2. Installation.

Please observe the regulations concerning the installation of your water softener. Check that
you have allowed space for access to the unit for possible future maintenance. This
installation may require plumbing work and will require an electrical outlet to be fitted near the
system. Only attempt this if you have the necessary skills.

2.1 Pre-installation checks.

The area needs to be level, frost free have access to electricity and an open drain. Check the
incoming water quality is within any parameters specified for that media (see technical
information at the back of the manual). In addition to this check the incoming water pressure
is between 2 and 8 bar (preferably approx. 4 bar) and the water temperature is between 3ºC
and 45ºC.

2.2 Fitting the Bottom Distribution Systems.

Fit the bottom distribution systems into the vessels – the bottom screens should be pre glued
to the riser tubes (fig A.1). If the system uses bottom laterals (typically 16" diameter and
above) these need to be assembled inside the vessels (fig A.2), Move the vessels to their final
positions as they will be difficult to move once the media has been added.

2.3 Adding the Media.

Block the top of the riser tubes to stop media getting down the tubes (see fig A.3). Add about
1/3 by volume of water to the vessels so when the media is poured in it doesn't damage the
bottom distribution systems. Add the media supplied but make sure there is free space left
above the media so when the system is backwashed the media can expand into the space
and any sediment or contaminants can be backwashed away (there may be media left over).
Unblock the riser tubes.

2.4 Fitting the Valves.

Add a small amount of silicone grease to the valves outer and inner o-rings (fig A.4 & 5).
