3. Safety information
For your own safety, please observe the above safety precautions!
Each system of the Puranity PU 15 series is a modern ultrapure through out water
system, exclusively designed for the purification of tap water of drinking water
quality.
Please do not start to install and operate your system until you have read through
the information given in these operating instructions.
Please note that the manufacturer is freed from all liability when the system is used
for other than the intended purpose and/or is improperly operated.
Lifting and carrying the ultrapure water system, e.g. to the installation location,
should be carried out by two people. To lift it, each takes hold of it under the base
plate at two corners.
The CE-mark is invalidated when constructional changes are made to the system
or foreign products are installed in it.
Protect the system from frost. The temperature at the installation area must be at
least + 2°C.
Observe all general rules and regulations that are valid at the installation location,
including the current accident prevention regulations.
The feedwater pressure must be min. 1 bar and max. 6 bar. An additional pressure
reducer must be installed should it be higher.
According to DIN EN 1717 (for German and Europe), water purification systems
must be equipped with a device that safeguards the tap water against
contamination.
A suitable electric socket must be made available for the system (refer to Technical
Specifications).
The installation area must have a drain floor or a gravity floor with at least
DN(nominal diameter) 50 pipe and which allows free run off. Should no such drain
be available, we recommend the installation of a water watcher (article no. 171-
1126), otherwise the manufacturer will not accept any liability for water damage.(
specifically for Europe)
When the system is to be wall-mounted, please previously check that the wall has a
sufficient load-bearing capacity (refer to Technical Specifications for the weight).
The ultrapure water system only be mounted on a concrete wall or a solid masonry.
The maximum operating temperature of the system is 40°C.

4
If neither a floor drain is not is available, then proceed as follows during longer
system standstills (e.g. long holidays):
Switch the system off (unplug the mains plug).
Shut off the supply of water to the ultrapure water system.
Do not re-start the system with the water supply still in the shut off condition, as the
pump would then suffer damage. The manufacturer will not accept any liability
should this occur. When restarting your system, please open the feedwater to the
ultrapure system and follow our sanitization instructions to put your system into
operation.
When installing the ultrapure water system, ensure that there is sufficient working
room around it for problem-free operation of it as well as for filter replacement,
checking connections etc.
The warranty is valid for a period of 2 years!
Never look directly at a switched-on UV-lamp, because UV light endangers
eyesight!
Never switch the UV-lamp on when is has been taken out of the metal cylinder!
3.1 Warning
Installing the appliance incorrectly, making incorrect settings on it or modifying it can
lead to damage, injury or even death.
Do not put your fingers in socket of electrical connector because a electrical shock
you can have.
Do not swap any electrical parts of the unit when it is on and works, because there is
a danger of electrical shock exist.

4. Use
4.1 Intended use
Puranity PU 15 ultrapure water systems are a reaction to actual user needs, the continually
increasing requirements that water of ultrapure quality must fulfill, the increasingly strict
demands resulting from technological advances and the need for user-friendly systems and
complete solutions.
Puranity PU 15 systems have therefore been solely and specifically designed for the
production of ultrapure water which is free of particles, salts and organic compounds and is
sterile filtered.

7. Describtion of how the systems functions
Puranity PU 15, UV/UF, UV
Tap water that has been pretreated by reverse osmosis, ion exchange or distillation flows
through a pressure reducer and into the ultrapure water system, where the electric
conductivity of it is monitored. A pump forces this feedwater through UV-photooxidation (only
with Puranity PU 15 UV and Puranity PU 15 UV/UF) and a filter cartridge. Following this, the
water is further pumped through an ultrafiltration module (only with Puranity PU 15 UF and
Puranity PU 15 UV/UF) and on past a special conductivity measuring cell equipped with
temperature compensation which continuously measures the conductivity. When treated
water is dispensed, it flows through a sterile filter before exiting from the ultrapure water
outlet. The water inside the system is recirculated at regular time intervals during the
“Interval” mode.

8. Installation
8.1 Installation area
Take the following criteria into consideration when selecting the installation area:
Feedwater pressure, not below 0.1 bar, not above 6 bar.
The feedwater pressure must not be allowed to go above 6 bar. Install an
additional pressure reducer when the feedwater pressure is higher.
Minimum temperature + 2°C.
Level standing surface
A smooth wall is required when the system is to be wall-mounted.
The standing or wall surface must be strong enough to hold the system (for
system weight, see "Technical Specifications")
A gravity drain with a DN(nominal diameter) 50 size (id 38.5 mm) waste pipe is
required.
When no such floor drain is available, install a water watcher (article no.: 171-
1126) to guard against water damage! (specifically for Europe)
Free gravity flow to drain must be ensured!
An electric socket with protective conductor must be available for connection of the
system to the voltage supply (see Technical specifications).
Position the system so that there is no difficulty in separating the
device from the electric mains.
There must be sufficient working space around the system (filter replacement
etc.).
The system must be easy to operate and check.
R 3/4" pre-treated-water connection.

8.2 Installation
1) Feedwater connector Hose, 8 mm od
2) Rinse water connector Hose, 8 mm od.
3) Connection power supply 4-pin 24V DC
4) Sterile filter
5) Filter cartridge
Proceed as follows to install and start your Puranity PU 15 ultrapure water system:
Either stand the system on the intended surface or hang it on a wall using the wall-
mount which is available as an accessory.
Press the push-button of the cartridge cover to unlock the cover. Remove the cover.
Remove the stoppers from the filter cartridge (5) which is supplied with the system
and save them for possible return of the spent filter cartridge (only when it is to
carry out waste disposal).
Fit filter cartridge (5) in the free space at the back of the compartment, then plug the
2 quick-connect couplings onto the filter cartridge connections so that they audibly
snap into position.
Use the R3/4" feedwater hose kit to make connection to the feedwater connector
(1).
Position the dirt-trap sieve (from the hose kit) in the 3/4" threaded connector of the
feedwater hose and screw this connector to the water tap which can be turned off.
