connections onto the heater terminal block. Brown to Brown,
Blue to Blue (Fig. 2d).
SAFETY: It could be possible to mis-locate the heater
crimps on to the heater terminal block tags. Ensure that
the heater crimps are properly located onto the heater
terminal block tags and fully locked on. Attempt to pull
the crimps off the tags to ensure full attachment.
31. Refit the end plate and lid.
32. Move the unit to its working location. Ensure a space of at least
50cm to the right of the unit to allow access.
33. Connect the cold water supply to the mains water inlet. The
tubing selected should have a safe working pressure of at
least equal to the pressure of the water supply and should be
adequately secured with hose clips.
DO NOT TURN ON WATER SUPPLY
34. THIS EQUIPMENT MUST BE EARTHED!
Carry out the electrical installation. This should only be carried
out by a suitably qualified electrician.
The A4000D is classed as permanently connected equipment.
The earth spigots should pass a high current (ie. >200mA).
The equipment is supplied with 1.5m of flexible, triple
core, circular cable to the following specification:
4.0mm², to BS 6500 or equivalent and <HAR> or BASEC
approved.
Connection to the mains electrical supply should be via a
double pole 30mA Residual Current Breaker with Overcurrent
protection (RCBO) isolating circuit breaker switch with a
continuous current carrying capacity of 30A at 250V and
overcurrent of 30A.
These devices should be sited near to the equipment and clearly
marked ‘Disconnect device for Aquatron water still’
DO NOT SWITCH ON ELECTRICAL SUPPLY.
35. Connect the reservoir water level sensor WLS (Fig. 2, item 14) to
the A4000D and secure with a tie wrap. Place the glass pressure
bell in the collection reservoir, following the instructions given
on page 19.
36. Operate the A4000D Waterstill as per Operating Instructions
and check for leaks.
37. Fit the Perspex viewing screen.

20. Take the 16mm earth spigot 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 front boiler level control drain connection (below
the Rotaflo stopcock). Secure with a tie wrap.
21. Take the 1m length of 16mm hose from hose kit I/WH48/3/B.
Place one end into a beaker of hot water for approximately
20 – 30 seconds. Thread the tube through the hole (Fig. 2, item
18) until approximately 300mm of tubing is inside the cabinet.
Connect to the 16mm earth spigot and secure with a tie wrap.
22. 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.
23. 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.
24. Locate the tube assemblies inside the cabinet and connect the
numbered connectors as follows:
1 – Bottom connection of rear condenser.
2 – Bottom connection of front condenser.
3 – Top connection of rear condenser.
4 – Top connection of front condenser.
5 – Front Boiler Level Control.
25. Pass the remaining length of 8mm tubing through hole (Fig. 2,
item 17).
26. Loosen the black cap on the boiler level control. Fit the funnel
into the top of the boiler level control and tighten the black
cap.
27. Remove the heater black cap and rubber ring from the rear
boiler. Place the black cap onto one of the heaters until it is
approximately 25mm from the electrical connectors end. Push
the rubber ring onto the heater and into the black cap.
28. 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 caps as this may cause the
boiler to break, or push the heaters in too far as this may
break the nodule.
29. Repeat steps 27 & 28 for front heater.
30. Pass the electrical cables of the heaters up into the electrical
control compartment via the two orifices. Push the spade
