I) Checking at the delivery
Check at receipt that the packaging has not been damaged, that the delivered visual level controller is in accordance
with your order and that the material is not damaged.
II) Storage
The visual level controllers can reach the site several months before commissioning. Performance may be degraded
if special care is not taken in their storage and protection.
It is recommended to store the visual level controllers in a clean, closed, protected from weather and projections of
sand, dust and other solid particles. Leave them as much as possible in their original packaging. The plugs,
protections threads, plastic envelopes, will be removed at the time of installation. Avoid impacts on the sealing
surfaces of the threads.
III) Assembly of the visual level controller
1) The visual level controllers must be handled with particular care. Prevent the ingress of foreign bodies in the visual
level controllers reflex glass indicators during installation and operation.
2) This equipment can not be installed in an explosive area.
IV) Instructions
1) It is strictly forbidden to neutralize the mechanism of the visual level controllers.
2) Any foreign body must block the entries of the visual level controllers.
3) The visual level controllers must be installed in a place where there is no risk of shock or water hammer which
would endanger working.
4) Insulate the equipment if the temperature of contact requires it (for staff in case of explosive atmosphere in or out
of the equipment), and allow only the access to the approved staff. For the equipment, it is imperative to stay in a
beach temperature indicated on the identification plate (Rep. 3) or failing on the product data sheet. Take care not to
have fluid in changing state (gel) may damage the tube.
5) It is imperative to respect the conditions of use stated (pressure, temperature, fluid) during your request to our
services (no corrosive fluids or fluids which may cause significant wear, no unstable fluids from which decomposition
may cause risk, do not use several fluids likely to react each other to generate derivatives leading to an explosive
atmosphere or may not viscous fluids solidify at a moment or another).
6) Limit as much as possible the tensions due to failure alignments of the piping connections system.
7) It is necessary to eliminate any previous and post pressure before removing the level indicator and be sure not to
create an explosive inside or outside the reflex glass indicator. The staff operating the setting up of the visual level
controller will be trained to perform this operation and will wear all necessary protections linked to the carried fluid.
8) Do not let the mechanism in intermediate position for a long time to avoid any phenomenon of cavitation and/or
erosion.

9) Do not modify the documents furnished by AUTEXIER (instructions, metal plates, certificates etc.).
CAUTION: AUTEXIER is not anymore responsible of the good working of the level indicator if this
one has been dismantled or modified by a person not approved by AUTEXIER.
V) Operating / Maintenance
1) It is imperative to maintain the visual level controller clean and ready to operate. This includes checking
periodically that no foreign body clogs the pipes and that the installation is free as possible of deposits and
impurities.
2) For references 149/449, 150/450, 184, 3184, 2276, 276 and 278 the packing gland (parts 12, 13 and 14) is
mounted by us at the factory. However, during the life of the equipment, it may be necessary to tighten packing nut
14; or to change of the packing 12.
To do this, after taking care to let the material to ambient temperature and making sure that the system has been
correctly bleeded, unscrew the nut 40, remove the handwheel 8unscrew the packing nut 14 remove the packing
gland 13, remove the sealing gasket 12, put new packing in the bonnet 2, replace the packing gland 13, screw
packing nut 14, put the handwheel 8, screw the nut 40. Packing glands must be tightened at the setting up of
operation and just enough to seal.
This maintenance should be carried out by qualified and duly authorized staff. This disassembly reassembly is the
only one authorized by AUTEXIER under conditions that parts are supplied by us, that the handling of the equipment
is made at ambient temperature, that the operator uses material in accordance with the classification of the area in
which it operates (potentially explosive), and it is well assured that the system has been properly purged beforehand,
without creating an explosive atmosphere during operation.
VI) Guarantee
All our products are guaranteed during twelve months from the delivery against any defect of material or
manufacturing, when the conditions of use are respected: this guarantee is limited to the replacement or to the repair
by our company of the defective recognized parts. We decline all responsibility in case of non respect with our
instructions.

VII) Marking
After being tested and adjusted, each visual level controller is sealed by AUTEXIER. If another agency makes a
mark by punching the visual level controller should not be damaged. Poorly executed, deformations could make tap
fugitive, or inoperative. Punching of thin walls is prohibited.
Level indicators are identified by a label with the following information:
- The date of shipment
- Specifications:
1- Designation: Reference of visual level controller
2- Calibration certificate number and du number of
declaration of conformity to directive 2014/68/EU
3- Maximum condition of use from reflex glass
indicator
4- Envelope pressure test from visual level controller
5- Set pressure (xx for this product)
6- Group of fluid G for Gas / L for Liquid or S for
Steam
7–Inlet nominal diameter and outlet nominal
diameter
- with number of identifying the notified body 0038 (Lloyd's)
It is imperative to respect the conditions of use stated on the rating plate (pressure, temperature, and fluid)
under penalty of equipment damage and void the warranty.
