16 Refit the metal thermostat probe
into glass tube of the boiler.
17 Take the one metre length of
16mm tubing and insert through
the hole, item 22 in the cabinet
side. The tubing should extend
approximately 250mm into the
cabinet, roughly level with the
outlet of the condenser.
18 Identify the front boiler level
control WL48, item 27, fig.7, and
connect the outlet to the tubing.
Secure with a tie strap. Ensure that
the Rotaflo Stopcock of the WL48
is closed.
19 Couple the WL48 to the boiler
connection arm with the plastic
coupling and rubber sleeve, item
28. Ensure there are no stresses
from the 16mm tubing on the
connection.
20 Looking inside the cabinet, identify
the vinyl tubing assembly fitted
with 5 numbered screwthread
connectors. Referring to illustration
fig. 8 make the following
connections:–
Connector no. 1 to lower water
inlet of rear condenser.
Connector no. 2 to lower water
inlet of front condenser.
Connector no. 3 to upper water
outlet of rear condenser.
Connector no. 4 to upper water
outlet of front condenser.
Connector no. 5 to front boiler level
control WL48.
21 The tubing assembly is also fitted
with a 1 metre length of 9mm
diameter vinyl tubing. Feed the free
end of this tubing through the
opening, item 21, in the side of the
cabinet.
22 Unscrew the black plastic screwcap
from the WL48 and assemble the
glass funnel WF48 – item 4.
23 Unscrew the black plastic screwcap
and rubber ring from the rear boiler.
Slide both onto heating element
W48H – item 29.
24 Assemble the heater into the boiler
ensuring that the far end is
supported in the glass nodule of the
boiler.
Note: It is not necessary to over
tighten the screwcap and risk
breaking the glass boiler.
25 Pass the electric cable of the heater
up into the electrical control
compartment via the orifice
available. Push the spade terminals
onto the CORRECT PINS of the
connecting strip (refer to fig. 9).
26 Repeat the operation to fit the
second heating element for the
front boiler.
27 Refit the cabinet end panel with all
six screws and washers. Refit
cabinet roof with the six
countersunk screws.
28 Refit the perspex viewing panel.
29 Move assembled A4000D to
desired working location. ensure
there is a space of at least 50cm to
the right of the unit to allow access
to the heating elements.
30 Connect the cold water supply to
connection 18 fig. 7.
Note: The tubing selected should
have a safe working pressure at
least equal to the pressure of the
water supply. The tubing should be
adequately secured by hose clips.
DO NOT SWITCH ON.
31 Electrical Installation
THIS EQUIPMENT MUST BE
EARTHED!
The electrical installation should
only be carried out by a qualified
electrician.
The A4000D is classed as
permanently connected equipment.
The equipment is supplied with
1.5m of flexible, triple core, circular
cable to the following
specification:- 4.0mm
2 , to BS 6500
or equivalent and <HAR> or BASEC
approved.
Connection to the mains electrical
supply, should be via a double pole
isolation switch with a continuous
current carrying capacity of 30A at
250v and overcurrent protection
should be provided by a double
pole approved fuse rated at 30A.
These devices should be sited near
to the equipment and clearly
marked – “Disconnect device for
Aquatron Water Still“
The colour code for the mains
cable is:–
Brown – Live
Blue – Neutral
Yellow/Green – Earth
Mains Cable Replacement
If the mains cable requires
replacement, only specially prepared
spare mains lead obtained from Bibby
Sterilin should be used.
