14. Connect the distillate outlet of the condenser
to a suitable collection reservoir, using a
suitable length of 9mm tubing.
A glass reservoir system is available from
Bibby Scientific Ltd. (Catalogue No. Wr20).
Please contact the sales office for details.
15. replace the end panel on to the unit.
16. Take the reservoir control WLS and push the
free end of the rubber tubing onto the
nozzle on the left hand end of the unit - see
figure 1.
use the clip provided to mount the glass
pressure bell in the neck of the distillate
reservoir.
Adjust the height of the pressure bell so that
the open end is approx. 140mm below the
maximum distillate level.
Fitting the Reservoir Control WLS to
Collection Vessels
-
Position the distillate collection reservoir in a
suitable location. This should be below the
water still so that the vinyl rubber tubing
transporting the distilled water from the still
can fall down to the reservoir without
restrictions, kinks or u bends.
-
Take the reservoir Level Control WLS and
connect the free end of the rubber tubing to
the nozzle, of the reservoir pressure switch
located on the side of the stand.
-
use the metal clip to fit the glass pressure
bell inside the distillate collection reservoir.
refer to fig. 4a.
-
Position the bell so that the open end is
140mm below the desired distillate level.
17. Ensure that the earthed spigot wires are
connected to the earth point see fig 1.
18. Turn on the water supply to fill boiler and
check for leaks then turn off the water
supply.

Electrical installation
THIS EQUIPMENT MUST BE EARTHED!
The electrical installation should be carried out by
a qualified electrician. The following method is
recommended.
The earthed spigots should pass a high current
(i.e. >200mA) earth continuity test.
The equipment is supplied with 1.5m of PVC/PVC
flexible, triple core, circular cable with the
following specification, 1.5mm
equivalent and <HAr> or BASEC approved.
The cable gland is designed to accept cable
whose diameter is >7.0mm and <10.5mm. It is
recommended that, at the connection to the
mains electrical supply, there is fitted a 30mA
rCD circuit breaker with a continuous current

Cable connections are shown in figures 3a and
3b. Connect to the line supply noting that the
wires in the instrument lead are coloured in
accordance with the following code:
Blue - Neutral
Brown - Live
Green & Yellow - Earth
Mains Cable Replacement
If the mains cable requires replacement, only
cable with the specification given above should
be used.
For live and neutral leads use bootlace crimps,
size 1.5mm, with a performance conforming to
BS 4G178 part 1, 1984 and part 2, 1986.
For the earth lead use 1.5mm, M4 eyelet crimps
with a performance conforming to BS 4G178 part
1, 1984 and part 2, 1986. A suitable crimp tool
should be used.
Operation
1.
Turn on the cold water supply and adjust the
flow to approx. 60 l/hr. observe that the
water flows via the condenser and into the
boiler. Wait until the boiler has attained its
correct operating level and make sure that
the excess water is flowing freely to drain.
2.
Switch on the heating element. The on/off
switch is located on the front panel - see
figure 1.
3.
After a few minutes the water will start to
boil and distillate will emerge from the
condenser. With new glassware, or after
cleaning, it is advisable to allow this to run
to drain for approximately 30 minutes before
beginning collection.
4.
To turn off the still, first turn off the heating
element but allow cooling water to continue
for a further 10 minutes to allow the Still to
cool.
WARNING!
Do not use this equipment to distil any liquid
other than water.
