The hook for under-pan weighing
is installed in balance’s base.
3.2. UNPACKING
Cut the adhesive tape. Take the device out of the packaging. Open the accessory box, take the
device components out of it.

Caution:
To keep balance mechanism undamaged all operations must be done carefully and gently.
3.4. MAINTENANCE ACTIVITIES
CAUTION!
Cleaning anti-draft chamber while still installed may cause damage of the measuring system.
1. Disassembly a weighing pan and other detachable components (the components differ
depending on a balance type – see Unpacking and Installation section). Be careful while
detaching the components so as not to cause any damages to the balance mechanism. It is
recommended to use tweezers while detaching microbalance’s pan.
2. Using handheld vacuum cleaner remove dust from the weighing chamber (recommended
especially for microbalances).
3. You can disassembly anti-draft chamber panes of XA and AS series is order to clean them
properly – for disassembly instruction read below.
Cleaning anti-draft chamber panes:
Select dissolvent depending on a dirt. Never soak the glass panes in alkaline solutions since they
interact with glass and may cause damage. Do not use abrasive substances.
For organic dirt use acetone first, next use water or detergent. For other than organic dirt use diluted
acid solutions (soluble salts of hydrochloric or nitric acid) or base solutions (ammonium or sodium
base).
To remove ACIDS use protofilic solvent (sodium carbonate), to remove BASE use protogenic solvent
(mineral acid of various concentration).
In case of heavy contamination use brush or detergent nevertheless avoid detergents containing
large and hard molecules which could potentially scratch glass panes.
Use soft brush with wooden or plastic handle exclusively to avaoid risk of scratches. Do not use wire
brush.
At the end of the cleaning process rinse the pane using running water first, distilled next.

- 18 -
Rinsing is a necessary cleaning process stage allowing to remove remaining soap, detergents and
other cleansers from the panes prior their reinstallation.
Avoid drying the panes either using paper towel or forced air circulation since some fibres, grains or
contamination of other type could permeate into the panes thus causing weighing errors.
One shall not use driers when drying measuring glass tools.
It is a frequent treatment to leave glass components on a rack to dry.
Cleaning powder-coated components:
For preliminary cleaning stage you need running water or wet sponge featuring large wholes, this will
help you to remove loose, heavy dirt.
Do not use cleansers containning abrasive substances.
Next using cloth and cleanser-water solution (soap, dishwashing liquid) gently rub the cleaned
surface.
Avoid using cleanser without water since it may result with damage of the cleaned surface, please
mind that large amount of water mixed with cleanser is a must.
Cleaning aluminium components:
While cleaning aluminium components use products acid by nature, e.g. spirit vinegar, lemon. Do not
use abrasive substances. Avoid using hard brush, this may cause scratches. It is recommended to
use microfibre cloth.
While polishing the surface use circular movements. Use clean, dry cloth.
Cleaning stainless steel components:
Avoid using cleansers containing any corrosive chemicals, e.g. bleach (containing chlorine). Do not
use abrasive substances. Always remove the dirt using microfiber cloth to avoid damage of protective
coating.
In case of a daily maintenance:
1.Remove the dirt using cloth dipped in warm water.
2.For best results, add a little dishwashing detergent.
Cleaning ABS components:
To clean dry surfaces and avoid smutching use clean non-colouring cloths made of cellulose or
cotton. You can use a solution of water and detergent (soap, dishwashing detergent, glass cleaner).
Gently rub the cleaned surface and let it dry. Repeat cleaning process if needed.
In the case when contamination is hard to remove, e.g. adhesive, rubber, resin, polyurethane foam
residues etc., you can use a special cleaning agents based on a mixture of aliphatic hydrocarbons
that do not dissolve plastics. Before using the cleanser for all surfaces we recommend carrying out
tests. Do not use products containing abrasive substances.

XA 4Y.A series – order of actions:
Undo and remove top pane
protection, next slide the pane out
of a guide bar.
Remove the left and the right side
pane. Before removing the panes
completely pull protection, see the
picture on the left. The side panes
are not interchangeable therefore
it must be remembered which is
left, which is right. Upon cleaning
procedure completion the panes
must be installed on the correct
side.
Undo the screws protecting the
front pane, next remove it.
Remove the weighing pan and the
pan’s anti-draft chamber so as not
to damage the mechanism while
carrying out the cleaning process.

- 20 -
XA 4Y series – order of actions:
Undo and remove top pane
protection, next slide the pane out
of a guide bar.
Remove the back pane.
Remove side panes.
Side panes shall not be swapped
therefore it is necessary to
remember which one is right, and
which one is left in order to install
them back properly.
CAUTION! Do not remove the front
pane!
Remove a weighing pan, a anti-
draft chamber
, a bottom insert.
Clean the components when
detached. With this your balance
mechanism is protected against
accidental damage.
