System Components in Flow Chart
Principle
The hydraulic diagram (flowchart) of the Adrona Q-Front N water purification system is shown in
Q-Front N Trace and Q-Front N HPLC/ Bio/ Bio UF flow charts above.
The input valve controls intake of feed water from the tap. The first purification stage consists of the
pre-filter cartridge (part no. 10411) including activated carbon intended to remove particles, free
chlorine, organics and colloids. A pressure switch controls feed water pressure.
The boost pump is used to maintain pressure at the level necessary for the efficient operation of the
reverse osmosis membrane, deionization module (part no. 10311), and UV sterilization module (Bio
configuration only). The feed flow goes to the membrane where it splits into two parts: the permeate,
diffused through the membrane, and the concentrate which passes over the membrane, carrying away
contaminants to drain. The permeate goes to the third purification step – deionization module (part
no. 10311) where the remaining dissolved contaminants are removed.
Before entering the tank, water is sterilized by an UV lamp (Bio configuration only, also available as an
option). Water quality is controlled by Grade II water conductivity sensor. LCD display provides
information about the system status.
Purified water is stored in the tank. Water in the tank meets the requirements of ISO 3696 Grade II.
In order to obtain Grade I water, there is a recirculation loop connected to the tank.
 For Trace modification this loop includes recirculation pump, polishing module (part no.
10031), Grade I sensor as well as dispense port with microfilter (part no. 10012).
 HPLC, Bio and Bio UF configuration additionally includes photooxidation module (part no.
10018) and TOC monitor.
 Q-Front N Bio system has an ultrafilter (part no. 10120) instead of microfilter.
 Q-Front N Bio UF system has an in-line ultrafilter (part no. 11200) before microfilter.

Male NPTF
Feedwater should be filtered with 1 μm sediment filter. If the filter is not installed, the input strainer
may become clogged thus blocking the water flow.
Check if sediment filter is installed in tap water
supply line. There should be at least one sediment
filter (pore size 1 μm). The sediment filter is
usually available from a local plumbing store. If
you cannot obtain a sediment filter locally, you
can order tap water line pre-filter set from
Adrona. The part number is 10170 (carbonpp/ PP
1 μm) or 10171 (polyphosphate/carbonpp/1 μm).
Feedwater connection
Feed water hardness does affect produced water quality. Operation of the system with hard feed water
may result in pre-mature clogging of reverse osmosis membranes and reduced Grade II or Grade I water
flow.
Therefore, it is strongly recommended to install a water softener or polyphosphate filter if
water hardness is above 160 ppm.
Feed water connection port has to be 1/2” NPTF (male) thread. The system is equipped with feed water
tube (1/4’’ OD) and adapter for 1/2” NPTF (female) water supply connection. The feed water tube
should be connected to the 1/4” John Guest port of the adapter. Feed water connection port should be
equipped with a valve allowing shutting off water supply.

PRE-INSTALLATION
8
Drain pipe should be lower that the level of the instrument and the level of the OVERFLOW
port of the tank. The water purification system has 1/4” OD drain pipe. The OVERFLOW port
of the tank is intended for 3/8” OD pipe with stem elbow 3/8”.
Feed water supply connector and drain should be within 3 meters from the installation site.
Please note that in case of Q-Front N system pre-filter Q (part no. 10411) module pre-
mature clogging, we will ship the new pre-filters under warranty only if we get a photo of
the sediment filter installed in the tap water line.
Site requirements
The system requires up to 350*390*540 mm (W*D*H) space on the bench. The system is equipped
with water storage tank “Pro” that requires up to 390*440*600 mm (W*D*H) space. The tank can be
placed under the bench. The system can also be mounted on a wall to save space on the laboratory
bench.
Environmental requirements
The water purification system is intended for indoor use only, in an environment that has
nonconductive pollutants only.
Ensure that the site is maintained under the following conditions:
Condition Acceptable range
Temperature
15 to 30 °C (59 to 86 °F)
Humidity 20% to 80% relative humidity, noncondensing
Water leakage safety
- Make sure that all water connection tubes are kink-free.
- Make sure that all water connections are tight.
- Feed water supply connector and drain should be within 3 meters or less from the installation
site.
- Feedwater connection port has to be 1/2” NPTF male thread.
When installing the tank, connect the fitting marked OVERFLOW to the drain. Make sure that
the drain level is lower than the OVERFLOW fitting level. This will prevent water leakage in
case of tank level sensor failure.
A 1 m sediment filter has to be installed in the feedwater supply line. Failure to install the
filter may result in clogging of the strainer inside the system and water flow blockage.

UNPACKING

UNPACKING
Remove packing materials carefully and retain for them future shipment or storage of the unit. Examine
the unit carefully for any damage incurred during transit. The warranty does not cover in-transit
damage.
Due to the unit’s weight its unpacking and installing is to be carried out by two persons.
When opening the shipping box, we advise to compare received parts with the Packing List
included.
Contact Adrona if any part is missing.
INSTALLATION
Preparation of the System
Review “Pre-installation requirements” chapter above.
Unpack the water purification system and place it on the laboratory bench.
Remove the protective packing materials.
Introduction to John Guest tubing system
Adrona water purification systems are equipped with John Guest push-fit fittings and tubes. We will
use abbreviation JG for John Guest parts in further text.
To make a connection, the tube is simply pushed in
by hand; the unique patented John Guest collet
locking system then holds the tube firmly in place
without deforming it or restricting flow
Push the tube into the fitting, to the tube stop
Pull on the tube to check it is secure. Test the
system before use
To disconnect, ensure the system is depressurized,
push the collet square against the fitting. With the
collet held in this position the tube can be removed
