3. Installation requirements

Installation and operation must comply
with local regulations and accepted codes
of good practice.
Before installation, check the following:
• Do the GT tank specifications correspond to your
order?
• Are all visible parts intact?
• Is the maximum system pressure lower or equal
to the maximum operating pressure for the GT
tank? See tank nameplate.

3.1 Lifting the product

The top of large tanks has a welded-on flange or nut
in which a lifting eye can be fitted. When the tank is in
place and secured to the floor, the lifting eye can be
removed.

3.2 Location

• The GT tank must be installed in the outlet pipe as
close to the pump as possible.
• The GT tank must be installed in a frost-free
room.
• For inspection purposes, the GT tank should be
accessible from all sides. The air-filling valve,
water shut-off, and outlet must be accessible, and
the nameplate must be visible.
• The GT tank must be installed so that it is not
stressed by the pipes. Should the vibrations occur,
we recommend installing the GT tank in a way
that ensures the vibrations are absorbed.

4. Mechanical installation

4.1 Installing the product

Before installation, do the following:
1. Check that the specifications of the GT tank
correspond to the order.
2. Check that all visible parts are intact.
3. Check that the maximum system pressure is
lower or equal to the maximum operating pressure
for the GT tank.
See tank nameplate.

4.2 Positioning the product

We recommend following 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 pipe system
or equipment are allowed.
4.2.1 Floor installation
Large GT tanks must be secured to the floor with
bolts. Use bolts, washers, and nuts that are suitable
for the surface of the floor or base frame. Ensure that
all bolt holes are used in the base frame when
securing the GT tank.
Tanks with steel bases should be mounted using the
supplied brackets, while tanks with plastic bases
should be mounted through the bolt holes in the base.
For bases without bolt holes, drill four holes at equal
distance in the rim of the base.
