4.2 Location
Always install the GT tank in the discharge pipe as
close to the pump as possible.
Install the GT tank in a frost-free room. It must be
possible to inspect the GT tank from all sides.
The gas-filling valve, water shut-off and discharge
must be accessible, and the nameplate must be
visible.
Install the GT tank so that it is not stressed by the
pipework. If vibrations are likely to occur, we
recommend that the GT tank is installed so that
vibrations are absorbed.
We recommend to follow these steps:
1. Lift and position the GT tank.
2. Level as required (horizontally and vertically).
3. Secure the GT tank.
4. Connect the pipes and fittings.
5. Check/adjust the precharge pressure.
6. Start the pump or application.
No additional loads from the piping system or
equipment are allowed.
