guarantee that interference will not occur in practice.
Where there is a possibility that injury, damage or loss
might occur if equipment malfunctions due to radio
frequency interference, or for general advice before
use, please contact the Technical Service Department
of Bibby Scientific Ltd.
The Aquatron Water Still complies with the
following European Directives:
89/336/EEC - E.M.C. DIRECTIVE

In order to obtain the optimum performance from your new
Aquatron careful consideration should be given to the intended
location and the availability of services such as water, electricity
and drain.
Please study the following notes before commencing installation.
Before Use
If the equipment is not used in the manner described in this
manual then its performance and operation will be impaired.
Aquatron water stills are designed to operate under the following
conditions:
❖For indoor use only.
❖ Ambient temperature +5°C to +40°C.
❖ Altitude up to 2000m.
❖ Relative humidity not exceeding 80%.
❖ Mains supply voltage fluctuates not greater than ±10% of normal.
❖ Over voltage Category II IEC60364-4-443.
❖ Polluting degree 2 IEC664.
1. Bench Wall Mounting
Aquatron models A4000 and A8000 can be either bench or
wall mounted and a bracket is provided for the latter purpose.
A gap of at least 50cm should be left at the right hand end of
the unit to allow access to the heating elements.
For reasons of weight, models A4000D and A8000 are best
bench mounted, but if it is desired to elevate the unit then a
stout shelf should be used.
2. Electricity Supply
N.B. The Aquatron Water Still is classified as
“Permanently Connected Equipment” and should be
connected to the electricity supply by a qualified
electrician in the manner described in the electrical
installation section of this manual.
The Aquatron stills are available in three models, A4000,
A4000D & A8000.
A suitable supply for the A4000 is rated at 3kW, 220-240v,
50/60Hz~ single phase. A suitable supply for the A4000D &
A8000 is rated at 6kW, 220-240v, 50/60Hz~ single phase.
A4000 units should be connected to the mains supply via a
double pole 30mA Residual Current Breaker with over current
protection (RCBO) isolating circuit breaker rated at 15A.
A4000D and A8000 units should be connected to the mains
supply via a double pole 30mA Residual Current Breaker with
over current protection (RCBO) isolating circuit breaker rated at
32A.
If you have any doubts about the suitability of your supply,
consult a qualified electrician before installing your Aquatron
still.
3. Water Supply
A cold water supply is required for coolant and feed purposes.
This may be from the mains supply or a header tank having a
flow capacity of at least 1 litre/min. for the A4000 and 2 litres/
min. for the A8000 and A4000D. The pressure range should be
within 3-100 p.s.i. (0.2–7 x 105Nm-2).
If the feed water quality is poor and likely to contain particulate
matter, such as rust or silt, it is advisable to fit a pre-filter unit
before the still.
4. Drain
A waste water drain is required. It is important that the
distance between the drain and the water still is kept as short
as possible to reduce the possibility of pressure build-up.
Similarly, the drain pipe from the still should fall straight,
without any kinks or bends, to allow an unimpeded flow. It is
also recommended that the unit is connected to properly earth
bonded water supplies and drainage systems.
5. Storage Tank
A suitable reservoir, the WR20 for instance, is required for the
collection of the distillate. This should be positioned beneath
the still ensuring that the distillate can flow into the reservoir
without hindrance.
6. Maintenance
The location of the still should facilitate easy access for routine
cleaning and maintenance. With regards to the latter, it is
recommended that a space of at least 50cm be provided on the
right hand side of the water still cabinet. This is to allow the
removal of the side cover and replacement of the heating
element.
7. Warranty
Bibby Scientific Ltd warrants this instrument to be free from
defects in material and workmanship, when used under normal
laboratory conditions, for a period of three (3) years. In the
event of a justified claim Bibby Scientific will replace any
defective component or replace the unit free of charge.
This warranty does NOT apply if damage is caused by fire,
accident, misuse, neglect, incorrect adjustment or repair,
damage caused by incorrect installation, adaptation,
modification, fitting of non approved parts or repair by
unauthorised personnel.
This Warranty does not include the heater element which
is only guaranteed for up to 1000 hours in use.

A4000 Assembly
Your Aquatron A4000 has been designed with ease of assembly
specifically in mind. Please study the installation diagram and the
enclosed DVD before commencing the installation. Follow the
sequence of instructions and do not connect the mains electricity
supply until directed.
1. From the outer packaging remove all the components including
the metal cabinet containing the glass boiler.
2. Before unpacking the individual components, identify them on
the check list below:
A4000 Unit containing boiler.
Condenser – WC48/M2
Heater – W48H
Boiler Level Control – WL48
Funnel – WF48
Reservoir Water Level Sensor – WLS
Output Hose Assembly – I/A4000HK/2
Hose Kit – I/WH48/1/B
Wall Mounting Bracket – M510G
3. Remove the perspex viewing screen (Fig. 1, item 1) from the
unit by lifting it up using the finger recess. Remove the internal
packaging carefully. Snip the temporary ties holding the boiler
retaining springs (Item 24).
4. Remove the end plate and lid by removing the retaining screws.
5. Ensure that the sealing O ring and the stabilising O ring are
correctly positioned on the vapour tube of the boiler. Fit the
condenser (Fig. 1, item 4) to the vapour tube ensuring that the
distillate outlet faces the front and the two water connections
are parallel to the unit Fig 1a. When slight resistance is felt
when fitting the condenser, press down slightly on the top
of the condenser until a gap of approximately 19mm exists
between the condenser and the boiler.
6. Take the 1m length of 8mm hose from hose kit I/WH48/1/B
and connect one end to the distillate outlet of the condenser
(Fig. 1a). Secure with a tie wrap. Pass the other end of the tube
through the cabinet hole, Fig. 1, item 21 if to be wall mounted,
or hole, Item 16 if bench mounted.
7. Take the boiler level control WL48 (Fig. 1, item 22). Remove the
end split nut and central part of the boiler plastic coupling (Item
23) leaving the other split nut in place, and the internal seal
in the boiler level control. Ensure the Rotaflo stopcock is fully
closed (screwed down).
8. Take the 16mm earth spigot located inside the A4000 and
place the 16mm tubing part of it into a beaker of hot water for
approximately 20 – 30 seconds; this will make the tubing more
supple. Connect the 16mm tubing to the boiler level control
(Item 22) drain connection (below the Rotaflo stopcock). Secure
with a tie wrap.
9. Take the 1m length of 16mm hose from hose kit I/WH48/1/B.
Place one end into a beaker of hot water for approximately
20 – 30 seconds. Thread the tube through hole (Fig. 1, item
17) until approximately 300mm of tubing is inside the cabinet.
Connect to the 16mm earth spigot and secure with a tie wrap.
10. Pull the 16mm hose back out of the cabinet until a gap of
approximately 5mm exists between the boiler level control and
the boiler connection.
11. Place the boiler plastic coupling split nut and central part onto
the boiler connection. Connect the boiler level control to
the boiler, ensuring that the internal seal of the boiler plastic
coupling is fitted inside the boiler connection and the boiler
level control connection. Tighten the boiler plastic coupling.
12. Loosen the black cap on top of the boiler level control. Fit the
funnel into the top of the boiler level control and tighten the
black cap.
13. Take the hose assembly I/A4000HK/2 and connect the end
marked ‘2’ to the top connection of the condenser. Connect
the other end marked ‘3’ to the boiler level control.
14. Identify the water flow sensor assembly (Fig. 1, item 12) inside
the cabinet. Connect the red connector marked ‘1’ to the
bottom connection of the condenser. It may be necessary to
slightly twist the condenser to release any kinks in the water
sensor assembly.
15. Remove the heater black cap and rubber ring from the boiler.
Place the black cap onto the heater until it is approximately
25mm from the electrical connectors end. Push the rubber ring
onto the heater and into the black cap.
16. Fit the heater into the boiler and screw on the black cap. When
the black cap is tight push the heater through the black cap
until the end of the heater sits in the nodule at the end of the
boiler.
Do not overtighten the screw cap as this may cause the
boiler to break, or push the heater in too far as this may
break the nodule.
