Heating and cooling systems use water as a medium for heat transfer. The water circulates from where the
warm water is generated to the user and back. Even if the system always re-uses the same water, lime and
aggressive materials enter the closed water system when first filling the system, which can damage modern
components.
The filling apparatus filters lime and aggressive dissolved substances such as sulfate, nitrate and chloride out
of the fill-up water. The device operates on the basis of a mixed bed ion exchanger and provides demineral-
ised water that has been completely desalinated. Thus, damage caused by lime and corrosion can be effec-
tivelypreventedintheheatingsystem.
The filling apparatus is equipped with precise meters for monitoring pure water production in terms of qual-
ityandquantity.

The instruments
The pressure reduction valve regulates the pressure of the
untreatedwaterwithregardtothesystem.
Operation: Use the screw driver to turn the adjusting screw
inthecentreof thevalve:To theleft: pressureis reduced; to
theright,pressureisincreased.The higherthe pressure,the
faster the water flows through the fill-up station. The ad-
justedpressureiscontrolledviathepressuregauge.
The battery-powered meter shows the content of the dis-
solvedsubstancesinthewater(totaldissolvedsolids).
Operation: Switch on using the red button on the top left,
then select the measuring point, in the input or output. As
soon as the value on the output is > 20 ppm, then the resin
in the cartridge is exhausted. The untreated water hardness
can be determined via the measuring value in the input and
thecapacityoftheresincanbecalculated.
In order to conserve batteries, the meter turns off
automaticallyafter20seconds.
Resetifnecessary.
The current fill-up station capacity and the total quantity of
the hitherto treated quantity can be read on the flow and
quantitymeter.
Operation: The places after the comma show the litres, the
places in front of the comma show the cubic metre (1,000
litres).Example:0001.248is1,248litres.
The top flow meter shows the quantity of completely
demineralised water, the bottom meter shows the total

Determining water hardness
Water is electrically conductive because it contains dissolved solids (salts). It is mainly lime in drinking
water. Therefore the water hardness can be read from the salt content.

The conversion of TDS into water
hardness only provides an esti-
mated value and is only possible
in untreated drinking water.
Other water contains other dis-
solved solids in addition to lime.
Since PUROTAP removes all salts,
capacity in such cases is much
lower.
Whythecapacitycalculation?
1. In order to know the amount of resin
needed for the demineralisation of the
systemwater.
2. In order to know the capacity of a
resin fill-up that does not have to be
monitored.
3
A capacity of 140 m at 1°fH means that
forawaterhardnessof20°fH,forexam-
ple, thevalue of140must bedivided by
20, in order to determine a capacity of
3
7m . At 40°fH, the capacity would still

be3.5m .

Replacing ion exchanger resin
a) Empty the used resin
If the content of dissolved solids in the treated water exceeds 30 TDS (approx. 2 °fH) according to the
meter, then the resin must be changed. We first recommend that you briefly interrupt the water supply,
shake the cartridge and then slowly turn the water supply back on and fill-up. Thus the residual capacity
canbeasexhaustedaswellaspossible.
Close ball valve 1) and 2) in the cartridge inlet and outlet. Leave PUROTAP profi connected to the
untreated water tap 3).
Connect hose to the drain valve 4) and insert it into the supplied water-permeable collection
sack. Tightly connect the sack to the top of the hose with a cable binder or tape.
Open the drain valve 4).
Open ball valve 1) in the inlet.
Let the resin drain out and then close the ball valve in inlet 1) again.
Let the cartridge have a dry run and close the drain valve 4).
If the collection sack is dripping with resin, then dispose of it in the household waste.

Open the drain valve on the cartridge
only when replacing the resin and only
if a hose is connected to the collection
sack. Under no circumstances, do not
connect the drain valve to a water sup-
plysystem.

b) Fill with new resin
Loosen reinforced hose screws 1) from the apparatus (not at the top on the head).
Hold head 2) by hand and unscrew carefully.
Remove head together with the spray hose 3).
Fill original PUROTAP resin 5) with funnel 4). PUROTAP profi 25 = 1 sack with 25 l, PUROTAP
profi 50 = 2 sacks per 25 l.
Replace head with spray hose. Make sure that the spray hose is pressed into the head until it is
tight and sealed; otherwise, resin will leak into the system.
