3.
Take the Glass Boiler (Part No. 2) ensuring that the two Silicon rubber
'O' rings (Part No. 5) on the vapour tube are in place. The smaller
silicon rubber 'O' ring (Part No. 6) to be seated on the top groove of
the vapour tube of the Glass Boiler (Part No. 2). The bigger silicon
rubber 'O' ring (Part No.6) is to be adjusted to a distance of approx.
35mm from the top surface of the Glass Boiler (Part No. 2) or such
that when the Glass Condenser (Part No.3) is placed over the vapour
tube it does not shake. Take the metal Heater (Part No. 4) the Metal
Flange (Part No.8) the Neoprene Rubber Gasket (Part No.7) and the
Rubber Collar Insert (Part No. 10) and assemble as shown in the Fig.
No. 1.
(a) Place the Metal Flange (Part No. 8) (Flat side facing the Boiler) over
the tapered Glass neck of the Glass Boiler. (Part No. 2).
(b) The Rubber Collar Insert (Part No. 10) is bent around the tapered
Glass neck and into the Metal Flange (Part No. 8). The Metal Flange
(Part no. 8) is pulled and inserted towards the end of the Glass Boiler
(Part No. 2) neck so that when the Metal Flange (Part No. 8) is pulled,
the Rubber Collar Insert (Part No. 10) seals on the neck.
(c) Place the Neoprene Rubber Gasket (Part No. 7) over the metal
heater (Part No.4) and insert the metal heater (Part No. 4) through the
tapered Glass neck and into the Glass boiler (Part No. 2).
(d) Secure the Metal Heater (Part No.4) with the three Stainless Steel
Bolts (Part No. 9) provided. Care should be taken not to over tighten
the bolts. The heater axis should be parallel to the boiler axis.
4.
Place the Glass Boiler (Part No. 2) and Heater assembly in the cradle
of the powder coated stand (Part No. 1) It plug not installed connect
the Metal Heater (Part No. 4) cables to the pins of the 13 amps
connector as per circuit diagram page. 9.
