> Dirty or polluted gauges must be cleaned
before mounting the pressure generator to
prevent contamination on the hydraulic
circuit. Don't clean the tank with alcohol
Option : cleaning bench (Ref.OP0062)
c) Put into service
> the generators are equipped with
precision valves instrumentation, it is
imperative to observe the following
guidelines to keep your machine in good
working condition.
Filling the device with the fluid
. Open valves 5 and turn the capstan 1 in the direction of clockwise until reaching the stop limit
switch forward.
2. Remove the filler cap on the tank
3. Fill the tank with the correct fluid. Use the supplied oil. Don't use other liquids.
> Our devices are mounted and designed to
a standard use. They function with the
fluid provided. Some fluids such skydrol,
castor oil etc... are corrosive and can
damage the o-ring of your device.
On request : we can deliver a device
designed for these fluids.
4. Turn the capstan completely in the opposite direction of clockwise until it reaches the stop.
5. If necessary replenish the tank.
Purging the device
. Open the valves 5 and turn the capstan 1 in the direction of clockwise until reaching the stop
limit switch forward
- Maximum torque applicable abutment valve open = 0,3 Nm
- Maximum torque applicable abutment valve closed = 4 Nm.
When the abutment valve open is reached, turn the wheel valve /4 turn clockwise.
2. Unscrew the filler cap 7 and fill the 3/4 tank with oil(Model CH or CH2) or demineralized
water (model CO) according the pressure generator mode. Replace the cap 7.
Put on the connectors : the reference instrument and the gauge to be tested.
3. Turn the capstan 1 in the opposite direction clockwise until reaching the stop end position.

RE. ENR.110 - Rév B – le 15/03/2014 page : 10
4. Turn the capstan 1 in the direction of clockwise until reaching the end stop before running to purge
air from the system.
5. Turn the capstan 1 dans le sens inverse des aiguilles d’une montre jusqu’à atteindre la butée de fin
de course arrière.
The pressure generator is ready to use.
d) Test run after installing
. Perform a calibration test instrument with a "test" known correct (see chapter procedure) to verify
and validate the operational statues of the pressure generator
Noted : During calibration of instruments with a large volume, the amount of fluid in the pressure
generator may not be sufficient to achieve the desired pressure. in this case the instrument must be
filled as much as possible before being connected to the generator to reduce the useful volume of dluid.
> As an alternative, we provide you with a
hand pump Ref. OP0158 with a reservoir
volume of 327 cm3
2. Lower the pressure by turning the capstan in the opposite direction of the clock hand and remove the
instrument "test". If necessary use the key to start unscrewing the rotating connector
3. The device is now ready to use.

Chap.5 - Cleaning/Maintenance
a) Cleaning
The generator cleaning and checking fluid levels are the only periodic maintenance required. No
additional maintenance should be necessary if all instructions are followed.
We recommend a complete overhaul of the unite every 2 years. This operation can only be
performed by the manufacturer. If necessary, send us your device for maintenance. A complete
assessment of your device will be made and an estimate of rehabilitation will be sent.
Instructions reminders :
- Use only oil H40 or H 5 or Sebacate (depending on model).The guarantees of performance and
operation are insured with the use of these oils.
> wear are protection : protects the eyes
against splashes and projections of the
fluid.
- Don't remove the protective cover.
NOTES : For comparators without isolation valves A', the capacity of the pumps 60 cm3 may be
insufficient to fully complete a high volume measuring device. In this case, a solution with
intermediate valve is possible by interposing it between the bench and the device. We repeat the
cycle as many times as necessary. For these applications, a specific kit can be supplied.
It can also fill in advance before mounting the pressure generator.
b) Maintenance
> Piezometric set
It's designed for extremely narrow limits of accuracy. It's forbidden to disassemble it.
> Valves
Generator and dead weight are equipped with instrumentation valves, it's imperative to observe
the following guidelines :
- Maximum torque applicable abutment valve open = 0,3 Nm
- Maximum torque applicable abutment valve closed = 4 Nm.
When the abutment valve open is reached, turn the wheel valve /4 turn clockwise.
> Tank oil
Make sure the tank contains enough liquid to make the required calibrations. If necessary, fill the
tank with the same liquid as that already used. Don't mix different types or brands of fluids into
the generator and use the recommended oil.
Skydrol, solvents may damage the o-rings mounted on a generator.
Keep clean bench, wipe traces of fluid, and particularly the oil condition in the tank to detect
traces of pollution. If the fluid in the system is dirty, drain the device and remove dirty oil.

RE. ENR.110 - Rév B – le 15/03/2014 page : 16
