ORDINARY, SCHEDULED AND EXTRA MAINTENANCE

ROUTINE MAINTENANCE:

Maintenance of PURA™ consists simply of changing the filtering cartridges of the resin container, which is to
be carried out once a year.
Please refer to section 14 of this manual for the sequence of the described operations.
CHANGING FILTERS AND RESINS:
1.
Close the water tap upstream of PURA™.
2.
If PURA™ is installed below the level of the autoclave, please refer to the instructions in Section 6 of
this manual.
3.
Position PURA™ on a flat surface, unscrew and remove the sediment pre-filter and the carbon block
filter (Fig. 1 & 2). Mop up the small amount of water that comes out with paper or rags.
4.
Screw on the new filters, making sure you put each filter in the right position (the carbon block filter is
fitted on the side, Fig. 3 & 4). Screw them on tightly but do not over-tighten.
5.
Remove the safety clips from the fittings of the resin container (Fig. 5) and take out the connecting
pipes by pressing the retaining ring towards the body of the fitting and then pulling on the pipe (Fig.
6).
6.
Remove the spent resin container and replace it with a new one, taking care to keep it the same way
round (Fig. 7).
7.
Insert the pipes in the fittings, press them home (Fig. 8) and insert the safety clips (Fig. 9 & 10).
8.
Turn the two ball valves so that the levers are parallel to the pipes entering and leaving them (Fig. 11
& 12).
9.
Open the water tap upstream of PURA™ and let the water run for at least 1 minute
10.
Turn the two ball valves so that the levers are at right angles to the pipes (Fig. 13 & 14).
11.
Check that the final condition of PURA™ resembles the one shown in figures 15 & 16.
12.
Check that no water is leaking out and put PURA™ in its original position.
ATTENTION: Replacing the filters and resins is absolutely necessary after the signal from
the connected autoclave, or IN ANY CASE AFTER 12 MONTHS so as not to compromise
the functionality of the system and also to preserve the osmotic membrane.
