9.2 Dismantling in parts and assembly
9.2.1 The replacement of the heat constrainer
WARNING
Discharge the pressure of the cooling circuit in
accordance with the instructions and information provided
by the manufacturer before carrying out the replacement
work at the devices of the sensoric type.
ATTENTION
The danger of injury as a result of the cooling liquid that
will be discharged.
9.2.1.1 Dismantling
1. Remove the nut (4, Figure 901) if necessary and take
off the protection cap (3).
2. Remove the electrical connection of the heat
constrainer (8).

(5) or the plug (3).
4. Apply the measures pertaining to the elements in
dismounted status (refer to 9.1.1).
9.2.1.2 Mounting
1. Screw the heat constrainer (8, Figure 901) manually
to the angle bar (5) or the plug (6).
2. Install the electric connection.
3. Install the protection cap (3) if necessary and tighten it
with a nut (4).
9.2.2 The replacement of the heat sensor
WARNING
Discharge the pressure of the cooling circuit in
accordance with the instructions and information provided
by the manufacturer before carrying out the replacement
work at the devices of the sensoric type.
ATTENTION
