4.3 MAINTENANCE OPERATIONS
ATTENTION
Change or restore all components damaged, wear or that don’t work properly.
Tighten all the bolts in accordance with the tightening torques and using a torque wrench.

ENERAL
I.a All components: cleaning, deterioration and wear

Check, visually, the condition of the components and clean, using a rag, water and neutral
soap.
I.b Signs, labels, signals and diagrams

Check, visually, that all labels, signs, diagrams, and documents are in the correct position,
clearly visible and undamaged. If necessary clean using a rag, water and neutral soap.

ACHINE ROOM
V.e Devices to detect the unintended movements UCM (A3)

Verify that the unintended car movement detection devices (UCM) work properly by performing
the necessary tests, controls and measurements.
- See § Protection against unintended car movement [EN81-20 §6.3.13]
(Also refer to what is indicated in the control panel manual).

VI.c Shut-off valve

Check the seal of the shut-off valve as follow:
- Close the shut-off valve (R/S) and open the pressure gauge tap (6)
- Fully discharge the pressure by pressing the push-button on the valve (VMD)
- Check that the pressure level on the manometer (MAN) is zero
- Close the pressure gauge tap (6) and open the shut-off valve (R/S)
VI.d Pressure gauge tap

Check the seal of the EN81 pressure gauge shut-off as follow:
- Close the shut-off valve (R/S) and open the pressure gauge tap (6)
- Fully discharge the pressure by pressing the push-button on the valve (VMD)
- Close the pressure gauge tap (6) and open the shut-off valve (R/S)
- Check that the pressure level on the manometer (MAN) is zero
VI.e Working pressures

Check that static and dynamic pressure values correspond to those declared and found at start
up as follows:
- Open the pressure gauge tap (6)
- Check the maximum static pressure value with lift stopped and car with nominal load.
- Check the dynamic pressure value by moving upward the system.
- After the measurements exclude the pressure gauge (MAN), closing the pressure gauge shut-
off (6)
VI.f Valves on power unit

Check the seal of the valve seals as follow:
- With the fluid at room temperature, close the shut-off valve (R/S)
- Open the pressure gauge shut-off (6)
- Check that the pressure on the pressure gauge (MAN) does not drop more than 4 bar in 5
minutes
The execution of the test at point VI.f, ensures that all the valve organs subjected to
pressure, including those not visually controllable, are intact.
This test is specific of the maintenance and is not the "Pressure test" [EN81-20 §6.3.10]
which must be carried out before putting into service the system.
