Installation

5.1 Cold Water Inlet with Inlet Control
Group
5.1.1 Correctly Site the Cylinder
Install the cylinder in an appropriate location,
ensuring all of the recommendations have been
considered (see chapter 4.2).
5.1.2 Install the Inlet Group
The inlet group regulates the pressure of the
incoming mains water supply to the cylinder and
removes any debris that might be water borne.
Note: Between the inlet group and the cold
water inlet on the cylinder NO isolating
device may be fitted, as by doing so
important safety devices could be isolated!
5.1.3 Expansion Vessel
The expansion vessel is mandatory on all EC-Eau
cylinders and can be connected directly to the
cold water inlet group, utilising the flexible hose
supplied with the vessel. The expansion vessel
should always be fitted in accordance with the
manufacturer's instructions. Isolating device/s
must not be fitted between the water cylinder,
the expansion vessel and the cold water inlet
group.
Furthermore, it is recommended to mount the
vessel higher than the cylinder to avoid having
to drain the cylinder when maintaining and
replacing the expansion vessel.

Inlet Group
Note:
installed to the side of the expansion relief
valve on the inlet group. To do this the
blanking plug must be removed and the
expansion vessel connected, as shown in
Figure 4.

5.1.4 Balanced Cold Water Supply
If a balanced cold water supply is required
(recommended) a connection can be taken from
the bottom of the inlet group.
5.1.5 Drain Valve
It is also recommended to install a drain valve in
the lowest point of the cold water feed to the
cylinder. This allows the cylinder to be drained in
a
necessary.
Installation
It is important to check the pre-charge
pressure of the
membrane before filling the cylinder. This
has been factory set to 3 bar. The pre-
charge should be greater than or equal to
3bar.
