1. ASSUMPTION
 Please read these instructions carefully before use.
Damages resulting as consequence of instructions
disregards will not be covered by manufacturer's
warranty.
 Please pay particular attention to the chapter
relating the safety instructions.
 Save these instructions and refer to them anytime your
are in doubt.
2. APPLICATION
These electric pumps have been engineered mainly to
pump coolant liquids and lubricating mixtures into machines
tool systems, machines for production of glass or plastic
materials.
3. USE CONDITIONS
 Liquid temperature must not exceed 50° C.
 These pumps are suitable to be used in to chemically
neutral liquids.
 Do not pump hydrocarbons or any other
inflammable liquid.
 Pumping liquids containing sand or other abrasive
substances may reduce sensitively the life of the
pumps. In this case we suggest pumps type ZC/ZA. In
any case we recommend to assemble a strainer at the
suction and clean the tank periodically.
 Never run pump dry. Dry runs may damage seals
and cause possible hazards of burns to persons
handling the pump.
4. SAFETY
Careless use of electric appliances is always
dangerous. Electric appliances used into water
represent a potential hazards of electric shock. Thus
we strongly recommend to pay full attention to the next
instructions. If you still have doubts, contact an expert
electrician or the manufacturer.
Eventual connection of a power cord must performed
by an expert electrician in accordance of the
regulations is use in your Country

5. INSTALLATION
Installation may result to be fairly complicated therefore it
should be carried out by a skilled person.
Install your pump as close to the well as possible in a dry
and environmentally protected place where temperature
should not exceed 40° C.
 Use the fewest possible elbows and fittings to connect
the pipe.
 The pipe can be either rigid or flexible with smooth
internal surface in order to reduce at minimum the flow
resistance.
 Remove all impurities from the pump housing before first
use.
 Check the free motor rotation before start acting with a
screwdriver into the groove of the fan side motor shaft.
 Sit the pump on a smooth surface and fix it with proper
bolts in order to avoid vibrations.
 Fix properly the flange of the pump to the tank cover with
screws and nuts (fig.2).

tank and the suction hole of the pump (fig.2)
 Fill the tank till cover the submerged pump/end (fig.2).
6. OPERATION
Before starting the pump, the installer have to verify that
voltage and frequency correspond to the rating of the pump.
Make the electric connection with a suitable power cable
and dispose the bridges of the terminal board as indicated
in the following scheme.
In 3/phase motors verify that rotation is the same as
reported on the arrow on the plastic fan cover.
During the pump running verify that liquid don't goes under
the minimum level (fig.2).
7. CLEANING AND MAINTENANCE
Switch off and unplug the pump before any
maintenance. A damage pump must be workmanlike
repaired before further use.
