9. How Pacific-AFT functions
Tap water of max. 6 bar pressure flows into the system.
In stand-by mode and during standstill, feedwater solenoid valve V2 is closed. This prevents
feedwater from flowing into the system when it is not in operation, and so protects the tank
against overflowing.
Semi-permeable membrane A-F2 retains dissolved salts in the feedwater within the specified
retention quota. Further to this, the molecular size of the pores of the membrane ensures Ø
99% retention of bacteria, pyrogens and particles.
Following reverse osmosis, the permeate flows past conductivity probe QIA 300 and through
the downstream purification stages such as deionization, adsorption and UV-disinfection into
the tank.
The retained feedwater constituents are flushed away with the concentrate flow.
The special conductivity probe QIA 301 (with temperature compensation) determines the
conductivity of the pure water (subsequent to the filter cartridge), that can be called to display in
the microprocessor control menu.
Pure water in the tank is pumped by pressure pump A-P2 through the pressure reducer V9 to
the user. This pressure reducer allows the outlet pressure to be adjusted and be read off from
pressure gauge PI 200. The level switch LIS 100 indicates the level in the tank.
.
Pressure hold valve V3 has been pre-adjusted at the factory. Changes to
the adjustment could result in damage to the reverse osmosis module!
Because of possible fluctuations in feedwater temperature and pressure,
the adjustment of the valve and the concentrate flow that it governs must
be checked on starting up and re-adjusted as necessary by Service at
regular intervals.

Your purified water system is equipped with automatic flushing. Flushing is carried out when the
system is switched on, when production is stopped, and every 12 hours. Solenoid valve V4 is
opened and the strong inflow of water across the reverse osmosis module flushes coarse
particles and other contaminants away from the surface of the membranes and carries them
with it to drain.
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 length of time. For this
reason, we highly recommend that you leave the system switched on over the weekend and
during holiday times, so that the 12 hour flush can effectively guard against bacterial growth.
10. Installation location
The following criteria must be considered when choosing the installation area:
Minimum temperature at the installation area, +2°C to +35°C.
The standing surface or the wall where the system is to be stood or mounted must
have sufficient weight-bearing capacity (see Technical specifications for weight)
A floor drain with a DN 50 (38,5 mm ID) waste pipe is required. Should this not be
available, then a water watcher (article no.: 16.0129) must be installed to guard
against water damage!
An unrestricted gravity fall of concentrate to the floor drain must be ensured.
An electrical socket appropriate to the voltage given on the type plate of the system
must be available near to the system. The safety fuse must be appropriate to the
power required (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 room around the system.
A male R 3/4” feedwater connection that can be turned off must be installed in the
direct vicinity of the system.
A wastewater connection must be available in the direct vicinity of the system.

11. Bringing the system into service
1. Use the R ¾“ hose supplied to connect the feedwater inlet
connector of the system (labelled „raw water“) to the prefilter
outlet. Use a further hose (R ¾“ hose, accessory for the pre-
treatment system) to connect the prefilter inlet to the closed
water tap.
2. Use the second R ¾“ hose supplied to connect the
„Concentrate“ outlet of the system to the on-site drain.
Important! The concentrate must be able to flow to drain by
free gravity fall. The drain to the stewer must be max. Are 1 m
above the rinsing water connector of the unit.
09 Use the 6 mm diameter hose supplied to connect the “Recirculation” connector of the
system to the “Recirculation” connectot of the tank.
09 Fit the quick connect coupling in the end of the 8 mm hose supplied and
fasten it on with the hose clip. Fit the coupling onto the lower tank connector for normal
use and listen to ensure that it clicks into position. Connect the other end of this hose to
the “Purfied water” connector of the system.

T Thermo Fisher Barnstead Pacific AFT
Pure water system
20
5. Put now the hose of the sterile overflow Ø 8 mm into the overflow on the tank back and
connect these with the drain.
In order to ensure a perfect function of the sterile overflow, the gas cap
must be firmly locked.
09 Connect the tank supply cable to the 4-pin plug of the system.
09 Open the feedwater tap.
8. Check that all connections are secure and do not leak.
9. Check the feedwater pressure. It must be maintained within the specified pressure
range (see Technical specifications).
Before you switch the system on, read the procedure for rinsing reverse
osmosis membranes supplied in preservative solution in the „Rinsing and
disinfection“ section!
10. Switch the system on at the on/off switch.
11. After a brief flush, your system produces purified water which flows into the tank.
