TRISECAL 3P DUO 360÷1200
fig. 20
Casing mounting sequence for TS/3P DUO
(Ref. figs. 20 & 21)
N.B. It is suggested to verify that the boiler is
positioned in its final place and that all the
hydraulic connections are made correctly
before starting the casing assembly.
For the composition of the casing packagings
according to the boiler model, see point 2.9.
For the correct positioning join the two boiler
bodies using the two L bars supplied in the
cardboard box of the “Connection kit”.
These L bars will be fitted at both boiler bodies
(joining them at the base in the front and rear
side and keeping then the right distance for
the casing mounting), with the cuts upwards
to receive the casing side panels.
Concerning the mounting of the casings,
make reference to the instructions of fig. 11
for the models TS/3P 360, 480, 600 & 700
and to the instructions of fig. 13 for the models
TS/3P DUO 900 & 1200, replacing only the
two panels for the fitting of the panel board,
supplied in the two standard casings with the
two panels (1 Right, 1 Left) which can be
found in the packaging of the “Connection Kit”.
After removal of the upper panel, fit the panel
board to the two upper front panels (Right
and Left) by introducing the electrical cables
(for the supply, the burners, the pumps, the
mixing valves) and the capillaries of the
thermostats through the hole on the base of
the panel board.
Fix the upper front panels to the upper sides
panels of the casings of the two boilers.
Address the cables of the burners toward the
plates fixed on the side panels, in the external
sides, and stop them on the plates themselves
with a cable clamp type PG 11, fit the burners
plugs (see wiring diagram on pages 28 and 30).
The supply, pumps and mixing valve cables,
must indifferently be addressed toward the
rear part of one of the two boilers and fixed
with the dedicated cable clamps.
Insert the probes of the thermostats in the
bulb holders on the back sides of the boilers
(above the smoke chamber) (Ref. fig. 16); the
probe of the thermometer (pos.1), of the
working thermostat (pos. 2) and the minimum
temperature thermostat (pos. 3) must be
inserted in the largest bulb holder (ø = 15
mm); the probe of the safety thermostat (pos.
4), must be inserted in the smallest bulb holder
(ø = 7 mm).
Pay attention to the identification of the probes:
the boiler n° 1 is the right one (seen from
behind), the boiler n° 2 is the left one (seen
from behind).
We recommend to push all the probes to the
bottom into the relevant bulb holder to improve
its contact. Fix then the capillaries with the
retaining clips (pos. 5).
Close the panel board.
Fit the casing upper rear panels.
Remove the protective paper film from data
plate and ventilation requirement label and
fit them at the top front corner of the most
accessible side panel after removal of dust
from the surface.
The data plate and label are in the
documents envelope.
