8.1.3.2 Levels in the distribution tank
The water level must be a minimum of 15mm and a
maximum of 1mm below the dent at the top of the
upper water tray.
In this case, check that the water reaches the overfl ow pipe
of the distribution tank and is continuously removed by it.
Correct level (minimum 15 mm)
If the water level in the distribution tank is too low, raise
the overfl ow pipe or refer to the section «Adapting of the
water pump».
If the water level in the distribution tray is much too high,
check that the holes in the tank are not blocked or fi le
down the base of the overfl ow pipe or refer to the section
« Adapting of the water pump».
8.1.2 Electrical system
We checked previously that the water pump was function-
ing correctly.
Adjust all the circuit breakers to the values corre-
sponding to the nominal current consumed by their
respective
motors.
Adjust or preset the time delays.
Checking the reamer motor :
Check that the motor is correctly coupled.energise
the motor from a separate supply to check :
that the direction of rotation of the rotating parts is
the same as that shown by the arrow marked on the
top of the generator
that the speed of rotation of the reamer corresponds
to the production rate of the machine (see “Specifi
cations”)
Note
The speed of the reamer is the number of
complete revolutions made by all the rotating
parts in one hour.
At the same time, check the operation of the torque
limiter by causing it to trip.
To do this it is suffi cient to trip the torque limiter by manually
moving the roller of its microswitch. To reset the limiter,
hold the reamer motor with both hands and turn it a few
degrees in a clockwise direction
Fig.712.

ping.
Check the operation of the high level safety switch
by tripping it.
8.1.3 Refrigerating checks
8.1.3.1Before initial start up
Check for leaks in the refrigerating system.
Ensure that the expansion bulb is correctly located
on the suction pipe, is held securely and is well
insulated.
In the case of an independent refrigerating system,
that is a generator connected to a compressor
alone,the
fl uid charge of the generator is indicated in
the section (“Specifi cations” under “Connections”).
The installer must provide the charge for the remain-
der of the system.
Initial start up
For generators F15 and F30, the water level in the up-
per water distribution tray is obtained by the fl ow rate of
the water pump and the regulation of its over fl ow tube.
In order to check the water level, switch on the pump
alone after checking that the water level in the base is
suffi cient.
