GB
8.1.6 Installation
Make sure that the labels and markings are clearly visible and legible. Keep a distance at least
200 mm above the gas valve for the mounting of a testing and filling device.
Please consider climate conditions in order to protect the hydro accumulator from sources of
heat, electric and magnetic fields, against lightning, moisture and other adverse environmental
conditions.
For an optimal performance, place the accumulator as close as possible to the consumer.
Preferred mounting position is vertical, gas valve on top.
8.1.7 Assembly
During assembly of the hydraulic accumulator is to be observed:
- make sure that the connected pipe system is assembled free of tension and safely
- make sure that the hydraulic accumulator is properly secured and no uncontrolled
movements can be executed even in the cas of a line break
HENNLICH
- clamps and brackets are suitable for this purpose and deliverable as
accessory
- the hydro accumulator must be mounted so that no external tensions acting on it
8.1.8 Final checks before commissioning
The final review before commissioning must be performed in the accordance with the current
commissioning and operational safety regulations and in line with the laws in the country of set-
up (e. g. use of appropriate safety devices or acceptance test by a recognized test center, etc.)
8.2 Filling with nitrogen
Secure the hydraulic accumulator. Position yourself during filling so that you cannot be damaged
by a possible leak or rupture of the filling.
Especially do not place in the longitudinal axis in front of or behind of the hydro accumulator.
Use for the filling process the
HENNLICH
- filling and test device HFP and therefore the valid
instructions for use have to be noted.
Before testing, the hydraulic accumulator must be relieved on the liquid side!
The nitrogen pressure varies according to the operating or room temperature. Too rapid filling
causes a rapidly pressure increase.
After filling or after the release process, the temperature compensation must be done in the
hydraulic accumulator, before the checking of the pre-charge pressure.
The maximum precharging pressure must not exceed the maximum operating pressure of the
hydraulic accumulator.
