NOTICE
Inspections during storage period
In order to avoid rust film on parts made of stainless steel, store them always separately from parts made of C-steel. As far as possible leave the parts in their original packing.
Consider always the allowed maximum floor loading during storage.
Special caution is required when piling wooden crates.
Regular inspection of packing as well as corrosion protection of stored parts and if necessary, complete, repair or replace it. Unless otherwise stipulated, check parts in open-air storage area monthly and parts in covered storage areas every 3 months. Take recordings of the inspections; if damages are detected, initiate suitable measures in agreement with ANDRITZ HYDRO. 1.9.3.1
Storage of machi ne parts
Consider the following when storing machine parts: In op en-air stor age areas
Support the parts approx. 15 – 20 cm from the floor safely on wooden beams, which are covered with plastic.
Tudaya 1 2012
1.9.3.2
Storage and preservation of technical rubber parts
The life cycle of rubber parts can be substantially impaired by several influences and depends therefore to a great extent on a correct storage. Properly treated rubber parts will not change their properties over several years. The following notices apply to the storage of technical rubber parts and have to be kept strictly. NOTICE
Rubber parts, which are stored outdoors, suffer damage after a short period of time due to ozone, UV-radiation and different temperatures. Thus a later use is not possible.
Rubber parts must not be extended, folded, broken or suspended on hooks or something similar. The parts must be stored horizontally. Pressing together must be avoided. Thick-walled profiles are stored in elongated and flat position in order to prevent a permanent deformation. Therefore packing of the profiles in well closed pipes, made of aluminium or hard plastic, is recommended.

The visual check is intended to identify leakages on the nozzle and at the O-type sealing rings (waterside) as well as cracks and abrasion damage. Especially the needles and nozzles are to be checked for damage and abrasion. The nozzle set should always be in a proper condition since comparatively minor damage may have an adverse effect on the jet already. The function of the nozzle drives (opened/closed) and closing/opening times as well as the stroke have to be checked. Jerky movements are not permissible. In case of deviations as against the values at start-up, the reasons and causes have to be identified and remedied. The bearing of the nozzle bar is maintenance-free. 6.5.2.5
Deflector ATTENTION
Prior to reaching into the deflector adjustment device, make sure that the deflector driv e is depressur ized and de-energized, and t hat unintentional movements of the drive are excluded. It must be considered that the deflector drive includes heavily pretensioned springs.

Bladder accumulator: Pressure check and/or accumulator recharge WARNING
The use of nit rogen in co nfined spaces may cause death by suffocation. When using nitrogen, rooms must always be ventilated. It must particularly be observed that nitrogen is heavier than air and hence collects in hollows and depressions. Pressure checks in the bladder accumulator and recharging of the accumulator may only be performed by qualified staff experienced and trained in handling nitrogen and pressure fittings.
NOTE
Only use dry nitrogen from 200 bar pressure cylinders from a renowned gas supplier.

For charging nitrogen into the accumulator, the steps below must now be followed:
7.
Connect hose to gas cylinder to minimess connection C.
8.
If you open the gas cylinder valve now, nitrogen flows into the bladder accumulator. At the same time, the manometer indicates the gas cylinder pressure.
9.
Intermediately close the gas cylinder valve time and again in order to check the bladder accumulator pressure on the manometer. Only charge the accumulator up to the pressure marked on the accumulator head. In systems with a max. oil pressure of 110115 bar, the charging pressure of the bladder accumulator amounts to exactly 67 bar with an oil pressure of 0 bar.
10. If you have achieved the accumulator charging pressure, close the gas cylinder valve.
11. Now close the bladder accumulator valve using hand wheel A. 12. Subsequently relieve the nitrogen pressure from the charging hose and fitting by opening hand wheel D.
