there are no obstructions, such as loose
packing or insulation material, in the four
holes in the chamber hearth that the legs of
the balance pan extension pass through.
Position the front brick cover over the front
(see Fig 3.7.1).
In the base compartment, slacken the four
screws holding the balance location plate.
Partly insert the balance into the left side
opening
of the furnace with the ‘front’ sloping
portion of the balance facing towards the rear of the furnace. Connect the combined
balance data and power supply lead marked ‘internal’ to the balance body, lightly
tightening the plug
’s retaining screws, then connect the balance’s earth lead to the
spade connector in the upper rear part of the
recess (see Figs 3.7.4 and 3.7.5)
With the balance and furnace in their intended
final locations, adjust the threaded balance
legs using a spanner until the bubble in the
bubble arm assembly is central and the
balance is level.
