LIMITATIONS

The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of
the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is
based on the full impeller diameter. The operation of this water pump with variable duty points may be more efficient and economic
when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system information on benchmark
efficiency is available at: www.europump.org/efficiencycharts
WARNING
The electropump cannot be used to move inflammable or dangerous liquids.
WARNING
Verify that the electropump never runs without liquids.
• Max. Temperature of pumped liquid
40° C continuous operation
• Max.On/off cycles/hour
30 equally spaced
• Max. Immersion depth 17 m
CHAPTER 3

INSTALLATION

DANGER - ELECTRIC SHOCK RISK
During installation, verify that the pump is disconnected from the electrical supply.
WARNING
Make sure that the float switch stops the pump, when the min. level of liquid is reached.
WARNING
Make sure no obstacles obstruct the movement of the float switch.
DANGER
This appliance can be used by children aged 8 years or over and by persons with limited physical, sensory or
intellectual capabilities, or with limited experience and knowledge, provided that they are supervised or have
been instructed in the safe use of the appliance and are aware of the dangers involved. Children must not be
allowed to play with the appliance. Cleaning and user maintenance must not be carried out by children unless
they are supervised.
DANGER
Pollution of the liquid could occur due to the leakage of lubricants
• It is advisable to fit a check valve to
prevent the fluid from re-circulating
when the pump is stopped. Avoid using
the electric cable to lift or transport
the pump.
• Use a stainless steel or nylon rope,
suitable to sustain the weight, to
immerse the electropump.
• 1 slot only has been provided to anchor
the electropump.
6
• Maximum dimension of pumped solid
objects 2 mm
• Maximum amount of sand 50 g/m
• Anchor the rope so that it balances the
weight of the electropump.
• It is advisable to connect the electric
cable to the delivery with plastic
straps, at a distance of about 3 m,
when using rigid piping.
• It is also advisable to fit automatic level
controls to prevent the electropump
from running without liquids and
a pressure gauge (suitable to the
electropump model) to verify its
performance during operation.
• Minimum diameter of the well
135 mm DOMINATOR 5"
(without float)
3
• Minimum diameter of the well
100 mm DOMINATOR 4"
(without float)
• The automatic DOMINATOR model is
equipped with a pre-set float switch
(See fig.1). To change the adjustement
range, increase or decrease the free
piece of float switch cable by sliding it
through the seat on the handlebar.
