Warning

Prior to installation, read these

installation and operating instructions.

Installation and operation must comply

with local regulations and accepted

codes of good practice.

Warning

If these safety instructions are not

observed, it may result in personal

injury.

If these safety instructions are not

observed, it may result in malfunction

or damage to the equipment.

Note

Notes or instructions that make the job

easier and ensure safe operation.

Fig. 2 Example of nameplate

4. Installation

Before installation, check the following:

• Do the specifications of the GT tank correspond

to the 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 Lifting the tank

The top of large tanks has a welded-on flange/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.

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 air-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.

Precharge Instructions:

1. Turn the power and water supply off, then turn on a tap to drain the tank before

adjusting precharge.

2. For a pressure switch controlled pump with a differential set up to 30 psi (2.0 bar),

the precharge should be set to 2 psi (0.2 bar) below the cut-in pressure.

3.For a pump controlled by a pressure switch with a pressure differential

greater than 30 psi (2.0 bar), electronic controls or variable speed controls,

the tank precharge should be set to 65% of cut-out or max system pressure.

4. For pressure tanks installed on main pressure, the tank precharge should be set

equal to the main pressure.

5. For hot water expansion applications, the tank precharge should be set equal to

the system ¿ll pressure or the main pressure.

APPLICATIONS

English (GB)

Floor installation

Large GT tanks must be secured to the floor by

means of bolts. Use bolts, washers and nuts that are

suitable for the surface of the floor or base frame.

Use all bolt holes in the base frame when securing

the GT tank.

Tanks with steel bases should be mounted using the

brackets supplied, 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.

Fig. 3 Installation of tank with steel base

Fig. 4 Installation of tank with plastic base

Wall installation

Small GT tanks up to 33 litres must be secured to a

wall or similar.

Fig. 5 Example of wall installation with wall

bracket

4.3 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.

It should 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.

Fig. 6 Precharge pressure

4.3.1 Adjusting the precharge pressure

If the precharge pressure is not suitable for the

application, adjust it as follows:

1. Switch off the pump. Open the nearest tap to

make sure that no system pressure is affecting

the reading.

2. Remove the protective cap.

3. Check the precharge pressure with a suitable

pressure gauge.

4. Release or add air as required to make the

precharge pressure equal to the recommended

precharge pressure.

5. Fit the protective cap to prevent air from

escaping from the tank.

Warning

Before starting work on the product,

make sure there is no system pressure

on the tank.

Disconnect pumps or switch off the

power supply.

Caution

Never exceed the maximum operating

pressure of the tank.

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 to install an isolating valve in

connection with the GT tank.

Fig. 7 Isolating valves

4.6 Maximum operating pressure

The maximum operating pressure of the pump (p2)

plus the actual inlet pressure (p1) must not exceed

the maximum operating pressure of the GT tank (p3).

See fig. 8.

See pump and tank nameplates.

Fig. 8 Maximum operating pressure

4.7 Relief valve

Install a relief valve. Set the relief valve to open at or

below the maximum operating pressure of the GT

tank. This will protect the GT tank and other system

components. The relief valve should be installed at

the connection of the GT tank to the pipe system and

have a discharge equal to the pump capacity at

maximum operating pressure.

Fig. 9 Relief valve

5. Maintenance

The GT tank is a maintenance-free, but we

recommend to check it for damage two times a year:

• Is corrosion visible?

• Are there are any visible scratches, dents, etc.?

In case of serious damage, contact your nearest

Grundfos company.

6. Technical data

See tank nameplate.

8. Disposal

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.

Subject to alterations.

Warning

Before starting work on the product, switch off the power supply.

Make sure that the power supply cannot be accidentally switched on.

Make sure that the tank is pressureless before removing it from the pipe system.

Close the isolating valves and release the precharge pressure through the air valve.

Fault Cause Remedy

1. Frequent

starts/stops.

a) Incorrect precharge pressure. Adjust the pressure according to section

4.3 Precharge pressure.

b) Diaphragm broken. Water escapes

if the air valve is pushed down.

Replace the GT tank.

c) Leakage in pipework. Check and repair the pipework.
