INSTRUCTIONS FOR TRUCk INSTALLATION OF
F
B
VACUUM PUMPS
BASE FRAME
Please follow these instructions when you install the pump on a truck chassis:
First mode
The pump has to be installed on a steel frame with machined base to ensure the flatness with the pump base.
The frame has to be strong enough to avoid deformations due to the chassis elastic strain. The frame has to
be fixed on the chassis with a correct number of shock mounts. The pump and the cooling air manifold have
to be fixed on the frame without any vibration pad. The pump can be installed and supported using either the
discharge and sucking flanges or the proper feet. If the feet are used, before tightening to the frame, check
that all four feet touch the base properly (< 0,2 mm) and, if needed,
use appropriate shims on the fourth
foot.
Warning: If the pump is placed on an irregular base, malfunctioning may be occur. During tightening opera-
tion check the free manual rotation of the shaft. Use just one bolt per foot.
Second mode
The pump with the manifold has to be installed on a steel frame machined with the flattest base possible and
with four shock mounts. The frame could be fixed directly to the chassis.
All the above indications are very important to avoid damage to the pump while it is running.
Warning: The pump failure may not occur immediately at start-up but at working temperature.
