4. Safety precautions
For your own safety, please observe the above safety precautions!
Your Pacific RO system is a modularly constructed, pure water system that
serves exclusively for the purification of tap water.
Do not put the system into operation until you have taken notice of all of the appropriate
information that is given in these Operating Instructions.
Lifting and carrying the pure water system, e.g. to the installation location, should be car-
ried out by two people. To lift it, each takes hold of it under the base plate at two corners.
Note that the manufacturer is freed of all liability for damages that result from improper
operation of the system, or from use of it for other than the intended purpose.
The CE-Mark becomes invalidated should constructional changes be made to the system
or products of other manufacturers be installed in it.
Protect the system from frost. The temperature in the area in which the system is installed
must be at least +2°C and must not exceed +40°C.
Observe all regulations and requirements, including current accident regulations, that are
applicable and appropriate at the installation area, including those for the statics of the
flooring (see weight under „Technical specifications).
The raw water pressure must be at least 2 bar and at most 6 bar, should it be higher, then
an additional pressure reducer must be installed.
DIN EN 1717 requires that water purification systems be equipped with a safety device
that protects against contamination of the drinking water piping.
A grounded 100-250V, 50/60Hz socket must be available.
The installation area must have a drain at floor level with at least DN 50 pipe, otherwise
the manufacturer will not accept any liability for water damage.
Gravity fall to the waste drain must be ensured.
After long standstill periods (e.g. long holidays), the system must be subjected to rinsing
and, if appropriate, disinfection. Refer to the section on ”Cleaning and disinfection“ for de
tails.
When selecting the installation area and installing the system, make sure that there is
sufficient working area around the system for convenient operation of it.
Never look directly into a switched-on UV-lamp, as UV-light is dangerous to eyesight. The

8.3 How the system functions
After switching the ON/OFF-key to on, the system starts either in the production mode or stand-
by mode, according to the filling level in the storage tank.
Feedwater flows into the system under a maximum pressure of 6 bar.
Raw water solenoid valve (V1) is closed in stand-by mode and during standstills. It prevents raw
water from flowing into the system when the system is not in operation and so prevents overflow-
ing of the storage tank (B1).
Downstream of the raw water solenoid valve (V1), the raw water flows past the raw water meas-
uring probe (QIA 300) and on through the pressure booster pump (P1) to the membrane (F3).
The semi-permeable membranes (F3) retain all salts that are dissolved in the water according to
their given retention quota. In addition, because of the molecular size of the membrane pores, an
average 99% retention of bacteria, pyrogens and particles is also effected.
The pure water now flows past the pure water measuring probe (QIA 301) and into the storage
tank. The measured values can be seen in the display.
The feedwater constituents that were retained are led off in the remaining concentrate.
The measuring probe (QIA300) values can be called in the microprocessor control menu.
Pure water is pumped to the user by a downstream tank with pressure pump P2. Float switch LIS
100 senses the filling level in the tank.
Valve V2 has been pre-adjusted in the factory. A change in the adjustment
of this valve could result in damage to the reverse osmosis module.
^ Because of fluctuations in the feedwater temperature and pressure, the set-
ting ting of the pressure hold valve and the concentrate flow that it governs
must be checked and, if necessary, re-adjusted, when the system is put into
operation and at regular intervals thereafter. The measured values must be
entered in the maintenance record.

Your pure water system is equipped with automatic flushing. Flushing is carried out when the
system is switched on, at the end of each production, and also every 12 hours. For this, rinsing
solenoid valve (V3) is opened and the strong flow of water across reverse osmosis module (F2)
sweeps coarse particles and other contaminants away from the surface of the membranes and
carries them with it to drain.
This automatic flushing has a positive effect on the service life of the reverse osmosis module.
An additional advantage of automatic flushing is that it prevents bacterial growth from occurring
in the reverse osmosis module when the system is at a standstill for a long time. For this reason,
we highly recommend that you leave the system switched on over the weekend and during holi-
day times, so that the 12 hour flush can effectively guard against bacterial growth.

9. The installation area
The following criteria must be taken into consideration when choosing the installation
area.
Minimum temperature in the installation area: + 2°C - +40°C.
The surface that your pure water system is to be stood on must be strong enough
to support it (for weight, see "Technical specifications").
A floor drain with waste pipe of DN 50 size (38.5 mm i.d.) is required. Should this not be
available, then a water watcher (article no.: 16.0129) must be installed to protect against
damage from flooding!
An unrestricted gravity flow of concentrate to the floor drain is obligatory.
An electrical socket appropriate to the voltage given on the type plate of the system must
be positioned directly alongside the system. The safety fuse must be appropriate for the
power required (see "Technical specifications").
There must be sufficient working room around the system.
An R ¾“R male thread tap water connection which can be shut off must be installed in
the direct vicinity of the system. Easy access must be ensured
