1. General
Items included are one Center Heating Expansion
Vessel (fig.1 A) Information on the manufacturer,
year of construction and other technical data is
displayed on the product label (fig.1 B), Scan QR
code on product label to access Installation and
Operating Instructions.
Application
Center Heating Expansion Vessels are intended solely for
use in closed central heating and cooling installations
(with additives based on a glycol to a maximum of 50%).
For the min/max permissible temperature on the
membrane and for the maximum permissible working
pressure and system temperature: please see the
vessel label.
Safety
The expansion vessel is delivered with a pre-charge.
The installation must be carried out by
competent personnel, observing local legislation
and guidelines.
The bracket must be able to carry the weight of a
full expansion vessel.
Install and operate Center Expansion Vessels only
if the vessel is free from visible damage.
In order to keep within operating parameters,
appropriate safety accessories must be fitted.
Disregard of this manual may lead to defects in
the vessel, impairment of its function, personal
injury or damage to property.
Ensure that the maximum operating pressure is
equal or lower than the maximum working
pressure shown on the vessel label.
The connection between the expansion vessel and
the heating appliance must always be open.

2. Installation
1. Flush the installation through before installing the
vessel (never via the safety valve) and check the
installation for leaks whilst under pressure.
2. Expansion vessels with a capacity of 4 - 25 litres
should not be installed suspended from the water
nipple (fig.2 E). Use a Center Heating Vessel Universal
Wall Mount (597815) Center Heating Vessel Pro Wall
Mount (597816) or Center Heating Vessel Pro Fitting Kit
(597817) as appropriate.
3. The Center Heating Expansion Vessel with a capacity
of 35 litres is only suitable for floor standing
installation – do not attempt to wall mount this size
of vessel (fig.3 E).
4. Install the vessel in the return line, as close as
possible to the boiler, on the intake side of the pump.
Install the vessel so that the water it contains cannot
circulate.
5. Apply PTFE tape (fig.5 G) (do not use hemp!)
to the connection of the expansion vessel.
6. If possible, it is advisable to place the optional
connection group in the expansion line for easy
maintenance.

First Use / Commissioning
If the factory-set pre-charge does not match the calculated
pre-charge for the installation, the pre-charge must be
adjusted. The water side of the vessel should be empty
while adjusting the pre-charge.
Remove the cover cap (H) and the valve cap (I) and adjust
the pre-charge to the required setting using a suitable
Vessel Pressurisation Pump. Re-install the valve cap (I) and
cover cap (H). (fig. 9)
In the commissioning sequence:
1. Open the bleed points. (fig. 6)
2. Fill the installation slowly until the water matches
the pre-charge. Bleed the system during filling. (fig. 7)
3. Bleed the pipe to the expansion vessel. (fig. 7)
4. Close the bleed points. (fig. 8)
5. Heat the system to the maximum working temperature
for half a day and bleed regularly.
6. When the water temperature has fallen to approximately
50°C, top up the installation to 0.3 bar above the
pre-charge of the expansion vessel. Ensure that
the filling hose is bled.
3. Maintenance
The expansion vessel must be checked annually. Should water escape from the
safety valve, proceed as follows:
• Check the outward condition of the vessel for damage or corrosion.
• Disconnect the vessel and check the gas pre-charge and, if necessary, set to the
correct pressure as described in point 2: Installation.
In case the vessel or diaphragm is damaged:
• Shut off the vessel from the system.
• Drain the vessel.
• Exchange the vessel
• Check the gas pre-charge and if necessary set to the required value as described
in point 2 Installation.

4. De-installation
1. Allow the installation to cool down and release
the pressure from it.
2. Remove the cover cap (H) and the valve cap (I). (fig. 9).
3. Push the inner valve (J) in to drain the pressure
from the expansion vessel. (fig. 10).
4. Unscrew the expansion vessel (A). (fig. 11).
Caution: The water in the vessel may be hot!
Only check the system when the water has cooled off.
Caution: The weight of the vessel may be greater
than expected, as it may be filled with water.
