COOLING LIQUID
Remove the tap and pour the liquid coolant into the
radiator; the quantity and composition of the liquid
coolant are indicated in the motor operating manual.
Replace the tap, ensuring it is perfectly closed.
After relling operations, allow the motor to run for
a brief time and check the level, as it may have di-
minished due to air bubbles present in the cooling
circuit; restore the level with water.
To replace the liquid coolant, follow the operations
described in the motor operating manual.
ATTENTION:
The engine cooling system is originally lled with
coolant type:
AGIP ANTIFREEZE EXTRA
During the engine life it is strongly recommended
to use the same coolant type. This is because a
coolant change would require a careful cleaning of
the cooling system, which is not an easy job. A lack
in tacking these precautions would result in the mix
of different additives used in different coolants which
would originate gelatinous substances capable of
obstructing the cooling system.
GROUNDING CONNECTION
The grounding connection to an earthed installa-
tion is obligatory for all models equipped with a
differential switch (circuit breaker). In these groups
the generator star point is generally connected to
the machine’s earthing; by employing the TN or TT
distribution system, the differential switch guarantees
protection against indirect contacts.
In the case of powering complex installations re-
quiring or employing additional electrical protection
devices, the coordination between the protection
devices must be veried.
For the grounding connection, use the terminal (12);
comply to local and/or current regulations in force
for electrical installations and safety.
ATTENTION
Do not remove the radiator tap with the
motor in operation or still hot, as the
liquid coolant may spurt out and cause
serious burns. Remove the tap very
carefully.
