Assembly sequence (Ref. fig. 27 and 28)
A) Mount the insulation (pos. 1) of the boiler body and secure
the 2 edges with the contact springs (pos. 2) supplied in the
accessory box, hooking them to the external fabric part of the
insulation.
B) Position the side panels (pos. 3 and 4) with the lower bend
inside the L-shaped profile at the base of the boiler body and
hook the upper part in the plate cuts.
To determine which is the right side and which is the left side,
refer to the cable glands: they must face the front of the boiler.
C) Rotate the cover of the panel board frontwards after having
removed the two screws on the side and insert the electric
inlet cables and the outlet probe capillaries through the slots
at the base.
Fix the panel board to the upper panel (pos. 5).
Fit the upper panel pos. 5, complete with panel board, to the
two sides of the casing.
D) Insert into the conduits the bulbs of the instruments
as
indicated in fig. 28, pass the electric cables through the side
cable glands from the preferred side and wire the panel board
