Check the fixing surface and the cavity for the valve. Permitted values: unevenness 0.01 mm/100 mm, roughness Rmax = 6.3 m. Keep the valve mounting surface and the area clean.
· Before installation, remove the protective cover from the valve ports.
· Check that the valve ports and the O-rings are in the correct position.
· Use fastening screws as indicated in the catalogue, property class 12.9 to ISO 4762.
Parker can supply the correct screw sets, see the catalogue for order numbers.
· Tighten the screws diagonally, torque as specified in the catalogue.
· Any deficiencies of the valve mounting surface may result in operating disruptions. Faulty fixing and incorrect screw tightening torques may lead to the sudden escape of hydraulic fluid at the ports.
The valve must be connected to the equipotential bonding system of the hydraulic system.
Electrical connection
Observe operating instruction D14-2114PD-* in the annex.
Operation limits
The valve may only be deployed with the specified limits of use. The relevant details can be found in the catalogue sheet under "Technical data" and "Characteristic curves".
Observe the ambient conditions. Unauthorised temperatures, shocks, the effects of aggressive chemicals, radiation, unauthorised electromagnetic emissions may result in disruptions and failures. Observe the limits of operation set out in "Technical data".
Excessive temperatures may cause the solenoid to overheat, creating the risk of explosion. To permit adequate heat dissipation, the solenoid coil should not be painted.
Pressure fluids
The following rules applies for the operation with various pressure fluids:
This information serves for orientation and does not substitute user tests among the particular operating conditions. Particularly no liabiliy for media compatibility may be derived out of it.
Mineral oil: usable without restriction.
For operation with the following pressure fluids please consult Parker:
HFA HFB HFC HFD
oil-in-water emulsion water-in-oil emulsion aqueous solution (glycols) unhydrous fluids (Phosphor-Ester)
For detailed information concerning pressure fluids note VDMA-document 24317 as well as DIN 51524 & 51502.
Special gaskets may be available depending on the utilized fluid. In case of insecurity please consult Parker.

Air bleeding of hydraulic system During initial startup, after an oil change as well as after the opening of lines or valves the hydraulic system must be air bleeded.
Filter The function and lifetime of the valve are strongly affected by the cleanliness of the fluid. Purity level class of 18/16/13 acc. ISO4406 is required.
Pay attention to maintenance details!
6. Maintenance
Maintenance procedures may only be carried out by specialist personnel. A detailed knowledge is required of how the machine is switched on and off and also of the necessary safety measures.
Regular maintenance is essential in prolonging the service life of the systems, and safeguards plant safety and operational availability. The following items must be checked at regular and short intervals:
· Oil level in tank · Max. medium temperature · Max. surface temperature · Condition of the pressure fluid (sight check,
colour and smell of hydraulic fluid) · Operating pressures · Preload pressure of pressure vessel (if present) · No leaks at any system components · Condition of the filter elements · Condition of the hose lines · Cleanliness of components After a certain period of service, the hydraulic fluid must be replaced. The frequency of the change depends on the following circumstances: · Type and grade of pressure fluid (ageing) · Filtration · Operating temperature and ambient conditions
Flushing
It is recommended to flush the pipelines by short circuiting the pressure and return lines.This prevents the installation dirt from entering the valve.
Replacement of a coil
In case of a necessary replacement of a coil the disassembly and assembly instructions on drawing 35015707 (see next page) have to be observed. Before exchanging a coil the name plates of old and new coil have to be checked. It must be ensured that only coils with identical voltages are used. Available coil kits are: AK-D1FBCJEE318 AK-D1FBCKEE318 The coils of series D1FB*18 are suitable for D*1FB valves of series 12 and 13.

7. Troubleshooting
A systematic approach must always be used in the troubleshooting process. Begin by answering the following questions:
· Does anyone have practical experience with similar faults?
· Have any of the settings been changed in the system?
Now try to identify the fault using a prioritised list of the most likely causes.
· If you suspect that the valve is not moving freely, you should flush the valve with clean pressure fluid.
· A systematic approach should always be adopted when troubleshooting a hydraulic system.
The work must only be carried out by specialist personnel because detailed knowledge of the function and structure of the system is required. Always think carefully about changing settings or removing components. Before starting work, check that the system was working correctly before the fault occurred.
Following any repair, commissioning must be carried out as instructed.
