pressure in domestic and industrial applications.
GR-1032823
Example of GT-U tank
2.2 Intended use
• GT-U is a vertical tank for use in cold-water
systems.
• GT-H is a horizontal tank for use in cold-water
systems. The tank has a base plate for mounting
a pump.

4. 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.
4.1 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. It must be possible to inspect the GT tank
from all sides.
• The gas-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. If vibrations are likely to
occur, we recommend that the GT tank is installed
so that vibrations are absorbed.
4.2 Precharge pressure
The GT tanks are supplied from factory with a
precharge pressure. See tank nameplate.
The precharge pressure must be adjusted according
to the actual application and the installed pump.
The precharge pressure must be slightly below the
pump cut-in setting.
Recommended precharge pressures:
• 0.9 x setpoint for fixed-speed pumps
• 0.7 x setpoint for variable-speed pumps.
TM050225
Precharge pressure
4.2.1 Adjusting the precharge pressure
If there is no precharge pressure in the
tank, you must fill the tank with nitrogen.
If the precharge pressure is not suitable for the
application, it should be adjusted according to the
following steps:
1. Use a suitable pressure gauge to check the
precharge pressure.
2. We recommend using nitrogen to achieve the
recommended precharge pressure.
4.3 Maximum operating pressure
The maximum operating pressure of the pump (P2)
and the actual inlet pressure (P1) must not exceed
the maximum operating pressure of the GT tank (P3).
See fig. Maximum operating pressure.
See pump and tank nameplates.
7
English (GB)

TM050227
Maximum operating pressure
4.4 System check
The GT tank must be bypassed if the system
pressure exceeds the maximum operating pressure
of the GT tank during a system check.
4.5 Isolating valves
We recommend installing an isolating valve on either
side of the GT tank.
TM050226
Isolating valves
4.6 Installing the relief valve
1. Set the relief valve to open at the maximum
operating pressure. This will protect the GT tank
and other system components.
2. Install the relief valve at the connection of the GT
tank to the pipe system. It should have an outlet
equal to the pump capacity at maximum operating
pressure.

5. Mechanical installation
5.1 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.
5.1.1 Floor installation
GT tanks must be placed on the floor without bolts.
5.1.2 Wall installation
Small GT tanks of up to 33 litres must be secured to a
wall or similar.
TM050224
Example of wall installation with wall bracket
(product no. 00ID9070)
6. Maintenance
The GT tank is maintenance-free, but we recommend
checking the tank for damage two times a year.
If the tank is removed, when the tank
and /or the system is still pressurized,
make sure that the tank is without
pressure.
Close the isolating valves and remove the
precharge pressure through the air valve.
6.1 Maintenance schedule
• Check the precharge pressure annually.
• Before checking the pressure, make sure that
there is no water in the GT tank (switch off the
pump, and open a tap).
• If water escapes during the precharge pressure
check, the bladder is defective.
GT tank bladder with a volume larger than 80 litres
can be replaced.
6.2 Checking the GT tank for damage
During maintenance, check the following:
1. Is corrosion visible?
2. Are scratches, dents, etc. visible?
In case of serious damage, contact your nearest
Grundfos company.
7. Technical data
See tank nameplate.
8. Disposing of the product
This product or parts of it must be disposed of in an
environmentally sound way.
1. Use the public or private waste collection service.
2. If this is not possible, contact the nearest
Grundfos company or service workshop.
The crossed-out wheelie bin symbol
on a product means that it must be
disposed of separately from household
waste. When a product marked with
this symbol reaches its end of life, take
it to a collection point designated by
the local waste disposal authorities.
The separate collection and recycling
of such products will help protect the
environment and human health.
