OPERATING AND MAINTENANCE MANUAL
CENTRIFUGAL ELECTRIC PUMP CB SERIES
Fill the pump body and suction pipe completely with liquid through the appropriate
hole (Fig.1)[for the vertical ULTRA models, loosen the vent "a" (at the top) to let the
air out and loosen the needle by-pass valve "b" on the drain plug (at the bottom).
Once completed, close the by-pass needle valve and the vent without using excessi-
ve force]. Do not under any circumstances operate the pump when it is dry. All the
machines, apart from ULTRA series 18 machines, should rotate clockwise (when seen
from the fan side). In the case of three-phase electric pumps, the correct direction
of rotation must be checked and if necessary, the two phases must be inverted. The
single-phase electric pumps can only rotate in one direction, which is factory pre-set.
It will be up to the user to make sure that the performance of the electric pump falls
within the nominal rating indicated on the data plate. If it does not, adjust the gate
valve on the delivery pipe and / or the pressure at which the pressure switch triggers,
if installed.

Maintenance
Disconnect the power supply before carrying out maintenance and/or repairs.
If work has to be carried out on the machine, the gate valves located on the suction
and delivery pipes must be closed and the liquid drained from the pump body through
the appropriate drain holes; adopt suitable precautions for liquids of >40°C. If there is
a risk of freezing, in the case of prolonged machine stops, the tank and all the pipes
must be emptied completely. (Fig. 2) If the tank and / or switch and / or pressure
switch and / or other hydraulic components (hose, fitting etc.) has/have to be repla-
ced, the work must be carried out by qualified personnel. In any case, use components
that are exactly the same as the existing ones, in order to guarantee the safety of the
equipment.
