4. 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 Cole-Parmer
(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. 4b.
-
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
6500 or 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 carrying capacity of 15 amps at
250V, and rated at an overcurrent protection level of 15A . These
devices should be sited near to the equipment and be clearly marked
"Disconnect device for 'Distinction' Water Still".
NOTE: Do not connect to electricity supply with a 13 amp
plug.
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.
